• 10. ... R-8e: Chuza-Style Side Pawn.
• 14. ... P-7d: Up to here, completely same as the 40th Oui match round 2.
• 15. S-3g: K-6h formation seems to be better for this attack. Protect 4i-G with 5h-K?
• 15. ... P-5d: Restrain Black's B*5f.
• 18. ... Px7f: Newspaper says +/- in this position. White has a weak point at knight's head.
• 22. P*7g: Dubious move. P-6f would have been better?
• 24. ... P*8f: Good move. If 24. Px8f then 24. ... Rx8f 25. P*8g Rx7f 26. P*7g Rx4f 27. Px4f N6ex5g+ 28. Sx5g S*4i 29. Kx4i Nx5g+ (-/+).

12th Ryuo Match: Round 1

• October 14-15, 1999
• 6th dan SUZUKI Daisuke 0-1 Ryuo FUJII Takeshi
• Black's Fourth-File Rook P-6e P-7e Formation

1. P-7f P-3d 2. P-6f P-8d 3. R-6h S-6b 4. K-4h K-4b 5. S-3h K-3b 6. K-3i G6a-5b 7. S-7h P-5d 8. G6i-5h S-5c 9. P-1f B-3c 10. B-7g K-2b 11. P-4f P-4d 12. P-6e P-8e 13. P-7e G-4c 14. P-3f R-7b 15.

• 3. R-6h: Suzuki had declared that he would range rook in all the games of this Ryuo match.
• 4. K-4h: Suzuki doesn't use Fujii system.
• 5. S-3h: Suzuki's favorite is Fourth-File Rook Bear-in-the-Hole...?
• 12. ... P-8e: It prevents Black's R-6f - R-8f after P-7e.
• 13. P-7e: I think it questionable. This P-6e P-7e formation has an aim of eirly fight before the completion of White's castle, but White needs only two plies to complete the castle from this position.
• 14. R-6f P-4e 15. R-7f (15. Px4e Bx6f 16. Bx6f N-3c (=/+)) Bx7g+ 16. Nx7g (16. Sx7g B*7h (=/+)) B*8h (=/+)
• 15. P-8f P-7d (15. ... Px8f 16. R-6f (+/=)) 16. Px8e Px7e (uc)
• 16. N-3g: Usually White's castle is defective in this position and 16. R-7h (if 16. ... P-7d then 17. Px7d Rx7d 18. B-8h to rook exchange (+/=)) is a common move. But in this case White's castle is complete and rook exchange does not give an advantage to Black.
• 17. ... Rx7d: -/+.
