Lecture 7: Ishida Style

1. Masuda and Ishida Style

So-called 'Ishida Style' can be considered two main valiations. One is 'Classic Ishida Style' which is without Bishop exchange, the other is rough game which is with that. In this lecture, I name the rough game 'Quick Ishida' and distinguish it from Classic Ishida Style. Of course 'Masuda Style Ishida' is included in Quick Ishida.

Now, speaking of Quick Ishida, I remember Meijin title match in 1971. This was a very big event for Ishida Style as well as professional shogi world. To speak of extremes, this was a watershed for Quick Ishida.

Kouzou Masuda, who stood in the limelight in Meijin title match for the first time in 3 years, challenged Yasuharu Oyama Meijin with his favorite Masuda Style Ishda. Shogi fans cheered with keen interest Masuda Style Ishida which Masuda fully showed his talent on a board. He played Quick Masuda - which was made fun of like "kindergarten-style surprise attack" some time ago - making unigue improvements in Meijin title match. There is few such a wonderful episode.

Masuda was 53 years old, and Oyama 48 at that time. This was a last Meijin title match for them. So let's take a look at the title match from Masuda's point of view.

1st game. He (white) played Back Bishop against Oyama's Fourth File Rook, but didn't work good (he lost).

2nd game. He (black) played Quick Ishida. He showed ▲B*9f (Diag. 1) which is a standard available even now (he won).

3rd game. He (white) played Quick Ishida. He showed △S-3e, which is so-called 'heaven-sent brilliant move' (he won).

4th game. He (black) played Quick Ishida. After a fierce battle, he lost the game by a hair.

5th game. He (white) won the game against Oyama's Opposing Rook. 3 wins-2 lose, so he needed 1 win to reinstate in Meijin.

6th game. He (black) played Quick Ishida. He showed brilliant Bishop Drop, ▲B*6g (Diag. 2) , but eventually he lost.

’Masuda's bishop’ appeared continuously in Meijin title match in 1971. ▲B*9f is the most famous dropping bishop. The aim is ▲B-8e ~ ▲R-8f next. If △B*9d from Diag. 1, Black leads the position by ▲Nx8e △Bx8e ▲R-8f.
6th game. After Diag. 2, Masuda got a pawn by ▲P-5e △Px5e ▲Bx3d. Oyama made a counterattack at that moment.

Then, fatal 7th game has come. He got black by toss, and he played Quick Ishida without question. Oyama built up his line and suppressed Masuda's line by advancing gold and silver flexibly (Diag. 3) .

Although Masuda had tough time, he caught up with and then there became a confused game. Then, fatal 91th move has come (Diag. 4) . If Masuda had moved his Gold to 5e (▲G-5e), destiny of the 2 big players and that of Quick Ishida might have been changed.

7th game. After Diag. 3, the game proceeded to △G-4b ▲S-5g △P-8f ▲Px8f △P-7f ▲S-6f △S-4c. Oyama prevent Masuda from attacking, then he had a strategical victory.
It would be an unclear position if Masuda were to play ▲G-5e. In actual game, it proceeded to ▲Lx1d △P-5d ▲P*4e △+Bx4e ▲S*3f △+B-4d ▲P*4e △+B-6b. Oyama's camp became so solid.

In fact, he took silver by lance (▲Lx1d), so then △P-5d (by Oyama) became a brilliant move which not only made his promoted bishop move easier but also prevented opponent gold from advancing. Oyama won the game, so he defended his title.

Although Masuda played Quick Ishida 5 times out of 7 and reached one step away from Meijin title... His sorrow was immense. This was the last Meijin title match for Masuda, while the last defense of Meijin title for Oyama.

The flows of the title match is just above, but if we take a look at it from the history of Ishida Style strategie's point of view, we can see a different meaning.

That means, Masuda suffered how to start a fight. Oyama tried to block Masuda's first fight by clever piece formation. You can play various fight by Ishida Style if you have just a pawn, but Oyama barely allowed you to get one. Therefore Masuda dropped, or had no other choice but to drop his bishop in his own camp in order to get one all the way.

In 2nd game, He played ▲B*9f in order to get a pawn on 8e.

3rd game was white's Quick Ishida, so it is considered as an exception.

In 4th game, He played ▲B*5e (Diag. 5) .

In 6th game, ▲B*6g in Diag. 2 finally got a pawn on 3d.

