WBridge5 played well to make 3 x, but if Jack (East) ducks the opening lead the contract will be defeated.  WBridge5 will cash the ♣Q and ♣J and then either (1) lead a trump or (2) lead a diamond to the ace . In both cases the defense will come to five tricks. In case (1) the defense takes 3 hearts and two spades, and in case (2) the defense takes either four hearts and one spade, or three hearts and two spades, depending on declarer's continuation.

East's 4 bid made it difficult for South to compete.

Opening leads are all important The opening lead of the Q and the defense not switching to clubs at its first opportunity, set up West's 5 (over North's 4) for the 10th trick.

WBridge5 +11 IMPs
