West cashed ♥ AKQ, East discarding ♦ 2 on the third ♥, and West then switched to ♠ K. Declarer won dummy’s ♠ A and crossed to ♣ K in case ♣ Q was singleton. He cashed ♦ A, led ♦ 9 to ♦ Q, then advanced dummy’s ♣ 10. When East played ♣ 6, the moment of decision had arrived. Which opponent held ♣ Q – was it West, the opponent who opened the bidding; or East, likely to hold longer clubs as he held fewer major-suit cards?
Because West would have bid the way he did regardless of whether or not he held ♣ Q, the key motto is this week’s Tip. In fact counting the hand reveals that ♣ Q was certain to be with East – West had revealed five cards in each major during the bidding and followed to two rounds of ♦s and one of ♣s: no room for ♣ Q. Declarer correctly ran dummy's ♣ 10, then remembered to cash ♦ K discarding ♠ 5, before leading ♣ 9 to ♣ Q and ♣ A.

ANDREW’S TIP: Generally play the missing high card to be with the opponent holding greater length.
