The tactic like ▲N*24 which I
wrote in the previous article can be also seen in
joseki.
Diag.1 is one of the Yagura Joseki called Katou Style (9-Dan Katou plays this strategy frequently.) It is the
sente's variation
in Yagura Silver-37 Strategy, characterized by pushing the edge pawn and ▲P-26 before advancing the silver
to 46. And, the knight jumps into 25 through 17.

Here,
gote plays △N-33 before the attack from ▲S-46 and ▲P-35. In general, the equal exchange between an attacking piece and a defending piece is good for an attacking side. But, in this case,
gote has a threat with the knight in the next.
After △N-33, it proceeds with ▲Nx+ △G32-33x (△Sx and △G43-33x are also available) ▲S-46 (Diag.2). △G32-33x means preparation for the attack from above. It doesn't look like a good shape, though.

In Diag.2, △N*86 is the
move that
gote had been aiming at since △N-33.
After ▲Px △Px (Diag.3), it looks like there is no piece to drop
on 87. But, in the next, it's possible to gain a silver with △Bx46 and drop it
on 87. Breaking the point in front of the king is more valuable than bishop-silver exchange. Then, promoting the rook and taking the material back can be expected in the future.

| Diag.3 |
To remove the threat of △Bx46,
sente needs to select ▲P-55 or ▲N*79 or ▲Sx.
In reply to ▲P-55, the attack with △N-85 ▲Sx86 △Nx97+ ▲Kx △P*85 (Diag.4) is effective. The silver on 86 cannot move due to the bishop's line. If ▲Lx is played instead of ▲Kx,
gote will take the silver with △Bx86 ▲Bx △Rx.
Gote is better at Diag.4 because
sente doesn't have a rapid attack to
gote's castle yet. As you know, in the endgame, the speed to break the opponent's castle and capture the king is the most important thing.

| Diag.4 |
▲N*79 is the same as ▲P-55.
Gote will get better with the attack from △N-85.
Therefore, ▲Sx is a common move in Diag.3. After that, it proceeds with △Bx ▲Bx △Rx ▲P*87 △R-82 ▲P-35 (Diag.5). Many pro players regard Diag.5 as slightly better for
gote. Thus, instead of ▲S-46 in Diag.2, ▲N*65 was played in recent pro game.

In this way, even if the position is still in the middle game, the tactic like △N*86 would go well depending on the situation.
Dear Akira, once again thanks for an excellent blog.
返信削除The best wishes for a happy new year! It was interesting to talk with you in Shizuoka, hopefully we can continiue the discussion one day.
I have a question:
After N*86, what happens is Sente continiues with: G79? Its very hard ( for me) to understand if Gote has a strong attack, or the knight on 86 is "stuck"
Greetings Peter Heine
Hi, Nielsen
削除I wish you a happy new year! I was glad to talk with you and know more about chess players in Shizuoka.
As you say, after G79, there is no effective attack immediately. But, if gote gets a pawn in hand, it will be possible to attack with P96, Px, P*98. So, sente cannot attack with P35 next. I think, against G79, it's good to improve the shape of Yagura with G32 and aim for P45, Sx, B19+.
