Probably quite easy to write a world champion longest game creator. Self play, with win=loss, draw=loss, loss=loss, everything else scores 0.5 + 0.01 * moves since an irreversible move.

Maybe creating a long game creator is 'easy'. But probably one that generates the theoretical longest one not. Always difficult becoming a world champion.

Just post longest game and we'll see if it can be beaten.

There will be an almost infinite number of longest game. Length = 99 x maximum number of irreversible moves. 29 piece captures + max number of possible pawn pushes.

Don't understand. Where does 99 come from.
