Diagram White has an extra pawn, but his king cannot reach the queenside and the black Rd5 is holding the b- and g-pawns.

39.Re6
With the obvious idea of Re5, either exchanging the rooks or winning a second pawn.

39...Kd7 40.Re5 Rxe5 41.fxe5 Ke7
[41...Ke6 42.Kd4 wins easily because white will gain access to the d5-square]

42.Kd3
nicely played. Now on ...Ke6 Kd4 wins easily.

42...Kd7 43.e4! f4
[43...fxe4+ 44.Kxe4 with an easy win.]

44.Ke2 Ke6 45.Kf2
[45.Kf3?? Kxe5-+ ]

45...Kxe5
[45...Ke7 46.Kf3 Kd7 47.Kxf4 Ke6 48.Ke3+- ]

46.Kf3 1-0
