The reclining silver variation of the Bishop Exchange opening.
This is the most deeply analyzed opening in shogi and new moves are
often played very late in the game. This game is not an exception.

The end of the first day. We are still in known territory.

70.G4c-4b 04:11:00 03:59:00
71.P*2d! 04:19:00 03:59:00
Moriuchi's new move. In last year's preliminary round of the
Ryu-O tournament, he had played this position with white
against Maruyama. This game continued 71.Nx4e B*3g R3h B4f+
P4c+ Gx4c Bx1a+ +Bx4e and white won. Removing the knight on
4e seems to take the sting out of the black attack. It seems
that 71.P*2d was discovered during the post-mortem analysis of
this game, so it was basically a question whether Maruyama or
Moriuchi would play it first.
72.G2cx2d 04:19:00 05:00:00
73.N3gx4e 04:19:00 05:00:00
74.B*3g 04:19:00 05:02:00
75.R2h-3h 04:59:00 05:02:00
76.B3g-4f+ 04:59:00 05:03:00
77.N4e-3c+! 05:00:00 05:03:00
This is the point of sacrificing the pawn on 2d on the 71st
move. 78.Gx3c Px3d G2dx3d Rx3d Gx3d P4c+ is good for black, so
white has to take with the knight. If the gold would still be on
2c instead of 2d, white could take this knight simply with G2cx3c.
78.N2ax3c 05:00:00 05:54:00
79.P3ex3d 05:01:00 05:54:00
80.G2dx3d 05:01:00 05:57:00
It seems that this was a change of plan by Habu. He originally
thought that he could play 80.P*3g here.
81.R3hx3d 05:09:00 05:57:00
82.N*5d 05:09:00 05:57:00
This is the counter attack that white has put all his hopes on, but...
83.B6f-8d! 05:28:00 05:57:00
Great move. This seems to just give up the bishop for nothing, but
after 84.Rx8d, the rook no longer works sideways in defense and
the white position crumbles. For example, 84.Rx8d S*4c S*3b
(N6f is simple mate after Sx4b+ Kx4b G*4c K5a G*5b) Sx3b+ Kx3b
S*4c Gx4c Px4c+ Kx4c G*4d K5b Rx3c+ threatens a mate in three,
so white has no time to attack himself.
84.S*3b 05:28:00 06:24:00
85.S*5a 05:58:00 06:24:00
86.G4b-5b? 05:58:00 06:50:00
The decisive mistake. Here white's best chance was to take the
bishop. Now 86.Rx8d Sx4b+ Kx4b G*4c Sx4c Px4c+ Kx4c G*4d looks
very much like the variation above, but there is an important
difference: black has a silver in hand instead of a gold. Therefore,
white can now play K5b, and because Rx3c+ is no longer a mating
threat, white can answer Rx3c+ with N6f which is threatening mate
(after G*6i next). So, instead of Rx3c+, black must play Gx5d Px5d
Rx3c+, but it is still not completely clear if black can win this
position.
87.P*2d 06:03:00 06:50:00

95.G6bx5a 06:32:00 07:40:00
96.B*5f 06:32:00 07:40:00
97.G*4c 07:00:00 07:40:00
Moriuchi takes his time to make sure that his first Osho title does
not slip away. This is not mate, but takes away the promoted bishop on
4f, after which white has no attack anymore.

109.K7ix7h 07:03:00 07:42:00
Resigns 07:03:00 07:42:00
Black has the double mating threat B*2a and B*3d. If white defends with
110.S*2c then B*2a Kx2b G*3b is mate. Also, there is no mate. For example
110.N*5f K6g S*7h K5f G*4f K5e and the king escapes up the board. Habu
resigns the game and the match and now for the first time in eleven years
only has two titles left. Moriuchi, on the other hand, becomes a double
title holder for the first time in his career. He can make it three if
he can beat Habu in the Meijin match.
