The description of the 2♠ bid was 5+♣; biddable spades, 18-21 HCP, etc.
The description of the 3♥ bid was the same with 3+♥ added.
The description of the 5N bid was Query kings. Have all keycards.
The description of the 6♥ bid was King of H; 5+♣; 3+♥; 18-21 HCP; biddable ♠; ♣Q; ♥K; 19-22 total points
My questions isn't so much why didn't GIB bid 7♥ but why did it bid 5N in the first place if it wasn't going to use the information it gained?
