Okay then.
I wanted to bid 4NT after partner's heart raise because I didn't want to get too high and go set if we were missing the
♣A and
♥K.
The blast to 5
♣ on my right didn't make the slam any likelier, so absent the key-card tool, I plodded on and bid what I could make. Upon receiving competition at the 6 level, I was strongly tempted to, and probably should have, gone on to 6
♥ but I didn't want to jeopardize our plus-score on the hand. So I cracked it.
I was peevish at the sight of the dummy that came down:
LHO was a Young Turk, who took advantage of the colors to bid on nothing whatsoever. God only knows that if I ever tried this myself, I would hit 2=5=6=0, not 0=2=5=6, and I would go for a huge number and never be able to pick up another partner again.
We got three tricks and +300 against 6
♣ doubled, for a loss of about seven IMPs on the deal.
This should have been the par score: A spade ruff defeats a 6
♥ contract. However, enough tables were in 6
♥ making six, or even seven(!) that it was a very soft result. Should I have put us in there? I still don't know. However, most players here apparently would have gone on, so it appears that is the right action. Thanks for the input guys.
