Pickup at the club, with one of the best players there.
Our card says "sound preempts 1/2", and maybe I should have done that. But I couldn't decide whether to open 1 or 3, and ended up deciding "I'll get a chance to show this hand next round for sure" and passed.
LHO opened 1♠(!) in third, and, well...
Partner's only comment was "I know he saw my bid." RHO led his "obvious" trump, and by conceding the T and the K, eventually my partner was able to get to the board and pull the rest, to make 2.
But I've never done that before; probably never will again.
