Luckily for my heart, we were the sole team not to have to play this hand. But it generated some discussion at the pub afterwards. Our pubmate opened 2♣, and heard West bid 2♥, alerted as Suction - either spades or both minors. Her partner passed, which she alerted as a game force (an A, K, or two Qs). East bid 2♠, pass or correct, and South took the low road with 3♥. At this point West bid 3♠, and North finally spoke up with 3NT. This was passed to South, who found herself about to bid at the four level without really knowing what she needed to know about the hand*.
At other tables, South opened 2♣, there was a direct 2♠ overcall by West, and after South bid 3♥ North bid 3NT, putting South in a similar position.
1. Would you open this hand 2♣? If you do, what is your plan for finding out the specific information you need (partner's holding in the club suit)? We decided that in an uninterrupted auction, one could, after the presumed 2♦ rebid, hope to find out about a club control by jumping to 3♥ to set trump, asking partner to cue, but didn't know what to do beyond that.
2. What would you do after 3NT?
(*At the table, our pubmate chose what we all thought was a reasonable bid and her partner misinterpreted it, putting them in an impossible contract, so I'd rather not give the rest of her particular auction, but how to handle this hand - interference or not - sort of flummoxed us.)
