What doctor would know what to do?

This is a French proverb: Greedy eaters dig their graves with their teeth. Sometimes, bridge players dig their graves by forgetting the play that calls to mind someone who works with teeth.

In this deal, South was in four spades. West led the club ace and continued with a low diamond. What happened after that?

North was surprised when West made a takeout double. He wanted to redouble in case the opponents were in trouble, but by partnership agreement that would have been fit-showing, indicating three-card spade support. So he settled for a natural two-no-trump rebid. Then South plunged into four spades.
