BRIDGE
YOU are South, declarer in 4♥, against which West leads the ♦Q. Plan the play.
THIS is quite a hard one, because all your instincts will tell you to win with the ♦A and return to your own hand via a trump in order to lead towards the ♠K. But if you do, and East is able to win with the ♠A, he will spot what you are up to and return a trump.
That will be two trumps gone from dummy, and the opposition will knock out the third when you lose the second spade — and it isn’t difficult to count that you must get in a spade ruff to make your tenth trick.
The answer is to win the opening lead in dummy and immediately lead a spade. Now you have the tempo, and the defence haven’t time to draw three rounds of trumps before you are ready for your spade ruff.
