Based on recent news (regarding Chinook), I’ve learned that checkers has over 500 billion online pharmacy without a prescription different combination of moves. Chess, however, has an astronomical amount, but can we say a rough estimate of how many?
Interesting. Thank you for that bit of information. I saw a few with "500 billion billion" and assumed it as a typo, since most said "500 billion". Your source is the first one stating 39 trillion. Thanks.
in chess there are unlimited number of moves, becuse you can move pieces backwords, but the minimum is 2
Better check your numbers. Chinook calculated 39 trillion possible combinations for only 10 checkers on the board. Jonathan Schaeffer, chairman of the department of computing science at the University of Alberta said that there is not enough computing power available to calculate all of the possible positions in checkers, but the New York Times used an estimate of 500 billion billion.
According to Mr. Schaeffer, the number of moves in checkers is roughly the square root of the number of moves in chess, so if you square the 500 billion billion estimated moves for checkers then you would have an estimate for chess.
500
Isn’t there an unlimited amount in both?…in chess almost every piece can move backwards, and what if a checker got kinged, then it can infinately move around the board
the number of move in chess never was calcultated, it’s WAY to big.
In the first 10 move in chess, there’s 17T possibility. ( 17,000,000,000,000 ).
So I think I’m pretty "safe" to assume the number of possible moves during a game would be AT LEAST 17T ^5, which would give something like : 141985700000000000000000000 000000000000000000000 0000000000000000000.
500 or something like that
