661_Pete Posted January 11, 2017 Report Share Posted January 11, 2017 This is a constant nuisance for those of us who take our participation in BBO reasonably seriously (monitor our IMP average and strive to improve it, I mean). Not because of such a player turning up at our table. After all, for misbehaviour of that kind they would surely be ejected by any responsible host. Instead because of the distorting effect they can have on other tables which have played the same hand. I've noticed this sort of thing several times, and as it happens there was one in today's play, although this time it worked to my partner's and my advantage, so I suppose I shouldn't be complaining! Nevertheless, if we gain, our opponents lose, and I don't like to score against decent opponents (good players both) on these terms. I'd rather score because of honest play. Sitting East-West, we were in a good 3NT contract, well bid and made. mostly thanks to my partner's good play ;) , and earned a top on the board. What surprised me was that we netted over +11 IMPs on the hand, more than you would expect for a simple 3NT, so I looked at the traveller. And sure enough, on one table another E-W pair had gone 1NT-7NT, totally unwarranted and presumably out of bloody-mindedness. Whatever, this little excursion bagged that pair -8.5 IMPs and pushed all the other E-W scores up by a substantial margin. This is not as bad as the alleged cheating which lots of BBO players have been complaining of, of late. But it is still annoying. Should there be zero-tolerance of that sort of behaviour? After all, it is easy enough to spot and report - unlike cheating. Quote Link to comment Share on other sites More sharing options...

If you actually care about this, simply rescore the hand yourself and mentally award yourself the score that you actually deserve.If you don't care, all the better. You don't need to do anything.