However, few people can copy such bishop drops in his own camp.

Then, in the final game, Masuda eventually played ▲P-7d in order to exchange a pawn (Diag. 6) . However, this was just a thing which Oyama was waiting. Oyama played △G-7b. He speeded up the progress of his gold, while Masuda went into strategical loss. After the game, △G-7b even became a standard against ▲P-7d if white's right silver was on 6b.

After Diag. 5, it proceeded to △P-4d ▲Bx6d △S-6c ▲B-5e △R-8d ▲B-6f △B*6d ▲P-7d △R-8c ▲R-9f. Masuda made all kinds of efforts to get a pawn in hand. He must be finding the key of the strategy.
Though Masuda finally played ▲P-7d, this was just the move that Oyama was waiting. After that, it proceeded to △G-7b ▲Px7c+ △Gx7c ▲R-7f △K-4b ▲G-7h △P-4d ▲S-6h △G-5b. Advancing pieces by Oyama has just started.

In conclusion, considering the content of the Meijin title match, Quick Ishida obviously had tough fights, and Masuda just covered it by his talent.

A comment by 8-dan Suzuki is very impressive. "Although this is just an image which I have when I replayed the game, master Masuda didn't seem to rely on Quick Ishida. He seemed to take a risk to play Quick Ishida. I think it is a big reason that he was expected to play Quick Ishida by fans. There were many surprise move including the game move from the opening in order to avoid being short of moves. I think he must have been overwhelmed."

Oyama's strategy which prevent Quick Ishida from disposing of pieces became a basis against Quick Ishida, so Quick Ishida couldn't be promoted to major opening. In a word about disadvantage, "Black's Quick Ishida tend to be short of moves, while White's Quick Ishida is no chance ever due to one move late." In particular, current top professional players also say with certainty that white's Quick Ishida is not working.

Black's Quick Ishida had one more serious problem. If white were to compromise and then black were to built Classic Ishida Style, Black would have a natural enemy. That is "Climbing Gold" which is a tactics against Floating Rook exclusively. What is worse, both Oyama who had Meijin title 18 seasons and Nakahara 15 seasons were good at demolishing Ishida Style. Due to the fact that Meijin at the time was good at demolishing Ishida Style, the statics couldn't be hot among professional players even if it was among amateurs.

Because of such situations, white plays △S-6b after ▲P-7f (first move) △P-3d ▲P-6f at ease. From that point on, Quick Ishida became "the forgotten tactics" or "the tactics you can't play even if you want to". Though Toshiaki Kubo and Daisuke Suzuki played Ishida Style sometimes and got a certain good record, they played it with a plenty of tricks by their talent as 'big three', so their games couldn't be introduced from standard's point of view. Even Kubo or Suzuki didn't play Ishida Style as a starting tactics, but a reserve tactics using depending on their opponent.

However, what I have to add a story in order to avoid misunderstanding is that it's not mean that the people of the past thought "Quick Ishida is completly extinct.". People also thought that the tactics invented by Masuda was still profound because he invented a great number of new moves and new tactics as well. "I bet there will still remain more vein which we haven't digged up in Masuda's shogi." (Yasumitsu Satou), "There is a possibility that there are new discoveries in his game records which we haven't seen yet." (Yoshiharu Habu) Active top players don't hide their adoration for Masuda.

2. Don't be afraid of Climbing Gold

As I discussed in section 1, Ishida Style had 2 difficult problems, that were short of moves and Climbing Gold. Reviewing of Ishida Style was started from Classic Ishida Style first. Kubo Created an oppotunity.

Moves from Diag. 7
 ▲R-7h △P-5d
▲G-6g △S-5c
▲G-7f (Diag. 8)

The memorable 'signal of revival' of Classic Ishida Style started in 2000. The key is not to play ▲N-7g but wait for △G-8c. In this actual game, each player were looking for the right time to shift formation.
Black exchanged pieces by ▲R-7h ~ ▲G-7f quickly. After Diag. 8, it proceeded to △G-4b ▲S-6h △P-7d ▲S-6g △Px7e ▲Gx7e △P*7d ▲G-7f △G-8d ▲P-6e. Black's incomplete Mino was even stronger than white's castle. He took advantage of it.

