We had discussed enough that I knew that double was penalty, however I had no idea what any bid meant after that. My fear was that we were missing a vulnerable game and maybe even a vulnerable slam. I felt for my partner to penalty double at the 2 level he needed to be quite a bit stronger then he actually was. He has all of 4 tricks and I haven't actually promised much yet.
3nt was down 1. No one played in 2♥, though one person was in 4♥x down 3. 4♠ makes if you trump finesse east for the ♥king.
Assign blame please, I sure did at the table and I might owe someone an apology!
