Note:..1: "CHECKBACK" Extended - nonjump bid 2/3 when either partner limited his hand by 1NT rebid or simple nonforcing rebid of his suit. (Ex.: 1-1-1NT-2 or 1-1NT-2 or 1-2-2-3) Partner of the bidder shows in order of priority: 1. Undisclosed support 2. Unbid M, if it could not be bid conveniently before 3. Show undisclosed length in minors 4. NT with stoppers 5. Rebids his suit with 6 cards. Note:..2: LEBENSOHL-FAST (after 1NT opening, 2/// by OPPTs) Responses: 2//: NF, 4+ 2NT: forces partner to bid 3. Then: Pass/suit lower than OPPT's: NF 3 of OPPT's suit: STAY, no stopper 3 in higher suit: FG, no stopper 3NT: no stopper 3x: FG, 5+, shows aslo stopper if in suit higher than OPPT's 3 in OPPT's suit: STAY, stopper 3NT: stopper DBL: PEN, 4+ in seq 1NT-2-pass-2NT: STAY, no stopper. Note:..3: 4TH SUIT FORCING After 1 over 1: F1 After 2 over 1 and/or after nonminimum (e.g. reverse) rebid FG Responses should show (in order of priority): Unbid 4card suit, Stopper, Undisclosed support, Distribution Jump responses: Double stopper, strong undislosed support, Strong distribution.

Overcaller will probably show his minor. 3M: Ask for stopper 3OM: INV 4/: P/C, PRE 5: P/C. In all further sequences when overcaller rebids his M without indicating his m, advancer's bid xm seeks overcaller's minor. Advancer's new suit = CUE, support for the previously bid suit. In COMP: 1) Opener's partner DBL: Pass = waiting, WK/INV strength RDBL = INV at least, fit for at least one suit 3/ = NAT NF Other = unchanged. 2) Opener's partner raises: DBL = at least INV, fit for at least one suit OM = COMP xm = seeks overcaller's m. 3) Opener's partner bids OM: DBL = H raise = support without H Other = unchanged. 4) Opener's partner bids m: DBL = P/C Other = unchanged.

Very big hands (good 19+) start with double and rebid 2NT (or double). Good 4441 hands with a stiff minor can start with 2. Single-suited minor hands often start with double, hoping to be able to play at the 2-level. These hands will pass a 2D ask. In COMP: If they double an artificial bid, unsolicited bids are interest in playing the suit bid. Pass is to play the artificial suit; redouble is no opinion. Mnemonic for interference: If no long suit is sure, 2NT asks. All else natural. Over 2M, 2NT is an artificial game try and 3 asks for correction to diamonds if appropriate. Note:..8: MOHAN's Defense Against Weak NT (max 15) DBL Good 14+, usually balanced 2 Both M 2 Transfer to 2 Transfer to 2 + m 2NT + m 3/ NAT 3/ NAT PRE Initial actions are sound overcalls. Advancer's Actions: . After a double, the next double is takeout, usually showing exactly two cards in their suit. In response to 2, 2 shows no or little preference. 2NT is a natural game try. Jumps are invitational. 3 is to play. 2 followed by 3 is forcing. In response to 2/, all bad hands simply accept the transfer. New suits are natural and forward-going, but not 100% forcing. 2NT is a natural game try. Jump acceptances are invitational. In response to 2, 2NT is an artificial game try, asking for size and the minor. 3 is P/C. 3 is invitational. Over 2NT, 3 is P/C, 3 is NAT INV, 3 is to play, and 3 NAT FG. Overcaller's Rebids Everything is NAT; second bids show extra strength. Transfer to M followed by m shows a four-card M + six-card m. Note:..9: "LEAPING MICHAELS" - 6+m, 4M. NF. (11-16) After 2M: 4/ = / + OM 2: 4 = + M 4 = 6 + 4 Note:..10: 1NT overcall - Advancer's actions 2 = STAY, followed by 2NT or raise INV; other: to pass other non-jump = NAT INV NF jumps = NAT FG. Note:..11: 1NT opening - bidding after 2 RESP Responder's: cheapest suit = relay. other bid on the 2-level = NAT NF. 2NT = INV. 3m = 5+, S/S in Om. 3M = 4, S/S in OM. Relay bidding: (1NT-2) 2 = No M. After 2: 2 = 3 cards. After 2NT: 3 = 5 cards - 3(R) - 3/ = 3235/3325 3/ = 3253/3352 3 = 3244 2NT = BAL - 3(R) - 3/ = 3334/3343 3/ = 2335/2353 3 = 2344. 2 = 4 cards.

After opener shows the exact distribution responder: 3NT = to play 4 = PUP to 4. Responder then places the contract. other = ask for 5 key cards (1st step asks in the longest suit, 2nd in the 2nd longest etc. From the suits with equal length the lower one has priority). Then: 1st step = 0/3, 2nd step 1/4, 3rd step 2/5 W/O Q, 4th step 2/5 with Q Then: suit repeat: to play. cheapest suit = ask for kings (0/3,1/4,2), then cheapest ask for Q next cheapest = ask for Q (with 0/3 or 1/4 key cards) other = ask for H in the suit asked (Q/AK, K/AQ, A/KQ, AKQ/-). Note:..12: 1NT opening: bidding after 2 response (TRF to m) Opener: 2NT = normal hand 3 = good support for 3 = MAX, good support (A/K)xxx for both m. Then responder: P/C to m, 3/ = S/S, 3NT = to play, JMP in M = S/S, STR. In COMP: 1NT-Pass-2-DBL: RDBL = DBL stopper. Partner: 2NT = 5-5 in m, other NAT. Pass = No stopper. Partner bids as above. 2NT = stopper W/O good support. 3/ = stopper, good support for /+. DBL of S/S: RDBL = DBL stopper 3NT = stopper other = no stopper, NAT. Note:..13: 1NT opening: bidding after 3-level responses (FG) 3M = S/S, 5+4+ in m. Then opener: 3NT = good stopper (min. Kxx) 3/ = good suit 4 = not shorter than 4 = longer than 4 in partner's S/S = Ax(xx) 4 after 3 = good suit. 3m = S/S, 44(41). Note:..14: Responses to BLACKWOOD 1st step = 0/3, 2nd step 1/4, 3rd step 2/5 W/O Q, 4th step 2/5 with Q Then: trump suit repeat: to play. cheapest suit = ask for kings (0/3,1/4,2), then cheapest ask for Q next cheapest = ask for Q (with 0/3 or 1/4 key cards) Note:..15: Development after 2NT - 3 Opener: 3 = at least one M.
