Playing with cherdano on BBO, we had the above auction. 2NT showed both minors, and the first double showed a good hand with at least one 4-card minor. After that, all calls were questionable to say the least.
West leads a small spade, won by East's king.
East returns the queen of spade, covered by you, and ruffed by West.
West plays a low diamond.
Plan the play (you may assume that you can still make it, i.e. that west started with 2 hearts and east with 1).
As usual, more advanced players please hide your answer.
