Just play out the cards

The World Wide Bridge Contest was held Friday night and Saturday afternoon around our planet. The boards are pre-dealt and participants get a booklet with all the hand records and an analysis by Canadian Eric Kokish.

I played at the Lightman Bridge Club in Memphis Friday evening. A Platinum Life Master was North and declarer in 4♠ on Board No. 6:

                 ♠ A K Q 8 5 3
                 ♥ ---
                 ♦ A 8 5
                 ♣ A 10 7 3
♠ 9 7                           ♠ 10 6 4
♥ J 6 4 2                       ♥ A K 8 5 3
♦ Q 10                          ♦ J 9 7 6 2
♣ J 8 6 5 2                     ♣ ---
                 ♠ J 2
                 ♥ Q 10 9 7
                 ♦ K 4 3
                 ♣ K Q 9 4

East led the ♥K. North ruffed and drew trumps. Then she played a high club from South, noting that East showed out.

"I can pick up clubs now," she said. "I have to give you a diamond."

What's wrong with this picture?

If you merely play out your cards, East is squeezed in the red suits. He has to save his ♥A, so with three cards left, he can only keep two diamonds. If she is careful, declarer can win trick 13 with her ♦5 (instead of the ♦8) for maximum style points.
