MODIFICATIONS FOR PASSED HAND:
All the same, but major transfer followed by 3m is nat F1.
--------------------------
Handling Interference:
---------------------------
1. Artificial Double
A. Redouble and continuations
a. XX = 8+ HCP
b. opponents cannot play undoubled (forcing pass)
B. 2-level suits are transfers
a. wide-range of strength, but not a XX, freak, or penalty-seek
b. over a 2D/2H transfer, continuations are systems on but a new suit is F1 (may have both majors)
c. over a 2C transfer, NS by responder is F1
d. over a 2S transfer, opener bids 2N with min and 3C with max, and continuations are as normal
(3D/M = shortness)
C. 2N shows 5+4+ minors, weak or GF (later 3M = shortness GF)
D. 3-level suits are nat preemptive
E. Higher bids are normal systems on
E.g.
1N-(X)-XX-(2C); P-(2H)-3D = 8-9(-), 5+D NF
1N-(X)-XX-(2D); P-(P)-2S = 8+, 4+S, F1
1N-(X)-XX-(2H); P-(P)-X-(P; 3C = 16-17, 5/6C, GF
1N-(X)-XX-(2H); P-(2S)-P-(P); X-(P)-3D = 9+, 5+D, GF
1N-(X)-2C = 0+, 5+D
1N-(X)-2D-2H-2S = 8+, 5+H-4S, F1
1N-(X)-4H = 8-10, 6+H
2. Penalty double
A. Pass/2C are the same as over double of our weak NT, except Pass, which asks partner to pass 100%. 2D and
higher are the same as over the artificial double above.
e.g.
1N-(X)-XX-(P); 2C = forced
1N-(X)-2H = 0+, 5+S
3. Natural 2-level overcall
A. Direct double is negative, 5(+)+ HCP, however responder's double is penalty if 4th seat has balanced over 1N.
Later new suits by responder are NF.
B. New suit:
a. 2-level NS is nat NF, opener can continue only with maximum and fit
b. 2N = invit+ transfer over (2m), Lebensohl over (2M)
c. 3-level NS (even a jump) except 3S is a transfer (transfer to their suit shows the next higher suit)
with at least invite strength, xfer to a minor denying other major if overcall was (2M)
d. 3S over 2m shows 4H-5+om, GF, while over 2H is a transfer to clubs (over 2S, 3H is this transfer)
forcing to 3N or 4m
e. 4m = 6+M slam interest - if the major is impossible, it shows shortness in oM (their suit)
f. 4M = to play, no slam interest, wants to declare
g. 3cue = asks stopper
h. after a transfer, continuations follow general principles, just as after 1C-(2S), e.g.
C. Lebensohl
a. weak hand with any suit 6(5)+ unbiddable at the 2-level
b. over (2M), a GF Stayman hand
c. opener must bid 3C, unless he has a hand that can try for game opposite a C signoff
d. over 3C by opener, responder's cue shows 4oM without a stopper, and 3N 4oM with stopper; 4m shows
5+m + 4oM (over 2H overcall this shows slam interest, else use 3S); other bids are nat
e.g.
1N-(2C)-X = neg
1N-(2D)-X-2S-3C = 5(+)-8, 5+C-4H NF
1N-(P)-P-(2D); P-(P)-X = penalty
1N-(2D)-2S = 3-7, 5+S
1N-(2H)-3C = 8+, 5+D, denies 4S, F1
1N-(2C)-3D = 8+, 5+H, F1
1N-(2D)-2N = 8+, 5+C, F1
1N-(2D)-3S = 9+, 5+C-4H, GF
1N-(2S)-3H = 8(+)+ 5+C, F to 3N/4C
1N-(2S)-4C = 6+H, slam interest, denies short S (else 4D)
1N-(2H)-4C = 6+S, slam interest, short H
1N-(2C)-4H = 6+H, no slam interest
1N-(2H)-2N-3C-
Pass/3D = 0-6, 6+m
3H = 9+, 4S, no H stopper or 5+m
3S = 4S-5+m, no slam interest, GF (slam uses 4m)
3N = 9-14, 4S, H stopper
4m = 5+m-4S, slam interest
1N-(2S)-3S = asks stopper, denies H
4. Natural 3+-level overcall
A. Double is 9+ without shortness in their suit (at 4-level it is 90% penalty). Vulnerability determines
how penalty it is.
B. General rules:
a. new suit is GF, except 3D, which is forcing to 3N/4D
b. no Texas
C. Cue-bid shows slam interest with various types of hands.
D. 4N shows 5+ 5+ minors over a 3M overcall, but is quant over a 3m overcall.
e.g.
1N-(3S)-X = optional at favorable
1N-(3H)-3S = 8+, 5+S, GF
1N-(3C)-4D = 6+D, slammish
1N-(3D)-4H = 8-11, 6+H
1N-(3H)-4H-4N = nat, denies 4S
1N-(3D)-4N = quant
1N-(3S)-4N = 5+ 5+ minors
5. Double of an artificial overcall is cards, willing to sit for partner's penalty doube, forcing to 2N. The
cue of an opponent's suit and 2N are the same as over a natural overcall.
6. Double by opener when partner passed at first opportunity:
A. At the 2-level
a. double is takeout if the suit is natural or p/c
B. At the 3-level, double is takeout with a very good hand (and higher is penalty)
7. Over an enemy double of 1N-3N, redoubles shows desire not to play 3N, while pass shows willingness or maybe
just no good alternative contract. This applies to both hands.

1. Double
A. Meanings of Pass and continuations
a. Pass accepts the contract if partner has the suit bid; pass may be strong
b. if opener does not have length in the suit opened, with equal length he runs to his next suit;
if the non-cheapest suit is longer he redoubles, and when the cheapest suit is longer, he bids it
if below 2N, and bids 2N if it is above 2N.
c. in all further bidding, doubles are penalty
B. XX = penalty, 15+ and 5+crds in the opened suit
C. Other bids are the same as if no interference
e.g.
2S-(X)-P-(P); 2N = 6+D-5H (closest suit longer)
2H-(X)-P-(P); XX = 6+D-5S (further suit is longer)
2H-(X)-P-(P); 2S = 5+S-5+D, S not shorter than D (else XX)
2H-(X)-P-(2S); X = penalty, max opening
2S-(X)-XX = 15+, 5+S, penalty
2S-(X)-3C = p/c
2. Overcall
A. Double
a. double is penalty, natural or "sure" partner has the suit
B. New suit and continuations
a. a new suit is NF, if it is not one of opener's suits it is invite
b. if opener has 5+ in the opponent's suit, then over partner's bid it is better to keep bidding
in case partner has wrongly guessed which two suits opener had
c. if responder knows that opener has length in the opponents' suit but wants to play in his other suit
he can bid the cheapest bid that opener could have, as p/c
C. Cue-bid at 3-level is asking for a half-stopper
D. Later bids
a. Double = takeout with extra strength
b. All other bids show 6+-5+ distribution
E.g.
