In this deal, how should South plan the play in 4♠ after West cashes two top Diamonds, then shifts to a Heart?

North's 2♥ response was a transfer bid, showing five-plus Spades and any point-count. South's 3♠ rebid guaranteed four-card Spade support and a maximum. (This hand was borderline because of the potentially useless ♦Q x).

There are possible losers in both black suits. If the Club finesse is working, there will be no problems, but if it is losing, the Spade Queen will have to be found.

The key is the bidding. Since West passed as dealer and had seven points in Diamonds, he will not have both the ♠Q and the ♣K. As a consequence, declarer should play a Spade to dummy's Ace, followed by a Spade to his Jack. Here the finesse wins, so South draws the last trump and tries the Club finesse for an overtrick. But if the Spade finesse loses, the Club finesse must be winning and the contract is safe.
