A mistake gone good

The majority of bridge-related stranglings occur after partner passes a bid that's clearly artificial, leaving you to play a contract in a suit you don't have. On this hand, sitting East, I bid Michaels, a bid of the opponents' suit showing 5-5 length in the unbid suits.

My bid of 2H indicated my length in the black suits. When South didn't overcall, my partner, Anne, was forced to bid -- but she didn't, and North schemingly left me in a doomed contract of 2H. The opponents didn't even double, because that would have given me a chance to escape. With just five trumps in the combined hands, I managed to take only two tricks out of thirteen, going down six tricks non-vulnerable for a loss of 300 points.

However, the joke was on the opponents! They could have made a foolproof grand slam in hearts or no-trump or even diamonds, worth 2210, 2220, and 2140 points respectively, so our unintentional sacrifice turned out to be a rare triumph, to the tune of 14.5 IMPs.