2H-(2S)-X = penalty - someone has length in the suit
2S-(3C)-3S = 6+S, invite
2S-(3C)-3H = p/c, NF
2H-(3C)-3S-3N = 5+ 5+ H-C
2H-(2S)-3S = asks for half-stopper
2H-(2S)-P-(P); 2N = 6+H-5+C (further suit longer)
2S-(3C)-P-(P); X = takeout, extra strength

*************************
I. General Principles
*************************
*************************
1. En Passant and NT Probe
a. Bidding 4th suit or the opponents' suit (asking for stopper). Over an enemy double
i) rebidding a previously-bid suit shows extra shape
ii) pass = 2+crds without a full stopper, over which XX by partner shows a half-stopper
iii) XX = shows stopper, suggests partner declare NT
iv) 3N = stopper, better declared by that side
b. En Passant shows a stopper in the bid suit, suggesting worry about other suit(s). En Passant only involves
suits that cannot be trumps. Over a double of an en passant stopper-showing bid:
i) pass = no stopper in the 4th suit, over which XX by partner shows a good stopper, but not to play.
ii) XX = shows stopper in 4th suit and worry about the X'd en passant suit (no help)
iii) 3N = stopper in 4th suit and no worry about the en passant suit
2. 5-4 Convention
a. After showing 5+-4+ distribution, when partner sets the M at the 3-level (and after 1C-2C/N and 1D-2D/N),
the next bid is according to the following rules:
i) shortness is shown naturally, even in partner's suit
ii) bidding NT shows 5422 shape
iii) rebidding the 2nd suit shows a decent suit with at least one extra card in length, unless
the bidding makes that impossible, in which case it shows 5422 with concentration in the
two suits; showing extra distribution is not obligatory and instead shortness may be shown.
iv) rebidding trumps shows an exceptionally bad hand
e.g.
1C[H]-1H[S]-3C[nat]-3H[sets H]-3S = short S
1H[C]-1N[nat]-2S[rev]-3S[sets S]-3N = 4225
1D[S]-1S[art GF]-2S[H]-3H[sets H]-4D = short D
1C[H]-1H[S]-3D[nat 5-5]-3H[sets H]-4D = 5+H-6+D, suggests 5161
1D[S]-1S[art GF]-2S[H]-3H[sets H]-3S = 5422, conc. in the long suits (6crds impossible)
1D[S]-2C[5+H]-2D[art GF]-3C[D]-3H[sets H]-4H = totally minimum hand
3. Scheme over a strong 2N where a M is known, or known to have no M
a. This applies over 1m-neg-2N, 1m-neg-2C-2D-2N, and 2D-2M-2N (not 2N opening since may or may not have M).
b. Continuations by responder have the following meanings:
i) 3C = 6(5)+D, 0+ HCP, over which bidding a suit after the transfer, even in opener's suit,
shows shortness, with 3N as light slam invite and 4D serious slam invite
ii) 3D = 3+H over 1C opening, or 5+H over 1D/2D opening - continuations analagous to over a strong
2N opening and transfer response
iii) 3H = 3+S over 1D opening, or 5+S over 1C/2D opening - cont's same as over 2N opening and xfer
iv) 3S = 4+ 4+ minors, GF, same as after a 2N opening
v) 4C = 6+C, no side shortness, slam interest (4N = neg, else cue for C)
vi) 4D/M = short D/M, 6+C, slam interest (4N = neg, else cue for C)
c. If the bidding is GF, then accepting one of the transfers (3C/3D/3H) shows a fit
e.g. 1C[H]-1D[neg]-2C[F]-2D[neg]-2N[GF bal]-3D[3+H]-3H[confirms 5H fit]
4. Forcing Shape Relay
a. Over the sequences:
1C-1D-1S/2m/2S
1D-1H-2m/2H
1D-2C-2M
1M-1N-2M
1C-1H-2C-2D-2H
.... 2NT is a GF relay for shape if responder is not a passed hand (even BPH if opener has set a GF).
If 2N is not an ask, then it is natural. Included also is the 2S bid after 1C-1H-2D, as a GF ask.
b. Opener responds naturally and economically:
i) 3+crds in a previously unshown suit if possible (else this would show 5422 with extras)
ii) 4+crds in a side suit if still possible
iii) one of opener's suits, if extra length (when impossible, this is 5422 with extras)
iv) 3 of a new suit, which is a 4crd suit, completing the description
v) 3N and 4N showing distributions not covered by i/ii/iii/iv
e.g.
1C[H]-1D[wait]-2D[good hand, nat]-2N[GF relay]
3C = 17-21, 1543/0643/0553 (a 3-crd suit)
3D = 16-18, 5+H-5+D, denies 3C
3H = 16-21, 6+H-4D, denies 3C
3S = 17-21, 3541 (a 3-crd suit, denying other types)
3N = 17-21, 2542 (only remaining possible type)
1D[S]-2C[5+H]-2S[no fit NF]-2N[GF shape ask]-
3m = 11-13, 5+S-4m, short H
3H = 11-12, 62(32), pretty good S (cannot have 3crds since 2S denied fit)
3S = 11-12, 6133 (denies 4m or 2H)
c. In the sequences
1C-1H-2D-2S
1D-2C-2H-2N
... responses are according to the transfer scheme:
i) bidding a suit shows extra length in the next-higher suit
ii) 3N (and even 3S over 2S to deny at least a half-stop in clubs) shows the most balanced possible type
iii) other bids show 3/4 crds in the suit, which may agree the most likely, but if it cannot be this
then it is limited to a natural meaning
e.g.
1C[H]-1H[S]-2D[nat]-2S[GF relay]-
2N = 11-16, 4H-5+D
3C = 11-16, 5+H-5+D (xfer to D)
3D = 11-16, 6+H-4D (xfer to H)
3H = 11-16, 1543 (xfer to impossible suit)
3S = 11-16, 2542, not even half-stop in C
3N = 11-16, 2542, at least half-stop in C
1D[S]-2C[5+H]-2H[min, to play]-2N[GF relay]-
3C = 5+-4+ S-C either way, 2H (C and not D, following natural criteria)
3D = 4+S-3H, no shortness
3H = 6+S-2H, suggests not having 4+C
3S = 5S-2H-4+D or 4S-2H-5+D
3N = 5233/4234/4243
d. In using the transfer scheme, if showing 5+crds in the lower suit (5+-5+), then opener to the next relay
shows shortness up the line (l/h) in the order: sing/sing/void/void, except 3N is bypassed, reserved
to show a stiff K/Q and not too much extras.
e.g.
