In other words, Sanny, you were lying. Guessing something does not mean lying. There are many things that we do not know for certain and we guess them. Say after an Exam someone asks you how was the exam, I say It was good I feel I will get 60% marks. But then I get 40% marks. It do not mean I was lying. In Chess who will win can never be said before. There is always scope of improvvement. Even deep blue on a supercomputer was beatable. Even Rybka & Fritz get beaten in some games. But they win most of the time. We can say Fritz & Rybka as an Example of Perfect Game. Just as I think Master Level & Advance Level play perfect games. But that do not mean they will win always.

In other words, Sanny, you were lying. Guessing something does not mean lying. Sanny, the plain fact is that you claimed your program was perfect. You had absolutely no basis for that -- not even the slightest grounds for even guessing that it might be. On the contrary, you have on file hundreds of games proving that it is very imperfect. Just as I think Master Level & Advance Level play perfect games. See? You're still doing it, after admitting you have no basis whatever for such a claim! As we say here in the USA, you are talking through your ass. |

So, what are your thoughts on "Solving Chess"? Instead of focusing on draws or perfect defense, a better approach would be to focus on the idea of endgame table-bases. The reason is simple: no matter how deeply you might *calculate* defenses to various and sundry attacks, you could never be certain that there is not a deeper strategy of attack which has not been anticipated, which can prevail. A simplified example of this is where, for many decades, grandmasters preached that certain positions could not be won-- only to die and have their great-great-grandchildren discover they were dead wrong. The strategy was beyond their grasp, but real nonetheless. With the endgame table-bases, no such errors creep in. Sure, there will always be people who maintain that there are more data than can be "held" in the molecules of the "known universe" or whatever, but we've already seen their kind get trampled under- foot before, under the heels of technology and its relentless advance. These small- minded folks remind me of the old days, of back when nearly all the pundits screamed that no chess program would *ever* defeat a master... later changed to "grandmaster", for the obvious reasons. I say that these endgame table-bases *can* be beefed up more and more, until they eventually reach a point where they meet super-engines somewhere in mid game. Right now, Best Buy sells hard drives which can hold more than the nay- sayers said could ever be held, and the price is within reach of ordinary folks. Ten years hence, I expect BB to have been bought out or taken over, but Wal-mart, Wal-mart will then likely be selling drives which wirelessly connect to our Apple computers (yes, APPL) and which can hold 7, 8, or maybe even 9-man TBs with no trouble at all. Given sufficient time, chess will be solved-- at least to the extent that man will know the definitive answers to such questions as "was Bobby Fischer's Bxh2 a losing move, or could he still have drawn?" And chess engines will be so strong that the question of \winning will be moot; the goal of the world's top GMs will be to somehow squeak out a draw. There will necessarily be a reversion to the old days, to the days of Knight or Rook odds. Discussions will center around just how far can a chess program go, in terms of contempt factors; 2 pawns? Three? Even more? -- help bot |

First off, the "Sanny/ttk5" exchange appears to be SPAMBOT based and
off-topic. Is there any way to delete those messages or at least ban Sanny from posting here? Thank you VERY much for introducing me to the concept of "zugzwang" as I had never previously considered the possibility that chess was an inherently flawed game from the very beginning. I feel like I did when someone introduced me to the concept of oligarchy relative to the concept of politics. ;o) Or perhaps the so-called flaw was actually a form of "trap" that you had to be sure to prepare for and avoid ahead of time? I guess that is the end result either way, a bummer dynamic for the naive or lesser- achieved person? I also get the feeling from the responses above as well as those sent to me privately that the concept of "perfect" is relative depending upon a person's personal opinion or frame of perspective. In other words, in my opinion, there are so many different possibilities for very good plays in the opening and middle games such that the only real "perfect" result would be the game ending in a draw period. A perfect game of defense for black would be to counter or block white's initial theoretical advantage and black's ability to lure white off of a previously-planned successful path. Now obviously I am talking about a perfect game by BOTH players. A perfect game for either side obviously results in a win and I agree that a good endgame database, very soon to be a "totalgame" database, is essential. Thanks! |

