What is the classical time control for a world championship game ?
Fischer vs Spasky for example , did they play 40 moves in 2 I/2 hours ? Then after the 40 moves they get 5 min a move ? Are the rules the same for the next world championship game ? why not play Rybka at world championship time controls ? Would Rybka kill humans because it could think of so many moves in that time limit. ? How about Rybka vs Deep Fritz at world championship time control , who would win that? |

What is the classical time control for a world championship game ? In the old days, there could be as many as three minutes per move. When you factor in the fact that it is typical for the first ten or so moves to be played rapidly by rote, that can make for high-quality chess. Fischer vs Spasky for example , did they play 40 moves in 2 I/2 hours ? Then after the 40 moves they get 5 min a move ? In some games, these two were "in book" for fifteen or more moves, so it doesn't much matter. Are the rules the same for the next world championship game ? I don't know. why not play Rybka at world championship time controls ? Would Rybka kill humans because it could think of so many moves in that time limit. ? I think the oldsters who have been playing these odds matches want "less work" and "more money". It reminds me of some of the claptrap which has been published in Chess Lies magazine-- trash, churned out such as to make a mockery of the attempt to "support" our professional players. How about Rybka vs Deep Fritz at world championship time control , who would win that? Every year, a world championship event is played, with varying results. My comments that Rybka is the strongest have more to do with the extensive testing which has been conducted than with these hit-or-miss affairs. For Rybka to really show off its abilities, you would need to give it gobs of time; these programs do not tire easily, although their chips may ultimately get a bit hot under the collar if pressed too hard, for too long... . ;D -- help bot |

Chess Lies magazine-- trash, churned out I was looking at the latest issue at breakfast and a tiny bit of grease from my bagel fell on the page. I tried to wipe it off, and the ink immediately ran and smeared becoming instantly illegible. Not only poor writing, poor articles, but poor production.... and yet we can't opt out in our membership, we have to pay for the thing whether we want it or not. It's barely changed since I first read it in the 1960s --- bad then, bad now. It even just about looks the same. |

It's barely changed since I first read it in the 1960s --- bad then, bad now. It even just about looks the same. I have noticed a few changes: 1) The old Cold War garbage is gone. At one time, the editorial slant was so severe, it is a wonder that the type itself did not slide off the pages. 2) Now, there is a lot of computer-assisted analysis. Trouble is, when the annotators decide the computer knows more than they do, there is a strong temptation to stop thinking and just let the machine do every- thing; time being limited, the result can be a shallow anno-Fritzation, easily refuted by a somewhat deeper analysis, or even a Fritz-look at positions the annotator may have just skipped over to save time. One example was an article on GM Boris Gulko, where the writers chose a theme of "watch his perfect technique", so to speak. Problem was that later in the game GM Gulko essentially threw away two-thirds of his accumulated advantage by a careless blunder; this was "handled" by pretending it never happened, which is why I am not impressed with the quality of these puff- pieces. It reminded me of another, very similar puff-piece from the old days in which GM Pal Benko, who wrote about the endgame, penned a piece about "why all Rook and pawn endings are drawn". His choice of game could not have been worse, for as he was expounding on how simple it was for an endgame genius like him to draw the position, I did a little research. It so happened that I found the exact same position in an endgame reference by two Russian GMs: Smyslov and Levenfish, and it was a "book win"! And a very instructive one at that. You know the worst part of this example? The fact that I "knew" to look it up, whereas GM Benko thought he knew everything, that he understood such endings perfectly. You see, after playing over "Alekhine's Best Games of Chess", I could just /feel/ that there was a possibility of more than a draw; that a /real/ chess player could not so easily be held to a draw. Now, it's Rybka; the blasted program basically /cheats/ in the endgame, often winning positions that nobody ought to have any right to win. It does so invisibly, imperceptibly, almost magically. I want to point a finger at the other programs' contempt factors, as there must be /some reason/ they play so stupidly! -- help bot |

