South was in 4H after 1H - 3H - 4H (E/W passing).
West led the ♦7. East took the AQ and gave West a ruff in D (ruffed with the ♥3). West now returned a spade to K.
South now played a heart from dummy and East played the J (!) from J8, South the K, and West dropped the Q from QT.
South ruffed a spade in dummy, and then finessed the ♥9 losing to the T for -1.
East has to play the J to bring about the deceptive play. If he plays the 8, declarer is forced to play for the drop.
Was this brilliant defense by E? or just lucky? or is this well known?
