1.P7g-7f     00:00:00  00:00:00

6.R8b-5b     00:01:00  00:05:00

It was more or less expected that Tanigawa would play this opening. 
He is a specialist in both the Kakugawari and the Gokigen Nakabisha 
and since the first game was a Kakugawari the Gokigen Nakabisha was a 
logical choice. Kondo, the man who basically invented this opening, was 
even in the press room to follow the game. This predictability also makes 
it easy to prepare and Moriuchi has indeed prepared well for this opening.

7.G4i-5h     00:02:00  00:05:00

The first surprise. This defense oriented move has not been played in a 
professional game for more than a year.

Diagram 1

This is still a theoretical position, but there is already a big difference 
in time here. Moriuchi has used 9 minutes so far, while Tanigawa used more 
than 2 hours. This difference is only getting bigger. This variation was 
actually written in a Kindai Shogi article written by Maruyama half a year 
earlier that was in the press room. Watanabe found the variation and just 
when they were looking at it, Moriuchi entered the press room while Tanigawa 
was thinking. Not uncommon, but it was of course bad if he would see the 
variations in the article, so they tried to hide it from him. Seeing this, 
he said: "Don't bother, I have read it". Making such a confident statement 
about opening preparation is very rare among top professionals.

24.S*4d      00:28:00  04:15:00

The alternative is 24.S*2b, but then 25.Nx6c+ Kx6c Bx9i+ Sx1a B*1h is good for 
black (for example P*5d is answered by L*6f).

25.B3cx4d+   00:50:00  04:15:00
26.P4cx4d    00:50:00  04:17:00
27.L*6f      00:52:00  04:17:00
28.S7a-7b    00:52:00  04:21:00
29.S*8b      01:00:00  04:21:00

Diagram 2

The end of the first day and we are still in Maruyama's article (this variation 
never appeared in a professional game, though). Maruyama gave 30.P*5g and after 
31.Gx5g +Bx8i Sx8a= N*4e Sx7b+ Kx7b Nx6c+ K8a S*7b Gx7b +Nx7b Rx7b N*6d his 
conclusion was that black is winning, but analysis in the press room showed 
that things are not easy after R7a G*7b K9b Gx7b P9d. It might even be that 
white is better in this position. We will never know if Moriuchi had something 
up his sleeve here or if he trusted Maruyama's judgment, because after another 
long think, Tanigawa played something different.

30.L*5d?     01:00:00  06:11:00

The first day has ended with a difference of five hours on the clock (Morichi 
1 hour used, Tanigawa more than 6 hours used). This, combined with the fear that 
Moriuchi has something prepared invites the mistake. The general opinion was that 
he should have tried his luck with 29.P*5g here.

31.N5e-4c+   01:32:00  06:11:00
32.R5b-5a    01:32:00  06:11:00
33.S8bx8a+!  01:51:00  06:11:00

Diagram 3

Subtle play. The obvious move is 33.Sx8a=, which attack the silver on 7b. The 
difference is clear after 33.Lx5f P*5g Lx5g+ Gx5g Rx5g+ L*5h. With a promoted 
silver on 8a, the rook can not move because of N5c+ K5a N*4c mate. Blocking the 
escape route of the king to 7a is more important than attacking the silver on 7b.

34.S7bx8a    01:51:00  06:23:00
35.N*5c      01:52:00  06:23:00
36.S*7b      01:52:00  07:02:00
37.+R1a-1b   03:39:00  07:02:00

An obvious move, but Moriuchi took 107 minutes for it, probably to make sure that 
Tanigawa was unable to think about his position during the lunch break.

38.P*2b      03:39:00  07:02:00
39.P*2c      03:40:00  07:02:00

Diagram 4

40.L5dx5f?   03:40:00  07:19:00

Pressed for time, Tanigawa rushes his attack. Here 40.S3b was his only chance. 
For example, 41.Nx6a+ Kx6a +Rx2b G3a +N5c K7a and it seems that the white position 
will fall apart easily, but this is not the case. During the post-mortem, Moriuchi 
gave Lx6c+ (after K7a) Gx2b G*6b K8b +Lx7b Sx7b Gx5a and it seems that black is 
better, but still the outcome is not completely clear.

41.P2cx2b+   04:24:00  07:19:00
42.S3a-4b    04:24:00  07:34:00
43.+P2b-3b   04:36:00  07:34:00
44.L5fx5h+   04:36:00  07:56:00
45.G6ix5h    04:36:00  07:56:00
46.R5ax5c    04:36:00  07:57:00
47.+N4cx5c   04:44:00  07:57:00
48.S4bx5c    04:44:00  07:58:00
49.P*5d!     05:02:00  07:58:00

Diagram 5

Moriuchi plays this game very accurately. Taking the gold immediately with 49.+Px4a 
has the problem that after 50.K7a P*5d the silver can move back to 6b. After 49.P*5d, 
the game is over and Moriuchi's only concern the rest of the way is how to make the 
game finish during the afternoon television broadcast.

Final Diagram

A rather long, but very straightforward mate after 70.K8a Gx7b Kx7b +R5b G*6b 
(S*6b +R6a) G*8b Kx8b +Rx6b G*7b S*7a K9c N*8e K8d G*7e K9e L*9f. A complete 
victory for Moriuchi, who takes a commanding 2-0 lead in this match. Tanigawa 
now desperately needs to win game 3 to keep this match interesting.
