and the relative success of 4 (i.e. limiting the loss to minus 500) is the diamond suit. It's one of those frozen positions that means whichever side leads one first will be sacrificing a potential winner. So, against 4 doubled North-South cash two hearts and switch to a spade - best defence. Declarer wins the ace and exits with another. If the defence don't attack diamonds the clubs are so positioned that two diamond discards are available from dummy. Try it. The best the defence can do is to switch to 
J , covered, and hope that declarer misguesses on the continuation. The probable result is a mere three off.
