Competition Problem 82a
composed by Sebastian Nowacki
East is on lead at no-trumps. North-South to make 5 tricks.
Successful solvers: Ian Budden, Leigh Matheson, Pavel Stříž, Daniel de Lind van Wijngaarden, Dick Yuen, Wim van der Zijden. I've raised the DR to 2 because two solvers missed the need to squeeze East.
East leads the ♦2, taken by the ♦ J. South cashes the ♣A and leads the ♥8, covered by the ♥9 and ♥10. North exits on the ♠2, triple-squeezing East. If East discards a minor suit card, South discards from the other minor suit and wins the last two tricks with the ♥7 and the established minor suit winner. If East instead discards a heart, South does the same so that North’s ♥A4 tenace takes the last two tricks.
