When you are virtually certain you know what the final contact should be my advice is to bid it immediately. The less you reveal the harder life will be for the defenders.<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

I remember declaring a tricky slam in a big tournament some years ago. I immediately played from dummy at trick one \u2013 it seemed clear which card to play. I won the trick in my hand and \u2013 with many clues from the bidding \u2013 was able to construct their hands precisely. But then I realised that I could no longer make my slam. I had needed to play a different card from dummy.<\/p>\n\n\n\n

So always think before playing from dummy at trick one.<\/p>\n\n\n\n

6♠️ Admirable brevity. A more technical approach, eg a 4♣️ Ace-showing cue-bid, is only likely to help East-West with their opening lead and defense. It\u2019s the 90 per cent rule \u2013 if you are 90 per cent confident you know the correct contract, just bid it. Don\u2019t faff about.<\/strong><\/p>\n\n\n\n

West led the 2 of Clubs against 6 Spades. With eleven top tricks, there were two routes to a twelfth: establishing a long Heart in dummy or a successful Club finesse. Though the Hearts offered a better chance, there appeared to be nothing to lose to try the Club finesse at trick one. Declarer tried dummy\u2019s Queen of Clubs.<\/p>\n\n\n\n

East won the King and, cleverly resisting the temptation to switch to the King of Diamonds, continued with a second Club, so removing a dummy entry. After winning dummy\u2019s Ace of Clubs, declarer crossed to the King of Spades, then set about the Hearts. He cashed the King, crossed to dummy\u2019s Ace, and ruffed a third round (with the Queen of Spades). West discarded on this trick to reveal the 4-2 split in the suit, and declarer was in trouble. He crossed to the Ace of Spades, drawing the last opposing trump, and ruffed a fourth Heart. Though he had established the fifth Heart, he had no way to reach it, as dummy\u2019s third Spade was (unavoidably) lower than all his remaining Spades. He lost a Diamond at the end. Down one.<\/p>\n\n\n\n

The key is to prevent the defense from knocking out the precious Ace of Clubs entry. To that end, declarer must play dummy\u2019s 8 of Clubs at trick one (key play). East wins the 10 (and might have played the King) but cannot continue Clubs without presenting dummy\u2019s Queen with a trick. He is likely to switch to the King of Diamonds. Declarer wins the Ace, cashes two top trumps in hand, plays King of Hearts, a Heart to dummy\u2019s Ace, ruffs a third Heart, crosses to the Ace of trumps, ruffs a fourth Heart, crosses to the precious Ace of Clubs, and cashes the fifth Heart discarding his Diamond loser. Slam made.<\/p>\n\n\n\n
