Explanation given for the 6NT bid is 22-24 HCP

[steve2005]

6N is an impossible bid.
Anytime 6N makes, 7 of something could have a very good play.
Unlikely but worse 6 of a suit might be making and 6N has no play.

The explanation for the 6NT bid is 22-24 HCP. GIB has 15 HCP. It doesn't matter what you think of the 6NT bid. It has nothing to do with the point. The point is that if the bidding goes 1NT showing 15-17 HCP and GIB has 22 HCP and a balanced hand, it's going to bid 7NT. If on this auction it thinks 6NT shows 22-24 HCP, why is it not bidding 7NT holding 15 HCP?

Because it thinks 22+15=37. A critical King could be missing since 3 points missing. I dont agree with 1H-6NT especially since a simple 2C is available as GF.

This is human sitting South, no?

6nt responses don't exist in normal partnerships except after 1nt/2nt openings, or 2c-?-nt rebids. So I don't mind GIB passing in response to 6nt not knowing what to do and and just having a vague guess of partner's range. What if partner had jumped on some 20/21 count and you are off an ace?

If anything it's good, train human not to make ridiculous bids like 6nt response. Let's concentrate on getting Gib to not do ridiculous things in normal auction, not trying to second guess reasonable action after human ridiculous bid.

Is looking like the 6NT bidder was a GIB. Would be nice to get that clarification.

because bidding is more than points. Having a source of tricks or a fit and first round controls you can make 7 on much less hcp
I presume Gib ran a simulation and didn't like it odds for 7N with 37 hcp.

You can never expect GIB to do something smart when you make an "impossible" bid. Don't be fooled into thinking GIB has a clue what 6NT means. The explanation is automatically populated based on the minimum HCP from 1H and the level of the bid. North GIB is still not aware what 6NT shows, and I bet will always pass it.

Obviously no one should care to fix this auction. But I find it extremely misleading to have such a precise explanation of 6Nt when in fact GIB has no clue what it means. Wouldn't "to play" be a much more accurate description of the partnership understanding?

Are there many places like this where the explanation given has nothing to do with GIB's understanding of the bid?

For another data point, 7NT showed 25+ HCP. On the other hand,

---

5♥ shows biddable hearts with no explanation of strength

---

5♠ shows biddable spades with no explanation of strength

so those are basically undefined bids.

Why can't opener determine what 6NT shows (22-24 HCP), if there is an explanation for responder's bid? That seems like a silly oversight that both partner's can't "see" what the partnership agreement is.

I think it's BBO's perspective that they want a stated definition of HCP and suit lengths when possible, even if GIB won't use that to make a precise interpretation. But I understand your point.
