How is it possible to beat a computer in chess?

My wife is hardly Karpov or Bobby Fischer, yet she manages to regularly defeat chess games she's downloaded online (not Deep Blue or the really sophisticated ones). Since a computer cannot err, it will never make a move out of short-sightedness or carelessness. So how is it possible for humans to win against them?|||Unsophisticated programs would be easy to beat, but many of the programs have different levels. They limit the number of moves that it looks ahead, keeping it more on a reasonable level.





Why can people beat computer programs that aren't written to limit themselves? Because the number of possible combinations is too large for the computer to calculate them all.|||When the game is programmed the computer opponent is given a certain number of moves to "plan out" with a certain amount of time. So, if the A.I. can only see 4 moves ahead, and is given 30 seconds, it will find the best possible move within 30 seconds. At 30 seconds it will move to the "best move found so far" as opposed to the best or smartest move. Remember that it is a human who programs the chess game, so the games logic is only as strong the programmers logic (although there are many, many, many generic chess algorithms available on the net). And that is basically why your wife can beat a computer in chess.|||Hi,

you can.

computer doesn't often lose because it knows your next movement.most of methods that has been used until now, has been processed in it. but it depends on the game's programmer that how many method the game knows. and it's not possible for a game to know every method because they are so many from different countries. also there were one that knew almost all. and Garry Kasparov did a match with that and I'm not sure if he won or equalized.



you can win with an unknown method, for example one from another country or so old or so new one.



you may laugh but it's more possible for an amateur or beginner player to win than a professional.

personally I won a new professional chess version that belonged to my mother's laptop. I tried an Iranian method for that.|||because the makers of the game create a lines of programming that make the game play at certain difficulty levels. if they wanted too, they probably could make the robot win every time, but since its a game, they are going to make the robot mess up every now and then so the player has a chance to see whats going on and win. hope this helped!|||Most games are programed to make a few bad moves, so that it is not impossible. It also depends on the power of your computer. Otherwise it would win.|||the average iq of someone beating the computor in chess is 140 to 145.|||Impossible %26lt;%26lt;cheating%26gt;%26gt;|||that's what is considered as CHEATING no matter what|||NO.
