This afternoon I was playing a bit online and we had some pretty interesting deals. It's not at all common that you get dealt 2 grand slams in a short period of time, especially at the same suit. I once bid and made 2 grand slams right after each other (7NT and a 7♥), so my record still stands.
These were played today:
The auction (playing 2/1 GF, opponents silent):
1♥ - 1♠
2NT - 7♥
Who needs science? I think playing relays I'd make like 10 rounds of bidding to end up in the same contract with a bit more accuracy. The contract is almost 100%.
I'm not always sure what's best with such hands: either 1♠ or 2NT (GF with fit). I would never splinter immediately since the hand is too strong, but I'm almost sure that the contract will end up in some number of ♥s... Does anyone have some good ideas why one approach would be better than the other?
The other slam was not as good:
The auction (still 2/1 GF, opponents again silent):
1♠ - 2♠ (constructive raise)
3♥ - 4♥
4NT - 5♥
The auction was better, but ♥s have to split 2-2 so it was a poor slam. Partner knew we had a double fit and all the Aces, so WITH ♥Q it would've been a great grand slam. On the current layout we were lucky enough to bring it home.
