1.P2g-2f     00:00:00  00:00:00
2.P3c-3d     00:00:00  00:00:00
3.P7g-7f     00:03:00  00:00:00
4.P5c-5d     00:03:00  00:02:00
5.P2f-2e     00:05:00  00:02:00
6.R8b-5b     00:05:00  00:05:00

No surprises in the opening in this Osho match. Kubo plays his favorite opening with 
white, the Gokigen Nakabisha, like in the first game.

7.S3i-4h     00:06:00  00:05:00
8.P5d-5e     00:06:00  00:12:00
9.K5i-6h     00:07:00  00:12:00
10.B2b-3c    00:07:00  00:15:00
11.P3g-3f    00:09:00  00:15:00
12.K5a-6b    00:09:00  00:21:00
13.S4h-3g    00:10:00  00:21:00
14.K6b-7b    00:10:00  00:32:00
15.S3g-4f    00:11:00  00:32:00

Like in the first game, Toyoshima moves up the left silver early, which is the most 
popular strategy against the Gokigen Nakabisha at the moment.

16.S3a-3b    00:11:00  00:48:00
17.K6h-7h    00:12:00  00:48:00
18.P5e-5f    00:12:00  00:48:00

This is different from the first game. There, Kubo played 18.K8b in this position.

19.B8hx3c+   00:20:00  00:48:00
20.S3bx3c    00:20:00  00:48:00

30.B*3b      00:48:00  00:51:00
31.+B4cx3b   01:10:00  00:51:00
32.G4ax3b    01:10:00  00:51:00
33.R2h-5h    01:10:00  00:51:00

Diagram 1

This is still opening theory. In general, exchanging the rooks is good for the 
Furibisha side, but this is an exception. After 34.Rx5h+ G6ix5h! it is actually 
the white position that has more holes for a rook drop, so white cannot play 
the rook exchange here.

34.P*5e!     01:10:00  00:56:00

This is the move that Kubo prepared. Here, 34.P*5f is the most natural looking 
move and this is what was played in earlier games. However, then white has a serious 
problem after 35.G6h K8b P*5b! and after both Rx5b B*4a R6b Rx5f or Gx5b Rx5f, white 
loses the important pawn on 5f. The idea behind Kubo's 34.P*5e is to defend against
P*5b. After all, if black again plays 35.G6h K8b P*5b then Gx5b is possible because 
Rx5e fails to B*4d, so black cannot touch the pawn on 5e.

35.G6i-6h    01:39:00  00:56:00
36.K7b-8b    01:39:00  01:10:00
37.S7i-8h    02:51:00  01:10:00

Played after 1 hour and 12 minutes. After the game, Toyoshima explained that he really 
wanted to play 37.P*5d here, but that he abandoned this idea because he didn't like 
38.G6b Rx5e B*4d R5i Bx9i+ S8h +B9h B*7g L*8d.

38.S7a-7b    02:51:00  01:20:00
39.S8h-7g    02:51:00  01:20:00

41.P9g-9f    03:23:00  01:55:00
42.P5e-5f    03:23:00  02:13:00
43.P*5b      03:39:00  02:13:00
44.R5ax5b    03:39:00  02:14:00
45.B*4a      03:39:00  02:14:00
46.R5b-4b    03:39:00  02:14:00
47.B4a-8e+   03:39:00  02:14:00
48.S3c-4d    03:39:00  02:15:00
49.R5hx5f    03:53:00  02:15:00
50.P4e-4f    03:53:00  02:16:00
51.S3gx4f    03:55:00  02:16:00

54.P*5b      03:56:00  03:05:00
55.N2i-3g    04:07:00  03:05:00
56.B2hx1i+   04:07:00  03:06:00
57.+B8e-7e   04:07:00  03:06:00
58.R4b-4a    04:07:00  03:27:00

The sealed move. This is a rather complicated position. White has won material by 
taking the lance on 1i, but black has compensation because his promoted bishop is 
much better placed than the white one. Neither player felt very confident about 
its own position, but it is clear that black is the one who has to force the attack, 
because he cannot give white time to activate the promoted bishop. If white can 
succeed in doing that, black will just be down in material.

