41st Oi-sen, Game 2, July 26th and 27th 2000
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.P9c-9d
9.P9g-9f
10.R8b-4b
Habu and Tanigawa are playing a double title match (Kisei and Oi), so they are seeing a lot of each other. It must be hard to come up with a new opening idea every time if you have almost no time to prepare between two games against the same opponent. This time Habu plays Shikenbisha. This game will now have a similar development to game 1 of the Kisei match, but there Tanigawa
played with the white pieces.
11.K5i-6h
12.S7a-7b
13.K6h-7h
14.S3a-3b
15.P5g-5f
16.S3b-4c
17.G4i-5h
18.P6c-6d
19.S4h-5g
20.K5a-6b
21.P3g-3f
22.K6b-7a
23.P8g-8f
24.G4a-5b
25.K7h-8g
26.P7c-7d
27.S7i-7h
28.P8c-8d
29.R2h-3h
30.R4b-3b
31.P6g-6f
32.K7a-8b
33.G5h-6g
34.G5b-6c
35.S5g-6h
36.B3c-5a
37.P4g-4f
38.L1a-1b
39.K8g-9h
40.S4c-5d
41.S7h-8g
42.P4d-4e?!
Habu prepared this attack, timing it just when the black gold on 6i is undefended. However, the general opinion in the press room was that this attack was an overplay and after the game Habu agreed.
43.P5f-5e!
Not 43.Px4e R4b R4h Rx4e and white gets the advantage.
44.S5dx5e
45.P4fx4e
46.P*4f
47.G6i-5h
Black's position looks to be in ruins, but the threat of killing the silver with P*5f is big. White has to fight with everything he has to avoid a simple loss of material.
48.P9d-9e
49.P9fx9e
50.R3b-4b
51.N2i-3g
52.P3d-3e?
Perhaps already the decisive mistake. This pawn sacrifice looks like a normal tesuji, attacking the head of the knight. However, as the game develops, this attack turns out to have no significance. 52.P3e only gives black an extra pawn which will be very important later on. White should have played 52.P8e
immediately. Then, after 53.Px8e Bx9e P*9f Bx6h+ G6gx6h S5f R4h P4g+ Gx4g S*5i R5h Sx6h+ Rx5f P*8f Sx8f G*7h white has a reasonable looking attack for the sacrificed material.
53.P3fx3e
54.P8d-8e
An alternative is 54.Lx9e, but after 55.P*9f P*3f P*5f Px3g+ Rx3g Rx4e Px5e B1e R5g Rx3e but even though white has managed to develop his major pieces, the material loss is more significant.
55.P6f-6e
56.P5c-5d
57.P*5f
58.P8ex8f?
Here Habu misses his last chance to keep the fight interesting. He had planned 58.Bx9e, but did not like the position after 59.P*9f Px8f Px9e Px8g+ Kx8g S*4i R4h Sx5h+ Rx5h P4g+ R1h P*8f Kx8f P*8e K7g +Px3g Px5e Rx4e P*8c. White would like to take this pawn with the silver, but Sx8c fails to B*3d. After Kx8c P*8d K7c Habu did not think he could win. However, this line is superior to the game variation.
59.S8gx8f
60.B5ax9e
61.S8fx9e
62.L9ax9e
63.P*9f
64.L9ex9f
65.P*9g
66.P*8f
67.P*8g!
There it is. The extra pawn that Habu gave Tanigawa on move 52 is now coming back to haunt him. This drop where the opponent wants to drop completely kills Habu's attack.
68.P8fx8g+?
Better would have been 68.P*3f Px5e S*7h Px8f P*8g B7g Px3g+ Rx3g Rx4e and white at least has some play for the lost material.
69.K9hx8g
70.P*8f
71.K8gx8f
72.P*8e
73.K8f-7g
74.S*4i
75.R3h-4h
76.S4ix5h+
77.R4hx5h
78.P4f-4g+
79.R5h-1h
80.+P4gx3g
81.P9gx9f
82.G6c-7c
83.N8i-9g!
Tanigawa does not waste any time. He uses this defensive knight for a strong attack.
84.G7c-8d
No choice, but this has a nasty side effect.
85.P5fx5e
86.R4bx4e
87.P*4f
88.R4ex5e
Because of the gold on 8d, white can not play Rx4f as B*5g would be too severe.
89.G6g-6f
90.R5ex3e
91.B*5c
92.R3e-3c
93.B5cx6d+
94.S7b-7c
95.+B6dx5d
96.+P3g-2h
97.N9gx8e
98.P*8f
Or 98.Gx8e S*9d and black wins quickly.
99.N8ex7c+
100.N8ax7c
101.S*9e
102.R3c-3g+
103.P*5g
104.+P2hx1h
105.S*9c!
Tanigawa is showing off his fabulous endgame skills. Of course, 105.Sx8d would have been more than enough to win.
106.K8bx9c
Habu chooses the long mate over the hopeless 106.K7a S9ex8d.
107.S9ex8d
108.K9cx8d
109.S*7e
Resigns
Time: 07:45:00 07:54:00
Mate after 110.K9c L*9d K8b G*8a K8c Sx7d Kx7d G7e K8c P*8d. Great game by Tanigawa, who made the brilliant Habu look like an average player. Habu's early attack was ill-advised, but Tanigawa needed perfect play to show this. This Oi title match might take a long time to finish...
