Protect the c-pawn and then just advance the pawns. Sac a pawn(s) when necessary to divert the White King to allow Black's King to advance to d3 or e2. As in a line as shown below: 8.Bc2+ Ke5 9.Kd3 Bb2 10.Kc4 b5+ 11.Kxb5 Kd4 12.Kb4 Ke3 13.Bd1 Kd3 14.Kb3 a5 15.g4 a4+ 16.Kxa4 c2 Something similar to this should win easily for Black! Brian
