The Yagura opening. "As planned" according to Habu. For a long time, 
this game will follow last year's epic 4th game Ryu-O battle between 
Abe and Habu. Black won this game after 257 moves, the longest game 
ever played in the Ryu-O tournament.

39.S5e-5d    02:57:00  00:53:00

Up until now, the game is identical to the game between Abe and Habu. 
In that game, Abe played 39.Px9f, but 39.S5d was considered to be a 
better move. Moriuchi must have analyzed this position thoroughly.

40.G4cx5d    02:57:00  01:34:00
41.R5hx5d    02:57:00  01:34:00
42.S6b-5c    02:57:00  01:34:00

45.G*8c      03:16:00  01:36:00
46.S7cx7d    03:16:00  01:40:00
47.G8cx9b    03:16:00  01:40:00
48.P9fx9g+   03:16:00  01:40:00
49.N8ix9g    03:25:00  01:40:00
50.P*5a!     03:25:00  02:36:00

Diagram 1

The move that Moriuchi found during his analysis a year ago. It is not 
completely clear how good it is, but Moriuchi now gets two important 
advantages. He catches Habu by surprise and he has only used a small 
part of his available thinking time.

51.P*5b      04:58:00  02:36:00

A difficult decision. Habu did not like this move very much, but also 
had no confidence in 51.Gx8a or 51.P*9f. Further analysis of this 
position has to show if white already has an advantage here.

52.R*4i      04:58:00  04:04:00
53.K7i-8h    04:59:00  04:04:00
54.S5c-6b    04:59:00  04:04:00
55.G9bx9c    05:13:00  04:04:00
56.N8ax9c    05:13:00  04:30:00
57.L*5i      05:13:00  04:30:00
58.B3a-6d!   05:13:00  04:32:00

Diagram 2

Well played. The main concern of the white position are the pieces 
on the 3rd file, which block to path of the king to safety on 2b. 
Moriuchi opts for riding the black attack to get his king safe.

59.P5bx5a+?!  05:40:00  04:32:00

Probably better was 59.R*9b. Then after 60.S7a P5a+ K3a R5b+ P*5h 
+P4a K2b +Rx5h black has the better position. This is just one example, 
but it seems that 59.R*9b holds more promises for black than 59.Px5a+.

60.K4a-3a    05:40:00  04:37:00
61.+P5a-5b!? 05:44:00  04:37:00

Most people in the press room expected 61.+P4a to move in on the white 
king (if white takes this promoted pawn, R*6a is devastating). Habu 
doubts the strength of his attack and decides to clear the left side 
of the board to create chances for entering king.

62.K3a-2b    05:44:00  05:28:00
63.R*7b      05:47:00  05:28:00
64.S6b-7c    05:47:00  05:35:00

68.P*5h      05:48:00  05:38:00
69.+R7cx7d   05:50:00  05:38:00
70.P5hx5i+   05:50:00  05:43:00
71.+R7dx6c   06:15:00  05:43:00
72.+P5i-5h   06:15:00  05:50:00
73.B6h-7i    06:15:00  05:50:00

74.B5cx9g+!? 06:15:00  06:40:00

A move that shows a lot of confidence. Kiriyama and Abe thought that 
white had to be patient here and play 74.B*4b instead. Then after 
75.P*5c Rx2i+ white has the strong N*5e next. Moriuchi took 50 minutes 
to decide that he could win with a quick attack.

75.L9ix9g    06:20:00  06:40:00
76.N9c-8e    06:20:00  06:42:00
77.B*5d      07:29:00  06:42:00
78.L*4c      07:29:00  07:02:00
79.P8g-8f    07:29:00  07:02:00

Diagram 4

In the press room 79.S*4a was analyzed, which seemed good for black. 
For example, 80.G4b P8f N*9e Px8e G*8g Gx8g Rx7i+ Kx7i Nx8g+ and now 
black has mate starting with R*3b. Therefore, it seems that playing 
S*4a before P8f makes an important difference. However, in the 
post-mortem analysis the following variation was found: 79.S*4a 
Nx9g+ Kx9g P*9f Kx9f L*9d P*9e G*8e K9g Lx9e K8h G4b and now black 
seems to have nothing else then +R7b, which white can easily defend 
with N*3b.

80.R4ix7i+!  07:29:00  07:16:00

A fine finish. This needed good judgment, as the attack is not easy.

81.G7hx7i    07:31:00  07:16:00
82.B*9i      07:31:00  07:18:00
83.K8h-7h    07:43:00  07:18:00

No choice. 83.Kx9i fails to the simple 84.Nx9g+ S*9h (P*9h N*8g) L*9f 
Sx9g Lx9g+ which leaves the black king without defense. It looks like 
black can escape up the board after 83.K8g, but then 84.Nx7g+ Gx7g 
S*9h K9f P*9d S*9e G*8e! Px8e Bx7g+ is hisshi.

84.N*5e      07:43:00  07:30:00
85.S*6h      07:43:00  07:30:00
86.+P5hx6h   07:43:00  07:40:00
87.G6gx6h    07:44:00  07:40:00
88.N8ex7g+   07:44:00  07:45:00
89.G6hx7g    07:44:00  07:45:00
90.B9ix7g+   07:44:00  07:45:00
91.K7hx7g    07:44:00  07:45:00
92.G*6g      07:44:00  07:45:00
93.K7g-8g    07:44:00  07:45:00
94.G*7g      07:44:00  07:45:00
Resigns      07:44:00  07:45:00

Final Diagram

Hisshi after 95.K9f S*9d. So far this match is a complete reversal of 
the Meijin match. Moriuchi is hitting Habu where he wants and his 
first Ryu-O title is on the way. The only question is: will Moriuchi 
be the first player to whitewash Habu 4-0?
