1.P7g-7f 00:00:00 00:00:00
2.P3c-3d 00:00:00 00:02:00
3.P2g-2f 00:02:00 00:02:00
4.G4a-3b 00:02:00 00:09:00
An invitation to play the Kakugawari with one tempo loss. Tanigawa
intended to play this opening if black would play 5.P2e. After this,
6.Bx8h+ Sx8h S2b leads to the Kakugawari where white keeps back the
rook pawn.
5.G6i-7h 00:07:00 00:09:00
6.P5c-5d 00:07:00 00:43:00
Upon seeing 5.G7h, Tanigawa changed his mind. He is going for a
Nakabisha opening instead. With the gold on 7h, black can not move
easily into the boat castle with K6h and K7h, and Tanigawa felt that
the black options were already limited enough to switch to another
opening than he originally intended.

33.B8h-7g 02:56:00 02:49:00
34.S3a-4b 02:56:00 03:05:00
35.K7i-8h 03:04:00 03:05:00
36.S4b-5c? 03:04:00 03:21:00
A mistake. Correct was 36.P1d, after which the game continues in quiet
fashion after 37.G5h S5c S6g S5d.
37.R2h-3h! 03:27:00 03:21:00
This attack does not work if white had played 36.P1d, because then
38.B1c is possible. The game is suddenly picking up pace and white
is already stretched a little.
38.P1c-1d 03:27:00 03:47:00
39.P3g-3f 03:53:00 03:47:00
The sealed move.
40.P3ex3f? 03:53:00 03:59:00
Here Habu was worried about 40.B1c. For example, 41.Px3e Rx3e S3f R3c
P*3e S4d N3g G4b N4e R3b and even though black has developed the knight
to 4e, this position is unclear. Habu did not have much confidence in
the black position in this variation. Goda commented that Tanigawa usually
has a perfect balance between intuition and calculation, but that he
relied a bit too much on intuition in this phase of the game. On the
other hand, Habu is often calculating a lot of moves, even strange looking
ones and in this game this turns out to be the better strategy.
41.S4gx3f 03:54:00 03:59:00
42.B2b-1c 03:54:00 04:01:00
43.P*3e 04:11:00 04:01:00
44.R3d-7d 04:11:00 04:03:00
45.S6h-6g 04:14:00 04:03:00
46.P*3d 04:14:00 04:11:00
47.G4i-4h 04:52:00 04:11:00
48.P3dx3e 04:52:00 04:45:00
49.S3fx3e 05:02:00 04:45:00
50.P*3d 05:02:00 04:45:00
51.B7g-8f 05:06:00 04:45:00
52.B1cx3e?! 05:06:00 05:08:00
This move was also criticized by Goda, who suggested 52.S6b instead. Interesting
is that both players thought about different moves after 52.S6b. Tanigawa
looked at the straightforward 53.Sx3e, while Habu preferred the more indirect
53.S2f. Different styles of play showing.
53.R3hx3e 05:06:00 05:08:00
54.P3dx3e 05:06:00 05:08:00
55.B8fx5c+ 05:06:00 05:08:00
56.R*2h? 05:06:00 05:08:00
The losing move, but of the people following this game, only Habu figured out
why this move is a vital mistake. Tanigawa deeply regretted this rook drop and
after the game pointed out that 56.P5f was the only move here. After 57.Px5f
white can play 58.R2h (the reason will become clear soon), but after 57.S*5b
S*6b Sx6a+ Sx6a B*5b S*7b Bx6a+ Sx6a S*5b Sx5c Sx6a= black still has the upper
hand: R*2h S*7a K9c S7b+ is winning and R*7a G*7b Rx7b Sx7b+ Kx7b R*5b is also
good for black. White has no good defense with only major pieces to drop.
57.S*6b! 05:55:00 05:08:00
58.G6ax6b 05:55:00 05:29:00
59.+B5cx6b 05:55:00 05:29:00
60.S*7a 05:55:00 05:29:00
61.+B6bx7a 05:56:00 05:29:00
62.K8bx7a 05:56:00 05:29:00
63.G*3i! 05:56:00 05:29:00
The point. Habu has weakened the defense around the white king and now aims at
getting a rook in hand.
64.R2h-2f+ 05:56:00 05:43:00
65.G4h-3g 05:56:00 05:43:00
66.+R2fx2e 05:56:00 05:45:00
67.B*4g 05:56:00 05:45:00
The difference. If white would have played 56.P5f instead of 56.R*2h, this bishop
fork would not have been possible.
68.P3e-3f 05:56:00 05:45:00
69.G3gx3f 05:56:00 05:45:00

86.B2bx4d 06:38:00 07:19:00
87.B2e-4c+ 06:38:00 07:19:00
Resigns 06:38:00 07:20:00
Only 16:50 in the afternoon, but Tanigawa has nothing but to resign. There is no
good square for the attacked bishop on 4d. 87.B2f fails to R*3f G*3e +B4d, 87.B3e
to R*3d and 87.B6b to S*5c. Another complete victory for Habu, who suddenly is
in control of this match. Quite a different pattern from the previous two Oi matches
between these players, when Tanigawa started by winning the first three games.
Game 4 is now very important. Can Habu take a 3-1 lead or can Tanigawa change the
flow of the match by tying it at 2-2?
