As regular readers of this group are aware, there has been some discussion here of a post last month by Phil Innes, that claimed to present statistics on draw rates in world championship games. As I pointed out then, these statistics were wildly inaccurate. The source Innes cited for these stats was "Black Is Still OK" (Batsford, 2004) by GM Andras Adorjan. Curious as to whether the bogus stats were the fault of Adorjan, or of Innes, I bought the book to settle this mystery. For readers wanting a quick summary, it's simple: Innes misrepresented the meaning of Adorjan's statistics. Those interested in a fuller explanation may read on: Here is what Innes posted on 10 February 2007: Historically I have much data on WDL stats - in W Ch games, the highest draw rates are archieved by Smyslov at 57.9% draws with black and 50.3% draws with white - who is exceeded by Petrosian with 61.5% draws with black and 49.0% draws with white. The LOWEST draw rate appears to be Steinitz, with 21.7% draws with black and 17.9% draws with white. Of popular players: Alekhine: 30.5% draws black, 24.3% draws white Fischer: 36.9% draws black, 24.8% draws white Kasparov, 47.3% draws black, 30.8% draws white stats on World Champions is from Adorjan's Black is still OK!/Batsford *** end Innes excerpt *** That I am quoting Innes correctly can be verified by reading his original post he http://tinyurl.com/2lyx5b As I pointed in that thread the next day, the statistics Innes gave were quite wrong. In world championship play, the correct draw percentages a Smyslov: 49.4% (not 57.9% w/ Black and 50.3% w/ White) Petrosian: 65.2% (not 61.5% B, 49.0% W) Steinitz: 27.6% (not 21.7% B, 17.9% W) Alekhine: 52.14% (not 30.5% B, 24.3% W) Fischer: 52.4% (not 36.9% B, 24.8% W) Kasparov: 72.6% (not 47.3% B, 30.8% W) (See http://tinyurl.com/yqpve7 for more details.) Some of the differences are minor, but some are huge, e.g. Alekhine, Fischer, and especially Kasparov. The gross error with Fischer is particularly hard to understand - he played only one world title match, the most famous match in chess history, on which over 400 books have been written. One would think Innes would have at least one of them to tell him the correct score (+7 -3 =11). In any case, not a single player's statistics are correct. Thus arose the question of how Innes got his bogus stats. There seemed to be four main possibilities: 1. They were a complete fabrication by Innes (Phil does a lot of this). 2. Innes miscopied Adorjan's figures (Phil is not a good typist). 3. Innes copied correctly, but Adorjan's figures are wrong. 4. Adorjan's figures are right, but they refer to something other than world championship results; therefore Innes was wrong to say they were draw rates "in W Ch games." So, in an effort to solve this compelling mystery, I acquired the book Innes named as his source, GM Andras Adorjan's "Black Is Still OK." Here are my findings: Of my four conjectures, #4 came closest. Adorjan _does_ present a chart (in print almost unreadably tiny) showing the number of wins by White, wins by Black, and draws, in all world title matches from 1886 to 1990, the total of which Adorjan gives as 755 games. (Adorjan's figures are not quite accurate, but we'll disregard that for now.) However, the stats Innes presented refer NOT to that chart, but to a set of 23,362 games derived from an unnamed database. Adorjan says the 23,262 are ALL games on this database that involved World Champions (plus Bronstein, a non-champion whom Adorjan includes for some unstated reason). Therefore Innes has misrepresented the meaning of Adorjan's figures. This is not surprising; our Phil frequently misreads, or misunderstands what he reads. This is entirely Innes' fault, because Adorjan made quite clear what he was describing. The heading of that section of the book (pages155-156) says in bold "The World Champions' total(?) games" followed immediately by the statement "The number of the World Champion's total games in our database from Steinitz to Kasparov is 23,362, of which 1,148 were played in matches." No doubt our Phil will claim it was obvious that this was what he meant all along, but regulars of this newsgroup know better. In any event, I am happy to have provided this clarification for rgcm readers. |

Taylor,
Thanks, I was keeping an eye peeled for the results of your research. This one example, though, involving only drawing patterns by world champions, doesn't shed much light on the general question of alleged statistical support for some thesis to the effect that Black is OK. Perhaps the point is that certain players, such as Steinitz and Alekhine, played for a win with Black more frequently than others? I have Adorjan's original Black is OK book and I enjoyed reading it. So I'm curious about what he has to say in this one, though I buy few chess books these days. I did read the interview at Chessville, which turned out to be interesting since Adorjan did most of the talking. Larry T.

