6.B2b-3c     00:01:00  00:03:00
7.S3i-4h     00:01:00  00:03:00

10.R8b-4b    00:15:00  00:09:00
11.K5i-6h    00:25:00  00:09:00
12.S3a-3b    00:25:00  00:14:00
13.K6h-7h    00:27:00  00:14:00
14.S7a-7b    00:27:00  00:23:00
15.P5g-5f    00:34:00  00:23:00
16.S3b-4c    00:34:00  00:27:00
17.S4h-5g    00:54:00  00:27:00
18.P9d-9e    00:54:00  00:40:00
19.P3g-3f    01:14:00  00:40:00

For the first time Maruyama is going to try to build an anaguma against 
Tanigawa's Shikenbisha opening. Of course Tanigawa doesn't know this yet, 
and that is the point of playing 19.P3f first. This gives black the option 
of playing a quick attack, which is bad for white if the king is still on 
5a, so white more or less has to play the next move.

20.K5a-6b    01:14:00  00:43:00

With the king on 5a, it is hard for black to play the anaguma as the Fujii 
system is very strong. However, with the king on 6b, the white camp is 
vulnerable, so a quick attack against the anaguma is risky.

21.B8h-7g    01:17:00  00:43:00
22.K6b-7a    01:17:00  00:51:00
23.K7h-8h    01:29:00  00:51:00
24.K7a-8b    01:29:00  01:05:00
25.L9i-9h    02:14:00  01:05:00
26.R4b-3b    02:14:00  02:01:00

This is an attacking plan against the anaguma that was popular two or 
three years ago. If black tries to complete the anaguma with 27.K9i, 
then white can launch a strong attack with P3e followed by P4e.

27.P5f-5e    02:49:00  02:01:00

Maruyama closes the bishop's diagonal, giving white no opportunity for a 
quick attack. From now on the game was expected to continue at a slow 
pace, but Tanigawa has other plans.

28.G4a-5b    02:49:00  02:57:00
29.K8h-9i    02:57:00  02:57:00
30.P5c-5d!?  02:57:00  03:28:00

Diagram 1

It's almost the end of the first day and Tanigawa decides to open the game 
early. There have been games with 30.B5a S4f P6d, but this is a new move 
(or better, a new attacking strategy).

31.S5g-5f    04:00:00  03:28:00
32.P5dx5e    04:00:00  04:07:00
33.S5fx5e    04:09:00  04:07:00
34.P*5d      04:09:00  04:13:00
35.S5e-6f    04:14:00  04:13:00
36.B3c-4b    04:14:00  04:15:00
37.B7g-6h    04:58:00  04:15:00
38.B4b-6d    04:58:00  04:15:00
39.P*5e      06:03:00  04:15:00
40.P5dx5e?   06:03:00  05:01:00

Diagram 2

A mistake that gives Maruyama the advantage. Pulling back the bishop 
with 40.B4b was the correct move. Black's threat of breaking through 
on the 2nd file is too dangerous. Probably Tanigawa's temperament 
didn't allow him to pull back a piece that he just moved out.

41.P2e-2d    06:08:00  05:01:00
42.P5e-5f    06:08:00  05:01:00
43.B6h-4f    06:17:00  05:01:00
44.P2cx2d    06:17:00  05:06:00
45.R2hx2d    06:18:00  05:06:00
46.P*2b      06:18:00  05:06:00
47.P*2c      06:40:00  05:06:00
48.B6dx4f    06:40:00  05:52:00

Both players wanted the opponent to take this bishop, so the fact that 
Tanigawa takes it is a clear indication that black has the advantage. 
Black will win a knight and even though his anaguma is incomplete, 
this is not enough compensation.

