What does it mean?

[axu2008]

I would like to guess: the 3D invite to 3N if opener has stop in D (could be C depends on the style). the S is not the problem since the 2nt bid. Opener either bid 3H without stop or 3N with stop in D ©.

So I come to 4 hearts, 1diamonds, 4-5 spades, 3-4 (small) clubs, 8HCP-10HCP,

if 8HCP - they should be kings and Aces.

Wouldn't that hand have raised 1♥ to game on the first round?

Not necessarily, but you have a point: the hands I outlined may already

qualify as a limit raise, so the HCP count is to high, make it max. 8HCP. (*)

 

I was assuming 2H to be a constructive raise.

 

(*) I know the original hand.

 

With kind regards
