I don't understand the usefulness of 2N showing 2-4 spades. If responder has support with limit raise values, he should make a limit raise so we don't end up in 2N with a 5-4 major fit.

Passed hand has options to express invite by using:

- 3 in the major with 4+ cards support and 10-12TP
- 1NT with 3 cards support and similar values.
- 2NT is last by priority and basically doesn't deny having support in major opening.

Probably it could be more convenient if shows 2-3 cards and not 2-4.

If those three bids are in priority order, wouldn't 2NT always show 2 spades with invitational values, never either 3 or 4 spades?

I agree with you. If 10-12 with 3s, GIB will bid 1nt then jump to 3s. (As he doesn't play drury.) If 4 spades, he will bid 3s. Under no case will he bid 2nt with 3 or 4 spades i think.

GIB claim to play "forcing 1nt" by passed hand. Since this is the case, in theory I think it should just bid *1*nt with these hands as human experts do (planning 2nt rebid next round if given chance). This allow opener, holding flat hand not going to accept 2nt invite, to pass the forcing NT and play a level lower. There is no advantage bid 2nt, since sometimes unlucky and 2nt goes down.

Basically GIB should probably be set never to bid this passed hand 2nt not in competition over major suit opener.