GrahamJson Posted January 13, 2017 Report Share Posted January 13, 2017 A simple remedy, at least for the scoring aspect, it for BBO to adopt Butler scoring. In this the top and bottom scores for a board are ignored and the remainder are averaged. This eliminates bias caused by one extreme score. I believe that if the board is played many times the top and bottom two scores are not used when calculating the average. http://www.bridgewebs.com/helensburgh/page14.html Quote Link to comment Share on other sites More sharing options...
mycroft Posted January 13, 2017 Report Share Posted January 13, 2017 There are massive issues with Butler scoring:the datum (that average you are talking about) is almost never a bridge score, and the IMP scale relies on bridge scores for a lot of its boundaries (never mind that there's no spot on the IMP table for a 43 difference, frex). This means unrealistic comparisons. It also means that a change in the score in your benefit (from -140 to -110, for instance) may in fact *reduce* your IMP score, if it changes the datum sufficiently (there's a well known example from a high level cash-prize tournament).compared to the "blow off" 7NTxx hands, the number of hands where an extreme score is actually valid (Oh, I'm the only one playing Precision, so I'm the only one that can find the grand; my opponent refuses to sit still and took the -2300 sac of our 6♠ contract; Cappelletti mixup leads to 3♥-4 on the 4-1 fit or 5♦x-4 if bidder panics) means that we shouldn't magically "throw them out". Sure, *they* get their result; but I get an automatically better score than I would because I don't have to score against the Precision grand bidders.because of the nature of throwing the scores out, the total result on a board/session is never zero. If you happen to be on the side that averages -23/18 board session, is that not as much of a bias problem as the blow off 7NT?Of course, datum doesn't work at MPs... I'll deal with the 7NTxx-10 hands the one time a day I play against one to avoid all that nonsense. Please let's never go back to that distorting, wrong, easy-to-score-by-hand but we haven't done that since 1990 method of scoring. Quote Link to comment Share on other sites More sharing options...
barmar Posted January 13, 2017 Report Share Posted January 13, 2017 Butler scoring was a crutch in the days when bridge was scored by hand, since calculating all the cross-IMPs was extremely tedious for humans. It has no place when games are scored by computer. Really, you should just ignore the effect of the 7NTxx hands, since it affects all the pairs playing the board equally. All that matters is your relative score among your peers, not the absolute number. Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted January 13, 2017 Report Share Posted January 13, 2017 If 15 out of 16 tables make a routine game (including at your table), and one (other) table plays in 7NXX 4 down, then against that table in isolation you are looking at about a +/- 20 imp swing depending on vul etc. In terms of your average IMP score for the traveller you are looking at about +/- 1.3 IMPs. Then if you consider its significance over a month of about (say) 250 hands (typical for the OP) its impact on your average score is about 0.005 IMPs. Bottom line? Don't let it get to you. Butler scoring does not solve the problem. It eliminates the 1.3 IMP aberration but at a much greater cost on the vast majority of other hands where everyone plays to win. Furthermore, Butler scoring has absolutely no effect on mitigating the problem of the scores of the players at the table where the offense happens. 1 Quote Link to comment Share on other sites More sharing options...
johnu Posted January 14, 2017 Report Share Posted January 14, 2017 A simple remedy, at least for the scoring aspect, it for BBO to adopt Butler scoring. You don't need to use Butler scoring. You could also drop out a couple of extreme score comparisons in the cross imp scoring that is used and accomplish the same thing. 1 Quote Link to comment Share on other sites More sharing options...
mycroft Posted January 16, 2017 Report Share Posted January 16, 2017 True, we could cross-IMP against almost all the results. But that only kills off the problems with the datum (increase in my score may decrease my IMP result, datum is not a bridge score). It might even kill the "but at MPs" - I'd have to do the math, but I'm guessing it would still zero out. However, it doesn't resolve the (much more common) issues that the extreme scores are valid (issue of the last tournament was whether, due to use of UI, -1100 at the table should have been -1400 or -1700; into -430 at the other table! Now do I feel bad if I don't get to score against that result/feel good that I don't have to score against that result - at the other tables?) and that because those extreme scores *compare*, the result on a board is never zero, and if the bias goes all in one direction (it was usually about 4-5 IMPs one way back in the datum days, but occasionally it was 25, 30) is that fair to the players sitting the other direction? What if the ghost of Barry Crane is sitting E-W? ("Why did Barry Crane not score as well at IMPs than MPs?" "+5, +5, +5, -17") Or the FP pair? Or, as I said in my last, the player who just will not be preempted, and bids all 52 cards when taking sacrifices? Quote Link to comment Share on other sites More sharing options...
Rain Posted January 27, 2017 Report Share Posted January 27, 2017 If you were in a tourney there would be a TD who could take some action. Otherwise, report these idiots to abuse@. We can block play for a while if nothing else. But we cannot adjust board results or invalidate the results of MBC. Quote Link to comment Share on other sites More sharing options...
USViking Posted January 28, 2017 Report Share Posted January 28, 2017 (edited) Thankfully I rarely encounter people who try to spoil the fun for others by jumping to ridiculous 7-level contracts. It might be a less than a one in a thousand deal occurrence. A few days ago, though, I was in a tournament where not just one, but two pricks pulled the stunt at different tables on the same hand. [removed names] Does anyone have any thoughts on the case, as in collusion? I know administration always has a lot to do, but I wonder if it might be worthwhile to look into these miscreants' hand records. FWIW they amusingly both rate themselves as experts, while the unofficial BBO Skill site rates them as advanced, which means they are really intermediate.

