4nt showed blackwood (♦),my answer is 5♣ to show zero or three keycards,and GIB rebid 5♦ to show signoff.Now I think I should "repect" GIB,so I pass.I think GIB regarded my 5♣ as zero key card,however perhaps GIB forgot my strong opening.

Given the explanations of GIB's bidding, the hands when GIB doesn't have a red ace are pretty rare. GIB logic isn't very good at figuring out your total keycards from the bidding when you show 0-3 or 1-4, so you should go ahead and bid a slam which should make a very high percentage of the time.

That's not a great answer though, because let's say he also had the ♥A, he can't raise GIB's pass of 5♦ to slam.

You want a great answer when you have a partner that will pass 5♦ OK, if diamonds are trump, you could be screwed. But if hearts or spades are trump and GIB signs off at 5M, you can bid a small slam.

georgi said he's going to teach GIB to raise 5 to 6 if the human signs off opposite the "0 or 3" response, maybe he can do something here as well.

GIB could have had 6HCP, 3 distribution points and no ace- its been known to do blackwood without a keycard in its hand.

Georgi can program the human to keep bidding? He's good!

You rebid a nonforcing 2NT with a 26 count and then complain about GIB's bidding?

FWIW, I think that you'd be a lot happier if you learned that the point of robot tournaments is to do as well as possible partnering GIB, not to achieve some mythical par bidding sequence.

[Antrax]

hrothgar, it's GIBberish that's the problem. Most humans wouldn't consider a 3NT opening, which is what GIB expects S to do with a 25-26 balanced. Once you go 2♣, all NT rebids show the same thing I believe.
