manudude03 Posted July 3, 2012 Report Share Posted July 3, 2012 5D looks like a much better contract than 3NT. 3NT is off on any lead provided they switch to clubs in time. Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted July 3, 2012 Report Share Posted July 3, 2012 Does that 3♠ explanation include "likely stop in S"? I would think that bid is looking for a spade stopper, not showing one. Quote Link to comment Share on other sites More sharing options...

I posted this hand because I had this hand avaliable at the time. Quote Link to comment Share on other sites More sharing options...
helene_t Posted July 3, 2012 Report Share Posted July 3, 2012 I don't think gib's methods are so bad here. 2♠ shows a fit and once a fit has been found we show stoppers, we don't ask for them. GIB probably made simulations based on the interpretation that 3♠ shows a spade stopper and found a diamond contract to work better than a notrump contract, probably due to the lack of a club stopper.