I think it charitable to give you the benefit of the doubt concerning whether you were ignorant of this forum rule which is regularly repeated, or deliberately chose to flout it. Thanks for being so swell about it. FYI I have made >10,000 posts aggregate at several internet boards, all with different rules, none of which I could pass a test on after my usual one initial cursory scan. Some boards are tight about privacy, some are wide open. IMO cheaters (playing to lose is as much cheating as anything), such as the two I named, do not deserve the same privacy rights as non-cheaters, but I guess that is a topic for another thread. I admit, though, I ought to have considered the risk of retaliatory behavior arising from public denunciation. Now how about you admitting you should have pointed this out to me. BTW I perused the two cheaters' full January results and counted 13 episodes of flagrant cheating between them. I will follow up with a report via PM to BBO authority. That aside, you quote a non-BBO rating site while conveniently omitting to disclose that it has been non-operational for three years, which I suspect was also known to you, The fact is, you weasel, I did not realize the site was not continuously updated in accordance with its FAQ. and in the very same post you express doubts about its accuracy, even had it been a live site, while equally conveniently choosing to assume that its inaccuracy tends to support your personal assessment of these players. Try not to be so dense. My obvious, only purpose in bringing up the skill ratings was to ridicule the two cheaters. I think I have a better grasp of the ridiculous. If you had any grasp of the ridiculous you would be saving your ammunition for the cheaters, rather than for the people who are trying to help you put the cheaters out of business.

I think it would be appropriate to retract this, since although the denunciations were public, the cheaters' real names remain private.

helene_t Posted January 30, 2017 Report Share Posted January 30, 2017 The table host can always redeal the board once a rogue 7NT bid has been made. Otherwise, I think you should just not take the XIMP (or matchpoints, for that matter) score too seriously. If you want a meaningful comparison, play team matches, or select one of the vugraph matches for comparison instead of the BBO field.

661_Pete Posted February 12, 2017 Author Report Share Posted February 12, 2017 Haven't been back to this thread for quite a while now. Some useful contributions (and some less useful, perhaps :blink: :D ). As it happens I saw yet another instance, only today. I was just kibitzing, and I noticed that the IMPs on a certain hand were more extreme than one might expect, so I looked at the traveller .... and sure enough, someone at a different table had raised partner's 1♣ to 7♣ with no HC points. This is self-evidently a "**** you, I'm outta here" message to partner, and was done for no other reason. No way can this stuff be prevented, I agree, and there are times when players need to let off steam.... BUT... I still think players who do this should get some sort of warning. I'll report this one seeing as I spotted it, but many go unreported. I wonder if BBO could be tweaked so as to automatically detect this sort of thing? Something like the following:If, in the MBC, RBC, Acol Club etc., any player raises from the 1 or 2 level to 7, and then goes 4 or more down, then BBO automatically flags the hand for attention of the Admins.This isn't going to happen in legitimate play all that often, so I don't think it would over-burden the Admins. All down to software, I'm afraid! Quote Link to comment Share on other sites More sharing options...

silvr bull Posted February 15, 2017 Report Share Posted February 15, 2017 I just checked, and we would have gotten about 300 reports today. And even if we had the resources to investigate this much, what can we do about it? We can cancel their accounts, but all they have to do is create new ones.This reply "what can we do about it?" shows a big part of the problem with BBO. I routinely report problems to Abuse, with copies of screenshots or hands to substantiate the report, but the only response is a form letter style Thanks for your report. There is never any indication that BBO will do something about the problem people, and I no longer have any expectation that BBO will actually do anything. I say BBO should institute a clear policy of zero tolerance for flagrant abuse, and immediately ban those individuals. Sure, they can create new IDs, but they would need to start with zero logons and zero time on BBO. Tables can prevent new players from joining, and BBO limits the activities that new players can participate in. After being banned a few times and having to start over, the trouble makers may decide that it is less trouble for them to just play bridge than to cause childish vandalism. When BBO does ban a problem person, BBO should also keep a record of that person's IP address. If the same IP address gets banned a second time, BBO should prevent logins from that IP address. The short answer to "what can we do about it?" is SOMETHING! Doing nothing about proven abuse only encourages the problem children, and makes good players want to leave.

If you, how much are you willing to pay? If me, can I have an opt out if I don't perceive it as a problem on the same scale as you? If someone else, they can already insulate themselves from this and many other antisocial phenomena by coughing up $0.25 to play in a paid tournament that has a TD. So presumably $0.25 is already too high a price to pay. Except that most of the good players are doing that anyway is my guess. Quote Link to comment Share on other sites More sharing options...
