♠Txxxx ♥Kx ♦K9x ♣KTx

After an uncontested 1♥-1♠-3♦, GIB rebid 3♠.

________

I thought this was an impossible auction:

1♣-P-1♦-1♠
2♥-All pass

Shouldn't opener's reverse, even in a contested auction, be a one round force?

actually this involves with one of the biggest problems of gib bidding. Gib simply hates 3NT. So whenever possible, Gib wouldn't bid 3NT. For example, after a 2/1 gf sequence, a latter 3NT bid would show 13 or more HCP in gib's system, which is a huge nonsense IMO. Here, since gib hates 3NT, it would bid 3S instead. The new rule should be that
1 in a gf sequence, 3NT doesn't require any extra.
2 gib should never pull partner's 3NT without a good reason, for example, slam possibilities, blabla.
3 when 3NT is a possible good spot, gib should bid it instead of suits.

hammans_rule() {
bid(3NT);

Actually, as confirmed by a thread in the B/I Forum, 3♥ is normal with the first hand.
