- Gambling 3NT: all minor responses are p/c
- After 1M: 3M Mixed, 3C 3# LR, 3D 4# LR, 2M constructive, 2NT Jacoby, 2-tiered splinters, 2, non-serious 3NT, wide 2-way Drury (3-level is FJS except 3C, use 2NT as FJS for clubs), game tries (SS after 1M-2M otherwise natural)

- Checkbacks: 2-way checkbacks, 4SF, 3SF, transfers after 2NT rebid, spiral, ing/leb after reverse
- 2D opener. 54 or better in majors (either way), 5-10 (54 need to be 8-10). 2NT is asking bid. If NV, 3C min better hearts, 3D min better spades, 3H max better hearts, 3S max better spades (min min max max). If Vul, 3C 8-10 54 hearts, 3D 8-10 54 spades, 3H min 55, 3S max 55 (max max min max).
- 2C: Kokish with flip of 3CH. If they bid X is t/o and values, shortness in their suit, suit is 5+.
- 2NT: regular stayman, smolen, 3S relay to 3NT (then 4CD om, 4HS shortness)
- 2NT-3S-4om: 1st rejects (next step KC anyway), 2-5 KC.
- Weak 2s: gradient responses, poor man’s kc
- Transfer Leb / 1NT interference:
- cue/slow cue need stopper/semi stopper
- after 2C/D for majors: 2H pick, 2S clubs 2NT diamonds
- 1NT-(2NT): 3C stayman, 3DH transfers
- (3C) transfers, (3D) flip, (3H) X shows spades/3S needs stopper, (3S/4C) transfers, (4D) natural
- After opponent 1NT overcall
- 1m-(1NT): multi-landy with X penalty
- 1M-(1NT): X penalty, 2C oM w/ 2#, 2D 3# LR, 2NT 4# LR
- Multi Landy.
- 2C for majors: 2NT is LR for both (max max min min), can bid 2D then bid on with LR in one, 3HS is mixed, 3CD natural escapes. Over X: XX is pick, 2D is want to play there.
- 2D for one major: 2S generally 3+ hearts and 2+ more H than S, 2D bidder can game try from there. 2N equal in both, max max min min. 3CD natural escapes, NF constructive. After X: similar to previous bullet.
- 2HS: 3D is LR. 3M mixed. 2NT minor ask: min min max max.
- X: 2C minor, 2D major, 2HS my own, 3CD my own, 2N m ask min min max max.
- X for penalty (weak): 2C is scramble, 2DHS is natural. If they run, 1st X is t/o, then X is penalty.
- All Lebensohls (see chart) and 1H-(2S):
- Transfer Leb over 1NT interference: X negative, cue/slow cue need stopper/semi stopper, transferring skipping their suit with inv+, unusual bid is 55m GF
- Transfer Leb after 1m-(2M): cue/slow cue need stopper/semi stopper, slow 3NT shows 4#M, unusual bids are minors GF, slow unusual is 5#C and 4#M.
- 1H-(2S): 3m natural, 2NT is LR 3+ vs 1S-(2H) 3H is LR3+, 2NT is LR 4+
- Better Minor Leb (no transfers) after (2H)-X: 2NT ask for better minor, so (2H)-X-3C is 0-10, (2H)-X-3D is inv+
- Doubles: takeout, ELCD, negative, responsive, maximal (123 and out, must bid anything else or maximal to make game try), support
- Other competitive bids: Sandwich 1NT BPH
- Advancing Overcalls:
- (1x)-1M: double cue mixed, cue LR, 3M weak, 2NT bal inv (12+ - 15-), JS forcing, new suit NF
- (1x)-2Y: then new suits are forcing
- (1x)-1M-(2x): cue LR 3, 2NT 4, 3M mixed
- (1x)-1M-(2y): 2NT still 12+ to 15-, lower cue 3, higher cue 4, 3M mixed
- Michaels/Leaping (good chart in doc): (1x)-p-(1y)-2x, (1x)-p-p-2x, (1nt)-(2D)-2H, (1M)-(2NT)-3M
- Except:
- (1m)-(1NT): 2c majors, 2d bad single major (10-13), 2hs good single major (14-17)
- (1m)-(1NT)-pp: 2om is majors (other is natural), then same as above
- (2M)-3M: use leaping for 55, play this as stopper ask for 3NT (or both minors and a good hand if you bid on).
- (2D)-3D: still Michaels. So play 2D-4C as clubs and either major, 4D asks which.
- (1H)-(1S): 2H spades and either minor, 2NT both minors.
- (1C)-2C: 3CD LR for HS. 2NT for both.
- (1D)-2D: 3C weak escape, 3D is invite for hearts, use 2NT to invite in spades (or both) b/c can bid on after 3H.
- Transfer Defense to Michaels (also good chart):
- Two known unusual over unusual, One known transfers (cue or transfer cue is LR+)
- Carding: standard, coded 9Ts throughout, suit pref in trump suit
- Special Defenses:
- Flannery: X t/o for minors or 13-15 balanced. 2H more distributional t/o. 2S natural. 2NT 15-18.
- Weak 1NT: X penalty then next X t/o, after that penalty again. 2C is scramble, 2DHS natural. Also (weak 1NT)-p-(2x)-X is penalty (15+ balanced)
- Strong 1C: X for Major 1NT for minors. If we bid at 1 level, 1NT is cue, 2C is natural.
- Transfers at 1-level (e.g. 1C-1H for spades): X shows suit bid, bidding their suit is t/o.
- Slam bidding:
- 1430, 5N void even, 6x void odd.

- K asks: with one bid it, with 2 bid the one you don’t have, with 3 bid 7.
