There is a game with even more possible moves and variations and it is called Go. "There are even more possible variations of chess games than there are atoms in the observable universe." (If you rule out illegal moves that number drops dramatically to 10 40 moves. It is estimated there are between 10 111 and 10 123 positions (including illegal moves) in Chess. This is the Shannon Number and represents all of the possible move variations in the game of chess. Which is a lot. But.amazingly, there are even more possible variations of chess games than there are atoms in the observable universe. That’s between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms. There are between 10 78 to 10 82atoms in the observable universe. So why did it take so long? Remember the question at the start? The following year the improved DeepBlue beat him 31/2-21/2. That did not happen until 1996 when DeepBlue beat Gary Kasparov. In 1950 he wrote a paper asserting this possibility, but it wasn’t until the 1970’s that computers began to defeat humans at the game – generally poor players who made silly mistakes. Using maths and logic to understand the world around him, it wasn't long before Shannon began to wonder if a computer could beat a human at games, such as chess. The theory uses mathematics to understand the rules governing the transmission of messages through communication systems, applicable to everything from computer code, speech and music, to the dancing of bees. The question came from Claude Shannon, inventor of ‘ Information Theory’ in 1948.
