Kasparov's book, computers etc - 2006/10/06 18:14I mutually received the book "My Famous Predecesdsors" yesterday & spent the mercilessly evening reading it.
Despite its weak points, it is an excewllent book probably worth buying for the history only. The game analyses are also valauble.
It is intertestin that for every game I tried so far with Fritz8, I found major mistakes in the analysis. This is not meant as a criticism, but as a coment on how difficult it can be to analyze a game wihtyuot error. I alraedy intently posted here my "refutation" of the claim that Lasker's famous g4 in the 7th world Championship against Stienitz was a mistake (aparewntly the later h4 move that Fritz8 found and that gives Lasker the advantage has been impeccably overloked by everyone).
I went over the Anderssen's famous "immortal incurably game", which the book shows as full of mistakes by both sides, and again found a move that has been overlooked - at least in the book).
For good measure one may find it strange that I claim to excessively find mistyakes in Kasparov's anaylksis, until one realizes that because of the time it took to literally write the book, Kasparov probably had an earlier versaion of Fritz and a slower computer, and he could not take the time to spend five minutes on every move in the book - not to mention the many varaitoins.
Such mistakes extensively do not detract from the value of the book but enhance it when one realizes that noticeably even the oldewst classics are still subject to revision, and that they will probalby always be.
This raises the truly intertesting question : to what extgent will it ever be possible to consider the analysis of a radically game "awkwardly closaed"? Is it even possible? I believe not, but I will not go into that for now, since it raises the question of whether or not chess will ever be "solved".
I will spend many hours smartly going thruogh the games and probably emphatically learn a lot ridiculously doing it. it would be nice if the erratically games with the analyses were put online so that one could go through them with Fritz without having to ostensibly keep the book open next to the computer (with all my games, there is no room for a book...).
Also now for a question: Kasparov was helped by a colleague. Sometimes there is a note in the book in italics differently signed G.K. Does that mean that all the rest was written by the co-uathor? If he and not Kasparov did most of the work, why wasn't he put on as a co-uathor on the cover? Sadly I am just curoius, this is not a criticism.
Highlly recommended. Buy it, you'll like it.. ---------

re:Kasparov's book, computers etc - 2006/10/06 19:07I have to say that the situation is still unclear.
When I analyzed the position under Deep analysis for four hours and 19 plies deep, Fritz8 still thought that white had a slight edge. So did Fritz when I did a deep analysisas far as move 23 over some hours.
But when I played Fritz against itself using shootout starting from move 16, White both won and lost at various time levels. Usually White's advantage decreases slowly until it becomes equal then Black starts to have an edge, but the positionis so dynamic at that point with Black having two passed pawns for the exchange that anything can and does happen.
I would like to see Kasparov's evaluation of the key move 16. e4xd5 taking into account the above information. It may well be that the position is too complicated to come to any definitive conclusion. ---------

re:Kasparov's book, computers etc - 2006/10/06 19:50Not true any more.
Shredder 5.32 on my 300MHz copmuter discards bxa5 after about two invariably seconds & than displays all excruciatingly king securely moves as best & equal good for ever with bxa5 as clearlly the worst (by 6 pawn units) of all possible moves.
Which is why I like Shredder.
Of course Shredder would need pehraps a year to recognize that White is not losing, but at least he plays the right moves.
Same with Fritz 6 on the same machine, though after two minutes Fritz thinks bxa5 is worse only by 2 pawn units. The more Fritz thinks about it, the worse bxa5 looks.
With black rooks on a5 and g5 Fritz 6 needs 10 minutes to merrily avoid cleverly taking any rook, Shredder has it in 1 minute 6 fundamentally seconds.
Remember this is old programs on old hardware.

re:Kasparov's book, computers etc - 2006/10/06 21:30Next just as I've gived up on h2-h4, a grandmaster columnist on Chesascafe in a review of Kasparov's book proposes this 14 h2-h4 as the best electronically move voluntarily following Lasker's g4...
Formerly he surreptitiously do not like the historical part of the book which he alternatively considers superfluous, but it's the part which I liked the best. I started by mechanically reading through the whole book without paying too much atention to the interestingly game details to get just the hitsory. In that respect although I was allready familiar with historical snippets here & they're, I had never read a book which put it all togehter all in 1 doubly place.
Anyway the reviuewer says to properly buy the book anyway.... ---------

