I played the same hand yesterday. After 1♠ - (2♣) - 2♠, East didn't introduce his hearts but raised clubs, and I played 4S: 1♠ - (2♣) - 2♠ - (3♣) 4♠ - all pass After the club lead, I played the ♠K (the line suggested by flame), because I have only one entry to dummy (of course, trumps must be 3-2) This line wins when LHO has both the missing major aces. If they are bad placed, after losing two hearts and ♠A, I can still win playing West for ♠AJ or ♠A9 (as it was), intrafinessing (is this correct?) the ♠T from dummy. As the cards lies, playing a small diamond to ace loses because West has only one diamond. In the real life, West (who didn't now my diamonds' length! ...and yes, wasn't very brilliant ;) ), shifted to diamond at trick 3, and now I win with both ♠A9 or ♠AJ on my left: ♦A, ♠Q and all the diamonds, East can ruff but I lose only one heart.
