Notes by Reijer Grimbergen
1.P7g-7f
2.P3c-3d
3.P2g-2f
4.P4c-4d
5.P2f-2e
6.B2b-3c
7.S3i-4h
8.S3a-3b
9.P5g-5f
10.R8b-4b
11.K5i-6h
12.P9c-9d
13.K6h-7h
14.S3b-4c
15.P9g-9f
16.S7a-7b
17.G4i-5h
18.P6c-6d
19.S4h-5g
20.K5a-6b
21.P3g-3f
22.K6b-7a
23.P8g-8f
24.P8c-8d?
This might already be an important mistake. It looks like Habu
underestimated the power of the next move.
25.B8h-5e!
A very simple threat (taking the pawn on 6d), but quite hard to defend against. 6c is supposed to be the square for the gold on 4a, so 26.S6c is not a move that white wants to play.
26.P6d-6e
Habu decides to push the attacked pawn, but this creates some serious weaknesses. White has lost the opening battle.
27.S7i-8h
28.G4a-5b
29.S8h-8g
30.R4b-3b
31.P4g-4f
32.S4c-5d
33.B5e-7g
34.P7c-7d
35.R2h-3h
36.P4d-4e?
White is in trouble, but this makes matters worse. Black is also better after 36.B2b P5e S5d-6c S5f S6d P4e Px4e P2d Px2d R2h B3c N3g, but this variation is better for white than the game.
37.P4fx4e
38.R3b-4b
39.R3h-4h
40.B3cx7g+
41.N8ix7g
42.B*3i
43.B*3g!
Already more or less decisive. White can not defend against the attack on the long open diagonal to 9a.
44.B3ix4h+
No choice. Black also threatened to win the bishop with R4i next. This is a position where a bishop is worth much more than a rook.
45.S5gx4h
46.S7b-7c?!
Habu already seems to have lost all fighting spirit. Better was 46.N7c P7e G6c Px7d Gx7d B*4d, but even then the black advantage is overwhelming.
47.P7f-7e
Everything works perfectly for black. Because of the silver on 8g, which looked out of place earlier, this attack is now very strong. The head of the black knight on 7g is defended well enough for this to work.
48.P6e-6f
Tries to complicate things, but...
49.P7ex7d
Tanigawa just ignores white's attempt at counter play and goes straight for the win. Playing Tanigawa in a position like this is like trying to stop a bullet train.
50.P6fx6g+
51.G5hx6g
52.S7c-8b
53.B3gx8b+
Combined with the next black move, white's position is shattered.
54.K7ax8b
55.B*3g
Game over, but Habu decided that 55 moves was a little too short for a title match game.
56.K8b-7b
57.B3gx9a+
58.G6a-6b
59.S*8b!
Tanigawa-style attacking defence. Most players would play 59.N3g here to take the last white chances out of the position. Tanigawa has seen that after 60.Rx4e, he can defend with 61.L*4g which closes of the escape route of the white king, as 62.P*4f fails to Lx4f Rx4f Sx8a=.
60.K7b-6a
61.+B9ax8a
62.R*2h
63.P7d-7c+
64.R2hx4h+
65.P*6h
66.R4bx4e
67.N*6d
68.K6a-5a
69.+P7cx6b
70.G5bx6b
71.S8b-7c=
Resigns
Time: 06:52:00 06:38:00
Habu finally throws the towel. White can not take this silver because of mate in one and after 72.R4g+ Sx6b= K4b G*5h white's position is completely hopeless.
A complete defeat for Habu, who saw a strategical loss after opening quickly deteriorate. Still, all is not lost as the Oi match is now level at 3-3 and a decisive seventh game is needed to decide the winner.
