32.K3a-2b    00:41:00  01:21:00

An orthodox Yagura opening in this decisive game. Black has 
the higher winning percentage, so it seemed likely that Habu 
had prepared something.

48.P4d-4e    02:41:00  04:29:00

The sealed move. This is still a known position.

50.S2dx2e    02:59:00  04:29:00

58.S*6d      03:32:00  05:36:00

Diagram 1

This is a new move, but not really an improvement. Habu himself 
also characterized it as very painful to play. With this move, 
white drops a precious silver in a defensive position, blocks 
the escape route of the bishop and also makes the natural attack 
P6d followed by P6e impossible. It remains unclear what he had 
prepared, but here he realized that his opening strategy had failed. 
The obvious way to play here would be 58.B6d, but after Bx6d Px6d P3e 
G4d P2d Px2d P*2e white is in trouble (Px2e P*2d followed by B*4a and 
S*2c is very quick and impossible to defend). Still, despite the drawbacks 
of S*6d, white is a knight up and even though the pieces are all blocking 
each other, white can still hope to win if he can free them and use them 
in attack.

59.P*7b!     04:07:00  05:36:00

Strong move. Dropping a pawn so far from the king seems too slow, but 
white has no proper attack here. This pawn can not be taken: 60.Rx7b 
S*8c R7a P*7b R8a Sx7d+ is good for black. Also, defending against the 
pawn promotion with 60.R8a is bad after S*6b which threatens both P7a+ 
and Sx7c+. Because P7a+ is next, white has to move quickly. However, 
another point of P*7b is that even if black has no time to promote this 
pawn, the sideways working of the rook is now blocked and attacking the 
white king becomes much easier.

60.G3d-4e    04:07:00  05:44:00
61.B4f-1i    04:45:00  05:44:00
62.S4b-3c    04:45:00  05:45:00
63.P3f-3e    04:53:00  05:45:00
64.P*3f      04:53:00  05:50:00
65.S*5b      05:03:00  05:50:00
66.G4ex3e    05:03:00  05:58:00
67.S5bx6c+   05:13:00  05:58:00
68.P5d-5e    05:13:00  06:00:00
69.G6g-7f!   06:12:00  06:00:00

Diagram 2

Another good move by the Meijin. Black has just taken the pawn on 6c, which 
means that white has the extra attacking plan of P*6e now. Moriuchi defends 
against this and at the same time puts pressure on the white bishop. Black 
now threatens to bring the bishop on 1i into play with +Sx6d Bx6d Bx5e. Also, 
at the right time, Gx7e Sx7e Bx5e is a possibility. Again, white is forced 
into action.

70.P8e-8f    06:12:00  06:59:00
71.P8gx8f    06:47:00  06:59:00
72.N7c-6e    06:47:00  07:15:00

Sacrificing the knight for a desperate attack. White has no choice. 72.N4e is 
answered by 73.Gx7e Sx7e +Sx7c and B*6e next is a bishop that works great in 
attack and defense. No way that white's P3g+ will be in time. Black may have 
the better position, but white manages to set up an attack and the game is still 
reasonably close.

73.P6fx6e    06:56:00  07:15:00
74.N5cx6e    06:56:00  07:15:00

76.G3ex3d    07:35:00  07:23:00
77.N*2f      07:37:00  07:23:00

Diagram 3

78.N6ex7g+?  07:37:00  07:47:00

A mistake that puts Habu's hopes to become the 18th Lifetime Meijin on hold for 
at least another year. White should have played immediately 78.G4e here. Then 
79.+Sx6d (black wants to drop this knight on 3d) Nx7g+ Gx7g B6d N*3d is very 
similar to the actual game, but the important difference is that the bishop on 
6d is not under attack, so white can now play K3a.

79.G7hx7g    07:37:00  07:47:00
80.G3d-4e    07:37:00  08:24:00

After G4d or G3e, black takes the bishop and drops it on 7a.

81.N*3d      07:46:00  08:24:00

The difference. 82.K3a now fails to Gx7e.

82.S3cx3d    07:46:00  08:27:00
83.N2fx3d    07:46:00  08:27:00

86.G4e-4d    07:54:00  08:34:00
87.+S6cx6d   08:15:00  08:34:00

99.N*5g!     08:43:00  08:38:00

Diagram 4

The decisive move. White has no defense.

100.B*6g     08:43:00  08:38:00

This allows mate. Moriuchi probably saw it instantly, but he takes 6 minutes 
for his next move to check every variation multiple times.

101.N5gx4e   08:49:00  08:38:00
102.B6gx4e+  08:49:00  08:38:00

Final Diagram

Mate after 110.Kx3e G*4f Kx2e Gx3f etc., or 110.Kx2e R2h Any*2f B*3d etc. A straight 
victory by Moriuchi, who seemed to be the better player in this match. Habu had to 
go very deep to take this match to seven games, but in the end he came up short. 
Moriuchi defends a major title for the first time in his career, which also should 
give him a lot of confidence for the future.