1C[H]-1H[S]-2D[nat]-2S[GF relay]-3C[5+5+]-3D[relay]-
3H = sing. C (lo short)
3S = sing. S (hi short)
3N = 11-14, 2551/1552, stiff K/Q (minimum, stiff honor)
4C = void C (lo void, wrapping around 3N)
4D = void S (hi void)
5. Relay Scheme
a. The relay scheme applies after
1m-1S [GF relay]
1H-1S-2C-2D [art F1]
1S-2C [art F1]
1N-2D-2D/H/S-3C [GF re-stayman]
2C-2D [asks longer M]
Shortness is usually shown up the line (l/m/h). Shapely hands are shown in steps.
b. At the end of shape-showing (not having further relays or the shape is completely defined after a 1N opening)
and GF shown by responder a suit without a jump below 4D (4D without a jump is an end-signal, forcing opener
to bid 4H and then pass whatever responder bids next, except that 4N or 5H...5N are quant invites) is a strong
bid setting the suit and asking for cue-bids. Setting the suit is done in long-to-short order. If suits are
equal length or unknown length, the default order is H-S-C-D. Signing off in game is not used over 1m-1S if
opener shows 14+ HCP (unlimited), and therefore 4D is used as a possible suit-agreeing step in the above scheme.
e.g.
1N-2C[stay]-2S-3C[restay]-3D[4D]-
3H = asks doubleton (cares which)
3S = art sets first trump suit in queue: longest first - here equal length suits (S=D), so S first
3N = to play
4C = art, sets second suit in queue: sets D
4D = end-signal, forces 4H to pass/correct to final contract (except 4N, 5H+ = quant)
4H = art, sets third suit in queue, here H before C since relative length unknown
4S = art, sets last suit (C)
after artif. setting suit, start cuebidding for that suit
1S[D]-2C[F]-2H[3H]-2N[GF relay]-3D[2353/3343/3352]-3H[R]-3S[2353]-
3N = to play
4C = sets first suit in queue = longest = D
4D = end-signal, prepares signoff
4H = sets second suit in queue = next-longest (H or C), since equal, H first
4S = sets third suit = C
c. The 5-4 scheme is used over 1m-1S, if opener shows 5 in one of his suits and 4 in the other. The first step
in the proceeding relays shows shortness in the lower side suit, 2nd step shortness in higher side suit, third
step showin 5422.
e.g.
1C[H]-1S[R]-2C[5+H]-2D[R]-2S[5H-4other]-2N[R]-3C[5H-4C]-3D[R]-
3H = lo side short (3514)
3S = hi side short (1534)
3N = 2524
d. The 6-4 scheme is used over 1m-1S and 1H-1S-2C-2D, if opener shows 6+ in one suit and 4 in the other. The
first step to the following relay shows shortness in the lower side suit, second step shortness in higher.
e.g.
1H[C]-1S[wait]-2C[5+C no 4M]-2D[R]-3D[6+C-4D]-3H[R]-
3S = lo side short (short H)
3N = hi side short (short S)
e. The 5+-4 scheme is used after 1m-1S, if opener shows 5+crds in one suit and 4 in the other. The first step to
the following relay shows 6+crds in the primary suit, and others are run-on to the 5-4 scheme steps. After
showing 6+crds, the next relay follows the 6-4 scheme.
e.g.
1D[S]-1S[R]-1N[4S or 5332]-2C[R]-2D[4S-5+m]-2H[R]-2N[4S-5+D]-3C[R]-
3D = 6+D-4S (relay follows 6+-4 scheme)
3H = 5D-4S, lo side short (4351/4450)
3S = 5D-4S, hi side short (4153/4054)
3N = 5D-4S-2-2
f. The 6+ scheme is used after 1m-1S, if opener shows 6 or 6+crd 1-suiter. Over the following relay, shortness
is bid l/m/h, and the 4th step shows no shortnesss.
e.g.
1C[H]-1S[R]-2C[5+H not 5332]-2D[R]-2H[6+H or 6+-4]-2S[R]-2N[6H 1-suiter]-3C[R]-
3D = 3631 (low side short)
3H = 3613 (mid side short)
3S = 1633 (hi side short)
3N = 6H-(322) (no side short)
*************************
*************************
II. Slam Bidding
*************************
*************************
1. SLAMTRIES
a. A simple slam invite is setting trumps below game when it is not used as a choice of games. This shows extra
strength, forcing partner to cue-bid, unless he has the worst possible hand. Setting trumps below game is
a direct slamtry in the following situations:
i) a gameforce has already been set
ii) 1D-2C-2N/3m-4m
e.g.
1C[H]-1H[S]-3D[GF 5-5]-4D
1D[S]-2C[H]-3C[4S-5+C 11-13]-4C
the following are invites, and NOT direct slamtries:
1C[H]-1D[wait]-3C[5-5 strong but NF]-4C (GF had not been set)
1S[D]-2H[H flexible]-4D (GF had not been set)
b. A descriptive slamtry is a slow and non-forcing suit agreement, in a gameforcing situation, after first showing
2 suits naturally. This shows extra strength, shortness in the 4th suit, and agrees trumps. If a splinter had
been available, then this route shows just 3-crd support.
e.g.
1D[S]-2C[H]-2S[min misfit]-3C[nat GF]-3N-4S = extras, short D, 3S-5+H-4+C, slam invite but NF.
c. Directly bidding game without stopping to set trumps more cheaply shows the worst possible hand for the
auction to day or minimal chance of a good play at slam. With anything else it is better to make a simple slam
try or cue-bid.
2. CUE-BIDS
a. Honor cue-bids are bid cheaply up the line, while shortness (if not a splinter) is better shown on the first
pass when:
i) the hand has already shown a 2-suiter
ii) the short suit bypasses 2 cue-bids, without which the slamtry would be highly improbable
iii) trumps is a minor, the auction has not reached 4m, and showing the shortness goes past 4m
Don't use shortness-showing in the early auction. Rebidding shortness shows a void, or a singleton Ace. The
first cue-bid in partner's suit may be shortness.
e.g.