Kubo neither moved his left silver to 6h (7h), nor his left knight to 7g. He was waiting instead. And then, when white advanced his right Gold as △G-8c, Kubo moved back his rook as ▲R-7h and exchanged the position of his gold for rook as ▲G-6g ~ ▲G-7f. This was a good idea by which everyone was impressed.

Speaking of the number of possible moves adjacent to own piece, gold has 6 while rook 4. Therefore, rook has disadvantage against gold regarding close fighting. This is a logical proof about the advantage of Climbing Gold against Ishida Style.

So he thought, is the tactics effective that exchanging offensive piece (rook) for defensive one (gold) and match-up his gold to the opponent's gold? This is a brilliant idea. If left gold were to get away from his king, Mino castle is stronger than the opponent castle!

In addition, Kubo, an artist of disposing of pieces, showed beautiful disposing of pieces in this game. Now, white has just played △B*5g...

Moves from Diag. 9
 ▲R-5h △B-7i+ ▲B*4f △+Bx4f
▲Px4f △G-7d ▲P-4e △Sx4e
▲P-5e △B*7i ▲S-5f △B-3e+
▲Sx4e △+Bx4e ▲S*6c △G-7c
▲B*7a △R-9b ▲Sx5d= △Sx5d
▲Px5d △P*5b ▲P*4d (Diag. 10)

The position is a dozen moves after Diag. 8. After Diag. 10, Kubo started beautiful disposing of pieces.
If △Px4d, then ▲P-5c+. If △+Bx4d, then ▲Bx4d+ △Px4d ▲S*5c. Both black attacks would go well. In actual game, it proceeded to △P*6b ▲S*5c △Px5c ▲Px5c+ △+Bx4d ▲+Px4b △Kx4b ▲G-5e. Black amazingly disposed of his all attacking generals.

There are many moves, but you may understand black was attacking bullying white's climbing gold. And then after Diag. 10 , you can imagine the bullying white's promoted bishop by ▲G-5e, can't you? After that, Kubo played beautiful moves and eventually won.

Actually, I had a official game next to Kubo at that time, and I admired the brilliant moves for a while. You might think "You are not proper despite during your game!", but the opponent had a same feeling as I, and admired it, too. "Can you believe that such a beautiful disposing of pieces appears in professional game?" Thus, that moves was so beautiful, and rarely seen brilliant.

With this game as a start, people have been reviewing the fight between Ishida Style and Climbing Gold. People investigated ▲S-6g formation too, and then people created many kind of counter-plans. For example, 8-dan Fukaura did.

Moves from Diag. 11
 ▲S-5f △G-8d ▲S-4e △G-3c
▲P-6e △B-3a ▲R-3f △P-3e
▲Rx3e △P-9e ▲Px9e △Lx9e
▲B-8h △P*9h ▲N-1g ! (Diag. 12)

Fukaura played ▲N-7g with ▲G-7h formation, then he was waiting for the right time of ▲P-6e. No sooner did he see △G-8c than he started a fight. 2006
Fukaura showed a fierce attack as if right knight in Mino castle was a valuable attacking piece. After Diag. 12, it proceeded to △P-2d ▲Nx8e! △Gx8e ▲Bx3c+! △Nx3c ▲S-3d. He rushed to head of the opponent's castle, and eventually crushed it.

In spite of ▲G-7h, black's castle is strong as well as white's because white's castle is weak. Fukaura took advantage of that, that means he advanced his silver to the head of opponent's king, and eventually won a complete victory. Fujii said "He plays Ishida Style better than I." We might have to say that is 'terrible Fukaura Style Ishida'.

And a quick digression, There is a professional shogi player (Tanigawa) who plays ▲P-6f after ▲P-7f (first move) △P-3d, and plans 2 openings as Double Ranging Rook and Yagura, but Fukaura goes more straight his own way. If his opponent is a static rook player, he selects Yagura after ▲P-7f (first move) △P-8d, or he does Quick Ishida after ▲P-7f (first move) △P-3d. Now, the border between static rook players and ranging rook players almost passes away.

There is also an advanced game record as follows.

