The bidding started on my right with an 2S showing 8-11 hcp and a (5)6 card suit (according to cc). LHO raised to 4S and it was my lead.
A blind lead from the minors did not attract my attention. I've seen more than a few of these where 4 tricks were cashable and the wrong lead resulted in overtricks instead, for example if a strong diamond suit would hit in dummy. I led therefore the ace of hearts. Dummy went down with:
Partner discouraged with the 7 and I promptly shifted to a diamond to dummys ace, partner signalling strength this time. Declarer played a spade to hand, partner following (declarer only 5) and led the T of clubs. What do you do? Quick decision!
I played low as I could see only one heart, one diamond and I figured a club misguess was our best shot. Declarer ran it and made 10 tricks on this layout:
Declarer could now repeat the club finesse but it didn't matter, it's easy to ruff your losers in dummy and come to 10 tricks. A misguess was our only shot. This deal cost 6 imps when our comrades missed this one in the first half against Texans.
According to the bulletin, I shifted to a low club in trick 2 and they claimed that a diamond lead and passive defence (including club cover) sinks the contract.
