and if you were rated higher then the computer the you would be expected to beat it more often than not and so you will gain still fewer rating points for beating it. If you were rated slightly lower than the computer then you will gain fewer rating points. If you were rated very much lower than the computer before the start if the game then the computer would be expected to beat you most of the time, so you will gain a lot of rating points for beating it. The amount it goes up depends upon the rating difference between you and the computer before the game started. Since you won the game your rating will go up. Let us start by assuming that you and the computer both use the same total time during a game and that you win the game. The basic principles of the rating system are very simple. The computer adjusts your rating at the end of each game, according to the result of the game and the relative thinking times used by you and the computer. Your computer can estimate how strong you are as a chess player from the results you score against it and from the amount of time you take to think. PLAYER RATING SYSTEM: How Good is Your Chess?
