Crafty wins with 41.Ke4!

[D] 8/8/3k2p1/7p/P1P1K1p1/8/7P/8 b - - 0 1

This prevents the black pawns from advancing.  Then white deflects black's king
with the a-pawn, after which the c-pawn, supported by white's king, can queen
before the black pawns can.  One possible continuation:

41....Kc6 42. a5 Kc5 43. Kf4 Kc6 (43...Kb7 44. c5 Kb8 45. Kd6 h4 46. c6 g3 47.
hg h3 48. Kd7 h2 49. c7+ Ka7 50. c8=Q h1=Q 51. Qc7+ Ka8 52. Qc6+ Qxc6+ 53. Kxc6
and white wins) 44. Ke5 Kc5 45. a6 Kb5 46. c4+ Kxa6 47. c5 and the c-pawn will
queen and stop blacks pawns.