Moves from Diag. 13
 ▲R-7h △P-8f ▲Px8f △P*8g
▲B-7g △Gx7e ▲P-6e △Bx7g+
▲Rx7g △P*7f ▲Sx7f △G-6f
▲S-7e △Gx7g ▲Nx7g △B*5e
▲P*7h △R*6i ▲G*4e (Diag. 14)

Nakao didn't play ▲N-7g but ▲S-6g, then he was waiting. He invited white's Climbing Gold and then made a counterattack by ▲R-7h.
After Diag. 14, it proceeded to △B-2b ▲G5-5i △Rx9i+ ▲Px6d △S-5b ▲S-7d △P-8h+ ▲P-6c+ △+Px7h ▲N-6e. Nakao disposed of his all attacking pieces.

Although the moves is more difficult than the previous one, I would like you not to be concerned about the details of variations, but to think what black want to do. So, you will see the meaning of the moves. Black move back his rook to 7h and make opponent's pieces extend upward too, then he plays ▲P-6e in order to dispose of his bishop. This is a trick of Ishida Style. After Diag. 14 , black plays as if he creates attacking formation around opponent's castle.

This game goes on to Diag. 15 later. Black escapes from white's attack by promoted pawn in order to delays their attack, and so he takes hold of turn to play. After Diag. 15 , △P*7c ▲+Px5b △Gx5b ▲S*5c △Sx5c ▲Nx5c+ △B-3a ▲S-6c+ △Gx6c ▲+Nx4c (Diag. 16) and eventually black won by taking advantage of his strong and compact castle.

Since Nakao's king wouldn't be threatened mate if white were to play △Px1f, He can attack boldly. This is a technique of endgame by the player who is familiar with Mino castle.
If △Kx4c, then ▲Bx3a+ is threat mate, so black will win. In actual game, it proceeded to △K-2b ▲Bx3a+ △Kx3a ▲P*6b △+P-5h (if △Rx6b instead, then ▲B*4d) ▲S*3b △K-2b ▲B*4d. Black got won position.

3. Resurrecting Quick Ishida

Following Kubo's counter-plan against Climbing Gold, here comes a great new move. It has been 30 years since the last Meijin title match by Oyama and Masuda was held. A little inspiration digged up 'a hidden vein'. It was in May, 2004. In Ginga-sen, Daisuke Suzuki VS Kiyozumi Kiriyama, the commentator was 9-dan Oouchi who is a master of Suzuki, and I also watched the gamelive on a monitor. The game started ▲P-7f △P-3d ▲P-7e △P-8d ▲R-7h △P-8e, and then Suzuki played ▲P-7d △Px7d ▲Rx7d (Diag. 17) . Oouchi was stunned at the moment. He asked "(After △Bx8h+ ▲Sx8h) How about △B*6e ?", and figured out in a moment. "Oh, there is an opposing bishop (▲B*5f). I see. This must be a new move by Daisuke."

If black plays ▲P-7d after △S-6b, then white plays △G-7b that is bad for black. Suzuki played ▲P-7d before △S-6b though his king was even on 5i (a sitting king). Spirit of an age who didn't hesitate to become a battle royal discovered the new move.

He figured out immediately what his apprentice was thinking. This was the first time a keyword '▲B*5f' appeared in official game. Kiriyama might sensed danger, so after Diag. 17 he played △P-7c ▲R-7e △P-8f ▲Px8f △Rx8f ▲G-7h. The position is a free-style (not a standard), which Suzuki wanted to be (I will discuss the variations later).

This was just the time Quick Ishida opened new avenues. The reason Quick Ishida tends to be less of moves is the difficulty of getting a pawn in hand though Ishida Style formation might be created. If Ishida Style (black) can get a pawn in hand in 7th file, black doesn't need to be afraid of draw by repetition of moves, and attack freely.

Thus, Quick Ishida was resurrected. After ▲P-7f (first move) △P-3d ▲P-7e △P-8d ▲R-7h, if white plays △P-8e, black plays ▲P-7d △Px7d ▲Rx7d. It keeps away from being less of moves. The counter-plan by Classic Ishida Style against Climbing Gold is also invented (as I discussed earlier). That's all to play Ishida Style.

In early summer, 2006, Suzuki became a challenger of Kisei-sen title match with Ishida Style. He played all games by Gokigen Central Rook or Ishida Style except 1 game, and eventually got the right to challenge. And then in Kisei-sen title match, he played Quick Ishida when he had black. Kisei Yasumitsu Satou accepted the challenge proudly.

