The Baron 1.5.0 fails to see a win for white. After forcing g4 (The Baron wants
to play Rd7 with an evaluation of only a few centipawns more) it presents the
following line:

 18(37).  17:56.52 504289864   -0.26  h5xg4 h3xg4 f7-f5 g4xf5 g6xf5
                                      Rd2-c2 Ke5-d5 Rc2xc4 Kd5xc4 Kb1-c2 Kc4-b5
                                      Kc2-c3 Kb5-b6 b2-b3 a4xb3 Kc3xb3 Kb6-b5
                                      a3-a4 Kb5-a5 Kb3-c3 c5-c4 Kc3xc4 Ka5xa4
The Baron thinks 45..Ke6 is a little worse than 45..f5. After 44.g4 hxg4
45.hxg4:
 18(35)&   6:48.42 218768735   +0.55  g4-g5 f7-f6 g5xf6 Ke6xf6 Rd2-c2
                                      Rc4xc2 Kb1xc2 Kf6-e6 b2-b3 a4xb3 Kc2xb3
                                      Ke6-d6 Kb3-c4 Kd6-c6 a3-a4 g6-g5 a4-a5
                                      g5-g4 a5-a6 Kc6-b6 a6-a7 Kb6xa7 Kc4xc5
                                      Ka7-b7
