Playing N/S with Gerry, came first with 65%.
P - P - 1C - 1D
X - 2D - 2H - P
3H - P - 4H all pass.
Morag should have bid more than 2D, I can consider bidding 4H instead of 3H, double fits are worth extra especially if partner is 4-5 hearts and clubs, however it was a third in hand opening, Morag and Susan won't bid without the values and anyway, Gerry isn't shy about bidding games.
How right I was, Gerry loves his singleton diamond and bids 4H.
Susan led QS taken by Ace, heart to K and A and Susan plays QD. Now Morag just has to overtake this (she knows from the bidding Gerry is singleton) and play a spade for a ruff and 1 down. However she probably isn't thinking that maybe seeing the lead as from QJx. Anyway Morag lets QD hold, another diamond ruffed, trumps drawn and Gerry negotiated the clubs for 1 loser, game made.
I expect it just went 1N - 3N via a heart transfer at the other tables and a small diamond was led. With hearts breaking a heart, a diamond and a club are all that are lost.
At our table Morag opens 1D and ends in 3N. Gerry led 9S taken in hand, A, K and another heart and Gerry plays another spade to Dummy. Two hearts cashed and now a club, ducked, I took the second club and simply end play Dummy with a spade. Dummy just has Kxx in diamonds left and Gerry has AQ diamonds and a spade for 1 down.
Mike led QC which I won with Dummy's Ace. This looks to be a great start if lead is the natural one from QJ9(x). I played spade to Ace and Katy dropped 10S. Now that really tells you nothing but does make QT more likely, however singelton is a little more likely as well making the finesse essential. Like I said, the 10 doesn't really tells you anything, you can play it from a variety of holdings. I decided to not play the finesse, cashed KS, back to AH with the intention of finessing 10C, cashing King for a diamond discard and with luck clubs might be 3-3 and another diamond discard.
Oh boy, losing finesse in clubs, two diamonds cashed and QS to come for 1 down
The perspicacious among you will have seen of course that 12 tricks are available.AC, A, J, K of spades, KC, ruff a club, heart to Q, ruff a club, heart to Jack cash a club throwing a diamond, claim all but a diamond. Only an idiot could go down on this hand.
