Maybe if you have the appropriate tablebases then this position is a walk in the
park.  If you don't have them then find the aspirin.

This very instructive analysis was published by GM Pal Benko in the June 2000
issue of CHESS LIFE.  In it, he corrects the erroneous analysis of GM Jan
Timmman from the Encyclopedia of Chess Endings (1986)

[D]2B5/8/8/7p/6p1/4k1P1/3r3P/6K1 b - - 0 1


1...Rd8 2.Bb7 h4 3.gxh4 Rh8 4.h3 [4.Kg2? Kf4 5.h3 Rb8! (overlooked by Timman)
6.Bd5 Rb2+] 4...gxh3 5.Kh2 Rxh4 6.Bc8 Rh8 7.Bg4 [7.Bxh3 Kf2 8.Kh1 Rxh3#] 7...Kf4
8.Bd7 Rd8 9.Be6 Rd6 10.Bc8 Rd3 11.Be6 Rf3 12.Bd7 Kg5 13.Bxh3 Kh4 14.Bg2 Rf2
15.Kg1 Kg3 [and mate follows after] 16.Bd5 Rd2 17.Bb3 Rb2 18.Bd1 Rb1 19.Kf1
Rxd1+ 20.Ke2 Rd4 21.Ke3 Rf4 22.Kd2 Rf3 23.Ke2 Kg2 24.Kd2 Kf1 25.Kc1 Rf2 26.Kb1
Re2 27.Ka1 Ke1 28.Kb1 Kd1 29.Ka1 Kc2 30.Ka2 Re3 31.Ka1 Ra3#

This position sure taught me a lot about this type of endgame.
