Solution
Spoiler (click to reveal)
1. e5:b2 (the crucial point) d5:b2 (White is still two pieces ahead, but has a bad position.)
2. b5:b2 b1-c2
3. b6:c2 (any captures would be good) a2:b2
4. c2:b2 a1-a2 (of course, a1-b2 is just as hopeless)
5. b2:a2. - Black wins by one point.

If 1. e5:d5? b2:d5,
2. b6-c5 d5:c5
3. b5:c5 b1-c2
4. c5:c2 a2:c2. - White wins by two points.

1. e5:b2 is thus worth three points.
