4. ... P-3f 5. Px3f Rx3f 6. R-3h (uc) White loses tempi, but the position is unclear.
6. R-8h: Double Ranging Rook. It accounts for about 3 % in professionals' games.
6. ... P-7d White could have built Yagura.
11. ... S-3c: Defense against Black's S-3g S-4f. P-4f S-4c or P-5f S-5c are common moves.
17. G4i-4h S-8b: Twin-Golds Castle. Commonly used in Double Ranging Rook.
19. R-8f, then P-2f P-3f was also an effective positioning.
22. P-1e Px1e 23. Lx1e P*1d 24. Lx1d Rx1d 25. Bx3c+ B-2d (=/+)
22. S-4e Nx4e 23. Bx1a+ (I don't know which has an advantage in this position. )
