jdonn Posted February 12, 2018 Report Share Posted February 12, 2018 It's a good point. There is a new version coming out soon and this isn't covered, but hopefully it will be later on. Quote Link to comment Share on other sites More sharing options...

The 3D is not forcing because north was a passed hand. However, I think that south's hand was much too good for a simple raise. After the 2D response south should make sure you reach game (at least). That being said, I would not have passed 3D with north hand, even with a void in partner's first bid suit. You are looking at an ace, 6 trump, and 2nd 5-card suit! I like 3S cue bid after south's raise to 3D. That should insure that reach at least 5D. Will see what the experts say. Quote Link to comment Share on other sites More sharing options...

The point of my post was that either the explanation for the bid is incorrect in a pretty bad way, i.e., it says a bid is forcing when it isn't. Or, the bid is supposed to be forcing and there's a bug in GIB that is allowing it to pass a forcing bid. Quote Link to comment Share on other sites More sharing options...
smerriman Posted February 17, 2018 Report Share Posted February 17, 2018 GIB often passes "forcing" raises of a minor, even if north wasn't a passed hand - see eg http://www.bridgebase.com/forums/topic/74820-another-clearcut-bidding-hole/ which I reported mid-2016 (still occurs).
