When two engines play against each other in a game of chess, when is it appropriate to declare a draw when clearly no progress is possible?
8/6k1/8/R3K2p/2r3p1/6P1/7P/8 w - - 0 2
This was a position reached against two engines I am having compete. It has been going on for a while and I doubt a win is possible. Repetition seems like a while away, and I think the fifty-move rule only works if a player requests for it (these engines don't do that). I can't even declare this a draw by endgame tablebases because it has 8 pieces.