49.P4gx4f    06:40:00  05:52:00
50.B*3c      06:40:00  05:52:00
51.R2d-2g    06:43:00  05:52:00
52.P2bx2c    06:43:00  05:52:00
53.R2gx2c+   06:47:00  05:52:00
54.R3b-2b    06:47:00  05:52:00
55.+R2cx2b   06:49:00  05:52:00
56.B3cx2b    06:49:00  05:52:00
57.R*2h      06:51:00  05:52:00
58.B2b-3c    06:51:00  05:52:00
59.R2hx2a+   06:51:00  05:52:00
60.R*2d      06:51:00  05:52:00
61.+R2ax2d   08:01:00  05:52:00
62.B3cx2d    08:01:00  05:52:00
63.R*2a      08:05:00  05:52:00
64.B2dx4f    08:05:00  06:02:00
65.B*6e!     08:05:00  06:02:00

Diagram 3

In the press room all analysis was aiming for the standard B5e followed 
by N7d attack. 65.B*6e was a complete surprise. It must have surprised 
Tanigawa too, as he took more than an hour for his next move. 65.B*6e 
is an unusual move, but very strong. It is hard to defend against N*5e 
next. Also, this bishop works in defense.

66.P9e-9f    08:05:00  06:40:00
67.P9gx9f    08:05:00  06:40:00
68.P*9g      08:05:00  06:40:00
69.L9hx9g    08:05:00  06:40:00
70.P6c-6d    08:05:00  06:42:00
71.B6ex4c+   08:25:00  06:42:00
72.G5bx4c    08:25:00  06:42:00
73.N*6c?     08:25:00  06:42:00

Diagram 4

A mistake that lets Tanigawa back in. Better was 73.Rx1a+. After 
74.R*2h P*5i P5g+ Sx5g Bx5g+ L*6c P*2a Lx6a+ black keeps his advantage.

74.B*6b!     08:25:00  06:44:00

Now black's attack suddenly becomes quite difficult.

75.P*5b?     08:33:00  06:44:00

Very risky. This pawn can now no longer be used on 5i to keep the rook out.

76.R*4i?     08:33:00  06:47:00

Diagram 5

Too eager. Tanigawa realizes that he's back in the game and rushes his 
attack. If he would have played 76.P9e first, he would suddenly have 
good chances: 77.Px9e (P5a+ Px9f is good for white) R*4i S7h B7i+ S*5i 
(black can't play a pawn here) +Bx9g Nx9g P*9g K8h Px9g+ Kx9g and white 
can choose between N*8e and P7d, which both look very strong.

77.S7i-7h    08:34:00  06:47:00
78.P*9e?     08:34:00  07:28:00

If the right plan is played in the wrong order, often more than one 
move turns out to be bad. This is now the losing move. White would 
still have good fighting chances after 78.Rx6i+ Sx6i B7i+ R*6h P5g+
Sx5g P*9e Px9e +Bx9g Nx9g P*9f.

79.K9i-8h!   08:45:00  07:28:00

This early escape is winning. White can no longer get to the black king 
in time.

80.P9ex9f    08:45:00  07:42:00
81.L9gx9f    08:45:00  07:42:00
82.L9ax9f    08:45:00  07:42:00
83.P5b-5a+   08:49:00  07:42:00
84.L9f-9h+   08:49:00  07:46:00
85.K8hx9h    08:49:00  07:46:00
86.R4ix6i+   08:49:00  07:46:00
87.S7hx6i    08:49:00  07:46:00
88.B4f-7i+   08:49:00  07:46:00
89.S*8h      08:49:00  07:46:00
90.P*9g      08:49:00  07:58:00
91.N8ix9g    08:49:00  07:58:00
92.+B7ix6i   08:49:00  07:58:00
93.L*9f      08:49:00  07:58:00

Diagram 6

Drop where you're opponent wants to drop. This is a mating threat as well.

94.P*9c      08:49:00  08:12:00
95.R*9i      08:50:00  08:12:00
Resigns      08:50:00  08:18:00

Final Diagram

White has no way to attack and 97.+Px6a leaves him without defense. After 
6 minutes Tanigawa decides to resign. Maruyama bounces back from a bad game 
and ties the match at 2-2. Still, in this game there were some flaws as 
well even though Tanigawa didn't take the chances he was offered. One 
still feels that the momentum is with Tanigawa in this match, but the 
fifth game will be vital.
