I thought that, but that would have given south 5+ clubs. I gave the simulator the trump void hand, and a few hands with 5/5 S/C. My simulation still gives 60+% for the ruff.

I think I am missing something here, but why would you not give a ruff when all the Diamonds are known https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|,~~v3fakebot,~~v3fakebot,~~v3fakebot|md|1SAQJ973HJ6DJCK632,S6HKQT874DKTCA954,SHA953D976542CJT8,SKT8542H2DAQ83CQ7|sv|e|rh||ah|Board%203|mb|1S|an|Major%20suit%20opening%20--%205+%20!S;%2011-21%20HCP;%2012-22%20total%20points|mb|2H|an|Two-level%20overcall%20--%205+%20!H;%2010+%20HCP;%2011-18%20total%20points|mb|P|mb|2N|an|11-13%20HCP;%20stop%20in%20!S|mb|P|mb|4H|an|13+%20HCP;%20strong%20rebiddable%20!H;%2014-17%20total%20points|mb|P|mb|P|mb|P|pc|D5|pc|DQ|pc|DJ|pc|DT|pc|H2|pc|H6|pc|HK|pc|HA|pc|CJ|pc|CQ|pc|CK|pc|CA|pc|HQ|pc|H5|pc|S2|pc|HJ|pc|HT|pc|H3|pc|S4|pc|S3|pc|DK|pc|D2|pc|D3|pc|S7|pc|H7|pc|H9|pc|S5|pc|S9|pc|CT|pc|C7|pc|C2|pc|C5|pc|C8|pc|ST|pc|C3|pc|C4|pc|D9|pc|DA|pc|SJ|pc|S6|pc|D8|pc|C6|pc|C9|pc|D7|pc|S8|pc|SQ|pc|H8|pc|D6|pc|H4|pc|D4|pc|SK|pc|SA|

The "Free Acol Individual Daylong (MP)" tournament seems to disappear depending on which login I use. Other people I talk to have a similar issue when using specific accounts I can see the tournament if I use the Director account for my club, but today I cannot see it under my own account. Other people have reported the same issue and it always seems to be on their same account.

P-P-1N-X 2D-P-2H-3C P-3N-P-P X Let's assume for now that the 3C bid description is wrong and that the bid should be 17+HCP as per Acol. From that bidding, you would assume that the 3N bidder had 6-8 HCP and a stopper in H. So making game seems reasonable. So, it was a surprise when lefty doubled. It turns out that P has JTxxx-Jxx-xxx-xx. What I think is happening here is that lefty (Argine) knows that the description and implementation of the 3N bid is wrong. So, is this an example of Argine(West) fielding a psyche by Argine(North) https://tinyurl.com/2h4j8xg2

Is there a problem with the Acol room in the free dailies. I cannot see the room to play the free daily. Using my club login though, I can see the room.

This is an open question for the GiB developers... Should some hands be removed from a score where there are enough reports of the AI going AWOL? TL;DR; We all agree that the robots are only human and will get things wrong sometimes. Chances are that this will have a negative impact on your score and your sanity (see any post about Argine!) If we consider 2 types of error. One where the AI has been duped (for example where you upgrade a hand and it counts the points wrong). The other is where the programming database is wrong (Argine) or the AI blunders (Argine and occasionally GiB) In the second case, if enough people who played the hand reported it, could it be removed from the general score. Even if enough people did not report it maybe anything where 1/2 the scores are -7 down could be removed.

I would whole heartedly disagree with the "bid very well" comment. Playing in the free daily, Argine has a WTF ratio of about 1 in 8 hands. Anything involving a Q bid is going to be a disaster. The definitions are way off for too many sequences. However worst of all is the hand valuation. In response to a 1S opener, both of these were "worth" 3S... Jxxx-xx-Ax-xxxxx AQxxx-x-KJxx-xx

Without going into specific hands, the GiB Acol bidding system has several fundamental flaws. I’m not sure that all the problems are down to the descriptions of the bids, but something really basic is going wrong. From worst first Forcing bids being passed regularly Inability to value distributional hands in response to NT openings Bidding to game after intervention and not bidding the same game without intervention NB the intervention is totally irrelevant in most cases Frequent discard issues when the distribution is 100% known Picking a 50 line when there is a 100% line. This may be down to it’s understanding of the bidding/play

I have a hand in my hand history that I would like to put in a BBO Forum post. I can export the tinyurl, but how do I save the hand in a LIN file so I can get it on the forum?

