Black only draws with 111...Ke4? 112 Kf6(f7) Rf1+ 113.Ke6 Ra1 (113...Rg1 114 Kf6 Kd5 115 g6 Kd6 116 g7=)
114 g6 Ra6+ 115 Kf7 Kf5 116 g7 Ra7+ 117 Kf8 (117 Kg8! Kg6 118 Kh8=) 117...Kf6 118 g8N+.

Now White’s king is unable to “shoulder-block” its Black colleague. For this purpose, even a tempo is not too great a sacrifice!

Can White win?

With accurate defense, the position is drawn.

In the game, Black erred with 3...Ra1?, and after 4 Rc8! (but not 4 Re8? Ra6+! =) 4...Ra6+ 5 Rc6 Rxa7 6 Rc7+ Rxc7 7 Kxc7, White controlled the distant opposition, which was then easily converted to the close opposition: 7...Kh7 8 Kd7! Kg6 9 Ke6 Kg7 10 Ke7 Kg6 11 Kf8, and Black resigned.

4 Ke6 Ra1 5 Rd8 (5 Re8 Ra6+! 6 Kf5 Rxa7 =) 5...Rxa7 6 Rd7+ Rxd7 7 Kxd7 Kh7!=. Black is saved only by the distant opposition - and not by the close opposition: 7...Kf7? 8 Kd6 is zugzwang, and it is White who takes the opposition.

The Black rook stands behind the passed h-pawn; but since White’s king has already arrived to blockade it, the pawn can only be employed as a distracting force. Black must initiate active operations on the opposite wing.
31...Ke6?! is useless after 32 Re1+ (Black cannot allow the White rook to reach the 7th). And after 31...Rh7?! 32 Kh3, it’s not easy to make further progress.

The pawn ending is lost: 33 Rxc7 Kxc7 34 Kg3 Kd6 35 Kh4 Kd5 36 Kxh5 Kd4, and wins. If 33 Rf8, then 33...Rc2+.

Black is now winning: the king goes to d3, preparing Rc2.

34 a4?! (this move, weakening the queenside pawns, actually makes Black’s job easier) 34...Kd4 35 a5 Kxd3 36 Rf3+ Kc2 37 b4 b5!
38 a6 Rc4 39 Rf7 Rxb4 40 Rb7 Rg4+ 41 Kf3 b4 42Rxa7 b3 White resigned.
