Yes, this hand will look familiar. What is NorthGIB trying to accomplish here? 2♠ is explained as "Other major; 9- HCP; 9+ total points", completely avoiding mentioning anything about distribution.

probably trying to punish your 1NT opening ;-)

1NT was odd; 2S was silly (surely needs 4 for that); 4S sillier still (surely needs 4 for that).

Interesting there's no "4+ spades" mentioned on the description of 2S - if it is the "other major" that's what you'd expect, right? Edit: also what is this "9- HCP" and "9+ total points"... seems contradictory, and depending on the method 2S should either be like 5- HCP, to play, or unlimited and F1.

Yes, I agree that 1NT was odd and possibly deserving of punishment; it wasn't me who made the bid. However, I'm more interested in what GIB does than in what other players do to amuse themselves.

GIB would hardly be the first player to end up in a 3-3 fit because both players thought they had the right kind of hand to be the 3-card hand in a Moysian.

GIB's system notes say that over 2H, 2S is invitational showing 4 spades whereas 2N would be invitational denying 4 spades. So, I'm asking whether (a) there's something in GIB's coding that caused him to bid erroneously bid 2S, or (b) GIB ran a simulation and determined that 2S was more likely to lead to the best contract than 2N was. If (b), maybe this is a sequence I should consider in the future when I hold a hand similar to North's...