In 1st game, after Diag. 17 , △Bx8h+ ▲Sx8h △B*6e ▲B*5f, then △B-5d (new move at that time). In 3rd game, after Diag. 17 , △Bx8h+ ▲Sx8h △B*6e ▲B*5f, then △Bx7d ▲Bx7d △G-7b ▲B*5e △P*7c ▲B-5f △R*1b (Diag. 18) .

After Diag. 18, both players built their own camp steadily. It was even 62th move that the rook in the own camp moved. The position is just like a street fight. "Come on with your real power!"

Both games were strong-arm fights, in other words, not fights in a hall but street fights. Suzuki played clever moves and had the initiative, but gave in by the power of Satou from middle game. Unfortunately he missed the title, but Quick Ishida itself worked well.

Next, let me show you the Interview just Suzuki.

4. Pleasure of Ishida Style

---
What triggered your finding ▲P-7d?

Suzuki
 It was in a study group held a few month before the actual game. I was not interested in Quick Ishida at that time, but the theme in the study group was free-style ranging rook, so I played many kind of variations of Quick Ishida. Then I played ▲P-7d, △Px7d, ▲Rx7d. Apparently it didn't work well due to △B*6e, but then I dropped my bishop on 5f as a trial... It started. I dropped the bishop just unintentionally and casually.

---
It's like "Hyoutan kara koma". (! this is a Japanese proverb. It means that something very unexpected, something said as a joke actually happening.)

Suzuki
 Yes. I was interested in the opening after that, so I was studying it after I came back home. Then I played it in the game against Kiriyama.

---
What is the aim of ▲P-7d, and what kind of positions are ideal for the tactics?

Suzuki
 The aim is to get a pawn in hand, and to make black's rook move freely. In details, if △P*7c after ▲P-7d △Px7d ▲Rx7d, black plays ▲R-7e △P-8f ▲Px8f △Rx8f ▲G-7h (Diag. 19) .

If white were to play △Rx8h+ ▲Sx8h △B*8f after that, then black would play ▲R-7g (black lead the position). So, after Diag. 19 , it would be △S-6b ▲P*8g △R-8b and then ▲K-4h △K-4b ▲K-3h △K-3b ▲R-7f △S-4b. After that, black moves around like ▲R-8f △P*8e ▲R-3f (Diag. 20) . You feel good moving your rook freely like that, don't you? (lol)

If △Rx8h+ ▲Sx8h △B*8f after Diag. 19, then ▲R-7g △G-7b ▲K-5h △Bx7g+ ▲Sx7g that is even. If it becomes a slow game, black is satisfied with building a credible Mino castle.
The black's position is just like Masda Style Ishida with a pawn in hand. In addition, black blocks white's Anaguma whereas he builds Mino castle, so black is feeling good.

After Diag. 20 , black leads the position by building Ishida Style ordinarily. Black can build Mino castle, while white cannot build strong one. I have complete confidence in Mino castle in my tactics. It is ideal shape that I build Ishida Style and Mino Castle while opponent cannot build Anaguma.

---
I would like to confirm a fundamental issue. What kind of variations would be after △B*6e ▲B*5f (Diag. 21) ?

Suzuki
 For example, if white were to play △Bx5f ▲Px5f △P*7c, black would played ▲R-7h. After that, if white were to play △B*5g, then there would be an example like ▲P*7d △Px7d ▲B*5e △S-2b ▲Bx8b+ △Sx8b ▲Rx7d △S-3c ▲G-4h △P*7c ▲R-7h △B-8d+ ▲K-4i (Diag. 22) . It is like a position of free-style ranging rook, in which black can play as he wants thanks to a pawn in hand.

Black can play ▲P-7d thanks to the move (▲B*5f). After Diag. 21, △Bx7d, △Bx5f, and △B-5d are the typical variations.
After long period of building formations, black started a fight by ▲S-7g ~ ▲R-8h ~ ▲P-8f.

---
What is the variation you are concerned about?

Suzuki
 After Diag. 21 , It is difficult that △Bx7d ▲Bx7d △G-6b (Diag. 23) . After Diag. 23 , there would be an example like ▲B*5e △P-4d ▲B-5f △S-3b ▲P*7b △Gx7b ▲Bx4d △N-3c ▲P-3f (Diag. 24) .

If △S-6b instead of △G-6b, then ▲B*5e △P*7c ▲B-6e that is good for black. The formation of 2 floating bishops is like Demon Killer (Oni Goroshi in Japanese), which is very interesting.
Black doesn't promote his bishop, but aim to attack head of opponent's left knight, that attack is more effective. Continuity of attack should be emphasized in the position.

