What's the current rule of chess regarding draws other than a stalemate or having a King bishop(or knight) vs lone King(automatic draw since they can't checkmate the king)?
Like when there's a threefold repetition, is that a mandatory draw or do at least one of the players must claim a draw?
What about the 50 move rule after there's only the King vs King + another piece(or more), if no one invokes these "rules", can the game go on forever?
I'm just wondering about whether there's a maximum theoretical number of moves in a game. People have said that it's 5949 moves, but I've never seen a proof of this and how they came to that number. How did they get that number and is it right?
tldr; if I didn't make sense up there, just wanted to talk about the maximum theoretical number of moves in a game and was wondering how the official draw rules affected that.