1C[H]-1S[R]-2S[14+, 4S]-3C[6+C 1-suiter]-3N-4D = short D, crossing the 4C level
1N-2D[xfer]-2H-3D[D GF]-3N-4C = short C (2-suiter bidding side suit)
1D[S]-1N-2H[C or GF 1suiter]-3C[nat]-3S[1-suiter GF]-3N-4H = short H (bypassing 2 cue-bids improbably)
b. A critical cue-bid is one that is interpreted initially as en passant or stopper-asking, and only on the
following bid the cue-bid character of the first is revealed.
e.g.
1S[D]-2C[R]-2D[art GF]-3D[nat]-3S[initially en passant no H stopper]-3N[H stop]-4C = S and C cues
c. In murky situations, 4m is a natural bid and not a cue-bid if the previous auction showed a 6+crd minor, and
partner has not promised a 6+ suit of his own.
e.g.
1H[C]-1S[wait]-3C[inv]-3H[5+crds]-4C = natural (3H may be just 5crds)
3. SPLINTERS
a. The sequences:
1C-3N/4m
1D-4m/4H
... show 12-15(-) and a 5+cd fit with shortness in the bid suit (3N = short S). 1H-3D/3M has the same
meaning, except that it shows a 4+crd fit. Splinters (showing shortness) are used in more auctions (and over
other openings) and appears as a jump-shift, which cannot be a natural bid in the system. A splinter promises
enough honor strength for game, usually 4+ support for the agreed suit or the last-bid suit, as well as slam
interest.
e.g.
1H-3S
1C-3N
1D[S]-2C[H]-2S[no fit]-4C
1H[C]-2D[H]-3S
1C[H]-1H[S]-4C
b. A special type of splinter is the autosplinter, used over a NT bid (or opening) or negative. Shortness is
shown with a jump, showing a decent 6+crd trump suit, if partner has promised 2+crds (else it must have at
least 3 honors), and extras.
e.g.
1D[S]-1H[wait]-4D = 19+, self-sufficient 7+S, short D
1N-2D-2H-3S = 9+, 6+H, short S
1C[H]-1H[S]-1N[nat]-4C = 12+, 6+S, short C
1H[C]-1N[nat]-3D = 17+, 6+C, short D
c. Over a 1N opening and superaccept by raising the transfer, 3N here is forcing and shows no shortness, or
shortness in the retransfer suit. However, when a retransfer is not needed, then this ambuiguity is not
needed.
e.g.
1N-2H-3H-3N = 10+, 5+S, no shortness or short H, slam interest
1N-2D-3H-4D = 10+, 5+H, short D, slam interest
d. Splinters offer some specialized continuations. Raising the splinter shows nothing wasted in the suit usually
without a side cue-bid. Bidding 5M when M is trumps usually shows the Ace of the splinter suit and no side
cue-bid. Bidding 3N over 1H-3D/M suggests playing there.
e.g.
1C[H]-2D[good raise]-4D[spl]-5D = nothing in D, no side cue-bid
1D[S]-4C[spl]-5S = Ace of clubs, no sie cue-bid
1H[C]-3H[spl]-3N = suggests playing 3N
4. SPECIAL SLAM-INVITES
a. Bidding a suit at the 6-level, if not to play, or at the 5-level above the level of trumps after a Blackwood
response, is not asking but is an invite to grand slam, which depends on unrevealed values in the bid suit. If
the invite suit is one in which partner has shown shortness, it asks for a void.
e.g.
1H[C]-2C[F raise]-4N[BW]-5C-5S = invites grand opposite help in S
1D[S]-2N[good raise]-3D[nat]-3S-4C-4N-5S-6D = invites grand opposite help in D
1C[H]-4C[spl]-6C = asks for void C
b. Quantitative NT is a power invite and depends on strength. A 4N bid is invite and not Blackwood, in the
following situations:
i) the last bid was a natural 3N or a 1N/2N opening; if partner of the inviter has an in-between hand,
then he bids a conc. of values at the 5-level as a counter-invite
ii) the last bid was a suit at the 3-level and no suit has been set, or a minor has been agreed;
removing 4N to the agreed trumps suit or bidding a potential trump suit of ones own is signoff.
e.g.
1H[C]-2C[F raise]-2N-3N-4N[quant]-5C[extras, good C]-5N = signoff
1N-4N[quant]-5N = extras, suggests evenly-distributed honors
2N-4N[quant]-5H[counter-invite conc.]-6C = suggests contract
1D[S]-2C[H]-2N[4144 min]-4N = quant
1C[H]-1H[S]-2S[17+ various]-3S-4N[quant]-5S = to play
1H[C]-2C[F raise]-3C[signoff bal]-4N = quant (minor agreed)
1S[D]-2C[R]-3D[6+D]-4N = quant (no suit set)
2H[multi]-2N[ask]-3D[min D-S]-4N = quant (no suit set)
1C[H]-1S[R]-3D[great 1-suiter]-4N = quant (no suit set)
c. If 4N would have been a natural invite and the last bid was NT, or if a grand slam force is nonsensical,
then a 5N bid forces to slam and shows difficulty in choosing the right strain. Continuations are natural
and show a preference for the bid contract.
e.g.
1D[S]-2C[H]-2S[no fit]-5N[pick]-6S = 6+S, suggests contract
1S[D]-2C[R]-2D[GF]-3C[nat]-3D-3N-5N[pick]-6C[pref for C]-6N = signoff, was evidently a 6D/6N choice
1N-5N[pick]-6D = decent 4D or 5-6D, suggests contract
d. Another slam invite is naturally bidding the agreed suit at the 5-level if trumps is a major. It has two
possible meanings: a trump invite showing good side values but asking for good trumps, or an inverted trump
invite, showing very good trumps and no possible cue-bid. Usually the trump invite hands start with cue-bidding,
and the inverted trump invites set trumps below game first. Which version of the invite the bid depends on the
development of the auction.
e.g.
1D[S]-2C[H]-2D[14+ GF]-2H[6+H]-3C[nat]-3H-3N-5H = reverse trump invite
1D[S]-2H[simple raise]-5S = trump invite
5. ASKING FOR KEYCARDS
a. The ask can be 4NT (whether trumps have been set explicitly or implicitly, it is then asking for the 4 Aces
and the King of trumps) as well as a special exclusion Blackwood (see [b]). 4N is asking, if after cue-bids
or when it cannot be natural (as an invite), and otherwise when asking makes sense (see [d]).
e.g.
1H[C]-2D[H]-4N
1N-2C-2H-4C[spl]-4N
* Not Blackwood:
1N-2C-2D-4N
b. Bids at the 4 or 5 level are exclusion Blackwood if it is bid as a jump below the level of trumps at the 5
level, and bids at a lower level would show shortness. An exception to this rule is a 4M bid, which without
exclusion Blackwood would be natural. On defense, exclusion Blackwood may be only bid at the 5-level.
