The following stones are on the board: White, M 16, M 17, M 18, N 16, O 15, P 14, R 14; Black, N 17, N 18, O 16, P 16, Q 16, R 16.

If White has the “Sente,” it makes a difference of six “Me.”

1. N 19. 2. O 18. Black cannot stop the invasion at O 19, as White would then play at O 18 and kill the black stones on line N.
3. O 19. White pushes his invasion farther. 4. P 19. Black can now arrest the advance.
5. M 19. 6. P 18.

White retains the “Sente.”
