Playing N/S with Gerry came third with a Butler score of 30.
Of course winning AH and cashing AK of spades gives you an easy 10 tricks, but where is your 10th if the Q doesn't fall? And what chance have you now if spades are 4-1?
What if West takes AC and gives partner a ruff? East can return a diamond to Q and A, South plays KS which East must take and has to exit with a spade or they give away a red trick. But now declarer can ruff a heart and discard the other on KC for 10 tricks.
Let's say however I bid 3S, Gerry will now bid 4D and say I venture 6D. West might lead a club, win the Ace, Ace and another spade won by the 9. Heart back won by Ace, KC, spade ruff high, AD, diamond to 10, spade ruff high, diamond to Q and two long spades to discard a heart and club for 12 tricks. Minus in spades was not good.
