Thanks for the interesting post. I was looking to see if black could have played
an alternative line to keep the pressure on white.
5R2/7k/3P4/6p1/4pp2/5p1K/5P1P/6r1 b - -
id cubebox - roboElvis; bm Rd1;
I think if a program were to see that deeply into this position at move
42 instead of e3 it would play Rd1. Then if 43. Kg4 Kg7 44. Rf5 Rg1+
Rebel Century liked 42. e3 with a plus 10 eval for black as well.
It's a quirky position for chess programs to figure out. The other thread,
called a "hard endgame", is also giving programs the fits.
