Now it would not do to play K - B 7, because Black would play K - Q 3, and White would have to bring back his King to protect the Pawn. Therefore he must continue.
7. P - K 5, K - K 1.
Had he moved anywhere else, White could have played K - B 7, followed by the advance of the Pawn to K 6, K 7, K 8; all these squares being protected by the King. As Black tries to prevent that, White must now force him to move away, at the same time always keeping the King in front of the Pawn. Thus:
8. K - K 6.
P - K 6 would make it a draw, as Black would then play K - B, and we would have a position similar to the one explained in connection with Example 5.
8...K - B 1; 9. K - Q 7.
King moves and the White Pawn advances to K 8, becomes a Queen, and it is all over.
This ending is like the previous one, and for the same reasons should be thoroughly understood before proceeding any further.
