Another instructive deal from the Manchester congress teams finals.
South arrives in three notrump after West has overcalled in diamonds.
West leads the five of diamonds to West's ten and South's queen.
How do you proceed?
South should aim to lose the lead to West first so that East is out of diamonds when, or if, he wins a trick. So cross to dummy with the heart ace and finesse a spade. West wins and the defence clear the diamonds, South holding up the ace to the third round. Now South can finesse a club, but when East wins he can only play a heart. South now makes two diamonds, two hearts, three spades and two club tricks to make the contract.
