1eyedjack Posted March 14, 2014 Report Share Posted March 14, 2014 I have some sympathy for your point. But it may be at least in part a problem with the system. 11-15 is quite a wide range. While game is likely to be a good spot opposite 15, on the other hand 2N may be at significant risk opposite 11. I suspect that, from North's perspective, South is rather more likely to have 11 than 15, and may have done some sims to confirm it. Just guessing, mind. Not saying the system is bad. There may be no good or risk-free solutions for how to bid bal 11-15 hands in protective seat Quote Link to comment Share on other sites More sharing options...
iandayre Posted March 15, 2014 Report Share Posted March 15, 2014 This hand is worth more than 15 with 3 Aces and a King, 2 10's and 5 card suit. That said, doubling planning to bid 2nt next time showing 16-18 can easily get you too high. Quote Link to comment Share on other sites More sharing options...
Stephen Tu Posted March 16, 2014 Report Share Posted March 16, 2014 This is not at all close, North has to invite with 11. Even catching partner with an 11 count, 2nt will often be OK with west often getting endplayed. 11 to me is auto-invite opposite a weak NT, and this is 11 with a semi-decent 5 cd suit, and with an isolated opponent!

lycier Posted March 16, 2014 Author Report Share Posted March 16, 2014 Now you look at another hand.

Antrax Posted March 16, 2014 Report Share Posted March 16, 2014 Either way it seems poor. I wonder how much GIB needs to invite here. Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted March 16, 2014 Report Share Posted March 16, 2014 On the second hand, if the 1D opener had held Qxx(..) of Diamonds, which is frankly more likely than xxx, then 1N would have been the limit on the hand, so I say well done to North, and bad luck.Whether bidding to 2N and going down would be equally bad luck I do not really know. But on the first hand I agree that North is just too good to pass. Quote Link to comment Share on other sites More sharing options...
steve2005 Posted March 18, 2014 Report Share Posted March 18, 2014 Balancing is usually a weak NT and vs a weak NT like Stephen says you invite on 11. I suspect the hands you balance with 1N on 11 are good ones. I suspect GIB invites on 12 which is going to be pretty rare as it will often find some action in 2nd seat with 12 Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted March 18, 2014 Report Share Posted March 18, 2014 Still leading ♠K on the second hand, despite what the convention card says. Quote Link to comment Share on other sites More sharing options...

Antrax Posted March 18, 2014 Report Share Posted March 18, 2014 Yeah, this looks just like a "book" issue, GIB needs to be updated to always invite on (semi)balanced 11-counts here. Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted March 18, 2014 Report Share Posted March 18, 2014 Your conclusion may be valid (indeed I agree with it), but as examples to advance the argument I think that the second and third hands have flaws. On this latest hand, 3N is beaten on a Heart lead, and it is not trivial to make it on a Heart switch following a Spade lead, requiring some guesswork which on other occasions could fail. Furthermore we cannot be certain that GIB would have defended the same way against 3N as it did against 1N. Your decision to bid 1N with 5-2-4-2 shape may have been influential in GIB's mis-defence. I cannot be certain but I suspect that it is contrary to how GIB would have protected and therefore contrary to GIB system. As you now will be well aware from countless threads GIB will assume that your bids are systemic and will plan its defence accordingly, and departures from system will mislead the defence. Is it fair to expect a GIB partner field that possibility? Quote Link to comment Share on other sites More sharing options...
Antrax Posted March 18, 2014 Report Share Posted March 18, 2014 3N isn't always a great contract, but right now it looks like you'll consistently miss 25-HCP NT games after balancing. Quote Link to comment Share on other sites More sharing options...
lycier Posted March 18, 2014 Author Report Share Posted March 18, 2014 If balancing 1nt is 11-15hcp,this range is too wider to bid precisely , it will lead to unnecessary guess,as we know that it is a golden bidding rule to avoid final guess.We should say it is not a good policy without invitational sequence.

lycier Posted March 19, 2014 Author Report Share Posted March 19, 2014 the hand balance is key,especially without decent major suit,what you said is nothing to do with too wide rang. Quote Link to comment Share on other sites More sharing options...
