50th Osho-sen, Game 2, January 18th and 19th 2001
1. P7g-7f 2. P3c-3d 3. P2g-2f 4. P4c-4d 5. P2f-2e 6. B2b-3c 7. S3i-4h 8. R8b-4b
Before the game, Tanigawa said that he would like to try different
openings in this match. Also, Habu has had a lot of problems against
the Shikenbisha in his matches against Fujii. So even though Tanigawa
is far from an Shikenbisha expert, it was not a big surprise that he
chose this opening after he lost the first game in the R8e Yokofudori.
9. K5i-6h 10. S3a-3b 11. K6h-7h 12. S7a-7b
13. P5g-5f
14. P9c-9d
15. P9g-9f
16. K5a-6b
17. G4i-5h
18. S3b-4c
19. P3g-3f
20. K6b-7a
21. S7i-6h
22. K7a-8b
23. S6h-5g
24. G4a-5b
25. S5g-4f
Quick fight again. Maybe Habu regretted a little that he played the
Left Mino in the decisive game of the Ryu-O match...
26. R4b-3b 27. P3f-3e 28. P5c-5d 29. P3ex3d 30. S4cx3d 31. P2e-2d 32. P2cx2d
The sealed move. This is one of those games where you wonder what the
players thought about for a full day. This position has been played
a million times before.
33. R2h-3h
34. P4d-4e
35. B8hx3c+
36. R3bx3c
37. B*6f
38. P*3e
The first really interesting point in the game. The sharpest variation
is 38. Px4f Bx3c+ P*3g Rx3g P*3f +Bx3d (Rx3f S4e is good for white) Px3g+
Nx3g Px4g+ Sx4g R*3i R*4a. This was played in the game between Kimura
and Moriuchi in the Kisei tournament last spring. Moriuchi followed with
G5b-5a and won the game after Rx2a+ S*8h. However, Habu was in the
press room when this game was played and analysed it with Sato
Yasumitsu.
Tanigawa must have figured that they found some improvement for Kimura's
play, so he decided to play 38. P*3e here instead.
39. S4f-5g
40. B*6d
41. P*2b
This looks good for black. However, analysis in the press room and a
postmortem analysis of one and a half hours did not find any way for
black to get a solid advantage from here. If this position is better
for black, the difference is very small.
42. B6dx1i+
43. P2bx2a+
44. R3c-4c
45. R3h-3i
46. L*2f
47. B6fx1a+
48. L2fx2i+
49. R3i-5i
50. P3e-3f
51. N*8f?
A rare mistake in positional judgement by Habu. He was convinced that
his position was worse here and decided to attack. He also seriously
considered 51. L*4d R5c N*6e R2c +P2b R3c +P2a here, which leads to
sennichite. The white rook can not be trapped, but it can also not
escape. In the end Habu decided that a sennichite with black was not
a good result and played 51. N*8f. However, there was a much better move
here to avoid sennichite: 51. +B6f. As the proverb says: "The promoted
rook in the opponent camp, the promoted bishop in your own camp". Then,
if 52. S3e L*9h with a strong edge attack coming up, or 52. N*2f +P3a N3h+
+P3b and black has good chances.
52. S3d-3e
53. N8fx9d
54. K8b-7a!
If 54. Lx9d P9e then white is in trouble, but after 54. K7a the position
has changed in white's favour. Black has to attack this king from both
sides to avoid that the king runs away, but does not have the material
to do so. Despite the white advantage, things are still very much
unclear here.
55. P*3d
56. P3f-3g+
57. S4hx3g
58. +B1ix3g
59. R5ix2i
60. L9ax9d
61. P9f-9e
62. N*6e
63. S5g-6f
64. P4e-4f
65. P3d-3c+
66. R4c-4d
67. +P3c-3d
68. R4dx3d
69. +B1a-1b
70. R3d-4d
71. P4gx4f
72. +B3g-3h
An alternative was 72. P*9h Lx9h P*9g Lx9g N*8e followed by S*7g, but
Tanigawa did not like this variation.
73. R2i-1i
74. L9dx9e
75. L9ix9e
76. P*4g
77. P4f-4e
78. P4g-4h+
79. G5hx4h?
The losing move. This brings the promoted bishop one step closer to the
king and that just means the difference between winning and losing.
Simply taking the rook with 79. Px4d was best. Then 80. +B2h +B3d +Bx1i
P4c+ is still very much unclear. For example, R*9h L*8h N*9f +Bx3e
P*4d S*9g and no one could find a win for white. Habu said after
the game that he thought he was already losing here, while in reality
things were still very difficult.
80. +B3hx4h
81. P4ex4d
82. N*9g
83. R1i-1h
84. P*3h
85. R*4e
86. +B4hx6f
87. P6gx6f
88. N9gx8i+
89. R4ex6e
90. S*8h
91. G6i-6h
92. S3e-4f
93. N*4i
94. S*5i
95. R1hx3h
96. S4f-4g+
Resigns. Time: 07:52:00 07:47:00
White threatens mate with Sx6h+ and black has no defence. Despite a slow
start, this was a very interesting game that was complicated until the
very end. Habu's mistakes in positional judgement are uncharacteristic.
The next game will show if this was just an incident or if Habu is
losing form a little bit.
