11.S8hx7g          0/14         0/20

The Kakugawari (Bishop Exchange) opening comes as no surprise. In recent
years Tanigawa has become one of the leading experts in this opening. The
question was: what would Sato play against it?

12.S3a-4b          0/14         0/20
13.S3i-3h          7/21         0/20

23.P6g-6f          30/113       0/118
24.S8c-8d          0/113        1/119
25.G4i-5h          31/144       0/119
26.P9d-9e          0/144        67/186

Diagram 1

Sato chooses the aggresive Climbing Silver edge attack. One would think he
played this to force Tanigawa, who is famous for his attack, in a defending
position. However, this is not how it works out.

27.P9fx9e          22/166       0/186
28.S8dx9e          0/166        0/186
29.L9ix9e          0/166        0/186
30.L9ax9e          0/166        0/186
31.P*9g            3/169        0/186
32.S3c-4d          0/169        24/210

This is not a very convincing looking move. Still, it was often played by
Moriuchi, 8-dan, and can therefore not be discarded so lightly. Sato has
studied this position well and decided to give it a try. Still, this silver
move gives black the possibility to set up his own attack.

33.P2f-2e          49/218       0/210

Diagram 2

A Tanigawa-like move. Since this opens up the diagonal to the king, it is
not a move that can be played easily. However, after the safer 33.P1f P*9h
S8h L*9a there is no attack for black. The text move makes a counter attack
much easier.

34.P*9h            0/218        62/272

Played after long thought. Sato probably underestimated the strength of
P2e in his preparation.

35.S7g-8h          1/219        0/272
36.P8e-8f          0/219        2/274
37.P8gx8f          14/233       0/274
38.R8bx8f          0/233        3/277
39.S8h-8g          16/249       0/277
40.R8f-8b          0/249        78/355
41.S8gx9h          30/279       0/355
42.P*8h            0/279        8/363
43.P*8c            5/284        0/363
44.R8b-6b          0/284        2/365

White can not take the pawn because of B*9d.

45.G7hx8h          73/357       0/365
46.L*8d            0/357        3/368
47.S9h-8g?!        0/357        0/368

Better is the simple 47.G7h Lx8i+ Sx8i Lx9g+ K4h and black has a small, but
clear advantage. For example, after R9b to bring the rook into play, black
can play the tesuji P*9c. After Nx9c the rook is again blocked and after
Rx9c black plays P8b+.

48.B*9i            0/357        29/397
49.G8h-9h          4/361        0/397
50.B9ix6f+         0/361        0/397
51.P2e-2d          2/363        0/397
52.P2cx2d          0/363        1/398
53.R2hx2d          0/363        0/398
54.P*2c            0/363        5/403
55.R2d-2e          0/363        0/403
56.R6b-9b          0/363        31/434
57.K5i-4h          4/367        0/434
58.N2a-3c          0/367        7/441
59.R2e-2h          29/396       0/441
60.P*8f            0/396        8/449
61.S8g-9f!         15/411       0/449

Diagram 3

Very strange looking move, but it is the only one in this position. After
61.S7h (which Tanigawa had originally planned) white can play 62.+Bx7f P4e
Nx4e P*4f +Bx9h Px4e S3c and the position is unclear. Tanigawa's move is
keeping the small advantage he got from the opening.

62.L9ex9f          0/411        6/455
63.P*6d!           0/411        0/455

This combination of S9f and P*6d shows Tanigawa's power to attack from
any position.

64.P6cx6d          0/411        7/462
65.B*6c            0/411        0/462
66.P8f-8g+         0/411        9/471
67.B6cx8a+         2/413        0/471
68.R9b-9e          0/413        3/474
69.+B8a-6c         6/419        0/474
70.+P8gx9h         0/419        2/476
71.P9gx9f          2/421        0/476
72.R9e-6e          0/421        5/481
73.L*6h            10/431       0/481
74.S*6b            0/431        38/519
75.N8i-7g?!        14/445       0/519

A mistake that almost loses the game. The simple 75.Lx6f Rx6f +Bx6b Gx6b
S*6g R6e N7g (diagram) is much easier to win for black.

Diagram B

76.R6e-2e!         0/445        0/519

Great effort to turn things around.

77.P*2f!           21/466       0/519

The 21 minutes Tanigawa took for this move prove that he was surprised.
Fortunately, his position is still good enough to have a way out. It seems
like it is very dangerous for white to give up the rook in this position, but
after 77.Rx2e Nx2e R*4a K3c it is surprisingly hard to mate the white king.
Tanigawa is lucky here that the patient but slow move P*2f still wins.

Time:              08:45:00     08:59:00

White can not continue his attack and has no defence against black's attack.
A good start for Tanigawa in pursuit of his sixth Meijin title.
