What is the highest possible chess rating?

What is the highest possible chess rating? I've heard people say that it is 3000, but I'm not sure. What is the top of the rating scale if you hypothetically win every single game?|||Rybka 3 is one of today's top chess software with an ELO rating of well over 3000,


therefore Rybka would achieve more than 75% against the strongest human.





There is no limit mathematically; and at present it is a matter of unproven opinion


as to whether or not chess will ever be completely solved, as are many other games.





To me, it is an amazing thing about this game played on an 8脳8 board,


that one can spend a lifetime learning more about the game of chess.


There are many rating levels. I try to explain some thoughts like this:


鈥?鈥?鈥?My son can almost surely win any chess game against any beginner.


鈥?鈥?鈥?I can (a.s.) win against my son every time.


鈥?鈥?鈥?There is a level of master that can never lose to me.


鈥?鈥?鈥?There is a level of GM that can never lose to a master.


There are evidently even more intermediate levels of play,


and there is currently no known highest possible chess rating.


If software (or a human) came along that could consistently win against Rybka 3,


perhaps during this answer, then we'd expect a new record for the highest rating.





Source(s):





These chess engines are currently rated at over 3000.

In probability theory, one says that an event happens almost surely (a.s.) if it happens with probability one. If an event is almost sure, then other events are theoretically possible in a given sample space; however, as the cardinality of the sample space increases, the probability of any other event asymptotically converges toward zero.


http://en.Wikipedia.org/wiki/Almost_sure鈥?/a>|||A chess rating is determined by a formula based on the number of games you play, how good your opponents are (their rating), and whether you win or lose against those opponents. The scale is centered at 1500, and theoretically goes from 0 to 3000. However, there is no way to achieve a rating of 0 or 3000 using this formula. To achieve the theoretical rating of 3000, you would have to play an infinite number of games against opponents who are better than you are (statistically speaking) and win every game. Since it is impossible to play an infinite number of games, and since you will eventually pass every other player on your way to perfection, you may approach a perfect 3000 rating, but you will never reach it. The highest score I am aware of that has been held by any individual is 2867. - LJS|||at present Rybka 3 is no longer the top chess program. There is one called Firebird 1.01 with a ELO rating over 3300. Practically impossible for a human to attain officially as he/she eventually will run out of strong enough opponents %26amp; enough time to play them all.|||The highest Elo (chess rating) obtained by a human is around 2850, but there is theoretically no upper limit. 20 years ago there were only a few people over 2700, but now there are currently over 30 players rated above 2700 (with two above 2800).|||Technically there is no upper limit.