Exclusion Blackwood asks for keycards outside of the bid suit, and promises 1st-round control of the bid suit.
e.g.
1H[C]-4D
1D[S]-2C[H]-2H[to play]-5C
1N-2C-2S-5C
1C[H]-5D
* Not Exclusion Blackwood
1D[S]-2D[good raise]-3D[nat slammish]-5C (4C would not be showing shortness, so this must be shortness)
1H[C]-2S[simple raise]-5D (5D is higher than 5 of the trump suit)
1C[H]-4S = nat
(1C)-1H-4S = nat (even though 3S = splinter)
c. Step responses:
1: 1 or 4 keycards (over Exclusion BW, shows 0 keycards)
2: 0 or 3 keycards (over Exclusion BW, shows 1 keycard)
3: 2 or 5 keycards, no Queen of trumps (over Exclusion, shows 2 keycards)
4: 2 or 5 keycards, Queen of trumps, no side King (over Exclusion, shows 3 keycards)
5: 2 or 5 keycards, Queen of trumps, 1 side King (over Exclusion, shows 4 keycards)
6: 2 or 5 keycards, Queen of trumps, 2 side Kings
7: 2 or 5 keycards, Queen of trumps, 3 side Kings
Further bids at the 6-level are showing 2 keycards and a void (it is not obligatory to show a void,
especially if the hand has already shown shortness).
d. Over Blackwood (even Exclusion), the ask for the trump Queen is the next non-trump step (going back to trumps
is a signoff). Responses are in steps, with the first showing no Queen, and others the Queen (or enough trumps
to make the Queen unnecessary) according to number of Kings by steps (0, 1, 2, 3) but not including the King
of trumps (already considered earlier as a keycard). The ask for number of Kings instead of the Queen is the
next-cheapest non-trump step, and resposnes are 0, 1, 2, 3 Kings.
e.g.
Queen-asks:
1D[S]-4N-5D[0/3]-5H
1H[C]-4D[excl]-4S[1 keycard outside D]-4N
1N-2C-2S-5D[excl]-5S[1 keycard outside D]-5N
Asks for # Kings:
1C[H]-4N-5H[2KC no Q]-5S
1D[S]-2D[good S raise]-4N-5C[1/4]-5H (5D would have asked Queen)
1N-2C-2H-4S[excl]-5C[1 KC outside S]-5S (5D would have asked Queen)
e. Bidding 5N over normal Blackwood and a 5m response when a minor is trumps is to play, denying
enough KC's for slam.
e.g.
1S[D]-4N-5D[0/3]-5N = to play (5H would ask Q, 5S would ask # Kings)
1H[C]-4N-5H[2KC no Q]-5N = invites grand slam (did not get a 5m response) (5S would ask # Kings)
f. Bidding 5N before setting trumps without using Blackwood or when the last bid suit is a natural suit
(and grand slam force makes no sense) is asking for top honors in the suit. Step responses are 0, 1, 2, 3
top honors in the trumps suit.
e.g.
1C[H]-1S[R]-2D[14+ 5+H]-5N-6D = 1 top H honor
4S-5N-6S = AKQ spades
g. 4N is natural (quant 4N was discussed elsewhere), when the auction meets the following conditions:
i) strength is limited and had earlier indicated interest in playing NT - this condition is not possible
if partner has shown an Acol (22+ 5+crds)
ii) nobody has taken control of the auction (usually partner is weak)
iii) nobody has set trumps (not possible if partner has shown an Acol)
Given the flexible interpretation of these conditions it's best to use the natural 4N only when it is clear.
e.g.
1S[D]-2C[R]-3C[nat min]-3N-4C-4N = to play
1C[H]-1D[wait]-2S[GF M's]-3C[nat]-3S-4D-4S-4N = not clearly nat 4N, but shows extras and no cue, for S
1H[C]-1N[nat]-3S[GF autosplinter]-3N-4C-4N = to play
1H[C]-2C[F raise]-3H[14+ weak doub bal]-3N-4C-4N = to play

III. Opener's Rebids in Competition
***********************************
***********************************
A. After an overcall by LHO (2nd seat), and both partner and RHO (4th seat) pass.
1. Keeping the bidding open
a. at the 1-level, reopening is obligatory unless unfavorable vul or holding length/strength in
their suit
b. at the 2-level, reopening is mandatory at favorable vul without strength/length in opp suit
c. if reopening is not mandatory, then doing so shows extras in strength or distribution
d. double is takeout-oriented
2. After an overcall at the 1 or 2 level
a. A reverse shows 18-21 and an offensive hand, but if preceded by a double, it shows 16-21 but not
an offensive max.
b. NT bids are 19+, based on tricks.
c. Showing a suit at the 2-level below the opening suit shows 5+ or a v. good 4 cards.
d. Over 2D/2H/2S, 2N is special (Leb) showing 5+crds in a lower suit, or even 6+ in the opened suit
if the overcall was a cue or higher with max 17 HCP (min is vul-dependent) or any GF unsuited
for any other bid; partner must bid 3C (unless was trap-passing), over which opener passes C
or shows his suit with max 17,or with a GF bids the opponent's suit or a 4-level bid
e. Over 2D/2H/2S, directly bidding at the 3-level below the overcall suit shows 5+crds, 17(+)-21, while
rebidding the opened suit at the 3-level over a jump overcall is invitational.
f. A new suit at the 4-level shows 6+crds, GF
g. Cue-bidding the opponent's suit is GF, an auto-splinter if a jump.
3. After an overcall at the 3-level or higher.
a. At the 3-level, a double is a strong takeout with tolerance for a pass; vul-dependent
b. At the 4-level or higher, double is just cards.
e.g.
1S-(2C)-P-(P); 2S = 18-21, 4S-5+D, offensive hand
1H-(2D)-P-(P); X-2H-2S = 17-21, 4S-5+C, not max if offensive
1C-(2C)-P-(P); X-2D-2S = 19-21, 4S-5H, suggests defensive hand
1D-(2D)-P-(P); 3H = 17-21, 5+S-5+H
1C-(2S)-P-(P); 2N = max 17, or GF; 5+H-5+m or 6+H
1D-(2H)-P-(P); 2N-3C-3D = max 17 4S-5+D
1C-(2S)-P-(P); 2N-3C-4D = 5+H-5D GF (with 6+D bid 4D immediately)
1D-(2S)-P-(P); 4C = 5+H-6+C GF
1S-(2H)-P-(P); 3C = 17(+)-21, 5+D-5+C
1C-(2C)-P-(P); 2N = 5(4)+H, 8 tricks in NT
1H-(1N)-P-(P); X = 19+
1C-(3S)-P-(P); X = strong takeout but passable
4. Responder's bids with a trap-pass and rebid by 2nd seat:
a. Over 2nd seat's XX, pass is to play showing a trap-pass. Other bids are as normal over pd's double.
b. Over 2nd seat's new suit bid, double is cards and shows the original trap-pass.
c. Over 2nd seat's same suit rebid, double is penalty.
