Most players would be better off passing balanced 8 counts facing a 15-17 HCP 1NT opening. Now, if you have one or two major suits, that might be different, depending on whether you have a suit oriented 8 count (more aces and kings, less queens and jacks - especially in short suits).
Then you comment about 9's and 10's. I am reasonably sure that GIB does not pass 9 counts, and it certainly does not pass 10 counts. So I don't understand the second part of your question.

That said, I disagree. I pass flat 8 HCP points routinely opposite a 15-17 NT, even Vul at IMP's. I got lots of extra plus scores to make up for the occasional missed game. But yes, with some great spot cards I may upgrade.

Good point about 9's and 10's being spot cards. So, what is being said is that with 8 HCP and some 9's and 10's, a hand might be worth an invite. I don't think anyone would argue that. But what you are doing is judging that your 8 HCP hand is worth more than most 8 HCP hands. If so, feel free to invite. Apparently, GIB is programmed not to invite on 8 HCP hands. I don't know if GIB counts anything for additional 9's and 10's.
I am always quite wary when GIB invites anything. It is far too aggressive in inviting slams. As for games, I find that its invites are OK, but its acceptances of invites are too aggressive.

You continue to misread OP's comment about spot cards; he's talking about spot cards in opener's hand, not in responder's hand, making opener a "good 17" or a "good 16".

You'll end up playing in a weak 4-3 fit going down, where 1NT makes. That hand is way too good for desperation measures.

Thank you for your reply.
If you are correct, then the ACBL standard teaching manual ("Bidding in the 21st Century", written by Audrey Grant in 1986 and updated in 2006) must be wrong. The ACBL manual recommends making an invitational bid when you have 8 or 9 points and your partner opens with a strong 1 NT.

If your policy is "Pass unless max", then inviting on 8 has more appeal than if your policy is "accept unless min". There are policies between those extremes, of course.

What is the range of the 1NT opening in that book? Is it 16-18?

I guess the GIB is a bossy player. It wants to make the final decision. One other example is that the GIB often changes my 3 NT bid to 4 of the majors of 5 of the minors. Often I am forced to play 4 spades or 4 heart with only 7 trumps and the result is terrible. The GIB knows we only have 7 trumps because I did not open the major and he has only 3 trump cards. My human partners almost never change my 3 NT bid.

Yeah be sure if it is using 16-18 or 15-17 range. A lot of beginner books are saying stayman/invite with 8 but based on old style 16-18, with 15-17 flat 8 is too aggressive. Yes partner will accept & game will make sometimes, but if you balance those out with all the times you go down in 3nt, and down in 2nt, it's a losing proposition to invite game.
Complaining about pulling 3nt to 4M on Moysian 4-3 fits is a much more common and valid complaint about the GIBs than worrying about them passing 1nt on 8 which is totally defensible. If you run into the 4-3M fits, just post the hand here, and hopefully georgi or someone else at BBO will eventually get around to fixing the auction.