59.+B7ex6d   04:08:00  03:27:00

Diagram 2

60.P3d-3e!   04:08:00  03:37:00

This gives white a clear plan to develop the bishop and also creates an important 
weakness on the head of the knight.

61.P3fx3e    04:13:00  03:37:00
62.+B1i-1h   04:13:00  03:40:00

White wants to get this bishop to 3e. Black has to move quickly to avoid this.

63.G4i-5h    04:59:00  03:40:00
64.+B1hx1g   04:59:00  03:49:00
65.P*2b      05:13:00  03:49:00
66.G3bx2b    05:13:00  04:06:00
67.S4f-5e    05:13:00  04:06:00
68.L*6b      05:13:00  04:20:00
69.+B6d-8f   05:23:00  04:20:00
70.P*6f!     05:23:00  05:02:00

Diagram 3

An important pawn sacrifice. 71.Px6f is impossible because it opens the diagonal 
to the king after which +Bx3e is not only developing the promoted bishop, but also 
strongly threatening +B3d next.

71.S7gx6f    05:25:00  05:02:00
72.S4dx5e    05:25:00  05:06:00
73.S6fx5e    05:28:00  05:06:00
74.P*3f      05:28:00  05:28:00

Sacrifices the rook, but Kubo has seen that he gets more than enough in return.

75.S*4b      05:50:00  05:28:00
76.R4ax4b    05:50:00  05:28:00
77.+B8fx4b   05:50:00  05:28:00
78.P3fx3g+   05:50:00  05:28:00
79.P5d-5c+   05:50:00  05:28:00
80.P5bx5c    05:50:00  05:28:00
81.P*5b      05:50:00  05:28:00
82.S*6e      05:50:00  06:00:00

Diagram 4

83.R5f-4f?   06:03:00  06:00:00

This cannot be even called a big mistake, but it is a decisive one. Toyoshima should 
have played 83.P5a+ instead. Of course he had seen this move, but he thought that 
white could ignore it. However, the post-mortem analysis showed that after 84.Sx5f 
+Px6a Sx6a R*4a the white king cannot be properly defended. Therefore, Kubo said that 
he intended to play 84.G7a, but then 85.R4f is much better than in the game. We will
 see a little later why that is the case.

84.P*4e      06:03:00  06:01:00
85.R4fx4e    06:03:00  06:01:00
86.+P3g-4h   06:03:00  06:08:00
87.P5b-5a+   06:50:00  06:08:00

Too late, but black didn't have much choice. The alternative 87.Gx4h N*5f is too 
strong. After that, it is best to save the king side gold with G7g, but after +B2g 
R4c+ G3c the inactive gold on 2b enters the fight strongly and white has the better 
position. In this variation we can see the difference if 83.P5a+ G7a is played before 
R4f. With the gold on 7a, the pawn on 5b is no longer defended, so G3c can be answered 
by +Rx5b, resulting in a difficult position after +B6c G5h.

88.+P4hx5h   06:50:00  06:13:00
89.G6hx5h    06:50:00  06:13:00

112.P*5b!    07:42:00  07:37:00

Diagram 5

This defensive tesuji decides the game. 113.+Rx5b is answered by 114.G*6b and the 
white defense is very hard to break down. However, even if black doesn't take the 
pawn on 5b, the attack is slowed down too much.

Final Diagram

Nice mate after 125.Kx8f B*7e Kx7e +Nx6e K8f L*8d K9g Lx8g+ so Toyoshima resigned 
here. Kubo didn't seem to be rattled by dropping the second game to the young challenger, 
because he played a flawless game to take the lead in the match again. Now the pressure 
is on Toyoshima to convert with the white pieces in game four or face a tough 1-3 deficit.
