2.) Having asked the first question, HOW can West pass the X, when partner easily could have a 7-8 HCP hand??? It looks to me like a GIB Basic issue to be fair, but it shouldn't be an issue.
3.) While I prefer on this hand for GIB to rebid 1NT, does it take suit quality into account when deciding between 2♣ and 1NT?
4.) Why doesn't GIB lead my suit back?
5.) Why does GIB still play Inverted Minors by a passed hand?
6.) Why is GIB bidding a 3-card Spade suit here?
