Diagram 1

A Kakugawari with tempo loss opening, and this particular variation has 
been studied for quite some time. This position was first played in August 
2003 in the challenger tournament of the Ryu-O between Tanigawa and Yamasaki. 
In that game it followed 51.G4h and after 52.Px6f Px7d B4f G4g P*7g Sx7g Nx7g+ 
Gx7g S*3f! Gx3f Bx5g+ white had the better position even though Tanigawa 
managed to turn the tables and win.

51.G5h-4g!?  04:02:00  03:12:00

A new move by Fukaura, but it is unclear how good it is. The reasoning behind 
this move is simple: defending the knight on 3g and at the same time defend 
against B4f in the variation given above so that S*3f is not possible anymore.

52.P4e-4f    04:02:00  03:29:00

This is the disadvantage of 51.G4g: white can push up this pawn while attacking 
the gold. Still, this is not only good for white, because the pawn on 4f also 
blocks the bishop on 7c.

53.P7ex7d    04:20:00  03:29:00
54.B7c-6d    04:20:00  03:44:00
55.G4g-4h    04:20:00  03:44:00
56.P*7g      04:20:00  03:45:00
57.N8ix7g    05:18:00  03:45:00

Diagram 2

58.P6ex6f?   05:18:00  04:45:00

Probably a mistake. After the game Fukaura said he was worried about 58.Nx7g+ 
59.Sx7g 60.N*3f. This simple fork was of course also seen by Habu, but Habu 
didn't like 61.Px6e next, so he decided against the knight fork. However, after 
Px6e he may have given the move 62.B7e too little thought. For example, 63.P7c+ 
Nx4h+ +Px8b Bx5g+ N*6h P4g+ and even though black is ahead on material, the white 
attack looks pretty dangerous. It was probably Habu's best chance in this game. 
As it was, Habu said after the game that there was not a single position in this 
game where he thought he was better.

59.B*7c      05:38:00  04:45:00
60.B6dx7c    05:38:00  04:46:00
61.P7dx7c+   05:38:00  04:46:00
62.R8b-8a    05:38:00  04:46:00
63.B*7d!     05:44:00  04:46:00

This is a strong bishop drop that gives black the advantage.

64.G5b-5a    05:44:00  05:08:00

Trying to make it as hard as possible. For example, 64.G5b-4c +P7b R5a P*6c and 
white has no defense against the tokin attack.

65.+P7c-7b   06:08:00  05:08:00
66.P*7f      06:08:00  05:09:00
67.N7gx8e    06:24:00  05:09:00
68.P8dx8e    06:24:00  05:09:00
69.S8fx8e    06:24:00  05:09:00
70.B*7g      06:24:00  05:48:00
71.+P7bx8a   07:07:00  05:48:00
72.B7gx9i+   07:07:00  05:48:00
73.R*7a      07:07:00  05:48:00
74.L*6a      07:07:00  05:48:00

Diagram 3

75.B7d-5b+!  07:09:00  05:48:00

Strong move. Black has to be very careful here, because his position has many 
weaknesses. Because of this, Fukaura thought that he had no choice but to attack, 
because any hesitation could be fatal.

76.G5ax5b    07:09:00  06:05:00
77.R7ax6a+   07:09:00  06:05:00
78.K3a-4b    07:09:00  06:05:00
79.N*6d!     07:20:00  06:05:00

Strong again. The black attack cannot be stopped, although Fukaura needs to 
find one more good move to win the game.

80.B*6c      07:20:00  06:18:00

If 80.B*9g K6h Bx6d +Rx6d N*3f would work, white would be OK, but then black has 
R2i which attacks the promoted bishop on 9i.

81.L*4e      07:33:00  06:18:00
82.P6f-6g+   07:33:00  06:57:00
83.G7hx6g    07:37:00  06:57:00
84.G5b-5a    07:37:00  06:59:00
85.P*4c      07:49:00  06:59:00
86.G3bx4c    07:49:00  06:59:00
87.+R6a-7a   07:49:00  06:59:00
88.P7f-7g+   07:49:00  07:04:00
89.G6gx7g    07:49:00  07:04:00
90.B6cx8e    07:49:00  07:04:00
91.P*6c!     07:49:00  07:04:00

Diagram 4

After game Fukaura said that only when he found this move, he thought that his 
attack would work. White cannot ignore this, because Rx5a+ is a mating threat.

92.B8ex6c    07:49:00  07:31:00

White has no choice but to pull back the bishop from the attack, which gives black 
enough breathing room to make his own attack work. White wants to play 92.Sx6c 
instead, but this fails to 93.Lx4d Gx4d Rx2c+. Also 92.P*6a +R8b N*6b Px6b+ 
Px6b P*7h is winning for black.

93.L4ex4d    07:49:00  07:31:00

Final Diagram

It is always a little bit special when a game is being resigned with the king on 
the central square 5e. This is mate after 128.K4d P*4e Sx4e G*5e or 128.K6f G*7g 
K5g G*5h so Habu had no choice. A great start for challenger Fukaura to take 
the first two games of this match. Habu already faces a must-win situation in 
the third game to avoid an almost unrecoverable 0-3 abyss.