5. Bidding over 2nd seat's pass, responder's negative, and 4th seat's bid.
a. Best is to bid as over 1m-(bid)-P-P, but double promises 16+.
B. Double by opener when both opponents bid and partner passes or makes a negative.
1. Over an artificial bid by 4th seat:
a. double is natural, showing extra length if RHO's bid was forcing
b. double is takeout, if RHO's bid was NF (p/c, e.g.) below 3N (if higher, then penalty)
c. double of NT is cards
2. Over a natural bid by 4th seat;
a. double is takeout below 4 of the original suit
b. in further bidding, if responder had passed originally, then removing opener's double to a 2-level
suit is to play at the 2-level, invitational at the 3-level; however double of an opponent
at the 2-level is takeout, and optional at the 3-level
C. Opener's Rebids over a transfer response over LHO's overcall:
1. Over a transfer to 1S: 1C-(1D)-1H (showing spades)
a. completing the transfer at the 1-level is F1, unlimited, showing 3S, or a GF bal with 4S
b. jump-accepting the transfer at the 2-level is a simple raise, 4 cards
c. cue-bidding the opponent's suit is GF, denies 3+S
d. other bids have the same meaning as if no interference (1C-1H)
2. Over a transfer to 1N
a. opener's rebid is just as over a natural 1N response
b. over a 1N reid, responder's delayed simple raise shows an invite without a stopper, usually
a doubleton in support, and opener's rebids are nat NF
c. over a 1N rebid, a delayed cue-bid at the 2-level shows 13+/11+ forcing to game or 4m (except
a later raise of opener's 2-suit rebid to the 3-level, which denies a stopper), denying
a stopper and denying slam interest
d. over a 1N rebid, bidding a 2m new suit is nat NF
e. bidding 3C over a weak rebid (not 2C), shows 5+C (if a jump 6+), GF
e.g.
1C-(1S)-X-2N = 16-17, invite
1D-(1H)-1S-1N-2S = 11-12, 2S, invite, no H stop
1C-(1S)-X-1N-2S-2N = 11-15, S stopper, forcing
1D-(1H)-1S-1N-2H-2S-3S = 12(+)-13, 2S, no H stop, invite
1C-(1S)-X-2D-3C = 5+C, GF
3. Over a 7+ HCP transfer to a new suit at the 2-level
a. Completing the transfer is to play opposite an average transfer hand, further bidding is natural,
Responder's bids: returning to opener's suit at the 2-level is NF with a weak 3crds, and at the
3-level is invite wwith a pretty good 3crds and a good transfer suit; a new minor is F1, a
new major is GF, cue-bidding at the 2-level is F1, and at the 3/4 level GF
b. 2-level reverse is F1
c. New suit non-reverse at the 2-level is NF, and at the 3-level withut a jump invite with 5+crds
(if jump to 3-level, GF 5-5)
d. NT, rebidding the opened suit, or raising responder is natural with higher = better
e. Cue-biding is GF (or to 4m if the transfer was to a minor)
e.g.
1C-(1S)-2C-2D-2H = 7-9, 5+D weak 3H, NF
1D-(1H)-1N-2C-3S = 10-11, 5+C, good 3S, invite
1D-(1H)-1N-2C-2N = 10-11, 5C, H stop, invite
1C-(1S)-2C-2D-2S = 10+, 5+D, F1
1C-(1D)-1N-2C-2S = 12+, 5+C-4S, F to game or 4m
1D-(2C)-2D-2H-3D = 11+, 5+H-4+D, F1
1C-(1D)-1N-2S = 5+H-4S, F1
1C-(1S)-2C-3C = 4+H-5+C, invite
1C-(1S)-2C-2N = invite
1C-(1S)-2C-2S = F to game or 4D
1D-(1H)-1N-3S = invite
1C-(1S)-2C-4D = distributional invite
1C-(1S)-2C-4C = 5+H-5+C GF
4. Over a 1-level transfer raise showing exactly 3crd support:
a. Accepting the transfer at the 1-level is NF, 11-13 HCP, with low-offense 5crds or 4crds without a
stopper - later new suit by responder is F1, even a cue
b. 1N is natural, 11-14/14-16 with a stopper and 4(5) crds in the opened suit; responder's rebids of
2m are NF and the opponent's suit GF
c. Jump-accepting the transfer at the 2/3 level is preemptive, 11-13
d. A simple new suit is natural, 4+crds, 14+ HCP (except 1S over transfer to H is 11+), F1
e. A single jump-shift to a new suit is 5+-5+, GF
f. 2N = GF, 4(5)crds in the original major, and a stopper
g. Cheap cue-bid of the opponent's suit = F1
e.g.
1C-(1D)-X-1H-2C = 10+, 5+C-3H, F1
1D-(1H)-X-1S-2H = 11+, 3S, denies 5+minor, F1
1C-(1D)-X-1N-2C = 7-11/7-9, 5+C-3H, NF
1D-(1H)-X-2S = 11-13, 5+S, pree, some distribution
1C-(1D)-X-3H = 11-13, 5+H, pree, very distributional
1C-(1D)-X-1S = 11+, 4+H-4S
1D-(1H)-X-2C = 14+, 4+S-4+C, F1
1D-(1H)-X-3D = 15+, 5+S-5+D, GF
5. Over a 2-level transfer raise showing 3crd support
a. Accepting the transfer at the 2-level is NF; later bidding, responder's new suit is F1 (including
a 2-level cue), while a 3-level cue of the opponent's suit is GF
b. 2N is nat, invite, 4(5)crds in the opened suit (NS = F1, cue GF)
c. Jump-accepting the transfer at the 3-level is 11-13, pree with some distribution
d. Simple new suit = nat, 4+crds, F1
e. 2-level cue = F1, 3-level cue = GF
e.g.
