DR. ELO'S LETTER TO GM EVANS
[Searching the Net I found this interesting letter from Arpad Elo in the Chesscafe archives.] June 19, 1987 To: Larry Evans Reno, Nevada Dear Larry: Thank you very much for your letter of May 29 and the inclosed literature on CHESSGATE. The latter is a sad commentary on the state of US chess and the USCF. I am very much afraid that the coming elections will not change the situation much. Most of the voting delegates are the clubhouse political types who will elect their own kind to the Policy Board. And those on the PB will be ever jealous of their small powers and suspicious of the masters. I hope I am wrong about the election, so let's wait and see. the Kalme claims, I was not convinced by his arguments and I don't think he convinced anybody. At that time (1975) I made an extensive probabilistic analysis of the situation which compared various likely events under the two systems of the match and without doubt the Fischer conditions favored the champion --- and in retrospect rightly so. This analysis runs to eight pages and if you are interested I could send you a copy. A shorter version appeared in the magazine CHESS but unfortunately I have no copy either of the article or of the magazine. Further in retrospect/there is a simple argument in favor of the Fischer conditions without any elaborate probabilistic calculations. I owe credit to one of our local players (Al Losoff) for putting me on the train of thought which I regrettably missed twelve years ago. It goes as follows: 1. If the match at any time stands at 9:9 it indicates an equality between the contestants. 2. Thus the next decisive game could go either way since the contestants have equal probabilities of gaining the next decisive game. 3. Thus a win by either player in the next decisive game shows no superiority any more than a single throw of a coin shows a superiority of heads or tails. 4. A 9:9 result then is properly declared a drawn match since the challenger has shown no clear superiority. I find this intuitive approach more convincing than any fancy probabilistic calculation and I only wish I had had the insight to see it 12 years ago. Who knows, we might have seen a Fischer-Karpov match. Or would Bobby have found other excuses for not playing? Cordially, /s/ Arpad E. Elo PS: Dr Euwe was Correct in his remark. AEE |

"Fischer refused to negotiate or compromise and his stubbornness is what killed the match - nothing or nobody else." - GM Evans (1975) _ "Karpov deserves to be world champion" - GM Evans (1975) _ "... Evans ... still holds that Fischer's stubbornness and nothing else killed the match. ... If Fischer had not been so stubborn, there would have been a match. ..." - Larry Parr (28 May 2002 08:11:07 GMT) _ "... Fischer must be slanged -- as both GM Evans and I have so slanged in thousands of words -- for producing asinine conditions. ..." - Larry Parr (05 Jun 2002 07:12:26 GMT) |

If the challenger won the next game, it would be 10 to 9, and he would have shown a clear superiority. If it is a match until one player wins 10 games, then the challenger needs to have the opportunity to win that 10th game, if it is 9 to 9. I would have expected better logic by Elo, but he was pretty old at that time. My impression was that either Dr. Elo was making some kind of odd joke, or else his logic cells were just burnt out. In particular, step number 3 falls flat on its face when it mistakenly tries to equate a toss of a coin (random chance) to GM Fischer winning that 10th game. (Insert Blairian quote here, of GM Fischer stating that chess is a game of *skill*.) -- help bot AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA |

To this Jud McCranie responds with: This doesn't make any sense to me. Whomever wins the next game as won 10 to 9. 4. A 9:9 result then is properly declared a drawn match since the challenger has shown no clear superiority. If the challenger won the next game, it would be 10 to 9, and he would have shown a clear superiority. Where is your treshold? Let's consider, for the sake of argument, a fast chess match, 20m+20s, 4 games per day, 5 days a week (20 games per week). They play till one of them wins 32 games. Would you still object to declaring a drawn match in the case of the 31:31 score? *** We need to accept the reality. We need to accept the fact that occasionally the competitors are so well matched that it is the question of good luck which of them wins. In such situations we need to decide about the our customs, and not about what is right and what is wrong in the chess sense. As long as the solution is fair, things are fine, and we need to be philosophical about the necessarily imperfect comparisons--there is no such thing as a perfect one. The classical (old?) chess tradition requires that challenger should show a clear dominance over the old champion in order to replace him/her. If we want to uphold this tradition then indeed a provision like 9:9 is reasonable. But is a match till 10 wins reasonable? That's a separate question.

Then the players are equal, and each has an equal chance to win the next game?? This argument is funny, it's a good joke, but it's not a good argument. If it gets to 1-1, should the champion retain his title? Then Topalov should get five points for free, and the right to soil Kramnik's bathroom. Seriously, when players are equally matched then there is no way to select one as the clearly better player. Every solution will favorite a non-chessical consideration or it's just like a toss of a coin; say the match went like this: 1:0, 1:3, 3:4, 4:5, 7:5, 7:8, 8:9, ... Can you really claim that one of the players is clearly better. The result depends on the lucky/unlucky cut-off interruption of the match. On the other hand, if it went like: 0:1, 0:2, ..., 0:8, 1:8, 2:8, ..., 8:8 then, under the (very) regular circumstances, it means that the first player, who was losing for a long time to the second player, has learned how to handle his/her opponent, and now that player prevails over the opponent. That's why long matches start to be something else, they would not be about the present strongest player, but about the present and future best player (if a match were a year long or longer).

The classical (old?) chess tradition requires that challenger should show a clear dominance over the old champion in order to replace him/her. If we want to uphold this tradition then indeed a provision like 9:9 is reasonable. No it isn't. If it is a match until the first player wins x number of games (draws not counting) then that should be it. Otherwise, play a limited number of games, draws counting, and if it is tied at the end of those games, the champion retains the championship. But is a match till 10 wins reasonable? I think that is too many. --- Replace you know what by j to email AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA |
