Quest of the lost systems

Chapter Two: Furibisha

Section 5: Masuda-shiki Ishida-ryu

Masuda's quest, however, did not end there. His next mission was to prove that this strategy was also valid when playing white. He again took the same strategy in the following game of meijin-sen, in which he had to play white. The whole shogi world got, understandably, quite excited about this.

The third game of Meijin-sen took place on April 30 & May 1, 1971. The diagram above shows Masuda's formation as White. Then follows: (from Black) S-4h, K-6b, P-4f, K-7b, K-6h, K-8b, K-7h, S-7b, S-4g, P-1d, P-2d, Px2d, Rx2d. Masuda's domain looks already partly crushed, but not exactly. He then proceeds as follows: (from White) +B-8h, Sx8h, R-2b, P*2c, R-1b. After exchanging Bs, he shifted his R to 2b, demanding another exchange of the big pieces, Rs. By resorting to this procedure, Masuda virtually stopped Oyama's attack on the second file, just as he had planned. Oyama avoided exchanging Rs, because his territory alone would have had a space for dropping R. So, he had to drop his P on 2c. But with Masuda's R at a safe spot on 1b, Oyama had no further means of attack. He could have dropped B at 2b, but only would have met Masuda's G-3b.