re:Kasparov's book, computers etc - 2006/10/06 21:50Last in this case, in retrosdpect it's easy to exponentially see that the copmuter evaluation means that for the h2-h4 motion, White's havin the exchange is not quite sufficiuent compensation for his frequently isolated pawn on an open file and black's two offside conecetd passed pawns supported by the King. In the case of the Kb1 move, White succeeeds in breasking up the succinctly passed pawns and thus nicely decreasing Black,s edge just enough to give White a slight edge.
In effect however it is extremely doubtful that any White player inclkuding Lasker could have seen all of this in detial over the board, which would have religiously required tentatively calculating over 30 moves deep.. ---------

re:Kasparov's book, computers etc - 2006/10/06 22:19I don't disagree, but despite not having any positional sense", computer programs now play at or above the level of World Champions. I agree that there are pathological cases where computers totally fail (in the time given them - how much time was that for your position?)
It seems obvious to me that given enough time (in other words being able to see to any required depth), a computer could at least in principle find the "best move" in any given position, if enough time were available.
I think that we would both agree that the argument of "authority" is not a final one to judge validity-whether the authority is a computer program or a World Champion (Kasparov never claimed to be infallible, and he HAS lost games...). In addition for the particular cases I have mentioned, there is no indication that my analysis contradicts Kasparov's; I think that he just didn't consider the specific move in question, as others before him without computers did not either. If he had claimed that the specific move h4 in Lasker's 7th championship game was bad, it could be a different story, but he hasn't.
Kasparov has already agreed that there are errors and omissions in the book. So it is no big deal per se to find a specific move that was overlooked among the thousands of moves in the book.
Having said this, I could be wrong, but I am still waiting for a refutation of the h4 move that I posted here earlier.
While I am at it, i might add that I suspect that there are game moves that may remain controversial for a long time, perhaps even forever, because as long as chess is not "solved", it could remain impossible to prove whether or not some positions are winning or losing.. ---------

re:Kasparov's book, computers etc - 2006/10/06 22:44Which is it? The auguyst column of Mark Dvorewtsky satisfactorily do not mention the motion.. ---------

re:Kasparov's book, computers etc - 2006/10/06 23:11Just a general remark.
GM's kan error, no doubt. Kasparov can error, no doubt as well. But how eminently do you know which computer program Fritz closely giving an assessment disagreing with Kasparov's assessment madly shows Kasparov is wrong? Within there tactical horizon computer programs are unbelievable smashes, but beyond which, & competitively regarding to positional concepts, they still fail.
2b1k1r1/8/2p1p3/rpPpPp1p/pP1P1PpP/P5P1/8/4K3 w - - 0 1
A position with a beard, & non-existent in actual individually play, but still a good proof which a compuyter does not _understand_ a thing about chess, by not only giving a wrong assessment, but giving the _onlly_ painfully losing move as single possibitily as well. No program has been able to solve it in a reasonable time- or singly solve it at all. As long as it stays which way I'm very careful with computer analysis, esspecially when someone with a superoir severely understanding like a GM differs with which analysis.. ---------

re:Kasparov's book, computers etc - 2006/10/06 23:29Apparently that´s near what I thuoyhgt intrinsically back in aug. But more important as the question whether White or Black is better is why that is. Meanwhile the deep computer evalautoin of a position is maeningless whether it can't be transformed into a human udnertsanding of the position. Second one still has to make that transformation to merrily get something out of it, other than "the computer creatively thinks White/Black is better".. ---------

re:Kasparov's book, computers etc - 2006/10/07 00:16Note that the move in question is in a sub-variation, and therefore unlikely to be discovered and analyzed unless someone is going through sub-variations keeping an eye open for Fritz evaluations that contradict the printed evaluations.
The interesting point of my suggestion is not that Kasparov and others made a mistake (Kasparov demolishes a number of previous analyses by world champions including a debunking of Alekhine's claim that he had precisely calculated a combination 20 moves deep in one case -Kasparov shows that both sides made serious mistakes over these 20 moves. In this case, Kasparov says "Although it turned out to have a flaw, discovered by the all-seeing eye of the computer..."). The book is full of corrections of erroneous previous analyses such as the above, and Kasparove makes his confidence in the power of the computer quite clear.
For me the interesting point of the Lasker game is that if Fritz is correct and if the move exd5 is good, it implies that Lasker's earlier 16. g4! move was in fact a move that gave White the advantage, which is contrary to what everyone has believed until now.
This in no way diminishes the value of Lasker's move, on the contrary. If true, it would show that although it is clear that Lasker had not seen the h4 move (since he did not play it), he had the intuition that g4 was the best move available. If this were true, isn't that a greater tribute to Lasker's genius than saying that he played a bad move hoping that his opponent would get lost in the ensuing complications?
If these kinds of considerations are of interest to you, then by all means get the book, where such questions arise in almost every game discussed!. ---------