However, what if the SECRET to solving chess is in the "draw" dynamic? In other words what if the solution to chess was in playing perfect "defense"? Would not a perfectly played game of chess NOT result in a draw? How else could it end? The ONLY way that someone "wins" is if a "mistake" was made, right? Therefore, if someone wins then that was NOT a "perfect" game played by both sides. It has been said that it is possible for white to force a draw in a number of ways but I am talking about a "perfect game" here where both sides apply perfect strategy which is oriented or strategized toward long-term defense more than offense. I know that some people think that the game would then just be "stuck" with no one able to move but this dynamic plays into what I call "viable strategy" where a stuck game draw is the same as a loss for BOTH sides. In other words, a "true" draw under the "perfect" scenario ends with ONLY the two Kings on the board. So, what are your thoughts on "Solving Chess"? Any thoughts on the best chess game ever played by either human or computer would also be greatly appreciated. Thanks for your potential participation in this intellectual inquiry. I think we can never know the answer to the question of the solvability of chess: http://members.iinet.net.au/~ray/Chessgames.htm www.iinet.com.au/~ray |

, pialogue writes First off, the "Sanny/ttk5" exchange appears to be SPAMBOT based and off-topic. Is there any way to delete those messages or at least ban Sanny from posting here? It is a public newsgroup anyone can post here. I find the constant bitching about alleged USCF misdeeds far more annoying than Sanny YMMV Thank you VERY much for introducing me to the concept of "zugzwang" as I had never previously considered the possibility that chess was an inherently flawed game from the very beginning. Same with opening theory. Every now and then someone comes up with a new approach that for a while breaks the previous conventional wisdom. Finding novelty prepared traps in openings is now key to winning in the big engine vs engine matches. Offline taking days the engine can prepare deep lines for the opening book that target known weaknesses in its opponent (or more accurately believed to be known weaknesses). Typically this preparation has to be guided by human intervention (at least so far). I also get the feeling from the responses above as well as those sent to me privately that the concept of "perfect" is relative depending upon a person's personal opinion or frame of perspective. In other I don't think that at all. If the game is won for white then there is at least one perfect game where no matter what black does white can force a win. The trouble is that you may have to explore the entire full depth of the game tree to prove it. In real OTB chess games there is an element of bluff and counter bluff. Some good moves are weaker than perfect but invite an opponent to make a plausible looking mistake. But a perfect opponent would not be so distracted by such tricks. Humans are though. Putting a piece down hard sometimes gives added gravitas to an otherwise ordinary move. words, in my opinion, there are so many different possibilities for very good plays in the opening and middle games such that the only real "perfect" result would be the game ending in a draw period. A perfect game of defense for black would be to counter or block white's initial theoretical advantage and black's ability to lure white off of a previously-planned successful path. In real play yes, but in game theory the final outcome of a deterministic game like chess with perfect play is one of win, draw or lose for white. We just don't know which one it is. Now obviously I am talking about a perfect game by BOTH players. A perfect game for either side obviously results in a win and I agree that a good endgame database, very soon to be a "totalgame" database, is essential. Endgame databases attack the problem from the other end. They are complete and exact and show the number of moves to every final game state from any given position on the board using up to N=6 men. The number of states and the size of the database grows alarmingly fast with N. You can probe these online to see how it works at: http://www.k4it.de/index.php?topic=egtb&lang=en You can extend this back a to around 8 men with tools like Freezer (although its interface takes some getting used to). Freezer souped up a bit on a 64bit architecture might be OK for some 9 men problems. Beyond that the sheer size of the databases and the computational effort to make them means only special cases are ever likely to be studied in depth.

Just as I think Master Level & Advance Level play perfect games. * See? You're still doing it, after admitting you have no basis whatever for such a claim! A sentence should be read properly. I said "Just as I think Master Level & Advance Level play perfect games". Here I said "I think" Which means what I think about something. It does not mean I am going to bet for it just because I think of it. Here, I am proposing something to have more information so that I can judge whether I was Correct. "I think today it will rain" It just means I have a belief that it will happen. There are chances that I may be wrong. But Still I am thinking that way. Because the Probablity is more than 50%. I am proposing something to have more information so that I can judge whether I was Correct. I suppose that clears the objective. Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html |

Sanny, you already have oodles of information showing that your program plays nowhere near perfectly on any of its levels. It is poor- to-mediocre at best, atrocious at worst. You are quite clearly NOT correct. So, you are either a liar or a fool. Which is it? |

We just don't know which one it is. well after some comprehensive analysis with Ryba i now strongly suspect it's a draw.. so computer chess games probably will become boring in future, eg. Hydra vs Rybka, if Rybka would play on a strong multicpu, than the outcome should be a draw. so you could indeed say that normal chess is 'dead' as the late R.J. Fischer claimed, probably also to promote his random Fischer (or 360) chess; maybe in computer chess it also would be interesting to abolish the 50 move draw rule, as with the 6, and later 7 man endgame bases we could get interesting results (?); also in random/shuffle chess. best regards jef http://superchess.blogspot.com |
