IMHO the position is already dead draw in move 170 and if you would
feed Crafty with possible lines back and fourth I am sure he will
see it too...
The Black K can go to g7 and force the W rook to let him out but then
he watches the h-pawn when Black K goes until h2! but then he will be
locked again as the W rook defends simply the g-file and there is no
way than to reach a 5 piece draw rook endgame.
