This deal from a duplicate at Cheadle Hulme featured some interesting bidding decisions and defence points.
After East's opening bid South chose to pre-empt with four clubs. This may have worked, but South has too much defence for this bid, a simple overcall of two clubs is to be preferred. West now doubled for take out and East decided to pass for penalties as the vulnerability was favourable and there was no guarantee of making game. West chose to lead the seven of hearts which should work well. East won the ace and returned the two of diamonds. West should read this as a suit preference lead when South plays the queen and return the nine of hearts for East to ruff. Then East, reading West's nine as suit preference, can lead a spade to the ace and get another heart ruff. With the king of clubs to come that is three off and 800, ample compensation for the game available to East-West in four spades.
