Garozzo-duPont c. 1998-2001
notes by Daniel J. Neill
Opening Summary:
1C = 3(2)+ clubs, 12-21
1D = 4+ diamonds, 12-21
1M = 5+ crds (4+ crds 3/4 seat) 12-21
1N = 15-17, no 5M
2C = 20-24 bal, or GF 1-suiter or 5+-4 2-suiter
2D = 25+ bal, or GF 3-suiter, or GF 5-5, or exactly 9 tricks with long major
2M = 7-11 weak two (no modern crap)
2N = 5-5 minors, 7-11 or GF
3y = normal preempt
3N = 4-level minor preempt
4M = normal preempt (Namyats?)
General Style: 2/1 GF except if suit rebid (except 1S-2H).
Lots of artifical 2C/reverses in uncontested auctions.
1-level overcalls can be very light if reasonable lead-directing suit.
3rd seat at fav systemic ultra-light openings/takeout double.
Intermediate Jump Overcalls.
Vs. interference, first double often announces power, inverted doubles thereafter.
Upside-down count, std. attitude, Rusinow leads.

Contested Auctions:
Doubles:
Inverted doubles - when our side has announced the majority of the strength like with a cards-showing
double, further doubles by both sides show ideally Hx or any 3 cards.
Pass instead shows shortness or xx or 4+ cards. Partner should figure it out!
Card-showing doubles - opener's double at his first rebid opportunity after partner has responded with a
non-pass shows any 16+ hand without a primary fit. The inference is that if the card-showing double is not used,
then the bid is purely competitive. If RHO has not bid, but rather LHO, then opener's
strong hands cue-bid LHO's suit to show cards.
Support doubles - there is no support "double", but 1y-(any)-1z-(any) and 1N by opener as a free-bid is the
3-crd raise, with or without a stopper. Double instead would be a card-showing double.
Same thing when advancing a 1-level overcall or responding to a 3/4 seat 1M opener in competition.
Raises in competition:
2N (not the cue-bid) is the limit+ raise in competition, whether to an opener or overcall.
Also, opener's 2N rebid in competition is the limit+ raise of responder's suit (do not go through a
card-showing double here). Thus simple raises are all competitive/preemptive. 1M-(bid)-3N is a GF raise
while 2N is limit or slam.
Vs. Weak NT:
X = equal or better
Double by advancer announces "cards", then inverted doubles, while bids are weak.
Overcalls:
1-level overcalls can be 4-crds more often than standard, and can always be lighter than standard if the
suit is decent. Jump-overcalls are intermediate if not special 2-suiters.

Uncontested Auctions:
Cue-bidding:
Most important is to set the suit (implicitly or explicitly). In a relay auction, sometimes in GAR responder
can set a suit explicitly with a super-relay (not step 1 but step 2). But if not, then the
first non-relay step sets the minor, while running on to cues sets the major
(e.g. opener shows 5-5 S-C with a 3H bid, now 3S sets C and cues are for S). This makes sense since
there is less room for the major below game. If shape has been shown with 3S or 3N, then bidding the
minor sets the minor and the cue is for the major (e.g. 3S shows S-D, now 4D sets D and cue is for S).
Mixed cue-bidding in general. Some rules about 1st round control if cueing below game, but not sure about those.
NT in a cue-bidding sequence (if not RKC) shows a cue in the last-cued suit
(e.g. hearts trump: ...4C-4D-4N = diamond cue no S cue). Rebidding a cue confirms 1st round control,
not necessarily 2 honors.
GAR:
Since 1y-2C results in some symmetrical shape-showing, the rules for those shapes are known as GAR.
It is modified from other writeups since 1M-2C in this system might contain a constructive blob;
1M-2C-2D-2M must be a signoff attempt and not a relay. Here are the most common trees.
