1♦-(1♥)-dbl-(p);
3nt (1) - (p) - 4♣(2)??

GIB holds ♠QT82♣J5♦J♣AJT985

(1) shows 3+D, 5-h, 5- sp, 20-21 HCP
I think maybe lack of constraint on spades leads this GIB to pull to 4♣?
should be something like 4+D, 3-SP IMO.

(2) shows only 4+C, 4 SP, 7+. Should show 5+ clubs, slam try IMO?

Furthermore, 3nt bidder can't pull back to 4nt since it's "blackwood". Can
we have a rule where if your previous bid was 3nt, 4nt is not blackwood?

3nt +4, 4c + 4, 5c should be -1 but made on GIB's bad def.
