What is the maximum number of moves there can be in a game of chess? You have to consider the rule if there is no capture of any piece after 50 moves, the game is drawn.
16 pieces * 50 moves without capture * (8 pawns to move * 6 steps to get across) = 38400 moves theoretically. But I bet I am far from the truth now and just drank too much of that fruit juice.
