11th Ryu-O Match Game 2

Black: Fujii, Challenger
White: Tanigawa, Ryu-O
11th Ryu-O-sen, Game 2, October 28th and 29th
1.P7g-7f           0/0          0/0
2.P3c-3d           0/0          3/3
3.P6g-6f           6/6          0/3
4.S3a-4b           0/6          27/30

After long thought on only the fourth move, Tanigawa decides to play
Ai-Furibisha (Double Ranging Rook). The 27 minutes he took to make that
decision are not a sign of great confidence and good opening preparation.
It seems like Tanigawa has no idea how to fight the Fujii system.

5.S7i-6h           23/29        0/30
6.P5c-5d           0/29         13/43
7.S6h-6g           2/31         0/43
8.S4b-5c           0/31         1/44
9.B8h-7g           28/59        0/44
10.R8b-3b          0/59         16/60
11.R2h-8h          2/61         0/60
12.S7a-8b          0/61         10/70
13.P8g-8f          4/65         0/70
14.P7c-7d          0/65         33/103

Preparing for the Yagura castle. In Ai-furibisha games it is not strange to
play the Yagura, since the main attack is coming from the front.

15.P8f-8e          31/96        0/103
16.S8b-7c          0/96         0/103
17.G6i-5h          1/97         0/103
18.P3d-3e          0/97         9/112
19.P4g-4f          4/101        0/112
20.P6c-6d          0/101        10/122
21.G5h-4g          24/125       0/122
22.G6a-7b          0/125        22/144
23.K5i-4h          2/127        0/144
24.K5a-6b          0/127        3/147
25.S3i-3h          17/144       0/147
26.G4a-5b          0/144        5/152
27.K4h-3i          9/153        0/152
28.G5b-6c          0/153        5/157
29.B7g-8f!         21/174       0/157

Diagram 1

Subtle move. This bishop is now in a very good position to attack the Yagura
with P6e. The white counter 29.P6e might be a problem, but Fujii has seen that
the quiet return 30.B7g only helps black, since the game is opened on the head
of the white king.

30.K6b-7a          0/174        72/229

Tanigawa realizes that Fujii is going to get what he want from this position
and takes more than an hour to figure out a way to fight back.

31.N8i-7g          4/178        0/229

Black's position now looks perfect, but things are not that easy...

32.S5c-6b          0/178        7/236
33.P9g-9f          3/181        0/236
34.P1c-1d          0/181        2/238
35.P1g-1f          39/220       0/238
36.K7a-8b          0/220        11/249
37.K3i-2h          2/222        0/249
38.B2b-3c          0/222        34/283
39.R8h-6h          25/247       0/283
40.P2c-2d          0/247        9/292
41.S6g-5f          46/293       0/292
42.L1a-1c!         0/293        11/303

Good move by Tanigawa. The easiest attack for black would have been 43.S4e,
but after having played the lance to 1c, white can retreat the bishop to 1a.
If white would not have played the lance, 43.S4e B2b would be very risky with
2c as a potential point for attacking both rook and bishop. 

43.P6f-6e          70/363       0/303

Diagram 2

This move shows that Fujii is very confident. Despite the fact that white has
built up a strong defensive formation, he decides to start the attack.

44.P6dx6e          0/363        27/330
45.P8e-8d          1/364        0/330
46.P8cx8d          0/364        9/339
47.R6hx6e          2/366        0/339
48.P5d-5e          0/366        5/344

Diagram A

49.R6ex5e!         2/368        0/344

Great move that was overlooked by almost everybody, including Tanigawa. In the
press room only 49.P*6d was analysed, but after 50.G5d S4e Gx6e Nx6e R*8i the
situation is far from clear.

50.P1d-1e??        0/368        33/377

In one  move Tanigawa throws away the game. He must have thought that black had
to take this pawn. Instead 50.B1a R4e P4d R6e P*6d R6i P8e B9g P4e or 50.Bx5e
Sx5e R*8g B*4a Rx8f+ Bx3b+ +Rx7g are both leading to unclear positions with
chances for both black and white.

51.R5e-4e          7/375        0/377
52.B3c-4d          0/375        28/405

After 52.P4d Rx3e Px1f P*1h white has no good move, while black has the easy
attack S5e follwed by P*6d or Sx4d.

53.S5f-5e          32/407       0/405
54.N2a-3c          0/407        11/416
55.R4ex4d          0/407        0/416
56.P4cx4d          0/407        0/416
57.B*4c            0/407        0/416

This variation is similar to the one given before, but black's attack is much
quicker.

58.R*8i            0/407        3/419

Diagram 3

59.P*8c!           11/418       0/419

Fujii plays this game very well. The natural 59.P*6d was analysed in the press
room as being a clear win for black, but Fujii read that 60.R4b Px6c+ Rx4c
+Px7b Kx7b followed by B*6g is not so clear. In this variation the edge attack
suddenly comes alive.

60.K8bx8c          0/418        9/428
61.B4cx3b+         2/420        0/428
62.R8ix8f+         0/420        0/428
63.P*6d            0/420        0/428
64.S7cx6d          0/420        3/431
65.S5ex6d          0/420        0/431
66.G6cx6d          0/420        0/431
67.R*1a!           0/420        0/431

Diagram 4

The deciding move. It looks easy, but it was necessary to calculate that
68.P*5a Rx1c+ followed by +Rx3c was quick enough.

68.+R8fx7g         0/420        5/436
69.R1ax8a+         2/422        0/436
70.S*8b            0/422        0/436
71.N*9e            3/425        0/436
72.K8c-7c          0/425        0/436
73.+R8a-1a         0/425        0/436
74.P9c-9d          0/425        4/440
75.+R1ax1c         0/425        0/440
76.P9dx9e          0/425        0/440
77.+R1cx3c         0/425        0/440
78.P*6c            0/425        1/441
79.L*6e            0/425        0/441
80.P*5c            0/425        6/447
81.L6ex6d          1/426        0/447
82.P6cx6d          0/426        1/448
83.S*4b            5/431        0/448
Resigns            0/431        1/449
Time:              07:11:00     07:29:00

Tanigawa took one minute to make sure that there is no defense and no attack.
The defense 84.N*6a is answered by +B4c G7a N*5d S6c (Px5d +B4d forks king 
and dragon) Sx5c+ Nx5c +Bx5c and black wins. The attack 84.N*5e also does not
help after 85.Sx5c= Sx5c +Rx5c N*6c +B5d Nx4g+ +Bx6d K8c N*7e.

Final diagram

A devastating defeat for Tanigawa. He really needs to come up with something
against Fujii's Shikenbisha fast, or the match will be over very quickly.
