Is d a GIB or human player?

Because 3N is pick a game between 4♠ and 3N, as 3N is promising 3rd♠

Isn't 3NT a spade raise in GIB's system?

Not according to either GIB's convention card or the system notes.

Edit: d is a human player.

strange. When I played an ACBL robot matchpoint game, 3NT was "hover alerted" as a balanced game choice.

Then I guess the purpose of this thread is to alert the developers that the convention card and system notes should be corrected to reflect GIB's actual play.

Here's what GIB says about 3NT over 1♥: Balanced, choice of games. -- 3-4 C; 3-4 D; 3 H; 3-4 S; 13-15 total points

Well clearly "d" cannot bid either.

There's still a problem with GIB's bidding. Since its definition of 3NT allows for 4 cards in the other major, its correct rebid with 5-5 or 5=4 majors should be 4♥.

Shouldn't that be a cuebid investigating slam?

As others have said, 3NT shows some 4333, so West is right to pull. I believe that a change of suit is a help suit slam try.

Yes, Any other suit beside the opened major would be slam investigation, not just pass/correct me.
Natural, but strong.
