There are at least 3 choices here in my opinion. 3H, 3S, and 4c. I chose 3H and was raised to 4H by pickup partner. The game was matchpoints and I didnt want to bypass 3nt. I thought 3 spades was misdescriptive, and did not bid 4c for fear of missing 3nt. Please indicate what and why you think it is best. It is South's turn to bid over 3D. It is also clear that 6C is best contract. How to get there is another question. This hand was played 43 times on okbridge with the following results: 6C arrived at 5 times
6D arrived at 1 time
3NT " at 25 times, making 7times, failing18 times
5C " at 5 times, making 6
5D " at 1 time making 6 because of doubleton 10D
other 6 times were partials in 3C or 3D.
