White draws


While the black king is in the (green) square and can snap up the white c-pawn anytime, the white king is out of the (red) square, unable to catch the black h-pawn. Reti makes the study work, blending both green and red squares into a beautiful solution. Can you find how white draws?

SOLUTION:
1.Kg7! (The king has to climb up diagonally to reach one of the two squares.) 1...h4 2.Kf6! Kb6 3.Ke5! (The diagonal journey is successful. The white king can either help his own pawn or catch the black one.) 3...h3 (After 3...Kxc6 4.Kf4 draws.) 4.Kd6 h2 5.c7 h1Q 6.c8Q draw.

White draws

SOLUTION:
(With the first three moves, white threatens to advance his a-pawn, forcing black to react.) 1.Kc8! (After 1.a6? Kc6 2.Ke7 h5 black wins.) 1...Kc6 2.Kb8! (After 2.a6? Kb6 3.Kd7 h5 black wins.) 2...Kb5 3.Kb7! Kxa5 4.Kc6 (As in Reti's study, the diagonal walk saves the game.) 4...h5 5.Kd5 the white king is in the square and catches the black pawn. Draw.

Kd4 4.a6 Ke3 5.a7 f2 6.Kg2 Ke2; or 3.a6? Kd2 4.a7 f2 5.Kg2 Ke2 black draws.) 3...Kd4 4.a6 Ke3 5.Kf1! (The black pawn is stopped and the white pawn queens.) 1-0
