iandayre Posted July 13, 2014 Report Share Posted July 13, 2014 Apparently GIB always considers only the next bid, not the rest of the auction. Clearly, doubling again, intending to pass partner's 4H call, which will happen 90+% of the time, is nonsensical. I would never have doubled the first time, much less the second. GIB simply can't evaluate its own long suits. Quote Link to comment Share on other sites More sharing options...
steve2005 Posted July 13, 2014 Report Share Posted July 13, 2014 Sure E Gib has good hand but can't get to 5♦ unless Gib mentions the suit. First double OK, but I'm sure some humans would disagree and overcall, but second double just makes no sense, Gib should know W Gib is gonna bid 4♥ which is hopeless. So instead of doubling Gib should bid 4♦ which shows a big hand with ♦. Quote Link to comment Share on other sites More sharing options...
