South is on lead and needs 7 more tricks. He starts with the good heart. West discards a spade and north discards a diamond, but east has to find a discard. A diamond concedes the rest of the tricks and is obviously no good.
1. If east throws a spade, play the ace of spades and a low spade away from the king, throwing a diamond and a club from dummy. East has to part with a club now. No matter what west exits, the ♠K squeezes east in the minors.
2. If east discards a club, play the ace of clubs and a low club, ducking the king. Now the clubs are established.
