Section 5: Masuda-shiki Ishida-ryu

Masuda's Ishida-ryu: gote version (3)

After Masuda's R-1b followed : R-2f, G-3b, P-3f, Px3f, Sx3f, P*2b, Px2b+, Rx2b, P*2e, S-4b, G-6h, P-5d, P-1f, B*5c. (See Diagram below)

+--------------------------------------------+       White in hand:
| wL | wN |    | wG |    |    |    | wN | wL |  a   +------------------+
+--------------------------------------------+      |    2P            |
|    | wK | wS |    |    | wS | wG | wR |    |  b   |                  |

|    |    |    |    | wP |    |    |    | wP |  d

|    |    |    |    |    |    |    | bP |    |  e
+--------------------------------------------+
|    |    | bP |    |    | bP | bS | bR | bP |  f
+--------------------------------------------+
| bP | bP |    | bP | bP |    |    |    |    |  g
+--------------------------------------------+      Black in hand:
|    | bS | bK | bG |    |    |    |    |    |  h   +------------------+
+--------------------------------------------+      |   B, P           |
| bL | bN |    |    |    | bG |    | bN | bL |  i   |                  |
+--------------------------------------------+      +------------------+

Then continued as follows (from Black) :

R-2h, B-6d;     G-3h, Bx4f;    N-3g, P*2c;     S-7g, P-4d;
S-6f, S-4c;     G-4g, B-6d;    P-5f, S-3d;     P*3e, S-4e;
P-5e, Sx3f;     Gx3f, P*3h;    R-2i, G-4c;     P-2d, Px2d;
S*6e, B-3a;     Px5d, S*4g;    G-4f, S-4h=;    G-3f, P-6d;
S-5f, P-3i+;    P*2c, R-3b;    R-2h, +P-4i;    K-8h, P*3d;
Px3d, P*3e;     Gx3e, Sx3g=;   R-2g, S-4f=;    Gx2d, B-1c;
G-7h, N*8d;     B*7i, Nx7f;    K-7g, P*2f;     Rx2f, ???

Excuse my long citation. Masuda made a develishly clever move at the end (marked ???), which set the game in his favor. Would you guess what that move was? Check out the next page to find out. Oyama, however, was known to be a tenacious player. He hung on till the 210th move, and finally bowed to Masuda.

Masuda-shiki Ishida-ryu was a challenge to a common belief that furi-bisha was a passive strategy. And Masuda certainly made his point.

Thus, Masuda's Ishida-ryu had its day, becoming a pet strategy among shogi fans for a certain period, and even to this day we still can see some people like to use it, but not among professionals. Why? The clue lies in the 6th game of the same meijin-sen series.
