After cashing a second spade, West knows to shift and the ] shift beats the contract. 1 NT NT Opening Lead: 4 Prefer majors to minors when on lead. The opponents won't have lots of hearts on this auction (but might have lots of either minor).

South's normal switch to the ]6 sets the contract. 1 NT NT Opening Lead: K West ignores East's T1 signal and plays spades until dummy's @A is dislodged. When clubs are playerd, East's count signal tells West to win the SECOND club. Dummy takes only 1 club trick. 65 4 AJ106 KQ107 J98 1042 QJ1087 Q854 A AKJ987 104 1 2 87 952 J862 94 2 2 AKQJ9 A1042 7 KJ7 A2 A654 9 72 KQJ1098 4 Q2 KQ4 4 4 A5 KQ65 8765 K2 1096 654 Opening Lead: K East-West discover there is no heart control.

North plays a 4th heart and South overruffs dummy for down 1. 1 Dbl 4 Opening Lead: 7 West wins the #A and returns a S.P. #10. When East ruffs, he knows to play a diamond (not a club) to West's ace for a second heart ruff.

When a low club is led from dummy, South must play low to give declarer a guess. 4 1042 10984 542 96 QJ9 AQ A87 AQ2 K65 762 QJ9 875 A87 KJ5 K106 KJ104 1 NT 6 NT Opening Lead: 10 East must not cover the first spade honor from dummy.

When he wins his diamond honor, he should continue spades. 1 2 4 Opening Lead: A On the @A (from AK) lead, North discourages. South switches (a trump is as good/safe as anything). Declarer must lose spades and a diamond (assuming the defense makes no mistakes).

When in with the [K, West continues spades to set the contract. 1 1 1 NT NT Opening Lead: 4 Whether East responds 1[ or 1@, North's most attractive lead is the 4th-best spade. South plays the 9. When declarer has to win the ace, the entire spade holding is revealed. When North gets in with a high diamond, he knows to lead a low spade to partner. The defense gets spades and 2 diamonds for down 1.

If declarer starts diamonds, he should lose tricks in that suit. Instead, he should draw 2 trumps, eliminate the clubs and hearts, and throw the defense in with the rd spade to break diamonds. 2 4 5 Opening Lead: A East opens 2@ and after South's overcall, West bids a LAWful 4@S. North guesses to bid 5[ against which the @A is led. Declarer ruffs, draws trumps (while stripping spades in the process) and cashes three hearts ending in dummy. When he plays a club and East plays low, South inserts the ]10 and claims (if East played the jack, South would cover with the king and also have a claim). 4 KQJ10 9765 J876 AQJ 2 J10986 J986 KQ98 AJ10765 1 1 5 A42 A4 K 2 4 K7642 1095 42 AQ9 AJ10987 KQ65 4 A5 K4 A2 42 9876 QJ1082 K105 8 4 KQ72 Q1075 Opening Lead: Q After a straightforward auction, South leads the #Q. Declarer should not play diamonds himself. He can guarantee the contract by drawing trump, stripping the hearts and exiting with Ace and a club. When the defense has to break diamonds, declarer is sure not to lose tricks in the suit (just cover any card South plays). 2 2 NT 6 Opening Lead: K After West's weak 2[, East can explore for slam with 2NT. West can show his club feature and East has no reason to use Blackwood--he just jumps to slam. Declarer wins the @A, ruffs a spade and draws trump while also stripping the black suits. He leads a heart from hand and covers anything North plays to claim his contract.

Declarer trumps high (saving the @5). He draws 2 rounds of trump ending in dummy (saving a second dummy entry). He takes a club finesse and then crosses in trumps to repeat the finesse. 1 2 4 Opening Lead: Q Declarer has to lose 2 clubs and at least 1 heart (needing a -2 break). The spade loser can go on the diamonds. After winning the ]A, declarer must play ace, king AND ANOTHER trump. If he doesn't play the third trump, North can ruff the rd diamond and declarer never gets the 4th diamond.

He can't afford the @Q at trick one. If it loses (as it does), the spade continuation sets him. He plays LOW from dummy and can't be defeated. 1 2 2 2 NT NT Opening Lead: 5 Declarer has 7 top tricks. He should test diamonds with the ace and king. If they split, he concedes a diamond and has an overtrick. When they don't split, he tries clubs and the - split sees him home. Ducking a diamond first is wrong, because it puts all the eggs in that one basket.