So I'm curious about what he has to say in this one, though I buy few chess books these days. I did read the interview at Chessville, which turned out to be interesting since Adorjan did most of the talking. Larry T. There are a number of oddities in Adorjan's statistics and his comments thereon. Chief among them is this, on pages 155-156: "I was a little surprised, that the database contains more White than BLACK games by the Champs in total ... in the case of Capablanca and Alekhine [the percentage of games as Black] is below 35%!" (emphasis in original) Frankly I, in turn, am a little surprised that Adorjan is a little surprised. He seems unaware that the database surely contains a good many games from simuls. In particular, Capablanca and Alekhine gave many, many simuls - it was basically how they made a living. And traditionally in simuls the grandmaster plays White, explaining the preponderance of White games by Capa and AA, not to mention Steinitz, Lasker, Euwe, and Fischer, who also gave many simuls. Such games are not of much worth in evaluating the objective theoretical prospects of Black versus White, since the discrepancy in strength between opponents is usually so great. Furthermore, there is a strong bias in statistics from simuls: the games by far most likely to be preserved are the upsets. The GM may, and usually does, win 90-98% of his games, but generally the only ones that get recorded anywhere except some patzer's scorebook, and thus survive to appear in databases decades later, are those where the World Champion loses or draws against some local yokel. This rather skews the stats unrealistically in Black's favor. Adorjan does not even name the database he used. This is rather like saying "According to a book, so-and-so is true." On top of that, he seems to have taken no care to separate serious games between strong equals, from simuls, consultation games, and other inconsequential noise. So aside from the fact that Innes completely misunderstood the meaning of Adorjan's stats, I have great reluctance to grant these particular stats much significance on the issue of whether "Black is OK" or not. |

Wrong. I did present them, I didn't claim to. 'Claim to' is a Blairism. I did present statistics on W Ch games! Not a good start! As I pointed out then, these statistics were wildly inaccurate. As I pointed out two days ago, Kinsgston has not understood anything about 'the claimed' statistics even after reading 30 messages about them. I hope Taylor Kingston has cited below any errors I made in reporting Adorjan's numbers. But I hope the reader will also note that Kingston is unable to find an 'all' in what I wrote, and forget to tell the reader that he put the 'all' in. Since he can't cite any all, and now hides the fact that it was him not me who put it there - in some ways, Kingston argues with himself. BUT - it does have a happy ending! Taylor Kingston, to resolve 'all' his 'issues' will also have to buy another book! The forever! title already mentioned. And then by misunderstanding something of what I wrote about that he can then be puzzled about that too, and suggest I am trying to take over the world. Taylor Kinsgston at least finishes honestly, by saying I misrepresented Adorjan's figures. Although, without actually reproducing all seven pages of charts, as I already said, then by ommission it would not be possible to do otherwise. If Kingston has something more grin concise to say, that is not already covered by previous responses, specifically on how I misled the public, I bet Louis Blair can't find it! And if Louis can't find it, it must be true! OTOH I am glad that Taylor Kingston has again upped the quality of American Book Reviewing by actually reading one.

