2. ........ K - B 5
3. K - B 2 K - Kt 5
4. K - Kt 2 K - R 5
5. K - Kt 1 K - R 6

The first part has been completed.

The second part will be short and will consist in advancing the R P up the K.

6. K - R 1 P - R 4
7. K - Kt 1 P - R 5

This ends the second part.

The third part will consist in timing the advance of the Kt P so as to play P - Kt 6 when the White King is at R 1. It now becomes evident how necessary it is to be able to move the Kt P either one or two squares according to the position of the White King, as indicated previously.[[2]] In this case, as it is White's move, the Pawn will be advanced two squares since the White King will be in the corner, but if it were now Black's move the Kt P should only be advanced one square since the White King is at Kt 1.
