A big surprise. The Double Yokofudori is rare at this level. Actually, 
it is the first time that this opening has been played in a Meijin match. 
Recently, Miura (8-dan) has been giving it a try, but the general opinion 
is that it gives black the easier position.

19.S8h-7g    02:00:00  00:09:00
20.R7f-7d    02:00:00  00:25:00

24.P*8f      02:01:00  00:36:00

Diagram 1

This is what Moriuchi wanted to try, but we will probably never know what 
his real intentions were. In Habu's opening book series "Habu's Brain", the 
move 24.P*8f is also given and Habu concludes that after 25.P*8h P8g+ Px8g 
P*8b G3h black has the better position. Black has won a pawn and forced white 
to drop a pawn on 8b. Also, black can start an edge attack with P9f next. 
This was written 10 years ago, so there might be something with this variation 
that Moriuchi liked. Habu doesn't wait for it...

25.S7gx8f!   02:15:00  00:36:00

If this game is a good indication, this might be better than P*8h.

26.B*7c      02:15:00  02:26:00
27.B4fx7c+   03:23:00  02:26:00
28.N8ax7c    03:23:00  02:26:00
29.S8f-7g    03:23:00  02:26:00
30.K5a-5b    03:23:00  02:31:00
31.R*8a      03:37:00  02:31:00

Diagram 2

32.R*8e      03:37:00  03:58:00

This looks good, as white can move the knight out with tempo. However, Habu 
has judged correctly that this knight on 8e is going to be a liability. 
However, after 32.R*8b Rx8b+ Sx8b P*8c S7a R*8a white is even worse, because 
black has managed to make a dangling pawn with tempo.

33.R8ax8e+   03:53:00  03:58:00
34.N7cx8e    03:53:00  03:58:00
35.S7g-8h    03:53:00  03:58:00
36.P*8g      03:53:00  05:24:00
37.S8h-7i    03:59:00  05:24:00

Moriuchi has been using a lot of time here, but there is nothing for white to 
improve the position. White is attacking, but the knight on 8e has no power. 
It would have been a different story if the knight would have been on 6e.

38.B*4d      03:59:00  05:30:00

Diagram 3

39.P6g-6f!   05:37:00  05:30:00

Seems to open up the king position, but this is an important move, because 
after Bx6f, black can attack strongly with P*6d. The alternative 39.P*7g is 
not good because of 40.Nx7g+ Nx7g Bx7g+! Gx7g R*8i which is hard to defend. 
The bishop sacrifice is easy to overlook, but Habu has seen it.

40.P*2h      05:37:00  06:03:00
41.S3ix2h    05:41:00  06:03:00
42.B4dx6f    05:41:00  06:03:00
43.P*6d      05:43:00  06:03:00
44.B6fx9i+   05:43:00  06:13:00
45.P6dx6c+   06:08:00  06:13:00
46.K5bx6c    06:08:00  06:13:00
47.P*6d      06:10:00  06:13:00

Diagram 4

48.K6c-5d    06:10:00  06:37:00

No choice. 48.K5b fails to 49.B*6c K4b R*4a, 48.K6b to 49.R*6c K5b Rx6a+ Kx6a 
P6c+ and 48.Kx6d to 49.B*4f K6c B*9a+ (threatening L*6d) K5b P*6b Sx6b P*6c 
and black can use the lance at either 6d or cut off the king with L*3f. 48.K5d 
might be the best move, but the difference in king position shows who is 
winning here.

49.B*6c      06:39:00  06:37:00
50.K5d-4d    06:39:00  07:29:00
51.R*2d      06:39:00  07:29:00
52.P*3d      06:39:00  07:31:00

59.B6cx7d+   06:57:00  08:44:00

Diagram 5

The winning move.

60.+B8ix7h   06:57:00  08:44:00

Moriuchi decided to go out in a blaze of glory. 60.N*4d prolongs the agony, 
but 61.N*2d or 61.P5f Nx5f G*4f followed by Gx5f win easily for black.

61.S7ix7h    06:57:00  08:44:00
62.G*6h      06:57:00  08:48:00

68.N*6f      07:16:00  08:48:00

Resigns      07:16:00  08:48:00

Final Diagram

Clearly no mate and even if white picks up the promoted bishop on 7d after 
70.G*7g Sx7g Nx7g+ Kx7g R*7h K8f Rx7d+, the white king is mated after B*4f and 
G*5e. A convincing win by Habu to stop the rot after three consecutive losses. 
With his back against the wall he delivers, but he will need two more of this 
to take the Meijin title from Moriuchi, who is playing with the black pieces 
in game 6.
