III Plate 35 (C) The following stones are on the board: White, B 16, C 14, E 15; Black, C 17, D 16, E 16, G 17. If White has the move, it makes a difference of seven "Me." The following stones are on the board: White, B 8, C 7, C 8, D 6, E2, E 6, F 3, F 5; Black, B6, B7, C 6, D 2, 3, 4, 5. If White has the move, it makes a difference of four "Me." WHITE 1. B 4. This stone is sacrificed, but there is no loss because it is so threatening that Black must play twice in order to make his position secure, meanwhile White advances on line A. BLACK 2. B 3. Black's best move because it defends the connection at C5, and also prevents White from trying to connect at D 1. 3. A 7. White gains one "Me" 4. A 6. The following stones are on the board: White, M 16, M 17, M 18, N 16, Ο 15, P 14, R 14; Black, N 17, N 18, Ο 16, P 16, Q 16, R 16. If White has the "Sente," it makes a difference of six "Me." The following stones are on the board: Black, M 2, M 3, N 3, N 4, O 4, Q4, R4, S 4; White, L 3, N 2, O 2, O 3, P 3, R 2, S 3, R 6. Black has the "Sente" and gains nine "Me.” The following stones are on the board: Black, B 17, C 17, D 16, G 17; White, B 16, С 13. BLACK 1. B 14. This move is really "Go te"; that is to say, White is not forced to reply to it, but it is very advantageous for Black, as it effectively separates White's two stones. 3. B 15. The white stone at B 16 is now hopeless. WHITE 2. C 14. C 15 is not so good. Black has given up the "Sente," but has gained considerable ground. VIII Plate 36 (D) The following stones are on the board: Black, C4, D 4, E 4, C 7; White, C 3, D3, E 3, F 3. Black has the move. 1. B 3. 3. В 4. BLACK WHITE 2. B 2. These moves seem obvious, but the importance of Black's opportunity is likely to be underestimated; Black gains about eleven "Me" by this play. If the opposing lines extend one space nearer the edge of the board, the territory gained by a similar attack is not nearly so great. IX Plate 37 (A) The following stones are on the board: White, M 16, Ν 16, Ν 18, Ο 17, P 18, Q 17, 18; Black, N 15, Ο 15, 16, P 16, 17, Q 16, R 12, R 17. White has given up the "Sente," but these moves make a difference in his favor of about fourteen "Me." |
