1.P7g-7f 00:00:00 00:00:00
2.P3c-3d 00:00:00 00:06:00
3.P2g-2f 00:05:00 00:06:00
4.G4a-3b 00:05:00 00:09:00
5.P2f-2e 00:11:00 00:09:00
6.B2bx8h+ 00:11:00 00:15:00
For this vital game, Tanigawa decides to play the Kakugawari with
tempo loss. The Furibisha openings he tried earlier have not been
successful, so he is trying to change the flow of the match.

18.P9c-9d 02:07:00 02:02:00
19.S3h-3g 02:37:00 02:02:00
A quick attack. A logical choice against the white strategy. In a
slow build-up the loss of tempo does not make much difference and
the counter attack N7c-N8e becomes a significant extra option for
white. By attacking quickly, black hopes to cash in on his two-move
advantage.
20.S6b-7c 02:37:00 02:14:00
21.S3g-4f 02:44:00 02:14:00
22.P8d-8e 02:44:00 02:26:00

27.S4fx3e 03:23:00 03:12:00
28.P7d-7e 03:23:00 03:12:00
29.P7fx7e 04:34:00 03:12:00
The sealed move.
30.S6dx7e 04:34:00 03:14:00
31.P2e-2d 04:35:00 03:14:00
32.P2cx2d 04:35:00 03:26:00
33.S3ex2d 04:43:00 03:26:00
34.B*6d 04:43:00 04:15:00
35.B*3g 05:27:00 04:15:00
A change of plan. Habu intended to play 35.P*3g here, but he suddenly
saw that white then has 36.Sx2d Rx2d P*2c R2f P*7f Sx7f P8f Px8f P*8h
Gx8h Sx7f Rx7f Bx8f and white has the advantage. The threat is S*6h
and if black defends with P*7g then Bx7g+! is a strong reply. Taking
the bishop with the rook or knight fails to S*6h, while Gx7g fails
to S*8h.
36.S3cx2d 05:27:00 04:50:00
37.R2hx2d 05:27:00 04:50:00
38.P*2c 05:27:00 04:50:00
39.B3gx6d 05:28:00 04:50:00
40.P6cx6d 05:28:00 05:48:00
41.R2d-2e 05:31:00 05:48:00
42.P*7f 05:31:00 05:48:00
In the press room 42.P8f was analyzed, which seems to be good for
white. For example, after 43.Rx7e (Px8f Sx8f just helps white developing
the silver) Px8g+ P*8c Rx8c S*7b +Px7h Kx7h white has the brilliant
S*5h! (Gx5h is mate after B*8g etc.). After the game, 42.P8f was analyzed
extensively, but no conclusion could be reached.
43.S7g-8h 05:53:00 05:48:00
44.S*6e 05:53:00 05:49:00
45.B*4f 06:17:00 05:49:00
46.B*3f 06:17:00 06:25:00
47.R2ex6e 06:42:00 06:25:00
48.B3fx4g+ 06:42:00 06:25:00
49.R6ex7e 06:47:00 06:25:00
50.+B4gx4f 06:47:00 06:25:00
51.R7ex7f 06:47:00 06:25:00
Black has two silvers for the bishop and according to the proverb this
should be better for black. However, in this position the white position
has good balance and the position is unclear.
52.+B4fx5g 06:47:00 06:29:00
53.S*6h 06:59:00 06:29:00
54.P*7e 06:59:00 06:54:00
55.S6hx5g 07:13:00 06:54:00
56.P7ex7f 07:13:00 06:54:00
57.B*5e 07:13:00 06:54:00
58.B*4g? 07:13:00 07:08:00
A mistake that makes things difficult for white. After the game, Tanigawa
said that he deeply regretted this move and wished that he had played
58.B*2g instead. If black defends with 59.P*3h, then B3f+ P*5h R*2e is
hard to defend against. Furthermore, 59.S*3h is met by Bx3h+ Gx3h R*4i
S*6i S*5h G6h Sx6i+ Gx6i S*5h P*5i Sx6i+ Kx6i Rx2i+ G4h and Habu admitted
that he did not have much confidence in the black position.
59.S*5h 07:13:00 07:08:00
60.B4gx2i+ 07:13:00 07:09:00
61.P*5d! 07:13:00 07:09:00
The move that Tanigawa had overlooked. This creates a huge hole on 5c,
which can be used for a devastating silver drop later. Although the
position is objectively still rather difficult, Tanigawa might have
been shocked that he overlooked this, inviting the decisive mistake.
62.P5cx5d 07:13:00 07:27:00
63.B5ex1a+ 07:13:00 07:27:00
64.N2a-3c? 07:13:00 07:31:00
This is the decisive mistake. The only chance was 64.+Bx1i 65.+Bx2a
66.L*7g!. Then 67.Nx7g Px7g+ Sx7g P*7f Sx7f P*7g Gx7g P*7e or 67.L*5c
K4b N*4e Lx7h+ Kx7h +B5e with a difficult position. In Tanigawa's defense,
it should be added that L*7g is a very hard move to play for a professional.
The wall silver on 8h is very bad and allowing this silver to move for
nothing is not good attacking style. The best attack is through the center,
but in this case Habu has put all his forces in this center, so the only
quick way to break through is via the attacking base on 7g.
65.L*3f 07:15:00 07:31:00
Now the black attack gains a lot of speed and white never gets a chance to
recover.

80.N*5c 07:38:00 07:49:00
81.S5gx5f 07:38:00 07:49:00
82.+B2ix5f 07:38:00 07:49:00
83.+B1a-4d 07:38:00 07:49:00
84.S*6e 07:38:00 07:49:00
85.L*7e 07:40:00 07:49:00
86.N4e-5g+ 07:40:00 07:52:00
87.G*7b 07:43:00 07:52:00
Resigns 07:43:00 07:52:00
No defense: 88.Gx7b +Rx5c or 88.S*5b Gx6b Kx6b +Bx5c etc. After 88.S*7d, black
has no mate, but Gx6b is a quick finish. After losing two Oi matches in a row
to Tanigawa, Habu finally succeeds. It is his 10th Oi title and he will be
happy to have two crowns again after holding only the Oza for three months.
Tanigawa will be disappointed, but not devastated, because after the first
game this match was all Habu.
