Bids that Require Advance Preparation

1. 2-suiter overcalls: 1-2 = 5-5+ Majors. 1 minor-3 minor = strong Majors. over 2+ 1-2=5+-5+ Majors NF (1M) 2M=oM + d or big with c,3c=oM+c 2. ART responses to 1 opening (16+ ART): 1 = 0-7; others = ART GF: 1 = or 11-13 BAL, 1 = (suits = 5+), 1N = , 2 = , 2 = 8-10 BAL, 2 = 14+ BAL, 3 = any SOL suit, others = 8+ w/3-suiter. 3. Responses to 1 opening: 2 = 5/4 (+), less than INV, 2 = same but INV, 3 = minors less than INV. could be very light nv with lots of shape. 4,5c same with more shape 2n- invitational but due to our light opening bid style may be better than you'd expect -- up to 13 particularly opposite a 1st seat white 1d. 4. Many comp TFERS used. If to new suit, = showing that suit, or a lead-directing raise perhaps w/o 5+ cards in the transferred-to suit, 1-X-1NT = tfer to Clubs, 2 = to , etc. 5. Many ART raises used. 1 under at 3-level is normally a Mixed raise (7+-9 support value with 4+ trump). 2NT normally used as Major raise. 6. (1M) 2M oM + diamonds or big with c. (1M) 3 oM + clubs 7. when showing shape in response to an artificial inquiry may choose to show singleton honor as a doubleton 8. X of S SPL to compete, other SPL X is natural. 10. Pen P of xx except under at 1 level (or of NT) 11. In general xx of 3N to play. 11. x of art. raise lead direct if c/b as much as inv, t/o otherwise 12. some relays (step 2 to break it up)

General Bidding Style

Precision (RM style). All stated point count ranges are approximate. Often upgrade with distribution, but downgrades are possible. 1NT opening = 14-16, but 15-17 in 4th seat, or 3rd seat VUL. Will upgrade or (less frequently) downgrade. 1 = 16+ or compensating shape. Rule of thumb is that 1 ok if willing to shoot out game opposite balanced 8. 1 = 11-15 catchall but 2+'s, very rarely 5M332 or stiff honor with the shape for a 2 opening. Occasionally open 10 balanced, most likely 1st seat favorable 5-card Majors 11-15, 4 possible 3rd hand, typically less than a normal opening with a good suit. 2 = 6+ 10-15 (5 possible 3rd seat) 2 = 3-suiter short in (can be 43 in Majors either way) 10-15. Responses can be light, or passes heavy. Openings tend to be light. Preempts can be on 5 (weak 2's) or 6 (3's).5 card weak 2 possible 1st/3rd seat fav., possible other nv positions, rare but not impossible vul. General light style, and variations allowed, e.g. can open 1NT with 13 if we think it is worth 14, or 1 with stiff K of Diamonds instead of 2, or opening with less than 11 HCP with a reason to to so. 1M-2M is about 8-11 in general. With less generally 1N 1st although may choose to raise if that seems right tactically. 3rd seat openings can be very light, and might be on shorter length (4-card Major, 5-card 2C opening). most doubles takeout or extra offense; 1N often 5422 (including 5h4s) even if values very concentrated; psyches rare but not impossible. Most common 3rd seat white. Very few forcing passes (and never vulnerability based). Pass/double inversion in 1c, 2/1, strong jumps shift auctions.
