Black to play - Draw

1...b4 2.Rh8+ Kg7 3.Rb8! a5 4.Kh2 There are problems in both of Fine's lines after 4.g4
a) 4...Rd2 5.Rb5? (5.h5 a4 6.g5 a3 7.h6+! Kg6 8.Rb6+ Kxg5 9.h7! holds) 5...a4! (Instead of Fine's 5...Rd4?) 6.Rxb4 a3! 7.Ra4 a2! and Black wins.
b) 4...Rb2 5.g5 a4 6.h5 a3 7.h6+ Kg6 8.Rb6+ Kh7 9.Rb7+ Kg6! (instead of Fine's 9...Kg8?) 10.Rg7+ Kf5! 11.h7 a2! 12.Ra7! Rb1+! 13.Kg2 Rb2+! with a draw. If the White king leaves the kingside, Black plays his rook to the h-file to stop the h-pawn.
