Playing on OKbridge tonight, I picked up:
♠A ♥A K Q 10 8 7 5 3 ♦J 8 2 ♣K.
Right-hand opponent passed and I opened a precision 1♣. LHO jumped to 2♠ and I almost fell out of my chair when partner, Kate, bid 3♥. With Brent I play transfer positives, even in competition, but with Kate this showed 5 or more hearts and 9 or more points.
RHO jumped to 4♠ (naturally) and I bashed to 6♥. LHO bid 6♠ (don't you just love it when they preempt and bid again when their partner could have anything) and Kate doubled.
Here are all four hands (rotated):
The opening lead was a heart. Declarer ruffed in dummy, discarded a club and led a diamond to his 10 and Kate's king -- we could no longer set the contract more than four. Plus 800 was -1.87 IMPs. If I had bid 7♥, East would have to find a diamond lead to set the grand slam.
