The exact meanings of my 2♣ is a long suited or 5M+4m (hello convention).but GIB gave up 3nt,of course,4♥ was not good spot.

GIB assumes that your 2C is the way that it plays, which is Capelletti, showing a single unspecified suit. Not identical to your treatment but not much different. I don’t know how GIB interpret’s North 2D, but South’s 2S confirms Spade single suiter. in that context East seems to have clear 3N instead of 4C, but perhaps concerned about D suit if 2D is read as natural

When you play against GIB, you need to play the GIB bidding system if you expect your GIB opponents to compete on a somewhat rational basis. If you psyche against GIB, which you are in effect doing when you play a convention or treatment that isn't in GIB's system, don't expect GIB to understand your psyche.

Even though Lycier pysched a little bit- its still a one suited hand, GIBs shouldn't have had problem at all any placing the hand in 3NT. Its just the bid-on beyond sense part of its bidding programming that is the problem- prefer a minor to Non-trumps should rarely be a choice when you have good alround suit coverage especially in the competing suit (spades).

I'd like to see the explanations of several bids improved. 3♠ should deny the ability to bid 3N. 4♣ should certainly show more than "2-5"C, (yes, it's true that if the other suits area all limited to 2-3 cards, there must be 4-5C, but still...) and also deny the ability to bid 3N. If 4♣ shows a real club suit, 4♥ should deny the ability to support clubs since the West has pretty much already shown that he holds 4H.

It looks like Lycier edited some of the bidding descriptions, but I would guess that GIB interpreted the 2♦ bid as a real suit, rather than a preference bid, which makes a 2nd psyche as far as GIB is concerned. GIB was obviously worried about diamonds on this hand.
