The 2h opener shows a 11-15, and a 3-suiter short in diamonds(4315, 3415, 4414 or 4405). I know that each side has a 10-card fit. Now what? Partner will seldom act in this auction since I know much more about his hand than he knows about mine.
Edit: Anyone going for pass or 3nt?
Edit 2: This is IMPs scoring, if it matters.
Funny. This looks so much more like opener forgot your convention and has a Weak Two in
♥.
Anyway, so each side has at least a 10-card fit, and HCPs are more or less evenly distributed. According to the Law of Total Tricks this means we are likely to make 4
♣, they are likely to make 4
♦, give or take a trick for each side (sometimes two). The bad news is, they have the higher-ranking suit. The good news is, they don't know what I know. How can we make the most of this?
I feel at MPs I should bid 5
♣. I don't think they will double this and even if they do and I go down for -100 while they can get +130, it's still good for us. If they bid 5
♦, I double. Down one doubled is +200 which could be a top score for us even if some on our side are allowed to play 4
♣ or below. If 5
♦X makes, next deal please.
At IMPs I find it much more difficult because I don't like the risk of driving them into 5
♦ if it makes while everyone else plays 3
♦+2, it seems too costly here. I guess I bid 4
♣ hoping that 4
♦ is the final contract. If that just makes, not much is going to happen; while if they make 9 tricks or 11, it can even be good for us. With vulnerabilities reversed and a slightly weaker hand, I would consider passing to let them sort out where they think they belong in a situation they find hard to evaluate correctly.
By the way, I strongly feel that opener should not bid again in situations like these. After opener strictly described the hand, partner may raise to any level for very different reasons with very different hands, so any rebid from opener is completely in the dark.
