Unfortunately,
1♠-(P)-1N-(2♥); X = "5+ ♠; 15-21 HCP; biddable ♥; 22- total points",
which is totally unplayable.
Has a human come up with that explanation or is it somehow auto-generated?
It's not unplayable. It's a penalty double. Not uncommon after a NT bid. If partner has this hand you will kill 2
♥.Takeout is more flexible. Plus Gib would pull the penalty when it's right and leave it when it's wrong!
The problem is Gib bid 2N without a stopper. Probably because the 3-bids are defined as weak and Gib has the points to invite.
Maybe a double Gib should be defined as takeout and is also defined as penalty.
