Gib open 1H with 22 hcp in the balance hand.

This is my first time to find this kind of situation.

Flannery type hands (54) 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

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.

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?

Because, as steve2005 points out, in order to show both suits you would have to force to game.

 

You can have a bit less when you have a one-suiter in hearts or spades because

2*-2*

2-3*

3

is nonforcing. But

2*-2*

2-3*

3

is forcing.

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.

My oft-stated proposal is that stiff-A, Ax, Kx and AK-tight retain their distribution points rather than have them discounted for alleged duplication of values.

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.

So playing with GIB we are forced to keep the auction open with 4HCP? Or even a good 3?

 

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.

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.