---
There are many kind of violent variations.

Suzuki
 Right. There are tough fight for black in order to build ideal shape. In actual games, there are few being such variations, but being slow game usually because white compromise on building Ishida Style for black.

---
What is the key about against Climbing Gold?

Suzuki
 I prefer to ▲G-6g formation. It is the same as Kubo. Once you keep away from opponent's attack and build formation steadily, you will take hold of the initiative. One of the most important thing is not to jump left knight to 7g too early. Notice that "you should play ▲R-7h against △G-8c".

The reason of building Floating Rook is to use left knight by ▲N-7g. However, jumping knight too early makes your rook and bishop being less of moves, so the risk that they are targeted would increase. The major pieces are strong regarding attack, while weak regarding defence. Therefore you have to take care of the timing of jumping left knight to 7g. Knight can move 2 squares by one move, so you don't have to jump it in a hurry. Take care of opponent's attacking formation, especially the move of right gold, and you won't be afraid of Climbing Gold.

Though ▲S-6g formation can use similar strategy, I recommend you to use ▲G-6g formation because of the stability that you can keep away from opponent's quick attack for sure. Notice that Climbing Gold has not gone extinct yet because static rook players are studying the opening and they might find out good new moves.

---
I would like to ask about slow game. What do you think of Silver Crown?

Suzuki
 It is the tactics which players tend to review. I have been beaten by the tactics in a big game. Silver Clown with △S-6c formation is solid in their camp totally, so it is tough to beat. I castle my king in Mino castle as usual. You can jump left knight to 7g because white moves right gold to 5b that means he doesn't choose Climbing Gold. On the other hand, it is difficult how to activate bishop. Let's take a look at an actual game.

Moves from Diag. 25
           △R-9b ▲Nx8e △R-8b
▲P-8f △R-8d ▲B-8h △P-5d
▲B-7g △P-5e ▲S-6g △G-5c
▲B-5i △G-5d (Diag. 26)

Silver Crown is one of the good formations against Classic Ishida Style. In addition, Silver on 6c defends against black's attack from 7th file. This position has appeared 5 times in the past. All players have played △R-9b after that in all cases.
In actual game, it proceeded to ▲R-7i △P-4d ▲P-3f △P-6e ▲Px6e △P-4e ▲Px4e △Gx4e ▲R-7f △S-5d. White built a good formation.

△R-9b is a scare tactics. If black were to play ▲B-7i, it would be △R-7b ▲B-9g △R-9b which would lead draw by repetition moves. White would be satisfied by draw by repetition moves (because he would get black in new game). Therefore black plays ▲N-8e instead, but white builds solid formation in central file.

In this case, I think black had better not play ▲B-9g, but ▲P-4f ~ ▲P-3f in first. If so, black's bishop can shift to 7g ~ 5i ~ 2f. It is the key how to activate bishop after building Classic Ishida Style.

---
I see. How about Anaguma?

Suzuki
 Anaguma is a tough enemy. It would be ideal that Ishida Style castle in Four Generals Mino steadily and eventually win, but it is tough in actual game due to the solid formation of Anaguma. So, you had better prevent opponent from castling in it. In detail, you had better play ▲P-6e in order to dispose of bishop at just the timing when opponent tries to castle in it. Let me introduce two actual games.

Diag. 27 is Kouji Tanigawa VS Hiroyuki Miura. Now white tries to castle in Anaguma, then black starts a fight aggressively.

Moves from Diag. 27
 ▲P-1f △K-1a ▲G-7h △S-2b
▲P-6e △B-2d ▲S-6h △P-5d
▲P-7d (Diag. 28)

Whenever static player tries to castle in Anaguma, ranging rook player has a chance to start a fight. After Diag. 27, there is an actual game that black started a fight by ▲B-7g △K-1a ▲P-6e and eventually won.
Tanigawa started a fight getting a pawn in hand and tried to put white off balance. After the position, he continued attacking by beautiful moves.

Next game is Kouichi Fukaura VS Manabu Senzaki. Black starts a fight by P-6e as well.

