Disaster!

Well, here it is, the most wrongheaded, convention-laden, screwed-up sequence that ever missed a cold slam. I've never seen a more flagrant misuse of conventions and doubt if you ever will. Eleven spades and six hearts and they wind up in . . . they wind up in . . . hearts?

Nine bids, every one of the first eight alerted to wind up not just in the wrong spot, but a flagrantly wrong spot. The opening bid looks like a short club forcing bid, as in Precision. Beyond that, I don't even want to speculate on what each bid means. I don't know and it seems evident that they didn't know either, unless you want to postulate a pair that likes winding up in such an inferior contract.
