South reached 4 (no opposing bidding) and received the J lead. The J held and the next diamond was ruffed by declarer. Following general principles, he went to work on his long suit. He led a low club. Not wanting to "ruff on air," West discarded a diamond. Dummy's A won. Now what?

After some slow, tortuous twists and turns, declarer eventually took 10 tricks (but could have been set along the way). The ping pong ball went back and forth as declarer should have been set but was allowed to struggle home. Do you see a simple way to avoid the torture?

After the A wins at trick 2, declarer has a "sure" (barring any ridiculous breaks) thing. Trump dummy's remaining diamond. Lay down two high trumps. Cross to the A. Play dummy's other trumps (needed if spades are 4-1). Then take a marked club finesse and claim 10 tricks (2 diamond ruffs in hand, 4 spade tricks, A and 3 club tricks) -- easy-peasy.

At the other table, West bid 2NT (red suits) over South's 1 opening. East-West sacrificed in 5 doubled, down only one.