Moves from Diag. 29
 ▲B-7g △K-1a ▲P-6e △Bx7g+
▲Nx7g △B*8h ▲P-7d △S-2b
▲B*5e (Diag. 30)

There is a proverb, "Against Anaguma, aim at bishop exchange". How do you exchange bishop in the position?
After Diag. 30, it proceeded to △Bx9i+ ▲Px7c+ △Sx7c ▲Bx7c+ △Nx7c ▲Rx7c+ △R-8a ▲S*8b. Fukaura was attacking powerfully, and eventually won.

It's easy to understand, isn't it? From Diag. 30 , attack as much as you can. (lol)

---
Fujii said "Natural ranging rook players tend to choice a move which is not bad, while static rook players tend to choice an aggressive move in order to take hold of initiative.". These moves are just the ones (! Tanigawa and Fukaura are basically static rook players).

Suzuki
 Absolutely. The key is that black put off moving gold, silver and right knight, while he castle his king in Mino castle quickly. This is the strategy which is simple and easy to understand. If opponent were to play quick attack, all you have to do is move left gold to 5h.

The move which Ishida Style can put off moving is ▲N-7g, right?

Suzuki
 Right. Actually, Quick Ishida can use the same idea. I think we have to review ordinary Quick Ishida which is without ▲P-7d.

What do you mean?

Suzuki
 Ordinary Quick Ishida still has possibility to be better strategy. Take a look at Diag. 31 , for example. Black played ▲S-7g instead of ▲N-7g, and has just played ▲P-8f. If white were to play △Px8f ▲Rx8f △P*8e, black would play ▲R-8h and then try to make a counterattack by ▲S-7f. black is concerned about the moves like △P-3e ~ △B*5e (! The aim is △P-3f), so play ▲P-5f at the right moment in order to prevent △B*5e and you will fight enough.

Suzuki says that obsession with activation of left knight leads to the short of tactics. He has tried ▲P-8f as shown in this diagram, and then it proceeded to △B*5d ▲R-4f △P-9d ▲Px8e △Rx8e ▲R-8f.

In Meijin title match between Oyama and Masuda, Masuda played ▲N-7g in almost all games, which I think narrowed the range of choice of his tactics.

In addition, take a look at Diag. 32 . This is Toshiaki Kubo VS Yoshiharu Habu. The same position as this appears in Meijin title match I discussed above. The difference is only 2 moves of ▲P-9f △P-9d. In Meijin title match, the game proceeded to ▲R-7f △Bx8h+ ▲S-3b, while the game Kubo-habu proceeded to ▲P-6f △K-3b ▲R-7f which leads to Classic Ishida Style. If white were to play △P-8f after ▲P-6f, it would be ▲Px8f △Rx8f ▲P-6e △K-3b ▲Px6d △Sx6d ▲Bx2b+ △Sx2b ▲R-8h △P*8g ▲R-6h (Diag. 33) in which Kubo thought he lead the position. Thus Quick Ishida has a component that is an advanced tactics of free-style ranging rook such as Gokigen Central Rook. I think there is more in it.

Although the similar position of the diagram appeared in Meijin title match between Masuda and Oyama, the difference is the exchange of edge pawn, which is an innovation by Kubo. After the diagram, He played ▲P-6f! He considered △P-8f as no fear.
If white were to play △P-8f after ▲P-6f from Diag. 32, white's camp would be out of control like Diag. 33 because his pieces are discrete. In actual game, black succeeded in building Classic Ishida Style, but note that the position is even. There is a high possibility that the opening of Ishida Style has even a lot of new moves.

Many people have been thinking you are a typical fourth file rook player. Why did you start using Quick Ishida so constantly?

Suzuki
 If I use fourth file rook, opponents often use static rook with Anaguma. It's not fun for me that it proceeds to similar formation until halfway many times. In addition, I don't use Fujii System (! that means it makes him narrow the range of choice of tactics), so it is relatively easy for opponent to see ahead my move. Therefore I tend to lose by Anaguma in close game.

Now, when I have white I rely on central rook completely, so I use only central rook. I never take disadvantage in opening and middlegame when I use central rook.

A problem is when I have black. I would use fourth file rook if I knew opponent never use Anaguma. Currently I'm fully occupied by studying central rook and third file rook.

Anyway, Quick Ishida can fight enough by using both P-7d and ordinary Quick Ishida. When building Classic Ishida Style, you don't be afraid of either Climbing Gold or Anaguma. Ishida Style is a pleasant opening, so let's give it a try.