Another situation where Gib "knows" that it is making exactly no matter what card it plays. Gib does not use any kind of fuzzy logic. You have shown 55?? and therefore must have it. Introducing fuzzy logic into a bidding/play system is possible but I think beyond the current design of Gib. In fact, I have implemented a simple system that uses FL for the last few tricks and this is currently beating Gib at about 57% over 10000 hands.

It's not a bad contract a priori. I'd be happy in this at IMPS. What is strange is the 3H is forcing. The choice of force or pass. Not my cup of tea I'm afraid.

High-level bidding is particularly difficult for robots - this sequence may not be fully described in the bidding DB. It is also possible that Gib is passing the buck. It "knows" that you have a fit, and therefore it "knows" that you will do the right thing and bid 4S.

X to show a strong hand (and TOX) is reasonably common convention. What has gone wrong here is the Total Point valuation causing Gib to overvalue the hand. TPV is a common failing of the Gib bidding system where shortages and solo honours can be overvalued. In addition, the use of TPV before you have found a fit can cause even wilder point valuation as you are effectively giving value to shortage before you know that the shortage can be fully efficient. The most common effect of the failure of TPV is in mismatched NT contracts - high TPV but low trick-taking possibilities.

The first Pinned topic on this forum quotes. "For example, GIB never miscounts a suit. It never misses a spot card. It never forgets its own system. It never fails to notice… well, anything. Overall, GIB plays better than the average player on BBO – in fact, this has been proven, as when GIB plays in BBO tournaments that humans played in as a test, it consistently performs well above average." I have seen many cases where this is not true, or needs caveating. "GIB never miscounts a suit" Yes, it does. In the case where the end-play needs a count of the partners suit, it can get the discards wrong" "It never misses a spot card." Again, that is true, but in defence it does not always play the obvious card for partner. For example, it "knows" that its has QJT7 and that all cards are "equivalent". However, it may play the 7 making it hard/impossible to catch this. Also, it can miss the spots if you false card "It never forgets its own system" O yes it does, and with a regular (~10%) occurrence. Frequently it makes bids far outside of the HCP/TP in the hand. Even worse, it can frequently q-bid cards that it does not have - usually the 2nd q-bid. So, the question is, how to avoid these errors, and what to do when it happens. As far as I can tell - the only solution is really, really reign in your competitive bids and this spoils the game somewhat.

This is the perfect answer, thank you. I should have stated that the game was online so the 2D self-alert was late and came after I had bid, and at the same time that the 2H bid was made. It was at this point that I called the Director (ASAP). So 21B1a applies exactly, but how should the director have handled it? FYI. With the correct alert, I pass and bid 2N (leb) over the 2H bid. With the director encouraging us to continue (and tell him if we were damaged), I did not have the chance to take the bid back. TBH also, I direct online on the EBU occasionally, and I might have made the same decision. Personally I would give a score/Av or score/Av+. However, I was not looking for an adjustment, rather to learn what went wrong :)

The agreement was muddied by the late alert, and that is the issue. 1N-(X)-2D-(X) 2H? If the 2D is natural, then any bid is GF, X would be pens for H's. We have points for game, we either punish them or take the game. Over 1N-(X)-2D-P with 2D alerted 2H-(P)-P-? I now have Lebensohl to push to game or partscore. The problem is that the information about the 2D bid came too late and left us in a muddle.

... timing Opps playing a Weak NT. X is penalties (16+ points) LHO P RHO ME 1N X 2D D 2H PPP After the 2D bid, I pause for a few seconds (no alert) so I doubled. LHO also paused for a few seconds. At the same time that LHO bid 2H, the 2D was alerted (as a transfer) When it comes back to me, I am now stuck for a bid. As I have already X'd, any bid by me would be GF, including 2N. I have a hand that would normally pass, then bid 2n(Leb) over the 2H transfer (intending to bid 3D-NF over 3C). I do not have a hand that that can now compete below game (as I said, any bid is GF, even 3D) Director was in an awkward situation but suggested that we continue and get back if there was any damage. (18%) for us and no adjustment as he said that I could have bid 3D (the late alert had muddied the waters for me). So, was this fair, or would an adjustment of 18%/Av be fairer. NB I'm not looking for an adjustment, just opinions on the decision. FYI I had AJT-8-JTxxx-Qxxx Too little for GF

