This deal is from the Manchester Green Point Pairs last month. After a quick auction West led the ace of diamonds and continued with a diamond to East's king. A third diamond was ruffed by West, who then played a heart to East's ace. East now played a fourth diamond and when South ruffed with the six and West could not overruff declarer decided that the trump position was likely to be as in the diagram above. South played another heart, won by West who then played a club to South's king. South now ruffed his winning queen of hearts, then played the ace of clubs followed by the winning queen of clubs, again ruffed to shorten declarer's trumps.
The end position was now as below
South now ran the eight of spades to end play East for one off, a reasonable score on the board.
Thanks to John Currie who played and reported this deal.
