a very interesting ending

Spades are trump, the end position is that dummy has a trump and a master diamond (the beer) and my hand has a trump and a small diamond.

Opponents are void in both spades in diamonds. On the 12th trick, my LHO is in, and in order to score the beer, I had to ruff and ruff.

Maybe it isn't that interesting to you, but I was the one who beered.
