So the solution must be 1...b5! and if 2.a5 (2.axb5 Kc7 followed by Kb6, Kxb5, etc.), b4! 3.Kc2 Kc6 4.Kb3 Kb5. I haven't worked it out until the end, but I assume that Black eventually wins through zugzwang since White must worry about Black's protected passed e-pawn forever. But even if White turned out to have some weird draw, Black MUST play this way, since otherwise White sets up a blockade and draws.Frederick Rhinehttps://www.blogger.com/profile/11728232939607408071noreply@blogger.com
