Normally this means a hole in the bidding database. If GIB can't find a rule to tell it what to bid, it just passes.

It never let me play a fifth round of hearts. Presumably I shouldn't have gotten there, but still.

Just had this auction with GIB: 2♣-2♦ 2♥-3♥ 4♥ 2♥ shows 5+H, 19+ HCP, 23+ TP 3♥ shows 3+H, 5+ TP (stronger than a jump to 4♥ would've been) 4♥ limits GIB's hand to 23-26 TP GIB's hand was this: [hv=pc=n&n=sakqjhakj4da864c2]133|100[/hv] The hand could've easily been a disaster if I really had 3 hearts and, say, some spade length. Note that GIB's positive response to 2♣ require some suit quality (6+ using the 8421 point count). It's a difficult hand in standard, no doubt, but I don't feel GIB made the best choice among the alternatives. If it doesn't want to rebid 2NT with a small singleton, it could treat the spade suit as five cards so it could later show 5-4 in the majors, or open 1♦ and pray it won't get passed out. For completeness' sake, my hand was [hv=pc=n&s=s643hq8752d5cakq3]133|100[/hv] So it wasn't really difficult to bid the grand, but GIB got lucky. Another day my majors would be reversed and we'd end up in a silly contract.

I didn't notice the forum and made using the straightforward line. Were spades supposed to break 5-1 or something?

Presumably that would've shown the wrong number of keycards, as 4♦ was 6 keycard BW.

[edit] Oh, you mean CPU, a bot, not CPU, a concealed partnership understanding. Sorry.

Yes. Thanks. Can you explain the logic? Can't W and E be heavier for their actions leaving S with a standard TO double?

5♣ on the second round? Do you mean (1♠)-P-(1NT)-X (2♠)-5♣? Or only if S doubles after 3♣ by N on the first round?

I'm retarded too, then. This auction shows neither side was too happy about their club stopper. On a good day, their combined stopper is Txx opposite hope, at least in my club.

Can we still get a "withdraw comment" button?

Human thinking again. I could be off here BTW, since to GIB it must appear that either S or N psyched, there are only 7 HCPs unaccounted for and both showed 6+. I'm not sure in what order it distributes HCP in order to simulate hands. The point here is that if you psyche, you'll confuse GIB, and it will never catch on.

It actually does. This keeps coming up. If the auction tells GIB S must have the ♥K then both ♥A and ♥x are for 14 tricks, so it'll choose one of them randomly since they're equal.We're humans, so we can reason along the lines of "but the A is safer on the off-chance S doesn't have his bid". GIB doesn't work like that.

FYP

What others have said, plus it's possible to beat the system. As you've already noted, the average "advanced" player is better than the average "expert". There are other similar principles to discover. Moreover, after you kiss some frogs, you'll come across decent partners. You can add them as friends and after a while you'll have a small group of players you know you can have a good game with. Then, you can stop playing with randoms completely.

Most likely your 3♦ bid confused the bot and it was going for 2 down based on what it thought you had.

It's GIB's system, so 2♣ doesn't promise anything. 2♦ denies 3 hearts, extra length in spades and a stopper in clubs. I think with Qxx it would bid NT either instead of 2♣ or instead of 3♦.

Can't you just play something like Ogust/feature ask over 3-level preempts too?

3NT looks like it might take up a lot of bidding room after a 2♣ opening. How do you continue if opener has an unbalanced hand playable in two strains?

Close, GIB led the ♣J. I thought it was remarkably idiotic. You expect E to have 2-3 clubs with a shaky stopper. If you're going for club bonanza, ♣8 and hoping for a return via Qxx seems to be your best shot. I was wondering if I was resulting, looks like I was? Sitting opposite I had ♣ATxx and dummy had the doubleton ♣9, so ♣8 nets four club tricks and ♣H doesn't.

Matchpoints, all vul. [hv=pc=n&s=sqj97h764dt32ckj8&d=e&v=b&b=10&a=1d(3+)p1hp1s(can%20be%20balanced)p2c(FG)p2d(Min%2C%20no%203%21H)p3d(3+%21D)p3nppp]133|200[/hv] GIB system so standard-ish leads.

I agree with the second sentence, which is why my auction continues 5NT after 3♥. However, if 3♠ is natural for you, what is responder's forcing heart raise?

Don, what is 3♠ in your auction?

In GIBberish your first bid should be 2♥ to set a game force and show five hearts. Then you can bid 3♠ over his 2♠ and GIB will raise to 4, showing a minimum and leaving you guessing.

Was 2♦ game forcing? How many diamonds does it promise? Was 3♣ natural?

jjbrr, that's what I thought, too. You always want to open the bidding and end up in the par contract for your side if possible. Then I gave it more thought, and I think the next stage would turn the game into poker, i.e. try to goal the opponents into doubling a making contract or taking a phantom sac, etc. That's as far as my thinking's gotten me, though, that you'd frequently psyche or have several different meanings for the relay responses to throw opponents off.
