South should bid 2H over 2C, NS was lucky, that EW did not take the money against 3CX

GIB thinks X of 2S is penalty, probably based on Pass first followed by X is normally penalty. I think that is a good rule

Yes, 2h non forcing is correct (about 4-8 HCP). So the rule is: if I have 4-8 and a 5card suit which I can show at 2-level, then I bid. Let's say the bidding is p 1nt 2c 2h p p 2s

we can bid now 3d as partner knows we are weak.

It seems that transfers are used here

Yes, after a 2C overcall it is system on - D = Stayman all other as without the overcall.