there is a strong temptation to stop
thinking and just let the machine do every- thing; time being limited, the result can be a shallow anno-Fritzation You raise a point that others have raised and it is a good one. I have read also in a number of places that now the trend is toward concrete analysis rather than understanding the position, with computers having pushed us to this. But in addition to what you mention --- the trend to just let the computer do it all and then to blindly believe it, this trend accelerated and supported by the amazing things engines like Rybka can do --- we tend to forget that chess for fun (even very serious fun) is played by people, over the board, and the kind of concrete analysis featured in Chess Lice and many new books is all but impossible for even the world's top players. When real people play real chess, positional understanding and general principles still play a large role, as they must. A good case in point: this past weekend I was playing over a game from the marvelous book of the renowned Zurich 1953 tournament. A position was reached (I think in the third game in the book; I don't have it in front of me) in which the annotator (Bronstein) though Black had a bit of an advantage, and mentioned a move for White (one that I would have likely played) as being unappealing. I didn't see quite why so I set up the position with Rybka and poked around for 20 minutes or so. Interestingly, though Bronstein thought Black had an edge, Rybka gave White anything from a 10 to 25 centipawn edge depending on the continuation, this based on deep and complex analysis with some very unobvious moves in the projected lines of play (the move I liked and Bronstein did not like was indeed inferior for White, but only in that White would have less of an advantage). But in a practical sense what does this really mean? A 10 centipawn edge is dubious at best for a human player. 25 centipawns is better but still it's something that a computer understands and a human would have a much harder time converting into something tangible. And, go a few plies deeper and we swing another 10 cp in either direction. We are fooling ourselves if we think this is any sort of practical guide in real-life play. In fact, as the position stood, and as it would be played by humans, even top grandmasters, Black did have an edge simply in the fact that there were positional considerations that humans could understand and deal with. Those considerations would have been overturned by extremely deep and complex concrete analysis of which only a computer is capable. The computer would have perhaps won with White (certainly not have lost), but in the real game, Black pushed his "real life" advantage and made a win out of it. To take this exposition to an unexpected conclusion, this all explains why I like Sanny and I like GitClub. They make very human errors, the kind of errors and blunders that I make. I can relate to them. I cannot relate to Rybka on any level. |

Well, some of the computer vs. computer games I replayed had Rybka winning endgames which most humans would give up as impossible to make headway in. In these games, I could not pinpoint the specific errors which led to the opponents' downfall, and no information was provided as to how those programs evaluated the positions as they crumbled. But there are plenty of cases where strong programs will improve on "theory", and all that is needed is to see the improvement and its immediate follow-up in order for us to understand perfectly, so to speak. Often as not, it is just a clever tactic, or a material sacrifice which we reject out-of-hand but which the program takes the time to evaluate objectively. I read quite a few "raving reviews" regarding the GM Bronstein book you mentioned, and with great expectations I began to peruse a copy. I was greatly disappointed in that the opening moves were just glossed over, when in fact the positions were very complex and anything but obvious. I vaguely recall that the author might jump clear to move fifteen before offering any insight as to what was happening, and heck, by then I would have already lost a piece or something. Those guys were playing openings and lines I knew little or nothing about, so you could say that the book was "over my head" and dismiss my criticism; but then, you would have to do the same thing for many, many others-- just let them drown, the patzers; this book was intended for Russian GMs, not you! My favorite in that vein is where each of *several* different grandmasters independently annotate the same games, but it is never done fairly, equitably. In reality, one GM will go to print first, then later another will add his own commentary, correcting a few errors of the first guy along the way. Then comes GM number three, and so forth down the line. The first guy never has a chance to correct anyone but the two players themselves... . -- help bot |

I seriously doubt that; generally speaking, I find the text more interesting than the games themselves. The exception is where the text is nothing but blather. I have the 2nd russian edition of the book. It iincludes two intros, both to the first and to the second edition. Bronstein wrote in both introductions that his monography is devoted to the middle game. I hardly expect an author to expound on the virtues of 1. e4 e5, 2. Nf3 Nc6, but most of these games became "interesting" long before any commentary whatever appeared. At the time the games were played, most strong chess players would have been familiar with the then-current fashions in the openings, but this book has been raved about for decades afterward, and there is a gaping hole between the more recent fashions, and what was then well-known. Perusing the recommendations given on rgc, it becomes apparent that the older such a work is, the greater its chances of being praised in the same manner as this book has been. My conclusion is that people tend to recommend books which were recommended to them, years, if not decades earlier, for the quality of such books is simply not up to par; not up to the standards which would bring the books to the top of any purely objective list. Example: Basic Chess Endings, as we know, is filled to overflowing with analytical errors, yet it has been mentioned time and again as one of the "best" endgame books; when people complain that they were unable to read it, the answer is offered up: it's a reference work, not a romance novel. But that brings us right back to /quality/ again; a reference should have few if any careless errors, unlike GM Fine's effort. Now, if it was not possible to write without so many errors "creeping in", then we would have to choose among the possibilities using some other criteria; but in fact, there /are/ endgame books with no discernible errors, let alone enough for a compendium of them to render another book in its own right, as with BCE. Now that I have a very strong chess engine handy, I could probably look over the gaping holes in GM Bronstien's famous work, but I now have the impression that all these recommendations are worthless; just look at some of the books highly recommended here-- they are mediocre at best, while a lot of more modern works are systematically overlooked. It's nostalgia that rules the day, not quality. If you go to the Web site jeremysilman.com, you will find what is purportedly the biggest collection of chess book reviews extant; but looking over some of these, I discovered that books on the primary reviewers' favorite chess openings are covered in-depth, while books on say, cave paintings by hump-backed camels are glossed over, not really reviewed at all. There is a /huge/ variance in the length and depth of the reviews, and as the averages indicate, even the numerical scores given by the various reviewers vary widely in meaning. For one or two reviewers, a book given a 9 means it was fairly good, while for others, a 9 means it is the finest book ever written, on a pet line in the reviewer's very favorite chess opening. It's all subjective, and sometimes, very, very shallow. -- help bot |
