Diagram 9. Habu vs Maruyama, up to K-4a
Major moves prior to the diagram 9 were P-1f, P-1d followed by S-3h,
then P-7f after seeing White's P-6d. White chose its R to stay on 8f, thus
the diagram 9 is quite like the diagram 8.
The game was played by Yoshiharu Habu(b) and Tadahisa Maruyama(w) on 10th,
Feb., 1992 (NHK TV tournament), which should be a good example to prove
the point I was about to refer to. The Tsukata Special inspired an idea
of parsimony of moves into the hineri-bisha opening. In this game, the hineri-bisha
side, Habu, opened fire at this moment.
Moves after the diagram: (from Black)
P*2d, Px2d; Rx2d, ....
The idea is exactly that of the Tsukata Special: By P drop on 2d, Black
schemes of taking P on 6d. If White makes S-6c, Black attacks along the
first file, P-1e, Px1e, P*1c.
Moves afterwards: (from White)
.... P-3d; P-1e, P*2c; Rx3d, B-4d; Px1d, S-3c;
R-3f, S-6c; P-1c+, Nx1c; P*2f