1C-(1S)-2D-2H-3C = 10+, 5+C-3H, F1
1C-(1S)-2D-2H-2S = 11+, 3S, no 5+m, F1
1D-(2D)-2H-2N-3C = 9+, 5+C-3S, F1
1D-(2C)-2H-3S = 11-13, 5+S, pree
1C-(2C)-2D-2S = 15+, 4+H-4S, F1
D. Bidding over 2nd seat interference, and responder's natural suit or 2/3 level transfer (not just 7+)
1. General rules
a. a cue-bid is GF (or to 4m if the transfer is to a minor)
b. NT is natural, acc. to strength
c. rebidding the opened suit is NF
d. raising responder's suit is invite
2. Over a 2S response
a. 3-level new suit is invit 5+crds (jump is GF)
e.g.
1C-(2D)-2S-3 = 4+H-5+C, invite
1C-(2C)-2S-4D = 5+H-5+D, GF
3. Over the transfers
a. Completing the transfer shows a minimum opener without ability to rebid orig suit, NF
b. Rebidding orig. suit without a jump shows a decent 6+crds, no fit, NF
c. Other bids are GF, except a simple bid and responder rebidding his suit (NF)
d. After transfer-completion, all responder's rebids are GF except a self-raise to 4m (invite) or later
opener returning to responder's minor (4m NF)
e. After opener rebidding his orig. suit (NF), all responder's bids are GF except returning to his
own minor at the 4level
e.g.
1D-(2H)-3C-3H-4D = NF (3H F1)
1C-(2S)-2N-3C-3D-3S-4C = F (not an immediate 4m rebid)
1D-(2D)-2N-3C-3D-4C = NF (3D = F1)
1D-(2H)-3C-3S-4D = NF
4. Over a 3-level jump-response
a. new suit is forcing
1D-(1H)-3C-3D = F1
1C-(1S)-3C-3H = NF
E. 1C-1H and 4th seat interferes
a. Over a NT overcall, double is cards, and non-reverse bids NF
b. Over a double, XX 14+ and penalty-interest, pass denies 3S, and other bids as if no interference
c. Over a 2-level suit overcall, X = non-minimum with 3S (12+ or extra dist) or GF with 4+S
d. Over a 2-level suit overcall, a non-reverse new suit = NF (but at 3-level invite 5+crds)
e. 2N over 2C is natural invite, but over others it is Lebensohl (11-13 or 17+ with a side 5+crds
or 6+crds in the opened suit); responder bids 3C with minimums (opener now passes with C or
bids his suit with weak hands, or something else naturally with 17+ hands)
f. Over a 2-level suit overcall, rebidding the opened suit without a jump at the 3-level is 14-16
(otherwise use Leb)
g. Over 3-level suit interference, new suit = F1
h. Over 3-level suit interference, X is cards
i. Double by responder in balancing position is extras with tolerance over a 2/3 level overcall,
and higher just cards.

IV. Competitive Auction in Later Rounds
***********************************
***********************************
A. OBAR double
1. If we have not shown a major fit (minor fit ok)
a. 2-level: X = optional
b. 3-level: X = suggestive
2. If we have a major fit
a. 2-level: X = optional
b. 3-level: suggestive (unless the suit directly below our suit, in which case it is art invite)
c. vulnerability determines the requiements for an optional double
e.g.
1C-(1S)-X-(2S)-X = optional
1C-(1S)-2D-(2S)-P-(P)-X = suggestive
1c-(2S)-X-(3S)-X = suggestive
1D-(1H)-X-(2H)-2S-(3H)-X = invite, suggestive depending on vulnerability
1C-(1D)-1H-(2D)-2S-(3D)-X = suggestive
B. Simple 2NT when no fit, and both opener/responder have bid.
1. By opener
a. if the opponents have raised, 2N is Lebensohl by opener if it can make sense (else natural).
2. By responder
a. 2N is Lebensohl, showing a minimum response but desire to play at the 3-level (or a GF)
b. Opener over Lebensohl rebids 3C, over which partner bids a simple suit with weakess, or with a GF
cue-bids, bids 3N, or jumps
e.g.
1D-(1H)-1S-(2H)-2N = 11-13, 4+S-5+m, or 17+ 5+-5+ S-m or 6+S
1C-(1S)-2C-(2S)-2N = 11-13 6+H or 4+H-5+C, or 17+ 6+H or 5+H-5+, denies 3+D
1D-(1H)-2C-(2H); P-(P)-2N = Leb
1C-(P)-1H-(2D); P-(P)-2N-3C-P = 7-9, 4+S-5+C
1C-(P)-1H-(2D); P-(P)-3C = 10-11, 4+S-5+C (if weaker use 2N)
C. Lebensohl by responder after an original pass/negative and strong double by opener
a. 2N by responder shows a hand with any suit or a raise too weak for the 3-level
b. Opener bids 3C automatically, unless a GF or length and trength in the opening suit
e.g.
1D-(2H)-P-(P); X-2N = Leb
1C-(1S)-P-(2S); X- (2N = Leb, 3m = 5[4]+crds denies 3+H -invite, 3H = 3+H invite)
1D-(1H)-P-(2H); X-(P)-2N-3C- (Pass = 5[4]+crds denies 3+S -weak, 3D = 5+D denies 3+S - weak)
***********************************
***********************************
V. Forcing Pass
***********************************
***********************************
1. Forcing pass when we are in the game or slam zone.
A. Definition of forcing pass
a. forcing pass shows the possibility of playing game if partner does not have defensive cards, and
suggests shortness in the opponents' suit
b. forcing pass may also show a hand with slam interest, removing partner's double later
c. partner of the forcing pass can double with a defensive hand, or bid higher with an offensive hand
d. forcing pass is also used in the slam-investigating autions on certain defined sequences
B. At unfavorable vulnerability, very aggressive stance since bids are solid
a. pass is forcing if the opening is not 3C or higher
e.g.
unfav: 2D-4H-(4S)-P = forcing (we are at game, opening was below 3C)
unfav: 1C-4H-(4S)-P = forcing
unfav: 1C-(X)-3H-(3S); 4H-(4S)-P = forcing (3H is never super-weak)
unfav: 3H-(X)-4H-(P); P-(4S)-P = NF (3H opening)
C. At equal or favorable vulnerability
a. if our game ws bid after a preemptive bid by our side, pass is not forcing
b. if game was bid after a direct bid by responder when no other raise is available, and so it may
be strong, then pass is forcing
c. over a 2D/2H/2S opening, when the immediate response was a game bid or forced, pass is not forcing
e.g.
equal: 1C-(1S)-4H-(4S)-P = not forcing (4H was pree)
equal: 1D-(2D)-4S-(5D)-P = not forcing (4S was pree)
equal: 1C-(3S)-4H-(4S)-P = forcing (4H was under pressure so could be strong)
equal: 1C-(2S)-4H-(4S)-P = not forcing (4H was pree)
equal: 2D-4H-(5C)-P = not forcing (immediate game bid)
D. After our side has promised at least invitational strength, pass is forcing, except for the following
situations when our side has not reached game:
a) when we have expressly declined the invitation
b) after 1M-2N, and the bidding is not at the 5-level
c) if the opponents bid 4M when we have set m/H
e.g.
