Diagram 4. Tsukata(b) vs Habu(w), up to G-7a

The game, Tsukata vs Habu, took place on October 14, 1986, in the
Zen-Nippon Pro-Tournament.

G-7a was Habu's answer to the Tsukata Special. If Tsukata made
R-6d here, he would have nothing to exchange his R for, in the event of
White's Rx8h+. And another thing: Habu won't have to worry about Black's dro
p of P on 8b, if he shifts his R to, say, 7f.


Moves after the diagram: (from Black)
P-1e, Px1e;       P*1d, P*2c;        R-2e, P-1f;        R-2f,

In response to White's P*2c, Tsukata pulled his R one square back, and then
another step back alongside White's P-1f.  Smart moves.

Moves afterwards: (from White)
      R-8b;       Rx1f, P*8f;        P*8e, Rx8e;        N-7g, R-5e;
S-6h, P*1b;       P-7e, Rx7e;        Rx8f, P*8b;        K-4h,

White has gained a Pawn up to this stage, but its R is in a difficult positi
on to work effectively. All in all, Black seems to enjoy a slight advantage.
 After this, however, Habu tried hard to make the game even-positioned,
until he made a fiasco past the middlegame, which  eventually inflicted a de
feat on him.

Moves afterwards: (from White)
      P-3d;      P-9f, S-4b;      K-3i, K-4a;      R-8d, P-3e;
B-9g, R-4e;      P-5f, P-9d;      B-8h, R-4d;      S-5g, P-1c;
S-4f, Px1d;      Sx3e, R-5d;      R-8f, P-1e;      B-7i, P-6e;
K-2h, P-1f;      P*1e, P-6f;      Px6f, Lx1e;      P*1h, B-1c;
P-6e, N-3c;

The last move, (w)N-3c was the irrevocable mistake. Then followed
P*2d, P*3d;      S-2f, Bx2d;      Bx2d, Px2d;      Sx1e,
Habu's pure loss of L on 1e tolled his funeral.
