First, I don't know when GIB switched to 2/1, I'm not very familiar with 2/1(than sayc). But now the GIB bidding have lots of problems, after this hand I became crazy [hv=pc=n&s=s2hak742dj874caj5&w=sa876hqj6dt93c964&n=sjt53ht9dakq65c87&e=skq94h853d2ckqt32&d=n&v=e&b=9&a=pp1hp2dp3dp4hppp]399|300[/hv] I'm completely shocked when dummy shows only 2♥ so why didn't we play in ♦? It was too lucky that GIB led a club and heart broke 3-3, thus contract made I've seen a few more hands that GIB didn't have enough trumps to make a rebid - when I move cursor to the bid it showed 5 trumps, so I raised with 3, and I found we were in 4-3 contract
