Answer

S 86 H AJT9543 D AT C 64

4H Again, this isn't a clear cut bid. 3H, then rebidding 4H is a possibility. It shows a slightly better hand than this. But 4H shows a slightly worse hand. I base the decision on two points.

• We want to be in hearts, always.
• Missing a making slam by underbidding is less likely than getting too high by overbidding.
