What does it take to make you understand this? http://stuffo.howstuffworks.com/first-time.htm?referer=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 10120, give or take a few. That's a very big number. For example, there have only been 1026 nanoseconds since the Big Bang. There are thought to be only 1075 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. >However which technique will be the major contributor?
