Reoccurring bug in GIB bidding: after responding 1S to 1H, GIB will rebid 2S over opener's 2 of a minor with weak 6-card Spade suit instead of bidding 2H with 4-card support, i.e., a known nine card Heart fit.

This has happened to me and my BBO friends several times.

See an example in the attachment and in this link: http://online.bridge...ayed=1296328501

I'd have bid 2H with N rather than 1S ("support with support"). Coding this into GIB would certainly help eliminate some of its interesting decisions to bypass fits / get into a mess.

Of course, I'd X with East as well [after 1H-1S] and end up in 3DX-2, so make of that what you will :D [But then again, NS can make 5 hearts.]
