  1 Rc4 and:

  A: 1…Kd6 2 Nf5 Ke5 3 Rc1 and white stops the pawn and keeps black’s knight en prise. Should be sufficient for victory.

  B: 1…Kb5 (Kb6 2 Nd5 wins) 2 a4
  Kb6 3 Nd5 Ka7 4 Rc1 and white’s advantage should be enough to win.

  Insufficient for victory is:
  1 bc6?! g1=Q 2 Rc4 Kd6 3 c7 Qf1 4 Kc3 Qc4 5 Kc4 Kc7 and it is not clear that White can win.

  Dear Susan,
  This one is really beautiful
  The idea is extraordinary :
  1)Rc4+ Kxb5
  2)Nxc6! g1=(Q)
  3)Na7+! Qxa7 {if 3)… Kb6 then 4)Nc8+ wins}
  4)Rc8! White wins

  The line given by the fourth poster wins beautifully although it seems he/she forgot the intermediate 4 a4+ Kb6 and only then 5 Rc8. Who could have visualized the Queen being trapped on a7?!! I think my line still wins although it is not as efficient or beautiful.
