An unpopular treatment. =============================================================================================================== Note:..26:"NT RESPONSES-CHANGE" This scheme is used after opnent's oppening and NT overcall. It covers several alernatives according a knowledge of oponent's suit and its majority Alternative 1: Oponent's suit is m or is unknown (for e. preparred 1 etc.) The scheme [9] for standard 1NT oppening is used but 2 doesn't cover alternative w/ lengt in oponent's suit. Alternative 2: Oponent's suit is 2: Weak 2: Weak 2: TRF to 2: Just 4 3: Both m Alternative 3: Oponent's suit is 2: Weak 2: TRF to 2: Just 4 2: Weak 3: Both m =============================================================================================================== Note:..27:"TWO SUITERS" This convention is used after 1x oponent's openning (also in Reopen position). It shows TwoSuiter hand (at least 5+5+)wi. Two bids (CUE and 2NT) are used to show such hand. CUE has below described meaning only if 1x is natural (at least 3card) oppening. 2NT has its meaning always. If 1x oppening promisses some other suit then opennig alternatives are used for promissed suit. Next alternatives describe all possibilities Alternative 1: 1m Oppening Natural CUE: 5+Om 5+M 2NT: 5+M 5+M Alternative 2: 1m Oppening NOT Natural CUE: NO Meaning 2NT: 5+M 5+M Alternative 3: 1M Oppening Natural CUE: 5+OM 5+m 2NT: 5+m 5+m Alternative 4: 1M Oppening NOT Natural CUE: NO Meaning 2NT: 5+m 5+m =============================================================================================================== Note:..28: "WOOLSEY" This scheme is used against Strong NT (from 15) openning Double = 5-card minor and a 4-card major Responses:2 = P/C.

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:..29: "MOHAN" This scheme is used against Weak NT (max 15) openning 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:..30: "LEBENSOHL-FAST" This convention is used when opnents bid at 2level after our 1NT opening Responses: 2//: NF, 4+ 2NT: forces partner to bid 3.

If Relay auction ends by 3(including) then next No jump suit bid is "RKCB-E"[6] and Jump to game is STOP. If Relay auction ends at 3 or higher then next scheme is used 4: ART; Announces STOP sequence; Partner is obliged to bid 4 and then to pass any Suit Game bid; 4NT bid in sequence 4-4-4NT Invites for a reserve to 6NT. Other suit bids are "RKCB-E"[6] according next rule. Suits are ordered according their length from the longest to the shortest. If more than one have the same length or can't be recognized then higher one is considered as longer. The closest bid (except 3NT and 4) is used for the longest suit, next bid for the 2nd ... 1st suit asks for the longest announced suit. If more than one are possible then the highest of them
