South was extremely suspicious of East's.thirdhand non-vulnerable bid, but he passed both to await developments and to insure North's understanding that when he did bid spades he had the suit. (Obviously, with a hand big enough to warrant a cue-bid, South could have bid two spades at once) East's failure to rebid the spades convinced South that the player's bid was either a psychic or based on a short spade suit.
East's double of the two-spade contract was foolish. If the opponents were in the wrong spot it gave them a chance to get out; if South really had good enough spades to make his contract, the double would cost a game.
West opened the heart ten, East's queen winning when dummy ducked. South won East's lead of the club jack and led the diamond ten. West took the diamond ace and returned another heart, which dummy won. The spade nine was led and finessed. Then a heart was ruffed by South, ihe diamond king taken and a club led from dummy. East ruffed to prevent South's scoring an overtrick, but could not prevent his taking three more trump tricks.