1H-2C-(4H)-P = NF (we have set m but they bid 4M)
1C-(1S)-2S-(4S)-P = NF (we have set H but they bid 4M)
1C-2H-3H-(4C)-P = NF (we declined the invite)
1D-2D-(5C)-P = forcing (we have not declined the invite, 5-level)
1S-2N-(4S)-P = NF (1M-2N and not at 5-level)
2. At the partial level
A. Definition of forcing pass
a. pass puts the choice to partner: double the opponents, or bid higher
b. if over an enemy overcall the bidding cannot die, then the strongest sequence is passing
and then removing a double
e.g.
1C-1S-(3S)-Pass = forcing
1D-(X)-XX-(2C); Pass-X-2S = strong forcing sequence
1D-2S-(3D)-P = forcing
B. Forcing rules when it is possible to make a forcing pass
a. making a forcing pass and the removing the double is the strongest sequence, GF
b. bidding naturally without jumping is NF
c. a jump-shift or cue-bid is GF with a distributional hand
e.g.
1D-(1N)-X-(2H); 3C = 5+-4+ black suits, NF
1N-(X)-XX-(P); P-(2S)-P; X-3C = 5+C, GF (pass then remove)
1D-(X)-XX-(2D); P-X; 3S = great suit 6+crds 3 honors, slam interest (pass then remove)
1S-(1N)-X-(2C); 3D = 6+D, GF
3. Other situations
a. over a 1-level opening, 2nd seat passes, at least a semipositive response, and 4th seat jumps to
the 5-level or higher, pass is forcing
1D-(P)-1N-(5C); Pass = forcing
1C-(P)-2D-(5D); Pass = forcing

VI. Handling Doubles of Slam Conventions or Relays
***********************************************
***********************************************
1. Over double of a relay or transfer
A. Double of Stayman
a) Redouble shows pretty good 4+ clubs
b) Pass allows partner to decide, with XX as penalty, while 2D is natural forcing to 2N, and 2M
is as over 1N-2C-2D
c) With a doubleton club or bad 3 cards, it is better to respond as over no double
d) over opener's bid (not Pass/XX), further bidding is same as with the double, except that
3C later is not re-Stayman but just asks for a stopper
B. Double of 1C-1H-1S/1N-2C relay
a) XX = pretty good 4+C
b) Pass allows partner to decide, where XX is penalty, and other bids natural
c) without a good 3 clubs, it is best to respond as if no double
C. Double of a 2D/2H transfer
a) XX = pretty good 4+ crds in the suit doubled
b) Pass = denies 3+fit
c) Completion of the transfer = 3+crds
D. Double of a relay or other artificial responses to an opening 1N
a) the following rules apply when any relay over a 1-level opening and in relays following Stayman,
even 1N-2S-(X) or 1N-2D-2H-2S(X)
b) Pass shows no stopper in the doubled suit, after which XX asks to continue the normal responses
c) redouble is suggestive and shows length or values in the opponent's suit
d) other bids are without change, but show a stopper in the opponents' suit unless of course the bid
shows shortness in their suit
e) EXCEPTION: bidding at the 3-level over 1m-1S-2C-2D-(X), which it is better to show 5+5+ without
reference to a D stopper, and 3C bid shows short D and denies 5+-5+ distribution
e.g.
1C-1S-2C-2D-(X)-P = no D stopper or shortness in D, good 4+D or 5+-5+ distribution
1D-1S-2C-2D-(X)-3C = short D, denies 5+-5+ distribution
1C-1D-2H-2S-(X)-2N = short S, S stopper is impossible
1C-1S-2H-2S-(X)-P-XX = asks to continue normal responses (pd does not have stopper)
1N-2C-2H-3C-(X)-3H = 3433 or 5H, promises C stopper
1C-1S-(X)-1N = 4H or 5H332, with stopper, denies 4S
1D-1S-2D-2H-(X)-XX = pretty good 4H, 6+S
1N-2S-(X)-3C = clubs longer than D, S stopper
1N-2D-2H-2S-(X)-P-XX-2N = 14(+)-16, no S stopper, doubleton H
E. Double of a response to a relay, which is not showing shortness in the suit doubled (if it shows shortness
continue as over a double of a cue-bid)
a) XX = penalty (relayer knows more)
b) Pass asks for a stopper in the doubled suit, over which XX denies one and others are responses to
the next relay, with a stopper
e.g.
1S-2C-3S-(X)-XX = Ace of spades (3S showed shortness)
1S-2C-2S-2N-3S-(X)-Pass-XX = 3145, no S stopper
1H-1S-2C-2D-2H-(X)-P-3C = 3H-6+C, H stopper (2S/2N not defined since 2N would have been relay)
1N-2C-2H-3C-3D-(X)-3H = relay
2. Double of slam convention
A. Double of a cue-bid
a) XX shows a first-round control, or King when the cue-bid promised an honor
b) Pass asks to resolve the type of cue-bid: XX = 1st-round (if shortness was shown, it is void)
B. Double of a bid asking keycards or in the RKC-asking sequence
a) Pass shows the first step, XX = 2nd step, next suit = 3rd step, etc.
b) After the Pass/XX, the next XX/step is the next ask
C. Overall of an RKC or similar ask
a) if the overcall is within 2 steps, Pass = step 1, X = step 2, first step = step 3, etc...
b) if the overcall is higher, pass shows and odd # keycards, and double an even # (even Queen ask)
D. Double of a response to an RKC ask
a) Pass is asking and X by responder shows possession
b) Over the asking pass, XX shows control of the doubled suit, and returning to trumps (even 5N)
is negative, while other bids show extras with first round control (except when the bid
goes past trumps in which case it shows slam interest)
c) XX is a further ask, and shows 1st-round control in the doubled suit and and interest in bidding
higher
d) other bids have the same meaning as if no double
e.g.
1D-2N-4N-5C - Pass = allows definition of C control, XX = asks Queen S, 5D = cue with
no worry about C
1N-2H-3S-4C-4N-5D-(X)- Pass = asking about D control
XX = no worry about D
5H = no good D control, cuebid, extras
5S = neg
6C = C void, diamond Ace, invites grand slam
