3.P1g-1f     00:04:00  00:00:00
4.P8c-8d     00:04:00  00:32:00
5.P6g-6f     00:16:00  00:32:00

11.R2h-6h    00:38:00  00:35:00

It seems like Habu was determined to surprise Sato for once, 
as he doesn't often play the Shikenbisha with black.

12.K5a-4b    00:38:00  00:35:00
13.S3i-3h    00:39:00  00:35:00
14.K4b-3b    00:39:00  00:35:00
15.G6i-5h    00:49:00  00:35:00
16.S6b-5c    00:49:00  01:42:00
17.P4g-4f    01:04:00  01:42:00
18.P8d-8e    01:04:00  01:48:00
19.B8h-7g    01:04:00  01:48:00
20.P7c-7d    01:04:00  01:52:00
21.K5i-4h    01:37:00  01:52:00
22.B2b-5e    01:37:00  01:54:00

Aggressive, as always.

23.G5h-4g    01:59:00  01:54:00
24.P7d-7e    01:59:00  01:55:00
25.P7fx7e    02:00:00  01:55:00
26.S5c-6d    02:00:00  01:55:00
27.P7e-7d    02:00:00  01:55:00

This is a move that has been played only a couple of times before.

Diagram 1

This is a move that has never been played before. It looks like the 
game will now turn into an early fight, but both players are keeping 
a balance between attack and defense on the side of the rooks.

29.R6h-8h    02:07:00  02:20:00
30.R8b-7b    02:07:00  02:36:00
31.G4g-5f    02:26:00  02:36:00
32.B5e-3c    02:26:00  02:37:00
33.R8h-7h    02:29:00  02:37:00
34.R7bx7d    02:29:00  03:11:00
35.B7g-5i    02:39:00  03:11:00
36.N8a-7c    02:39:00  03:48:00
37.P*7f      02:52:00  03:48:00
38.S7e-6d    02:52:00  03:51:00
39.G5f-4e    02:54:00  03:51:00

This is a strong attack. Normally the Furibisha side attacks from the 
side, but here Habu shows that an attack at the head of the king is 
also possible.

40.K3b-2b    02:54:00  04:05:00
41.K4h-3i    03:04:00  04:05:00
42.G4a-3b    03:04:00  04:07:00
43.K3i-2h    03:12:00  04:07:00
44.L1a-1b    03:12:00  04:26:00

To move away from the pressure, Sato changes his castle into an Anaguma.

45.B5i-7g    03:36:00  04:26:00
46.K2b-1a    03:36:00  04:28:00
47.G4ex3d    03:38:00  04:28:00
48.B3c-2b    03:38:00  04:28:00
49.P2g-2f    03:38:00  04:28:00
50.P5d-5e    03:38:00  05:03:00
51.P2f-2e    03:45:00  05:03:00
52.S6d-6e    03:45:00  05:03:00
53.G3d-3e    03:51:00  05:03:00
54.S6ex7f    03:51:00  05:03:00
55.S6gx7f    04:38:00  05:03:00
56.R7dx7f    04:38:00  05:03:00
57.S*3d!     04:40:00  05:03:00

Important move. If 57.P2d Px2d and only then S*3d, white can answer 
S*2c and after Sx2c+ Gx2c S*3d S*3b the white attack can be stopped.

58.S*4d      04:40:00  05:16:00
59.P2e-2d    05:11:00  05:16:00
60.S4dx3e    05:11:00  05:24:00
61.P2dx2c+   05:11:00  05:24:00
62.P*3c      05:11:00  05:27:00
63.+P2cx3b   05:27:00  05:27:00
64.S3ax3b    05:27:00  05:27:00
65.G*2c      05:27:00  05:27:00
66.G*3a      05:27:00  05:28:00
67.G2cx3b    05:27:00  05:28:00
68.G3ax3b    05:27:00  05:28:00
69.S*2c      05:27:00  05:28:00
70.G*3a      05:27:00  05:30:00
71.S2cx3b+   05:27:00  05:30:00
72.G3ax3b    05:27:00  05:30:00
73.G*2c      05:27:00  05:30:00

It looks like Habu is attacking strongly, but with the strong counter 
threat of P*2g, his attack is not strong enough to succeed. Sennichite 
is the only possible conclusion.

74.S*3a      05:27:00  05:31:00
75.G2cx3b    05:27:00  05:31:00
