I hope this article on how many possible moves are in Chess helped you. There is nearly an infinite amount of moves, sequences, and combinations that can be played. Which is one of the reasons why the game of Chess is so amazing and looked up to by intellectuals.

It brings upon an element of fascination. The possibilities are endless. Edit: I'll leave the original as it stands, but want to add a correction thanks to Mike Dunlavey's comment. I misread the question and thus if the question is, indeed, asking whether games lasting 40 moves or less I read 40 moves or more is greater than the number of atoms in the universe, I'm switching my answer to disagree. Thus the number of atoms is greater. First, Wiki provides this figure on the number of atoms in the universe:.

Next, Wiki provides the Shannon number as the number of possible chess games that can be played:. Lastly, Wolfram Mathworld provides a figure for the number of games less than 40 moves :.

I see some other answers have come in while I've been typing. In that case, we look at:. Just wanted to spell out why I think the question is slightly different than just comparing of atoms and of all possible chess games.

The accepted answer is wrong, due to the fallacy of accepting a link to a another website as the truth, rather than actually doing the math.

The Beeler reference itself is very clear that it means positions, not games:. Shannon really wrote in XXII. In typical chess positions there will be of the order of 30 legal moves. The number holds fairly constant until the game is nearly finished as shown in fig.

This graph was constructed from data given by De Groot, who averaged the number of legal moves in a large number of master games De Groot, , a. Thus a move for White and then one for Black gives about possibilities. A typical game lasts about 40 moves to resignation of one party. This is conservative for our calculation since the machine would calculate out to checkmate, not resignation. Another equally impractical method is to have a "dictionary" of all possible positions of the chess pieces.

For each possible position there is an entry giving the correct move either calculated by the above process or supplied by a chess master. At the machine's turn to move it merely looks up the position and makes the indicated move. The number of possible positions, of the general order of 64! In chess , "40 move game" means each player moves a piece 40 times: ply or 80 half moves. Thus, after 20 moves in a chess game, 40 plies have been completed—20 by white and 20 by black.

So for a 40 move game, if it is approximated that there is some constant c number of legal half-moves, the approximation of the number of 40 move games is of the form:. So as long as "c" is greater than 10, the number of 40 move games is greater than the number of atoms in the universe. For example, there are 20 possible first half-moves 16 pawn moves and 4 knight moves , and 20 possible second half moves.

So, yes, there are more exactly 40 move half move games than the number of atoms in the universe. Also, here is someone who tries to explain it more clearly. Sign up to join this community.
