38th Kio Match Game 3

[Date "March 10th 2013"]
1.P7g-7f     00:00:00  00:00:00

Actually, a surprise. Goda likes to play the Aigakari opening with 
black, which starts with 1.P2f. The last time he opened a game with 1.P7f 
was more than 10 months earlier. The game now becomes a Yagura opening 
with both players playing their moves without much hesitation.

Diagram 1

It looks like white is weakening his castle by offering this knight for 
exchange, but white aims at using the knight on 8f, which is a famous 
attack to break down the Yagura castle. In the press room, Yagura specialist 
Aono (8-dan) sighed that he really hated this move when it was played 
against him. Goda actually has played this position with black once before 
and with the lance on 1h instead of 1g more than ten times, so he will 
have known what to expect.

47.N2ex3c+   01:30:00  00:45:00
48.G4cx3c!?  01:30:00  00:50:00

This is a rather unusual move. Most of the time white takes with the other 
gold on 3b, to avoid the hanging silver on 5c. However, Watanabe said after 
the game that he didn't like the weakness on the side of the king.

49.S3g-4f    01:47:00  00:50:00

It seems like 49.N*2e is an alternative to continue the attack, but white can 
just take this knight with Sx2e. In this type of position a knight is very 
useful for the white attack.

50.S5c-4b    01:47:00  00:54:00

Diagram 2

White cannot immediately try to break down the Yagura castle because after 
50.N*8f Px8f Sx8f Bx8f Bx8f Rx8f P*8g it is not easy to find a good square 
for the rook to retreat. For example, R8b fails to the fork B*7a. However, 
with the silver out of this fork now, white threatens N*8f, so black can no 
longer play the waiting game.

51.P3f-3e    02:32:00  00:54:00
52.P3dx3e    02:32:00  01:10:00
53.P6f-6e?   02:34:00  01:10:00

This was a change of plan and after the game Goda regretted this, saying it just 
invited the attack. He originally wanted to play 53.N*2e here and after Watanabe 
responded in the post-mortem analysis with 54.G3d, Goda became even more 
disappointed: "If that would have been the response, I would definitely have 
dropped the knight." Goda was worried about 54.S4c instead. Then 55.Nx3c+ Sx3c 
and white has a very solid Silver Yagura, which is known to be harder to break 
down than the normal Yagura. Watanabe admitted that he had never even 
considered 54.S4c. Considering the developments after 53.P6e, Goda's best chance 
was to play 53.N*2e here.

54.N7cx6e    02:34:00  01:14:00
55.S7g-6f    02:34:00  01:14:00
56.P8e-8f    02:34:00  01:31:00
57.P8gx8f    02:34:00  01:31:00

63.P2f-2e    02:43:00  01:31:00
64.S2dx2e    02:43:00  01:31:00

Diagram 3

66.N*9d!     02:43:00  01:33:00

Like so often, Watanabe's special positional judgment is shining brightly 
here. He just gives up the silver on 2e to set up a knight attack against 
the black Yagura. No one in the press room believed that this attack would 
be strong enough, but Watanabe said after the game that even though he thought 
the position was difficult, the difference in move options for the black 
and the white pieces made the white position a little easier to play. It needs 
to be said that even though the professionals in the press room preferred 
Goda's position, Goda himself didn't like his position at all, agreeing with 
Watanabe that white had more than enough compensation for the lost material. 
Another interesting point here is that Watanabe thought he didn't have much 
choice because after 66.S3d Bx6c+ followed by +Bx7d his attack would grind 
to a halt. However, in the press room B*2i (after +Bx6c) was analyzed and 
the conclusion was that this position was far from clear.

Diagram 4

Here it is clear that white has enough compensation for the lost material. 
All the white pieces are placed perfectly for attack, while the black 
attacking pieces on the right are not moving well at all. Watanabe decides 
that it is time to go for the kill.

90.P5d-5e    03:40:00  02:38:00
91.P8gx8f    03:43:00  02:38:00

Or 91.Sx5e Px8g+ Sx8g P*8f S9h B*8g and white wins.

92.N9dx8f    03:43:00  02:38:00
93.S9h-8g    03:44:00  02:38:00

95.K8hx7h    03:44:00  02:38:00
96.G*7i!     03:44:00  02:46:00

The decisive blow. If 97.K8h then Gx8i and white wins easily.

97.K7hx7i    03:45:00  02:46:00
98.R8ex8g+   03:45:00  02:46:00

Diagram 5

99.G*7g      03:51:00  02:46:00

Not much choice. After 99.G*7h the reply 100.B*8h is devastating because 
101.Gx8h is answered by +Rx6g and 101.K6h simply by +R8a.

100.N6ex7g+  03:51:00  02:52:00
101.G6gx7g   03:51:00  02:52:00
102.+R8g-8b  03:51:00  02:52:00

Watanabe has his material back and the black king position is in shambles, 
so he no longer needs to rush his attack.

103.P*8f     03:51:00  02:52:00
104.P7e-7f   03:51:00  02:53:00

110.B5g-7e+  03:56:00  03:06:00
Resigns      03:57:00  03:06:00

Final Diagram

Here Goda had enough. The white threat is P*5h +Bx5h P*5g followed by 
dropping a general on 5h. Also, 111.P*6f can simply be answered by P*5g 
followed by S*5h. On the other hand the black attack is non-existent. Watanabe 
takes a 2-1 lead and now only needs one more win to become only the 8th 
player in shogi history to hold three major titles at the same time. Goda 
has to find a way to bounce back, but that will not be easy with the white 
pieces.
