[D]2b5/8/2kBp1p1/p2pP1P1/1PpP4/1p4K1/1R3P2/8 b - - acd 21; acn -772411416; acs
30001; ce 281; id "WAC.230 after Rb4 cxb4"; pv a4 b5+ Kxb5 Ba3 c3 Re2 Kc4 f4
Kxd4 f5 exf5 e6 Kd3 Re1;

Here is the pivotal move (as demonstrated by Alex Szabo), and shows that Re2
probably *is* better than Rb1, which was actually played in the game:

[D]2b5/8/4p1p1/1k1pP1P1/p2P4/Bpp3K1/1R3P2/8 w - - acd 19; acn 320124277; acs
7201; ce -217; pv Re2 Kc4 f4 Kd3 Kf3 Kxd4 f5 Ba6 Rh2 exf5 e6 Bb5 Kf4 Be8 Rh1; id
"WAC.230 after Rb4 cxb4 a4 b5+ Kxb5 Ba3 c3";

[D]2b5/8/4p1p1/1k1pP1P1/p2P4/Bpp3K1/5P2/1R6 b - - acd 18; acn 180000563; acs
7202; ce 373; pv Kc4 Rc1 Kxd4 f3 Kd3 Rb1 d4 Kf4 Kc4 Rc1 Kd5 Rb1 d3 Rc1 d2 Rxc3
d1=Q Rxc8; id "WAC.230 after Rb4 cxb4 a4 b5+ Kxb5 Ba3 c3, and then the game
continuation Rb1 instead of Re2";

[D]2b5/8/4p1p1/3pP1P1/p1kP4/Bpp3K1/5P2/1R6 w - - acd 17; acn 85024238; acs 7201;
ce -317; pv f4 Kxd4 Re1 Kc4 f5 exf5 e6 b2 e7 Bd7 Kf4 Be8 Ke5 Kb3 Bxb2 cxb2 Kxd5
a3 Rb1; id "white is still toast at this point, I think."

So the real question is, can black win after white responds with Re2 after the
sequence Rb4 cxb4 a4 b5+ Kxb5 Ba3 c3
?
