"the maximum number of moves in a legal game is about 5000 moves, (a quick google suggested 5899" ++ 5898.5 due to the 50-moves rule. https://wismuth.com/chess/longest-game.html However, from the initial position a 7-men endgame table base draw or a prior 3-fold repetition is reached long before 300 moves.
Didn't you mean long before 30 moves?
But it's not limited by the 50 move rule because claiming is optional. And in a practical game you don't claim as soon as it's reached if you have mating material anyway (or even if you don't in many cases).
Silly people. ^
(like that!)
