How to Play against Mino Castle on the Left Side

If you love swinging Rook and offensive ideas, It would suit you to play Ishida-style opening.
The kernel Ishida idea is to place your Rook on 76 and make it easy to activate your left Knight. In fact nothing is as important as Activating the Knight wherever you swing your Rook on the left!
You play the opening like thus:


▲P-76 △P-34 ▲P-75


... △S-62 ▲P-66 △P-64 ▲R-78 △S-63 ▲K-48 △P-84 ▲G69-58 △K-42 ▲S-38 △P-85 ▲R-76

* No need too afraid of △P-65~△B*28 here because after there is counter attack ▲B*55! △N-33 ▲P-74! The line well appears on the board.


... △S-32 ▲K-39 △K-31 ▲S-68 △G61-52 ▲S-67 △B-33 ▲B-77 △K-22 ▲P-16 △P-14 ▲S-56 △P-24




This position, including similar instances, has been played again and again between masters, and for a long time this Left-Mino castle defense regarded as nemesis of Ishida-style.
They find a very natural move such as ▲K-28, ▲S-45, ▲P-65, ▲P-96, and ▲P-46... leads them a little bit disadvantaged finally. Therefore Ishida-style was once on the edge of extinction.

However, the surprising idea for which we all had been fall occurred recently.
Activate your full imagination and show next more than 5 Moves to put White on crisis!



This article is based on a game played last winter by masters, MIYAMOTO Hiroshi(Black) and NAGASE Takuya.
If you register, the full game score and Japanese analysis are available here.

Now, the game progressed thus:

▲P-26 △P-54 ▲P-25!! △Px25 ▲N-17!!


Did above occur to you? I couldn't. And at my first glance, I suspected of my pareidolia.
Surprisingly, now it's too late for White to prevent Black's diagonal attack out of sending Bishop away from 33 by the Knight.
See how the game progressed:

...△P-44 ▲P-65 △G-43 ▲P-46 △P-45 ▲Px45 △Bx77 ▲Nx77 △N-33

* If White put Bishop on 78 instead, then ▲P-44 △G43-42 ▲Px64 △Bx87+ ▲B*98!... Black is of advantage.


...▲P-44 △G43-42 ▲Px64 △Sx64 ▲P-74 △P-55 ▲S-65 △Sx65 ▲Nx65 △R-62 ▲B*54 △P*48 ▲G49-59 △R-64 ▲Bx81+ △Rx65 ▲+B-54 △R-61 ▲S*24... +/-


I hope you to analyse the game and use the idea on your own board.

Have a good game!
