First Play: West ignores conventional wisdom and leads his singleton Diamond. East takes his ♦K and ♦A and gives West his ruff. Now, with only two enemy trumps remaining, Declarer should play for the drop, and that is 10 tricks for Declarer. So, in this case, going after the ruff was not a success, West was indeed ruffing with a natural trump trick.
Actually, Declarer had a second compelling reason to play for the drop. If he were to finesse the Spade he would be playing West to have two singletons. Thatís not impossible, of course, but with such extreme distribution, and being non-vulnerable, he might have been heard from in the bidding, donít you think?