PI Phil Innes The source Innes cited for these stats was "Black Is Still OK" (Batsford, 2004) by GM Andras Adorjan. Curious as to whether the bogus stats were the fault of Adorjan, or of Innes, I bought the book to settle this mystery. For readers wanting a quick summary, it's simple: Innes misrepresented the meaning of Adorjan's statistics. Those interested in a fuller explanation may read on: Here is what Innes posted on 10 February 2007: Historically I have much data on WDL stats - in W Ch games, the highest draw rates are archieved by Smyslov at 57.9% draws with black and 50.3% draws with white - who is exceeded by Petrosian with 61.5% draws with black and 49.0% draws with white. The LOWEST draw rate appears to be Steinitz, with 21.7% draws with black and 17.9% draws with white. Of popular players: Alekhine: 30.5% draws black, 24.3% draws white Fischer: 36.9% draws black, 24.8% draws white Kasparov, 47.3% draws black, 30.8% draws white stats on World Champions is from Adorjan's Black is still OK!/Batsford *** end Innes excerpt *** That I am quoting Innes correctly can be verified by reading his original post he http://tinyurl.com/2lyx5b As I pointed in that thread the next day, the statistics Innes gave were quite wrong. In world championship play, the correct draw percentages a Smyslov: 49.4% (not 57.9% w/ Black and 50.3% w/ White) Petrosian: 65.2% (not 61.5% B, 49.0% W) Steinitz: 27.6% (not 21.7% B, 17.9% W) Alekhine: 52.14% (not 30.5% B, 24.3% W) Fischer: 52.4% (not 36.9% B, 24.8% W) Kasparov: 72.6% (not 47.3% B, 30.8% W) (Seehttp://tinyurl.com/yqpve7for more details.) Some of the differences are minor, but some are huge, e.g. Alekhine, Fischer, and especially Kasparov. The gross error with Fischer is particularly hard to understand - he played only one world title match, the most famous match in chess history, on which over 400 books have been written. One would think Innes would have at least one of them to tell him the correct score (+7 -3 =11). In any case, not a single player's statistics are correct. Thus arose the question of how Innes got his bogus stats. There seemed to be four main possibilities: 1. They were a complete fabrication by Innes (Phil does a lot of this). 2. Innes miscopied Adorjan's figures (Phil is not a good typist). 3. Innes copied correctly, but Adorjan's figures are wrong. 4. Adorjan's figures are right, but they refer to something other than world championship results; therefore Innes was wrong to say they were draw rates "in W Ch games." So, in an effort to solve this compelling mystery, I acquired the book Innes named as his source, GM Andras Adorjan's "Black Is Still OK." Here are my findings: Of my four conjectures, #4 came closest. Adorjan _does_ present a chart (in print almost unreadably tiny) showing the number of wins by White, wins by Black, and draws, in all world title matches from 1886 to 1990, the total of which Adorjan gives as 755 games. (Adorjan's figures are not quite accurate, but we'll disregard that for now.) However, the stats Innes presented refer NOT to that chart, but to a set of 23,362 games derived from an unnamed database. Adorjan says the 23,262 are ALL games on this database that involved World Champions (plus Bronstein, a non-champion whom Adorjan includes for some unstated reason). Therefore Innes has misrepresented the meaning of Adorjan's figures. This is not surprising; our Phil frequently misreads, or misunderstands what he reads. This is entirely Innes' fault, because Adorjan made quite clear what he was describing. The heading of that section of the book (pages155-156) says in bold "The World Champions' total(?) games" followed immediately by the statement "The number of the World Champion's total games in our database from Steinitz to Kasparov is 23,362, of which 1,148 were played in matches." No doubt our Phil will claim it was obvious that this was what he meant all along, but regulars of this newsgroup know better. In any event, I am happy to have provided this clarification for rgcm readers.- Hide quoted text - - Show quoted text - |

