After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
And this is a "weakness" of the simulations? All I can say is "Wow..."
After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
Maybe there is a symantics problem here. In my view, "Matchpoints" is MPs, not IMPs. Being in 1NT +90 instead of 2 +110 costs the same as being in 1NT -200 rather than 2 +110. Read: http://www.rpbridge.net/6b00.htm, where it clearly states that "at ...

You guys are having way too much fun. :-)
David Libchaber's bidding problem: A7 KQ AQ94 AK642
I confess that I was the partner that pulled the 3NT contract to 4. And, when dummy came down and showed: xx Axxxx Kxx xxx I couldn't have been happier that I pulled it; I was so certain that with that dummy the hand must play better in ...

You have a point -- 6 is an good slam with these two hands.
After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
I'm missing your point. This is an MP problem, not an IMP problem, so unless you're thinking that vulnerability makes a difference to opponent's bidding (in which you would have a point), the comparison of 1NT to 2 is insensitive to vulnerability.

Doug, I ran Bridge Analyzer with the same sample size and biases as you state above, and I can confirm your numbers as being replicated by Bridge Analyzer, within a tolerable margin. Bridge Analyzer does take it one step further and calculates the advantage at MPs by comparing the DD ...
After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
Actually, if you fix opener at two hearts, the simulation says 2 is better than NT whenever responder is at least as shapely as 5-4-2-2. But if responder is 5-2-3-3, 1NT is marginally better than 2.
After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
You might be surprised to learn that the simulator says that under the conditions of the OP: Qx Q6432 Jxxx Kx favors 2 over 1NT at MPs by 68% to 32%. xx KT987 QJT9 Qx favors 2 over 1NT at MPs by 69% to 31%. Not much difference ...

Hah...yeah, me too in robot games -- the robots are so stupid. :-)
