(GIB) Unusual 1NT sould only be when opponents have bid 2 suits

[ThorvaldAagaard]

There is no description of this agreement on the website

1N seems to be other minor + a major

T/O Double is more important than unusual 1N

Do we want to specifically play 1NT as 4-5 with 4 in the higher suit? Jack plays this and either doubles or overcalls with the other shape. I (IAN) tried it for a while and it seemed sensible.

Like a Raptor 1NT?

[ThorvaldAagaard]

Perhaps but 1: Unpassed hand always bids 1N Natural 2: D is 2-suited (or strong bal) 3: 1N From passed hand is 2-suited, but only 4-card major. With only 4-4 double is probably best anyway 4: with 5-5 2N should be preferred if losers allow it. 5: With 2 many losers and 5-5 and to weak to double 1N as a preemptive bid could be OK

[ThorvaldAagaard]

This is still a problem.

Usual 1NT is only when both opponents have bid as written on the website

If 1N is minors it is a bad bid with 4-card spades - it is a perfect T/O D of 1H

The south hand with 4333, should just bid 2H After 2C there is no clear description of 2D. Is it responding to Drury?

According to the documentation Unusual 1NT is when both opponents have bid. But here BBA is using it on a passed hand.

That is fine for me, but it is not how GIB defines it.

So we need the documentation updated - and it is probably another convention

Fine, now we just need a way to deselect the second option
