You see the bidding. GIB's 3N bid definition said "partial stop in ♥ "

See "tinyurl..." link if you want to see the whole thing, including definitions etc, but try to imagine what you'd do with this hand after reading the definition and seeing only your hand.

I thought about bidding 4C before giving up, but didn't see what good it would do me, even if GIB cue bid hearts. Could a partial stopper possibly include the ace or a void?

Anyway, most of the field bid 6 anyway.

From practical experience, "partial stop" means partial stop or better. I would bid 4♦ over 3NT to show a void, assuming that's what it shows in Gibberish.

[steve2005]

Loser count says- you have 4 losers partner should have a most 7.
This means 5-level should be safe and if partner has extras 6 could be on. Partner doesn't encourage with 3N but still is showing values

North bidding NT is ridiculous it has 5 trump. just cue bid A♥ and see what happens

Jacoby 2NT asks for shortness, singleton or void, so 3D showed that.

I hate to be always on the defense, but I did think this through. I considered possibility of king, but that would best case. An ace just can't be a partial stopper. It's a first round stop unless it gets ruffed. I considered 4C after 3NT, but what good would that do, even if GIB bid 4H? Partial stop says no ace of of hearts.
But lets say "partial stop or better" could include the ace, I'd still want more assurance than that holding 3 small hearts.

Anyway, I wanted it to be pointed out if this is a place where programmers look at the posts. We all know that definitions need a lot of work, and this is just one more to add to the pile. There's no doubt it is not as easy to fix as we sometimes think it should be. If it was it would have been done. I don't think it's overstating it to say that the person who invented GIB is a genius.

[iandayre]

The system bid over 2NT is 4C, showing a good 5 card suit. If GIB bids 4H, you can't miss slam.

Hi there-

I'm looking at Jacoby 2N link and it says 3♦ Singleton or void in diamonds. It's the 2nd line after 3C.

BUT...as I look farther down the page it says 4♣ = 5+ clubs!" I'm just glad that my passing didn't ruin a good game; although I would have been in positive territory if not for that one. It was IMPS.

I had it in my head that showing singleton or void was first priority after Jacoby 2NT resp, but it's coming back to me now (thanks to you) that there is the other option with 2nd suit. I took a 20-year break before starting back playing earlier this year. However, you'd think it would have come up during the zillion robot tournaments I've played last few months, but if it did I don't remember it.

You should come around more.

Not sure of HCP if 4C. This time GIBBO was almost right. Showed club stopper, h stopper while upward bound. For all it knows you have shapely 10+ HCP (which it opens on all the time). So it is being descriptive and showing a balanced hand. ok, ok it does have 5S. Not every 5-5 spade fit will make. Given 3NT is showing this, I (very sorry) assign 100% blame to 1S opener. I rarely agree with GIBBy. 4D or even 4C is kosher here.

Thanks for confirming what I just acknowledged. I know that I can always count on you to set me straight. I will refrain from commenting on any further posts of yours, since it is clear that you resent them. However, I might comment on what some of the people who respond to your posts have to say, since you are probably the most active poster here.

I’ll take the blame on this one, since I didn’t make the optimum call, and GIB has a tough job. However, my reasoning was not ridiculous. Whether first response to Jacoby 2NT was 3D or 4C, north held the exact same hand that included the ace of hearts. Yet on one sequence the definition says he doesn’t have it, and on the other it says he does. The ace of hearts is not a partial stopper.

That said, I now know that GIB will let you know that he holds the ace of hearts if you make the optimum call of 4C, and I’m good with that. The robots have tough job, and 4C happens to be the best call in this case, since it shows shortness somewhere and the second suit all in one bid. With a human you could show the ace of hearts either way, e.g. 1S-2N-3D-3N-4C-4H; or 1S-2N-4C-4H and probably be o.k.

While you might become an advanced player someday, you are not there now. I wasn’t trying to put you down when I said that you could improve your game by entering some tournaments, rather than always playing money bridge against a single opponent. The way I understand it, you are matched with a player of equal rank when playing for money. In the MP and IMP tournaments you are competing with players of all levels, including many of the heavy hitters with thousands of master points. In a single session you can compare your actions with 20-30, and often 40 players or more in a single session.

[Stephen Tu]

I don't think it's reasonable to equate "promises a partial stopper" as "denies a full stopper". Only in a auction where full stopper denied in a suit then 3nt bid later can you make that inference.

Partial stopper means at least a partial stopper as johnu explained, not at most a partial stopper.

You are way more than min and have all the trump honors, can't sign off.

Lesson learned. I thought it did.

"You are way more than min and have all the trump honors, can't sign off."

True, if I believe that the possibility of ace of hearts still existed at the time I made the decision. I did not.

GUARD (STOPPER). An honor holding in a suit that will or may prevent the opponents from running the suit.

A guard may be:

(1) Positive: A, K-Q, Q-J-10, J-10-9-8, 10-9-8-7-6.