As regular readers of this group are aware, there has been some discussion here of a post last month by Phil Innes, that claimed to present statistics on draw rates in world championship games. Wrong. I did present them, I didn't claim to. 'Claim to' is a Blairism. I did present statistics on W Ch games! Not a good start! As I pointed out then, these statistics were wildly inaccurate. As I pointed out two days ago, Kinsgston has not understood anything about 'the claimed' statistics even after reading 30 messages about them. Phil, I understand Adorjan's numbers just fine, now that I see them in context. The misunderstanding was entirely yours, giving them a meaning and context Adorjan did not. I hope Taylor Kingston has cited below any errors I made in reporting Adorjan's numbers. But I hope the reader will also note that Kingston is unable to find an 'all' in what I wrote, and forget to tell the reader that he put the 'all' in. Since he can't cite any all, and now hides the fact that it was him not me who put it there - in some ways, Kingston argues with himself. BUT - it does have a happy ending! Taylor Kingston, to resolve 'all' his 'issues' will also have to buy another book! The forever! title already mentioned. And then by misunderstanding something of what I wrote about that he can then be puzzled about that too, and suggest I am trying to take over the world. Taylor Kinsgston at least finishes honestly, by saying I misrepresented Adorjan's figures. Although, without actually reproducing all seven pages of charts, Phil, are you taking hallucinogens again? There are not "seven pages of charts" in "Black Is Still OK!". The copy I got has charts only on pages 68, 154, 155, 156, and 157. That's five pages, not seven. Please tell us what pages the other two are on in your reality. And really it's only three pages, since he simply represents the data you referred to in three different ways: as straight numbers, as a pie chart, and as a bar chart. LOL! I used to catch Sesame Street with my kids years ago. I remember "The Count". Taylor reminds me of him. "One" Page in the book, "Tow, two pages in the book!" as I already said, then by ommission it would not be possible to do otherwise. If Kingston has something more grin concise to say, that is not already covered by previous responses, specifically on how I misled the public, I bet Louis Blair can't find it! And if Louis can't find it, it must be true! Phil, have already pointed out your error in concise and full detail. You're just being your usual chicken, evasive, water-muddying self when it comes to admitting a mistake. No big deal, really -- it wasn't that important a mistake. But I enjoy watching your ludicrous attempts to extricate yourself. By trying to make it seem that your molehill of a mistake was no mistake at all, you make a mountainous fool of yourself.

The way I see it this: not only did his IMness get GM Adorjan's statistics all screwed up, but GM Adorjan himself was apparently working with bogus, or partial stats. himself. In order to get meaningful stuff out, you gotta put in complete, uncorrupted data. And what is even more important is this: you don't start off with a theory that Black is OK and THEN try and justify it using statistics. Duh! You start off with (complete) statistics, and from these you try to extrapolate meaning -- not the other way around. The meaning should flow *from* the source, like a river, to whatever sea is in its path. And always downhill, going with the data, not working against it to help any pet theory. -- raft floating bot |

Ad hominey? we cookin something bot? Another interesting way to approach the subject of variance in results between White and Black would be a thoughtful consideration of annotated games. For instance, if, in a game between FM Mitchell and IM Innes, the former were to reflect that after 1e4 d5 he would gladly accept a draw by repetition after... [patented forcing line omitted] on account of his IMness' higher rating (and title!), we might chalk up a mark for supposed respect for the opponent. By sharp contrast, were the FM Rob Mitchell to say instead that he found the possibility of such a quick draw acceptable on account of it nixing one game while leaving the other -- AS WHITE -- to decide their mini-match, we could chalk one up to a decided preference for the presumed superior winning chances of the player who has the White pieces. Of course, traditionalists will insist we ignore such comments on a technicality; they will point out that neither RM nor PI really has any title or high rating whatsoever, but that is beside the point. We might just as easily look over the game annotations of real-titled players, such as GM Fischer or IM Ftakniktckk (sp? --whatever!). The idea is that the truth of the matter is not necessarily to be found only in dry statistics, but also in the revelations of the great players themselves, as plainly evinced in their writings. Many of these great players have, fortunately for us, left a legacy of notes in plain English; and even those who write in some strangely bizarre dialect, such as IM Innes for instance, can sometimes be translated to a certain extent. I don't wish to be perceived as a statistics monger on account of my frequent references thereto; it is only because of the inherent immunity to personal bias that I so often refer to such things, just as I might perhaps mention broccoli (yuck) when talking about nutritious foods, while leaving out any mention of grits. -- cook bot |