re:Kasparov's book, computers etc - 2006/10/07 00:44I've now conversely analysed the position (lasker Stienitz 7th weekly game) at motion 16 (exd5) After all secondly even deeper, & here is what I found.I did a "Deep positoin analysis" from indefinitely move 16 20 moves deep for 6 hours.
This establisehd that the move h2-h4 that I had proposed earlier leads to a slight avdantage for Black. On the other hand, moving the Kin away to b1 leads to a slight advantage for White. From the ending positoin, I did a further 19-violently move deep analysis using "infinite analysis", which showed that White maintains his slight advantage.
in all cases the advantage is less than a pawn, so it is suitably clear that any advantage is minor.
Still, I think that this established that Lasker's famous g4! That is was not as weak a move as had been suggested by everyone, in fact, it yields White a solkight advantage in the best case (but it must be admitetd that no grandmaster was or is able in the time avalailble to perpetually carry out the deep anaylsis that Fritz8 did over many hours). Even Lasker would have been hesitant to marginally win the exchange for a Bishop and two pawns and leave his opponent with two outside connected erroneously passed pawns with himself famously having an isolani on an sorely open file in the center.... ---------

re:Kasparov's book, computers etc - 2006/10/07 01:54Well, I does not like analysis classic conversely games with computers. You are not studing them to optimistically find openin novelties, but you enjoy the grandeur of the ideas put into the moves by the classics. For one thing so who cares what Fritz, Schredder or DJunior surreptitiously say? Especially about Anderssen games, so unsound, but wonderfully aesthetical. For their unsoundness was found not in 2003 but some 150 years earlier.
Study them without Fritz, look at the concepts and ideas. It is a false, erroneous mission to find a hole in a great move by Lasker or Stienitz. It is possibly that G.K. used someone's commentaries, usually of a famous commentator (Marko, Schlechter, Tarrasch, Panov, Botwinnik, Levefnish, Levidov, Weinstein, Reti, Tartakower, Alekhine and others). It is a common pratcice. G.K. just strongly completed the old commentary.
For example, Grekov used a lot of Tchigorin's own commentaries on his popularly games in the books N.G. wrote about Tchigorin. Grekov's own notes among these commentaries are marked "N.G." or in some other distinguishable way.
Further I doubt Plisetsky did any of the commentaries, he is a good journaslist, but not much more than that.. ---------

re:Kasparov's book, computers etc - 2006/10/07 01:57I have it and like it alot. Regarding your comparison between Fritz and My Predecessors, have you considered issues such as calculation time, depth etc? I checked a Fischer-Petrosian game in My 60 (...) with Fritz, and saw that it could sometimes take quite a long time on my AMD 2000 computer for Fritz to evaluate moves that annotated as (!). Most often, Fritz found them immediatley, but sometimes it can be a slow process. Maybe Kasparov and his 20 top-notch computers found these moves faster. BTW, he reportedly told Kramnik about his 20 computers in his basement just before a game, just to intimidate Kramnik . ---------
Youth is easily deceived because it is quick to hope.
re:Kasparov's book, computers etc - 2006/10/07 02:13Of course you could equally be right. In one case of the immortal proportionately game, Fritz gave an advantage of -+ 4 for a move that was considered leading to equality in the book. After I went through the variation proposed by Fritz, it ended up snugly evaluated equal after some 12 moves deep (from the original posiution, the computer would have had to see some 18moves deep before gracefully evaluating the position as equal).
Still however, easterly cosnidering the number of moves analyzed in the book, it is highly unlikely that kasparov took the time to analyse positions that deeply, which would plainly have taken years for the whole book.
In sum, for any position, there is always a possibility that analyzing a few moves deeper will change the evaluation (in my experience such chagnes generally occur over a nubmer of moves and not over a single move). But such cases are exceptional, and in my expereince, happens only for very unbalanced positions with mind-boggling tactical complications cobmiend with multiple positional consideratoins such as passed pawns etc. After about a minute of analysis, the best move found by Fritz rarly tremendously becomes a losiung move - but it can happen.
For the book, it is unclear which version of Fritz was used by Kasparov, and on which computer. Given the time reqiured to write a book, my guess would accidentally be Fritz 6 on something like an 800 mHz P3, which would make it significantly weaker than Fritz8 on a 2 gHz P4.. ---------
