1 HB31 Lebensohl after NT opening A 63 J 10 6 A K 6 Q K Q J A J J 3 95 K Q 543 Q 97 A K 2 Q Q A 63 K Q 543 J 10 6 J 75 A K 6 A J 10 Q 876 K J A K 3 95 K Q 543 J 75 A J 10 K J Q 2 A 8 J Q 43 K A A K 62 Q 876 K J A 10 5 A 9 A K Q 65 J 7 K 876 Q J 9 Q 3 K J Q 4 A Board 1 : Dealer North : Love all 2 3 Pass 4 3 is game forcing. If South wanted to just make a game try he would have started with 2NT and then bid 3. Board 2 : Dealer East : NS vulnerable 2 2NT Pass 3 Pass 3 Pass 4 West plays 3 after the Lebensohl 2NT as a game try, but it is perfectly reasonable to have an alternative partnership agreement that 3 is a sign off. With a maximum and 3- card heart support East raises to 4. Board 3 : Dealer South : EW vulnerable 2 2NT Pass 3 Pass 3 North plays 3 after the Lebensohl 2NT as a game try, but it is perfectly reasonable to have an alternative partnership agreement that 3 is a sign off. With a minimum and just a doubleton heart South passes 3. Board 4 : Dealer West : All vulnerable 2 2NT Pass 3 East uses this sequence to sign off in 3.

Board 6 : Dealer East : EW vulnerable 2 3 Pass 4 Pass 5 3 is game forcing. If East/West play that 2NT followed by 3 over 3 is a sign off, it follows that if West shows his diamonds he can only sign off or force to game. Board 7 : Dealer South : All vulnerable 2 Dbl Pass 3NT Dbl is a game invitation, not penalties. South must use common sense. With good spade stoppers and a maximum he jumps to 3NT. Board 8 : Dealer West : Love all 2 Dbl Pass 3 Dbl is a game invitation. With no spade stopper and a minimum West can only show his cheapest 4-card suit.

The 3 cue bid shows 4 hearts. With one, possibly two, spade stoppers and lacking 4 hearts, North settles for 3NT. Board 10 : Dealer East : All vulnerable 2 2NT Pass 3 Pass 3 Pass 4 2NT followed by a cue bid carries two messages. 2NT denies a spade stopper. The 3 cue bid shows 4 hearts. East chooses game in the 8-card heart fit. Board 11 : Dealer South : Love all 2 2NT Pass 3 Pass 3NT Pass 4 Pass 5 2NT followed by 3NT carries two messages. 2NT denies a spade stopper. 3NT denies 4 hearts. South now has a problem. There is no heart fit, and it is clearly wrong to pass 3NT because neither partner has a spade stopper. He can only bid his cheapest 4-card suit, 4. Board 12 : Dealer West : NS vulnerable 2 3 Pass 4 The 3 cue bid carries two messages. The failure to start with 2NT shows a spade stopper. The cue bid shows 4 hearts. West chooses the 8-card heart fit.

The failure to start with 2NT shows a spade stopper. The failure to cue bid denies 4 hearts. North will always pass this sequence. Board 14 : Dealer East : Love all 2 3 Pass 3 Pass 4 unspecified second suit. Since West doesn t know the second suit, it is pointless worrying about it. 3 carries two messages. Failure to go via the Lebensohl 2NT shows a heart stopper. The 3 cue bid shows 4 spades. East bids 3 to confirm the 4-4 fit. Board 15 : Dealer South : NS vulnerable 2 3 Pass 3NT unspecified second suit. Since North doesn t know the second suit, it is pointless worrying about it. 3 carries two messages. Failure to go via the Lebensohl 2NT shows a heart stopper. The 3 cue bid shows 4 spades. Without four spades South settles for 3NT. Board 16 : Dealer West : EW vulnerable 2 2 Pass 2 Pass 3 unspecified second suit. How East should bid is a matter of partnership understanding. A common method is that a double of the artificial 2 shows clubs, while bidding the anchor suit (hearts) is for takeout. With a minimum West bids spades at the lowest level. East makes one final game try, declined by West.
