5. A 8.

6. C 4. Necessary because the connection at C 5 is now in immediate danger, but Black thereby fills up another of his "Me," and White retains the "Sente."

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."

The following stones are on the board: Black, M 2, M 3, N 3, N 4, O 4, Q 4, R 4, S 4; White, L 3, N 2, O 2, O 3, P 3, R 2, S 3, R 6.