Hi Barmar, I see your point and might I humbly suggest a reasonable work around. As I see it, the TCR is used to limit "runners" from certain games - which is an entirely reasonable thing to do. The limit on calculating the TCR means that infrequent players such as myself may be limited in the competitions that they can enter. Would it seem reasonable to add another criteria of "unrated". This would in effect be a default TCR of 100%. The fix that I suggest is that this is the default after a user has had their account for a set period of time - say 6 months to 2 years. This would stop users creating new accounts on the day, and would also let infrequent players compete. An added bonus would be to encourage more players to compete in country sanctioned events where the user is tied to the national user. E.g. My main user (non-director) is tied to my EBU account and I would like to complete in EBU events but currently cannot due to the "runners" restriction.

I have a TCR of "Unknown", and this seems to block me from entering also. If the measure is over the last 60 days, then am I being penalized for not playing in enough tournaments? I can understand the restriction for new players (to stop people just creating new accounts), but for players who have had an account for many many years, this is restricting me even getting a TCR as I cannot enter with my regular partner.

First a RANT... Upon entering a free (sparkling) tourney, I was rejected by the system as my TCR was too low. I have a BCR of 87% and 94% but my TCR for both users is "unknown" For user 1 (my normal user), my BCR was 87%, for user 2 (my director login) it was 94%. However, I cannot see why the rating is so low and my TCR is unknown... For user 1, I have played in over 80+ Daylongs/Instant tournaments in the last few months. I dropped 1 of them because I lost connection and another because I lost time. For user 2, I have only ever played as a sub in a the EBU tournaments and cannot recall any other form of play. In fact it has been about a year since I last used this user. So this makes me think that my play in the casual room has been taken into account! Given that these rooms are a total wild-west, adjusting the TCR for this seems ridiculous. I may leave early as a dummy but I rarely leave as declarer. If I fail to finish a robot only daylong, i'm the only one that is impacted by this (loss of BBO$) so why would this count to my TCR? Now my questions How do the various rooms affect the TCR. How does the TCR get calculated How do I get it back up or reset if possible. Is the min TCR available on the description of the tournament. Can we see how the TCR is measured? If I have an "unknown TCR" how do I enter tournaments I tried this but I was not 100% clear. https://www.bridgebase.com/help/v2help/completion_rates.html#:~:text=Tournament%20Completion%20Rate%20%28TCR%29%20is%20an%20automatically%20computed,basis%2C%20and%20include%20all%20tournaments%20played%20on%20BBO.

So, this is the tricky bit. The system is 4Cm, Weak NT, with standard openings at level 1. So, on the face of it, it is Acol based. The 2 bids are Muidberg (2C=Str, 2D=Multi, 2M=Mm inter, 2N=mm weak). This structure is not that uncommon in an Acol club. However, all responses a 1C opener are artificial with transfers and relay responses 1C -1D/H Transfer to H/S -1S Transfer to D or 6-9Bal -1N Both majors or 10-12Bal -2C Inverted -2D Both majors weak -2M Weak major 6+ suit. -2N GF Bal I take your points though about not being fair. We can tone the system down to play in the Acol room. So that might work at least in part for all parties. In general we play in open competitions also and I've always thought the standard in the Acol club to be good enough so that people have at least been exposed to a system or 2.

Thank you for the BBOalert. I had asked this in another post so this answers that question.

As we play in clubs/tournaments in the UK most of our opponents play Acol. This is the reason for favouring the Acol room. The strength of the competition is not a major issue as we mostly do it to test the system against Acol players.

So, I could put this in the systems forum but the question is a little more broad. I play regularly in the Acol/main rooms. When I play with my regular (tournament partner), we get abuse for playing a system that is too complicated. The system is based on Acol+Multis with all the openings as per normal. However the initial responses may be artificial/relays. We want to continue to play in the Acol room as we play in England but we are getting a lot of abuse/complaints about the complexity of the system. Are we being to aggressive with the system, or are the complaints unwarranted. NB We always alert the bids but even Advanced+ players have been known to complain/abuse us.

What has happened to the system where you could enter an automatic description that would be alerted/displayed when you made a bid with a custom convention card. I have started to play with a regular p and our system is fairly complicated and having to enter the explanations each time is really slowing the game down. Especially when people do not understand the short description.
