This hand was played in "Just Play Bridge", so I have no hand record.

I open 1N, CHO bids 2, doubled to my right.
I bid 2, CHO bids 2, explained as 9HCP
I bid 2N, CHO bids 3, explained as 4+D, 9HCP

CHO holds xxxx, AKJ, Jxxx, xx.

Seems to me that CHO invited game, I declined the invitation, and CHO refused to accept the rejection.

I think it makes sense to bid like this on:

AKxx x xxxxxx xx

i.e., you're fairly sure 3D will play better than 2N.

4+D seems like nonsense (5+ is OK, I just gave 6 diamonds for the example hand for clarity).
... and I can prove it with my usual, flawless logic.

Hmmm... I like your example, but I'm having a hard time figuring out what the bidding rules would be. Should the descriptions of 2 and 3 include "4+", expecting GIB to invite with 2N instead of 2 with only three spades?

Oh 2S always shows 4 spades, I thought. I have never seen GIB make this bid without 4 spades, at least. It's an alerting fail but correct bid.

Yes, that's how Gib bids like, since 1NT-2NT is transfer to clubs.
Actually, 2 shows exactly 4 spades (not 4+) since it would rather start with 2 transfer when holding 5+spades and no suit.

So looks like a fault in bidding-db. 3 should be defined as at least 5+, if not 6+.

I'm just thinking, though... with such a fat suit -- esp. after the X of 2 -- the robot might figure 3 on 4-4 or 3 on 4-3 would be a better play than 2NT,
and expects you to either pass with 4 diamonds or correct to 3 ?
