manudude03 Posted July 28, 2014 Report Share Posted July 28, 2014 Well judged, partner has 3HCP and can't make game anywhere with best defense. Quote Link to comment Share on other sites More sharing options...
lycier Posted July 28, 2014 Author Report Share Posted July 28, 2014 Don't care about the result.Don't care about the judgement.It should open 2♣ with 22hcp in this balance hand.1♥ is a opening mistake . Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted July 28, 2014 Report Share Posted July 28, 2014 I think that opening 1H is borderline at worst. But that is just me talking. When I open 2C I really mean it. But then I am from UK. In US they tend to open 2C lighter, What they do in China I really don't know. Prob open strong 1C Quote Link to comment Share on other sites More sharing options...
steve2005 Posted July 28, 2014 Report Share Posted July 28, 2014 Flannery type hands (5♥4♠) difficult to bid and show shape economically. If Gib opens 2♣ it is going to have to GF if it wants to show it's shape. and this is not a GF hand and not good enough for a 2N rebid. (edit) may have 22 pts for a 2N rebid but who wants to rebid 2N 5-4 in majors?/edit Quote Link to comment Share on other sites More sharing options...
helene_t Posted July 28, 2014 Report Share Posted July 28, 2014 I would have gfd with that hand. Not that I feel strongly about it 1 Quote Link to comment Share on other sites More sharing options...
Antrax Posted July 29, 2014 Report Share Posted July 29, 2014 I would also open 1♥. It's not surprising GIB agrees because for GIB 2♣ and then suit is 23+ not balanced, and 2♣ into 2NT is 22-33, except it doesn't consider 4=5=2=2 to be balanced. So, the only option for it is 1♥.I'm guess lycier proposes modifying the limits by 1 HCP to tip this hand into the 2♣ opener. Quote Link to comment Share on other sites More sharing options...

I don't agree.As we know that Gib 2♣ and then suit is 19+,not 23+ in GCC.If 4=5=2=2,Gib usually bid 5-card suit instead of 2NT.any idea?

You can have a bit less when you have a one-suiter in hearts or spades because2♣*-2♦*2♥-3♣*3♥is nonforcing. But2♣*-2♦*2♥-3♣*3♠is forcing.

42krunner Posted July 30, 2014 Report Share Posted July 30, 2014 I look at that hand. It is a three loser hand. I open 2♣. I'd open 4♥ with that hand before I open 1♥. Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted July 30, 2014 Report Share Posted July 30, 2014 Regardless of how a human would handle this, I think there's a much more simple answer as to why GIB opens 1♥. GIB wants 23 total points to open 2♣; this hand has 22HCP, and any points awarded for minor-suit shortnesses are deleted for honors-in-shortnesses. So, if the major suits were switched, and a human could open 2♣ then show both majors without forcing game, GIB still would open 1♠ because he doesn't have 23 total points. Edit: I now see that this has already been covered above. Quote Link to comment Share on other sites More sharing options...

steve2005 Posted July 30, 2014 Report Share Posted July 30, 2014 its just one of the drawbacks of Standard American based systems. Sometimes your stuck and your best choice is to open at the 1 level with a very strong hand. This is one of the benefits of strong club systems it doesn't happen to them.

I realize that whatever the cut-off there will be a borderline hand. 22 seems a better cutoff than 23 to me. Given the typical Responder structure.

Given the typical Responder structure.I did not mean to comment on the appropriateness of 22 vs 23; I was trying to explain how/why GIB took the action he did based on his system. It's my understanding (I haven't played a f2f tournament in 20 years) that playing with anyone you need to keep the auction open unless the 2♣ opener rebids 2N.

My comment about keeping the auction open was directed to those times that GIB opens 1♥ (or more generally 1 anything). Yes, of course, over 2♣, we are forced to keep the auction open with the possible exception of systems that employ double negatives, either in 1 bid (as in 2♥), or in 2 (as in cheaper minor). I do not know who is merely expert on GIB ranges (as you are, apparently) and who has some authority for programming GIB. So I was making a suggestion to the latter group that 22 might be a better cut-off than 23. I do know that GIB uses cheaper minor for double negative so it would seem that it could easily handle a 22HCP lower limit to the range.