(2) Probable: K-J-x, K-10-x, Q-J-x.

(3) Possible: Q-x-x, J-9-x-x.

(4) Positional: K-x.

(5) Partial: K, Q-x, J-x-x, 10-x-x-x.

Thank you, vrock. You made my day.

[Stephen Tu]

Yes that's the terminology, but you have to use some common sense. Do you think it's practical to put super long descriptions like partial stopper or better and three times once for each suit? Do you really think partner has gf bid missing all trump honors, but also denies a full stop in all three outside suits also? That would give him a 5 count if you took partial stopper completely literally.

I understand and have an appreciation for what GIB can do, and how complicated it must be to sync the definitions with the thousands of hands it could encounter.

I was defending myself from statements like this:

"don't think it's reasonable to equate "promises a partial stopper" as "denies a full stopper".

All you'd need is a mini-version of: "5)Partial: K, Q-x, J-x-x, 10-x-x-x." You could compress it to less than half that size--I'd even settle for "no ace"

Talk about being unreasonable...geesh. Take a Bridgwinners poll asking if a partial stopper could contain the ace. I think you know what the answer would be, and it would probably be unanimous.

I find descriptions too long-winded as well.

If the description of 3NT was posted to Bridgewinners, I agree it would be unanimous - in favour of Stephen Tu's explanation. I'm afraid it's pretty obvious that such a 3NT bid describes a minimum amount of stoppers in each suit; why would you ever want a 3NT bid to deny a full stopper in every suit?

[Stephen Tu]

Your position here is totally absurd. If you polled, and asked the question "partner is first to make a NT bid which he wrote in the system notes shows partial stoppers in the unbid suits. Do you assume this definition means he denies a full stop in any of the unbid suits, and has exactly partial stoppers, not full?", people would say no, you're crazy. I mean who the hell designs a system where you are supposed to bid NT with Qxx Jxx in the unbid suits, but are not allowed to bid NT with AQx KJx in those suits?? This just doesn't exist in normal bridge. It makes no sense. 1S-2h-2nt. I play that this shows at least partial stoppers in both minors. I don't particularly want to bid 2s on Jxxxx Ax Qxx AKx, just because Qxx is only a partial stop, I don't want define 2nt as full stop both minors. But now by your rules I can't bid 2nt because I actually have a full (double!) stop in clubs, and 2nt is partial stop in both minors??? Because I have partner that assumes shows partial stop unbids denies better than partial stop in unbids?


Think about what you are saying. You are saying if it says partial stop all suits, that it means exactly partial stop no more. That means the best it can have in any of the suits is Qxx. Because anything stronger is a full stopper the way most people define it, when that person bids NT first.. So that means you have constrained partner to have bid a GF 2nt raise on Txxx Qxx Qxx Jxx.

Don't quite know if I posted the one where they supported diamonds, we had agreed on a major and headed to game and GIBBO in all its glory on Qx in diamonds bid 3NT showing a stopper in D. Knowing it tends to do that when trumps are weak or HCP count might be lower than expected, I passed. down 2 or 3 vulnerable.

But I agree with what you wrote Steve.

Peace, you guys. I’m pretty sure that if we were talking to each other in person, you would understand what I’m trying to say and I would understand you. I seriously doubt that we are as far apart as it appears.

For example, you and Merriman are filling out a card at an offline club. You ask him what he promises for a certain bid and he answers, “partial stopper”. Would you think it could possibly include the ace? That was what I meant about the taking a poll—the raw term “partial stopper” without considering GIB, writing programs, or any of that stuff.

“Your position here is totally absurd…”
Yes, that would be absurd if it was what I thought. Also, what I post here almost always addresses problems I've run into with GIB, which are relatively few considering the number of tournaments I play--600 in less than 3 months. The great majority of the time my biggest problems are figuring how to bid and play the endless stream of tough hands that the robot tournaments dish out. I should probably spend more time studying and play fewer tournaments.

I have more to say but am too tired now. I was confused by definitions and tying it in with in with common sense bridge...continued Mon...

I was making more out of than it was--like some special GIB treatment rather than what he actually had--a no trumpish hand with spade support and wasted diamond values. The 5th spade was a mild surprise. In many cases my problem is more related to my not having a good understanding of how they work as the definitions themselves. The majority of them the time I just look at what it says and don't go any deeper than that.

If I would have just bid it without looking at definition I would have been o.k. although I agree 100% that 4C response to Jacoby 2NT is the correct bid. It was how I played it in past but forgot about it. It could have gone 1S-2NT-3D-3NT-4C-4H and on to 6.
However, I ran my cursor over the 3N bid and when the box opened the cursor landed squarely on "Partial stopper:♥" and it threw me off track. I took at face value rather than a blanket description that would be applied to any NT hand.

Anyway, I don't fully understand how the definitions work and have more questions. However, I need to look at a few more hand records before bringing them up.
