What is the line to draw or lose for black?
Here is the position after moving Kd5 and analysis by Chess Tiger:
[D]8/1R5P/8/p2k4/4pK2/2p5/8/7r w - - ce -348; acd 15; acs 1; pv Rf7 a4 Rc7 Rh6
Kg5 Rxh7 Rxh7 e3 Rd7+ Ke4 Re7+ Kf3 Rf7+ Kg2 Kh4 e2 Re7 Kf2 Rf7+;|Rb7f7
and Yace says this:
8/1R5P/8/p2k4/4pK2/2p5/8/7r w - - c0 "after Kd5";
