So I decided to figure this out to see what the max number of moves you could make in a game without it being considered a draw, that is, until the 50 move rule or the three repeating move kicks in.
Assuming you don't repeat any moves three times, you would have 50 moves before a pawn would have to be moved or a piece captured so we will move a pawn. It is also possible for each pawn to move 4 places before it reaches the other pawns so we have 16*4*50 = 3200 (16 pawns, 4 moves, 50 move max).
Now we can also reset the counter by capturing. There are 30 pieces that can be captured so we have 30*50 = 1500. This is assuming the queen or rook is the last piece each side has as to not draw for lack of material.
So we would have the original 50 moves plus the 16 moves plus the 30 moves to reset the counter so 96 moves.
We have a grand total of 4796 moves before a chess game would draw. I would imagine it would be possible to get higher than that with creative manipulation of the pawns to the 7th and 8th rows but that would be for another time.
