Partner opens 1 spade, the opposition overcall you raise partner to 2 spades, the opposition bid fiercely all the way to 4 hearts - using the law of total tricks with 10 trump cards between you you should compete and bid 4 spades. West in frustration doubles for penalties ! All Pass.

Plan Before You Play
Dummy's hand goes down, you notice immediately that you will lose 2 diamond tricks and 1 heart tricks so you must make all your clubs using a direct finesse and all your spade tricks (hopefully they are divided 2-1 and the QS will drop in order to make your contract.
The Play
Lose the first 2 diamond leads and the heart switch. On the first round of trumps leading low from dummy you notice East is out! so West has all the remaining high spades! you now know that 2 finesses against west for the QS will capture QS. Either try to drop the KC by playing your AC at round 1, or directly finesse the QC hoping West has the KC.
Comment
As it turns out the Club split 2-2 and the finesse fails. so unfortunately 4S goes 1 light doubled. However this is a much better score for your partnership (only -100 pts) than if East-West are left playing and making 4 Hearts vulnerable (-620 pts)
The above commentary is intended as a guideline only. As with any Bridge hand there are many ways to bid and play any hand.
