I don't think this is correct ... :((
The variation you give is losing for black ... to the best of
my analysis.
46. Rb1 Kc2 47. Rxb2 Kxb2 48. Kf5 d2 49. Kxg6 d1Q 50. h8Q+ Kb3
51. Qh3+ Kb4 52. Kh7  and now how do you stop this white pawn.
it normaly takes me just another 5 moves and then at depth 13ply
crafty shows 6.8 ...

It seems white are wining ... I use crafty 16.something
and I let it think for about 1 hour then I make the move.
The problem with blacks position is that if white takes the pawn
on b2 then the white pawn on g5 is tough to stop.
42. Kg2 b2 43. Kf3 Kc3 44. h7 Ng6 45. Ke4 Kc2 46. Rf1 b1Q
47. Kf5 d3 48. Kxg6 d2 49. h8Q d1Q

Analyze this position ... it usualy takes another 7-10 moves before
crafty goes +6.8 ...

BTW I don't have tablebase so I might be missing something!
