After two passes and the dreaded multi 2 diamonds, I didn't have enough for a 2NT bid, but since LHO was a passed hand and the vulnerability was favorable, I felt that was more representative than the classic double with a balanced 13-15...
I sat down to watch a few hands the first day of the Masters LM pairs in San Francisco (where it is currently wonderful: sunny and in the 60's). Came across an interesting bidding hand with some play points.
Partner's opening is precision, so 11-15 HCP. His 4H is a good club raise with a singleton or void in hearts. Partner could still be relatively short in diamonds such as 4-1-3-5. East's 5D is probably a lead director with diamond honors (though a void is possible, partner could be 2-0-6-5 or even 2-0-7-4).
Over I can DBL to show limited interest in bidding on, P to show some slam interest, or bid 5H to show my ace and force to slam. Forcing to slam is too much with the threatening diamond lead, so the choice is really between pass and DBL. South actually passed, though I think DBL would have been wiser (if partner passes over 5H showing interest even opposite your discouraging DBL, you might then bid a slam). The auction continued as below getting to a poor slam. The diamond 5 is led. Main chance is 3-3 diamonds, but might as well play ace and another (no need to go down 2 if diamonds are 5-1). When diamonds didn't split declarer tried to sneak the by, but West alertly covered. Down 1. Note though that if we move the spade jack from West to North (instead of the useless club jack) slam makes.
