This is the same position as the previous example - The Lucena Position but with Black to move
1...Ra8+
2.Kd7
Ra7+
3.Kd6
Ra6+
4.Kc7
Ra7+
with a draw but if the pawn had been on d7 and all pieces except the black rook are shifted a single file to the left White would win as the rook is not remote enough for the side checks to continue - the distance has to be at least 3 squares for White to win. Black should always position the Rook on the long side and the King on the short side where the Board is divided into two parts by the White pawn. *
