Bug/hole in the bidding-db

Playing w gib, I held

AT643

Q3

AT94

 

Partner opened first hand 1, and the bidding started:

 

1 (1) 1 (P)

1 (2) ?

What to bid here?

With a human pd, I would most likely bid 3 to ask for stopper or secondary support.

 

But 3 was described as 4-card support, which makes this hand virtually impossible to bid sensibly.

Other options were:

2NT = nat invite.

3 = 4+ ♥, 4+ ♣, 9+ total points ///// (non-forcing, right?)

3 = forcing with 6+

Decent intermediate or better players are playing 'almost' all

 

low level doubles as card showing, support Xs or TO Xs.

 

 

A double of 2D should find you 3 card H support, partner showing

 

long clubs, bidding 2N or even passing with a suitable hand.

Forgot to mention, X was defined as "biddable diamonds" or something equiv, so too dangerous playing with Gib.

Are you sure you have the auction right? At a practice table, GIB is saying 3 at that point shows 4+ , 4+ , 9+ total points, which seems to describe your hand. (Though I agree GIB assumes a cue bid shows support far too often).

 

Yes, bidding is correct, and your description probably right -- my bad, typing from memory, sorry :(

But my experience (from all earlier robot-games) anyways means it's non-forcing, which seems risky with my 13hcp.

 

I noticed now, at another table, someone else actually opted for a death-defying 3D (showing 4sp!) and robot-North then responded 3NT!

So I would suspect it is just an erroneous description, then.

Gib really does NOT interpret 3D as 4+spades....

This is so weird... at yet another table someone opted for the 3C over 2D. Robot-North then responds 3S!

 

So if I show spade-support, it bids 3NT.

While if I show club-support, it rebids spades... :blink:

GIB has a general rule that cuebids of the opponent suit in otherwise undefined auctions show support for partner's last bid suit. Here I would double, playing with or without GIB. It says biddable diamonds, but he probably won't pass, and if he does I think there is a good chance that is best if you have no major suit fit.

Hi jdonn,

But why does Gib bid 3NT over 3D above, if it really shows 4sp support?
