  > if anyone doesn't capture or move anything in 50 moves its an draw You didn't quite state that right--every move something moves, so it is not possible to go 50 moves without moving anything. :-) The rule is 50 moves without a pawn moving or anything being captured. Also, it can be a draw, but it does not have to be. When the last 50 moves have been without a pawn move or a capture, the player on the move can claim a draw if he wishes, but does not have to do so. Recently, FIDE added a 75 move rule. It is similar to the 50 move rule, except that it is a draw even if both players wish to continue the game. (They also did a similar thing with the 3-fold repetition rule, which like the 50 move rule is only a draw if a player claims it. There is now a 5-fold repetition rule that draws even if neither player wants to claim a draw).

    Also, the reason it is 50 moves <em>without a pawn move or capture</em> is because both pawn moves and captures are irreversible. In fact, the only irreversible move that doesn't reset the 50 move rule is castling (or losing the right to castle), as having the ability to castle technically changes the position.
