8.B2bx8h+    00:02:00  00:08:00

The furigoma gave Sato the black pieces. This was the fifth time the 
pawns were tossed in the summer matches between Habu and Sato (Kisei, Oi 
and Oza). In all cases the tokins came up in majority, giving the black 
pieces to the challenger. Habu selects the Kakugawari with tempo loss, 
not the first time they play this opening. The game now follows the first 
game of the Kisei match for a long time, with the important difference that 
Habu was black in that game.

53.P9fx9e    03:34:00  03:58:00

The sealed move and the position is still identical to the Kisei match 
game. Following a game for such a long time is not unusual, but in the 
recent games between Habu and Sato, new early opening ideas have been 
the rule rather than the exception. Therefore, this development is a 
little unexpected.

54.P7d-7e    03:34:00  03:59:00

Diagram 1

55.P7fx7e?   04:18:00  03:59:00

Sato is the one who plays differently. In the Kisei match Habu played 
55.Sx7e and won a difficult and close endgame. After the game, Sato said 
that that he always intended to play differently, but he had also to admit 
that this was not the position to change the moves. On the surface, Px7e 
doesn't look bad. Of course there is the danger of drops on 7f or 6f, but 
with the silver still on 8f the black position is stronger against a pawn 
drop on 7g and an edge attack. 56.B*6f seems like a strong move, but after 
57.S7g the bishop gets in trouble.

56.P3d-3e    04:18:00  04:45:00

Changing the focus of attack to the other side of the board.

57.B7c-4f+   04:24:00  04:45:00

If black manages to make this promoted bishop work, he will get the advantage.

58.B*8b      04:24:00  04:47:00

Looks dangerous, but when the bishops are exchanged white has the threat 
of Px3f, so this is possible.

59.P6e-6d    04:36:00  04:47:00

Sato is having nothing of the bishop exchange and he is probably right: 
59.+Bx8b Rx8b B*7c R7b B4f+ (black has to defend 3f, so no time to take 
the lance) B*6f looks good for white. Taking on 3f is still possible and 
the rook on 7b is also ready to attack. Still, 59.P6d gives white another 
opportunity to activate his pieces.

60.R8a-6a    04:36:00  04:47:00

Now the pawn on 6d is difficult to defend.

61.G5h-6g    05:16:00  04:47:00
62.P*6f!     05:16:00  04:57:00

Diagram 2

Unexpected, but strong. In the press room only 62.Bx6d was analyzed. Then 
63.+Bx6d Rx6d B*7c and when the rook moves Bx8d+ Px3f leads to a difficult 
position.

63.G6gx6f    05:20:00  04:57:00
64.B8bx6d    05:20:00  04:57:00
65.+B4fx6d   05:21:00  04:57:00
66.R6ax6d    05:21:00  04:57:00

The point of 62.P*6f now becomes clear. With the gold hanging on 6f, B*7c 
is not possible. The really difficult move still has to come, though...

67.P*6e      05:21:00  04:57:00
68.R6d-6a!   05:21:00  04:57:00

Diagram 3

Innocent (maybe even weak) looking move, but brilliant. Black has three pawns 
and a bishop in hand, which seems to give him all kind of attacking possibilities 
like P2d, P4d and/or B*5b. Not a position in which to give the initiative to the 
opponent and even Sato thought that there must be something for black here. There 
isn't and Habu was the only one to make the correct judgment here. Because of the 
threat Px3f and the hanging gold on 6f, black can do nothing with the initiative 
in this position. 

69.P2e-2d    05:28:00  04:57:00
70.P2cx2d    05:28:00  05:25:00
71.P*2c      05:35:00  05:25:00
72.G3bx2c    05:35:00  05:27:00
73.P*2e      06:16:00  05:27:00
74.B*5i!     06:16:00  05:54:00

Painful drop. Games between Habu and Sato are often decided at the very end, but 
here Habu already felt that he was winning.

75.R4h-3h    06:17:00  05:54:00

With the rook tied to defensive duties, the black attack loses all its power.

76.P*9h      06:17:00  06:03:00
77.L9ix9h    06:19:00  06:03:00
78.P3ex3f    06:19:00  06:04:00
79.P2ex2d    06:26:00  06:04:00
80.G2cx2d    06:26:00  06:11:00
81.P*2e      06:32:00  06:11:00
82.G2d-2c    06:32:00  06:15:00
83.P4e-4d    06:33:00  06:15:00

85.S5f-4e    06:33:00  06:15:00
86.P*9g      06:33:00  06:29:00
87.L9hx9g    06:33:00  06:29:00
88.P3fx3g+   06:33:00  06:49:00
89.S4ex5d    06:33:00  06:49:00
90.G4cx5d    06:33:00  06:49:00
91.R3h-5h    06:33:00  06:49:00

Diagram 4

It seems like winning this position is still difficult, but Habu again shows why 
he is stronger than anybody else.

92.P*7g!     06:33:00  06:52:00

Looks like overdoing it, but Habu knows what he is doing.

93.N8ix7g    06:34:00  06:52:00
94.B5ix7g+   06:34:00  06:54:00

97.S8fx7g    06:34:00  06:55:00
98.N*8e      06:34:00  06:57:00

Black has sacrificed the bishop, but the tokin on 3g makes sure that the black 
king has no escape route.

99.B*4c      06:36:00  06:57:00

Final Diagram

Again Sato plays on until the mate is almost too simple: 117.K7c G*6b K8b (K6d G6c) 
G9b or 117.Kx8e P*8d K9f G*8e. A bit of a disappointing finish to an exciting match, 
as this game was all Habu from the moment the moves were different from the first 
game of the Kisei match. Habu shows a lot of nerve and fighting spirit to come back 
from 2-0 and 3-2 down in this match with his 11th Oi title as reward.
