Creeksider Posted March 9, 2011 Report Share Posted March 9, 2011 GIB will now open 1NT with five of a major. It would be interesting to learn what criteria GIB uses in choosing between opening 1NT or 1M, if that information is available. Quote Link to comment Share on other sites More sharing options...
uday Posted March 9, 2011 Report Share Posted March 9, 2011 It will open 1N in preference to 1M with: 15-16 HCP5M5332 Quote Link to comment Share on other sites More sharing options...
Creeksider Posted March 9, 2011 Author Report Share Posted March 9, 2011 Does not distinguish whether doubleton is in the other major? It seems this would make it common for GIB to open 1NT with a 5-card major, indicating GIB's CC should be updated with that box checked. Also, the description of the CC still says 1NT denies a 5-card major. Quote Link to comment Share on other sites More sharing options...
Creeksider Posted March 9, 2011 Author Report Share Posted March 9, 2011 Traveler I notice on this hand GIB opened 1NT 13 times and 1H 3 times, holding five hearts and 16 HCP. I played this hand before seeing the change and produced a bottom score by leading hearts based on the assumption partner must have at least six of them.

Bbradley62 Posted March 9, 2011 Report Share Posted March 9, 2011 Actually, 14 EastGIBs opened 1NT and only 1 opened 1♥. One East isn't a GIB, and one who opened 1NT got to 5♦ after South interfered. You got a bottom board because you misled your partner by leading the ♥6. On the first trick, he figures you for an honor, so he puts up his K. Later, he pitches a heart, still thinking you started with honor-third. Partner doesn't make these unfortunate plays if you lead your ♥8, as is standard, instead of your ♥6.
