Is it completely crazy to bid 3N instead of 4H here? I did, with the following thoughts:
1. The opponents bidding mannerism suggested to me that almost all of the outstanding points were with RHO
2. With probably 24-25 points, seems like just choosing game with best possible chance to make (rather than thinking about overtricks) makes sense.
3. I have 6 losers in hearts and partner had to cover 3 of them in 4H vs. merely needing 2 winners at 3N (assuming the hearts run)
4. NT puts the stronger opponent hand on lead
5. If partners points are in tenaces, opponent strength lies over them. If partners points are top cards, seems like 2 outside tricks and the NT game should be in the bag.
Anyway, it worked on this hand (3N making 4, top board), but the question is whether there's a case that 3N is the best long-run percentage action.
If you think 4H is the better bid, is your answer the same if it's IMPs?

1S-(2D)*-2H-P*
2N-(P)-???
*Both opponent bids with confidence and zero pause or apparent problem
