White to Play - Win
1.a6 Rd1+ In the note 1...Ra1 2.c7! Rd1+ 3.Ke7 (Fine's concept work if White controls the back rank 3.Ke8 Re1+ 4.Kf8 Rf1+ 5.Kg8 and wins) 3...Rc1 4.Kd7 Rd1+ 5.Ke6 Re1+ 6.Kf6? allows Black to draw 6...Re8! (instead of Fine's 6...Rf1+? when White can retrace his steps, but not Fine's 7.Kg6? when 7...Rf8! draws in similar fashion (instead of Fine's 7...Rc1?) ) 7.a7 Kf4 8.Kf7 Ra8 9.Ke6 Ke4 10.Kd6 Kf5! 11.Kc6 Ke6! 12.Kb7 Kd7! 13.Kxa8 Kxc7 2.Kc8 Ra1 3.Kb7 Fine gives a draw in Variation A after 3.c7 but White still wins 3...Kf4 4.Kb7 (4.Kd7 Rd1+ 5.Ke7 Re1+ 6.Kf8 Rh1 Fine's 7.a7? allows a draw, but White again can retrace his steps by (7.Ke7) ) 4...Rb1+ 5.Kc6 Rc1+ 6.Kb6 Ke5 7.Kb7! (instead of Fine's 7.a7? Kd6! 8.Kb5 Rb1+! 9.Kc4! Ra1! which is the same position as after 11...Kd6! in the main line below) 7...Rb1+ 8.Kc6 Rc1+ 9.Kd7 Rd1+ 10.Ke8 Rc1 11.a7 3...Rb1+ 4.Ka8 Rc1 5.a7 Kf4 6.Kb7 Rb1+ 7.Ka6 Ra1+ 8.Kb6 Rb1+ 9.Kc5 Ra1 10.c7 Ke5 Fine's 11.Kc4? allows a draw. All other king moves win. 11...Kd6! instead of Fine's 11...Ke4?, this is the same draw Fine demonstrated in Variation A. 12.c8Q Rc1+! 13.Kb5! Rxc8! 14.Kb6! and the rook will soon be traded for a newly promoted queen.
