1000th move in a game


if neither player claims a draw then the game can go on infinitely, assuming they are not allowed to do that, i remember someone saying the longest possible game was 5000ish moves, but they didnt show an example so idk if it is true
Recall that a pawn push or a capture of a piece always resets the 50-move counter.
Technically, there can in theory be a maximum of up to 96 pawn moves (6 x 16 = 96), including captures (a few pawns must have made some captures or else the pawns will be all be jammed).
There can be up to 30 captures made, but some of these are done by pawns. These pawns need to make minimally four captures (eg a4xb5, c4xd5, e4xf5, g4xh5) to clear up paths for the opposing pawns to make promotions.
I suspect that the maximum possible theoretical number of captures is therefore (96 + 30 - 4) x 50 + 50 = 6150 moves. The final "+50 moves" is to account for the first 50 moves, though this runs into the risk of repetition of positions.
