The R8e-Yokofudori and the Gokigen-Nakabisha are followed by the 
Kakugawari opening. As is often the case in matches between Habu 
and Sato, there is a lot of variety in the opening strategies. Good 
news for shogi fans who like to see different types of shogi.

Diagram 1

So far, this position has appeared in a large number of professional 
games. The most popular line is 43.P1e Px1e P7e Px7e P2d Px2d Rx2d 
P*2c R2i, where the white weakness on 7d becomes the main theme. 
The results for black in this position are good, but there is no 
definite conclusion about whether black objectively has the better 
position. Sato has prepared a new move in an older variation.

44.P2cx2d    01:54:00  02:35:00
45.R2hx2d    01:56:00  02:35:00

47.R2d-2h    01:58:00  02:37:00
48.P6d-6e    01:58:00  03:02:00
49.P6fx6e    02:09:00  03:02:00
50.P7d-7e    02:09:00  03:04:00
51.B*6d!?    03:18:00  03:04:00

Diagram 2

The move Sato prepared. It is almost ten years ago since the position 
after 50.P7e appeared in a professional game. In the 4th game of the 
1993 Kisei match between Goda and Tanigawa, Goda played 51.S6f P9e 
Px9e P*9g Lx9g P8f and white won. 

52.G5b-6c    03:18:00  04:45:00

It is not a surprise that Habu took a long time for his reply to 
51.B6d, but 1 hour and 41 minutes is unusually long for him. This 
was the sealed move, and even though he asked the keeper of the game 
record (Yamamoto, 4-dan) to prepare for the sealing of the move at 
18:10, it actually took him another 21 minutes to seal the move. 
The problem was that he had a hard time dismissing the alternative 
52.B*8d, which he considered the more natural move. However, after 
53.S6f P*6c Bx7e Bx7e Sx7e Nx6e S6f B*6d B*5i, it seems white has 
nothing else but P*7g Nx7g Nx7g+ Sx7g Sx3e P*6e B7c which doesn't 
seem to work well for white. Habu finally decided that 52.G6c was 
the better move.

53.B6dx7e    03:23:00  04:45:00
54.S5dx6e!?  03:23:00  05:19:00

Diagram 3

A surprise. This is not the natural move. Of course, if black plays 
55.Sx6e Nx6e, white has developed the knight and exchanged a silver, 
which would be very good. However, the silver on 6e blocks the knight 
on 6e, so if the silver exchange is not played, it can be hard for 
white to develop his pieces. Habu had looked at 54.Nx6e, but he 
didn't like 55.P*2b. Then 56.Kx2b B6f gives black a good bishop 
line to the white king and 56.Gx2b puts the gold on a bad square.

55.S5fx4e    06:56:00  05:19:00

Not record-breaking, but thinking for 3 hours and 33 minutes is 
exceptional. In title matches, only Yonenaga once thought longer 
(217 minutes) about his move in the 3rd game of the 34th Osho 
match (1985) against Nakahara. The record for a non-title match 
game belongs to Kanezawa, who once thought 286 minutes in a game 
for the Oi title against Yashiki in 2001. In light of the previous 
comment, moving the silver away from the exchange, seems to be the 
most natural move. 

56.S4dx4e    06:56:00  05:48:00
57.N3gx4e    06:56:00  05:48:00
58.S*4d      06:56:00  06:20:00
59.P*2d      07:09:00  06:20:00
60.P2cx2d    07:09:00  06:35:00
61.P*6d?     07:30:00  06:35:00

Diagram 4

The only real mistake in this game, but unfortunately for Sato a 
game-ending one. He should have played 61.P*2c here. For example, 
62.Gx2c P*2e Px2e S*6d G7d Sx7c+ Gx7c N*3f Sx4e Bx5c+ S*4b +B7a 
R8d +B6b and it is hard for white to defend against +Bx7c. Sato 
had seen this, but he feared 62.Sx4e S*6d Gx6d Bx6d N*6a!. This 
is a very Sato-like move, but Habu didn't like it much. Habu said 
after the game that he would not have played it like that.

62.G6c-7d    07:30:00  06:36:00
63.B7e-9g    07:40:00  06:36:00

65.B9gx8f    07:40:00  06:47:00
66.B*5e!     07:40:00  06:49:00

Now white suddenly has a big advantage.

71.R4g-2g    07:42:00  07:10:00
72.G7d-8e    07:42:00  07:18:00
73.P6d-6c+   07:44:00  07:18:00
74.G8ex8f    07:44:00  07:18:00
75.P8gx8f    07:49:00  07:18:00
76.B*3f      07:49:00  07:19:00

Game over. Sato tries a desperate attack, but he needs too much 
material to fuel this attack and Habu wins easily in the counter-attack.

Final Diagram

Simple mate after 107.K8h G*8g or 107.K6g G*6h Sx6h G*6f. This game 
has the same pattern as the first two games: Sato plays the opening 
well and he gets his opening preparation on the board. After that, 
Habu finds a way to complicate the position and Sato makes a mistake 
that loses the game. A Sato in good form would be able to carry his 
opening preparation advantage over the finish line, but that is not 
happening in this match. Three down with four to play is quite a 
desperate situation and Habu seems to be taking back the Osho title 
he lost last year. The question is: will he do it in Oyama style? 
The late Oyama was well-known for getting very angry (in a positive way) 
at players who took a title from him, usually thrashing them 3-0 or 
4-0 in a return match. Game 4 will tell us if Habu has the same 
mercilessness.
