I was playing the robots and opened with 1, raised by robot-ptr to 2, and had xxx in and an invitational hand so I bid 2NT as a help-suit / long-suit game-try. Robot had 8HCP (incl. a Jx), Qxxx in and bid 4 anyway. What explains this?

Somehow the record reset and so I don't have the exact hands available, but IIRC it was something like:

N (robot)
Q8xx
Qxx
Jx
Kxxx

S (me)

9xx
AKJ9x
Kx
QJTx

The south hand has 14 cards. As for accepting the game try, 2NT shows 3-11 8421 points in spades, and so it probably felt that Qxxx was good enough given you "must" have an honor.

Even if I was a bit too weak to make a game-try bid, the robot doesn't know that.

Also, I think I included one too many . So

♠9xx
♥AKJ9x
♦Kx
♣QJx, maybe QJ9 or QJ8. Something that seemed sequencey and was thick when matched with robot's clubs.

As manudude03 implied, GIB defines the game try as having a queen or better. So using it on xxx will never work well.

Yes.

Qxx or better = help suit for game try.
XXX = weak suit
Gib doesn't play weak suit for game try.

8 hcp is better than the minimum, so not unreasonable to accept.
Here, of course, south is too weak to invite.

Thanks, all. What is the logic behind needing Qxx or better in a help-suit? I guess if you're playing two-way game tries, and your biggest vulnerability is a xxx or xxxx suit, then you care most about partner having shortness in that suit, so you bid 2 or 2NT to ask for their shortness.
