Partner dealt and opened ONE DIAMOND, and, with opposition silent, I bid ONE NOTRUMP all passing. I proceeded to rack up nine tricks. Sadly, it was IMPs.

The lead of the FOUR of SPADES was won in hand by the QUEEN, and when I led a low diamond, the KING popped up to be topped by the ACE. I then advanced the CLUB KING, which was won by RHO's ACE, and he returned a spade won by his partner's ACE who then cleared the suit, I win the third round in dummy. I play a heart to the Queen, all following small. A diamond to the Jack proves the suspected split as Lefty pitches a low club, and a diamond to the Queen also fetches a club pitch. I cash the CQ and CJ, and the following three cards are left.

Moi. H:xx D:x dummy H:Kx Dx and since LHO is hanging on to a spade and two clubs, RHO has two hearts (AJ) and a master diamond.

I play the losing diamond from both hands, RHO wins and cashes HA and gives dummy the ninth trick.
