Diagram 50c ‒ Black to play

J. Horvath - Marciano

Izmir ECC 2004

When the pawn is further back, a win is only possible if the enemy king is cut off by almost the whole width of the board.

1...Kg6

A good move, as White was threatening to establish a winning position by playing Rg3.

2 Rf3

White cuts off the king as far away as possible, but even this is insufficient for a win.

2...Ra8 3 Ke5 Ra5+ 4 Kd4 Ra8 5 Kc5 Kg5 6 Kb4 Rb8+ 7 Kc4 Rc8+ 8 Kb3 Rb8+ 9 Ka2 Ra8 10 Rf2 Kg6 11 Rf1

White’s plan is to play his king as far up the board as possible, and then support the pawn from behind with Ra1.

11...Kg5 12 Kb3 Rb8+ 13 Kc4 Ra8 14 Kb4 Rb8+ 15 Kc5 Ra8 16 Ra1

Threatening to win by pushing the a-pawn, so Black’s king must run to the queenside.

16...Kf6 17 a4 Ke7 18 Kb5

After 18 Kb6 Kd7 19 a5 Rb8+ White is virtually forced to play his king in front of the pawn, which allows Black an easy draw.

18...Kd8 19 a5 Kc8?

19...Kc7 20 a6 Rh8 leads to a draw.

20 a6 Kb8

Or 20...Kc7 21 Rc1+ Kd6 22 Ka5 Kd7 23 Rh1 Kc6 24 Rh7 Rg8 25 a7 and White wins.

21 Kb6?

Missing 21 Rh1! Ra7 22 Rh8+ Kc7 23 Rg8 Kd6 24 Kb6, winning. The move played allows Black to draw by a neat stalemate trick.

21...Ra7 22 Rh1 Rb7+! 23 axb7 ½-½
