A brave choice by Habu. This position should be the reason to play
the Kakugawari with tempo loss in the first place. In the normal
Kakugawari, the white pawn is on 8e instead of 8d, so in this
reclining silver position white has the extra option of N8e. However,
this position has appeared in professional games 11 times and black
won ten times, so statistically it can hardly be called an advantage
to have the N8e attack. On the other hand, Habu was the only player
to win from this position with the white pieces. This game seems to
show that it is not as bad for white as the results seem to indicate.

74.P9d-9e? 03:23:00 03:14:00
Moriuchi was far from happy with his position here. White has attacked
first and the difference between the two king positions is considerable.
On the other hand, the white attack only consists of two pieces, one
of which (the bishop on 6h) can be taken any time. Furthermore, the
bishop on 6d works in defense. The position is still very difficult,
with maybe a slight edge for white. However, 74.P9e, as natural as it
seems, is an overplay. Better was 74.G3d and after 75.P*4c Sx4c Nx4c+
Rx4c P*5d R4i+ Px5c+ K2b white is clearly better.
75.+B6dx9a 03:29:00 03:14:00
76.P9ex9f 03:29:00 03:14:00
With a gold in hand, there is a mate in one. Appealing, but not so easy
to realize.
77.P8g-8f 03:38:00 03:14:00
78.G4c-3d 03:38:00 03:24:00
79.L*4f! 03:48:00 03:24:00
This lance sacrifice is important, as it defends both against the promotion
of the rook and against Gx3e Gx3e +Bx3e. This slows down the white attack
considerably, giving the black king time to try and escape up the board.
80.P*4e 03:48:00 03:35:00
81.K9h-8g 03:48:00 03:35:00
82.P4ex4f? 03:48:00 03:44:00
Habu was in two minds here: play the natural Px4f, using the lance on the
9th file to stop the king or play 82.Gx3e 83.Gx3e 84.+Bx4f 85.+Bx4f 86.Px4f.
In the end, he went for the natural move. A mistake and not really Habu's
"magic" style. If he would have played 82.Gx3e, then after 86.Px4f black
can try 87.B*5a, but after R5b Bx3c+ Nx3c P2d Px2d P*3d B*8h white has the
advantage. Also, 87.P*4c Sx4c N4e S3c-4d seems good for white. There are
many difficult variations here, so it is impossible to make a definite
conclusion, but Habu agreed after the game that after 82.Px4f he was in
trouble and that he should have played 82.Gx3e instead.
83.P*4c 03:48:00 03:44:00
84.R4b-4a?! 03:48:00 03:44:00
Here 84.R5b is better. Black seems to have the advantage then as well,
but the white position would have been stronger and it would have been
easier for black to make a mistake.
85.+B9a-6d 03:48:00 03:44:00
86.P4f-4g+ 03:48:00 03:44:00
87.P2e-2d! 03:53:00 03:44:00
The decisive move. 88.Gx2d is answered by 89.N2e and 88.Px2d by 89.P*2c,
so Habu has no choice.
88.S3cx2d 03:53:00 03:46:00
89.P*3c 03:56:00 03:46:00
The natural attack, but Hashimoto (5-dan) pointed out that 89.Nx2c+ Gx2c
+Bx5c is also good for black.
90.G3dx3c 03:56:00 03:47:00
Or 90.Nx3c Rx6h Sx6h= B*5b and black wins.

117.S7h-8g 03:59:00 03:59:00
Resigns 03:59:00 03:59:00
After 118.+Bx7g, the bishop no longer defends 1c, so 119.G*2a leads to
mate. Also, black has Sx9f or Rx6h next, which completely stops the white
attack. With this win, Moriuchi takes the Kio title from Habu. From 1990,
Habu won 12 consecutive Kio titles, but the last four years, the title
has changed hands every year. For Moriuchi, it is the first time he
takes a title in a one-day title match, the other five titles he won
have all been in two-day title matches. A great way to celebrate the
birth of his first child a week earlier.
