North discards a second diamond on the last heart. By now it is clear that he is keeping four spades, so declarer discards a spade and South throws a diamond. Three rounds of spades complete the non-simultaneous double squeeze: to keep his club winner South must throw a diamond, and now dummy’s two diamonds are winners. A diamond switch at trick two breaks up the double squeeze, but does not defeat the slam. If North switches to a low diamond, declarer wins South’s queen with the ace and cashes two clubs before playing hearts to expose North to a spade-diamond squeeze; if he switches to the king declarer wins and cashes major suit winners, ending in dummy, to squeeze South in diamonds and clubs.
