Is this based on simulation ? Explanation says 2 spades is 4+ and 3 spades is 3+
Why not 3 clubs directly ?

The second negative is a bad convention, which would create a lot of problems when responder holds clubs.

Isn't North good enough to bid direct 3♣ after 2♣ opening.

2♣ natural responses like 2♥/2♠/3♣/3♦ require some quality in the suit, like KQ or better and 8+TP.

It will be considered for improvement. In the particular case it seems it comes as simulation bid as forced but not finding suitable bid.

Bidding 2NT instead of 2H probably would have led to a smoother auction, but don't see why GIB has to blast 6S if it lied about its length.

2NT currently requires a balanced hand (all suits 2-5 cards). But we should probably make an exception to avoid bidding a 3-card suit in this case.
