Only delusional people, disconnected from reality think it can. End of discussion! Anyone want to refute this? http://stuffo.howstuffworks.com/chess1.htm In this tree, there are 20 possible moves for white. There are 20 * 20 = 400 possible moves for black, depending on what white does. Then there are 400 * 20 = 8,000 for white. Then there are 8,000 * 20 = 160,000 for black, and so on. If you were to fully develop the entire tree for all possible chess moves, the total number of board positions is about 1,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000, or 10^120, give or take a few. That's a very big number. For example, there have only been 10^26 nanoseconds since the Big Bang. There are thought to be only 10^75 atoms in the entire universe. When you consider that the Milky Way galaxy contains billions of suns, and there are billions of galaxies, you can see that that's a whole lot of atoms. That number is dwarfed by the number of possible chess moves. Chess is a pretty intricate game! No computer is ever going to calculate the entire tree. What a chess computer tries to do is generate the board-position tree five or 10 or 20 moves into the future. Assuming that there are about 20 possible moves for any board position, a five-level tree contains 3,200,000 board positions. A 10-level tree contains about 10,000,000,000,000 (10 trillion) positions. Any "garbage" about the 50 move rule is smoke & mirrors, the number of possible legal moves in the 1st 10 Moves of a game exceeds the number of molecules in the observable Universe.
