For the people who are saying that players won't agree to a draw in a position like this:
All the player who wants the draw would have to do is move their king around randomly without even thinking. It wouldn't exhaust anyone. I'd be laughing at my opponent the whole time as he makes random moves also! I'd be happy to do it with 1 sec on clock w/ 5 sec delay.
This endgame you can lose only if you are completly in full cooperation with the opponent.
For example.
Or if black wants to lose.
Then it's getting ridiculous. UR gonna say, ohh 100 moves for Q vs R, 200 moves for 2 bishops vs knight, 150 moves for 3 minor pieces vs rook...etc. Who's gonna keep track of that? Just make it 1000 moves for ALL endgames or NOT AT ALL!
