32nd Kio Match Game 5

[Black "Sato Yasumitsu, Challenger"]
[White "Moriuchi Toshiyuki, Kio"]
[Event "32nd Kio-sen, Game 5"]
[Date "March 28th 2007"]
1.P7g-7f     00:00:00  00:00:00

And the winner is... Sato Yasumitsu! This is only about the Furigoma, but 
data shows how important it was to have the black pieces in the final game. 
The total score in all the Kio match games that have been played is 81-38 
in black's favor (more than 68%!). In this match all games have been won by 
black, but that is not the first time. It also happened in the 7th and the 
18th Kio match. Furthermore, in the 23rd Kio match there was a sennichite 
after which black won the replay, and black won all four games in this match. 
The Kio with its short time limit is perfect for converting a small advantage 
into a win. However, that is not all. Coming into this game, Moriuchi and Sato 
had played 51 official games against each other with Sato winning 26. Almost no 
difference, but a big difference between looking at the difference between black 
and white. The black player has 34 out of the 51 games these two players played 
against each other. Finally, with the black pieces Sato has won six games in a 
row against Moriuchi. Both players were pretending not to care about the pawn 
toss, but I'm sure they both really wanted to play with the black pieces.

6.P9d-9e     00:01:00  00:01:00

A little jab by Moriuchi. He is playing the opening system that Sato has been 
playing a lot recently.

Diagram 1

This is different than the second game, the infamous "Shikenbisha returns". 
There Moriuchi played Rx2b+ and Sato said he was surprised because he only 
thought about 15.P*2c R4b. This is how he plays it in this game.

30.B*3d!?    01:10:00  01:55:00

Diagram 2

Moriuchi drops the bishop to pick up the pawn on 2c that was dropped there 
so early. His conclusion was that after taking the pawn, the edge attack at 
the head of this king with P1d followed by P1e is good. Of course, the fact 
that the king hasn't fully castled yet was a cause for concern, but Moriuchi 
thought that he had to act early. It turned out that the weakness of the king 
is more important than he thought.

31.K7i-8h    01:50:00  01:55:00

Sato decides to wait for the white attack, which seems to show that the white 
opening strategy has been a success.

32.G3bx2c?!  01:50:00  02:04:00

Too eager? This gold becomes another weakness. Sato was worried about 32.P4d 
P4f P4e Px4e Bx4e and then take the pawn with the bishop, while leaving the 
gold on 3b.  This seems to be better.

33.P4g-4f    01:50:00  02:04:00
34.P4c-4d?!  01:50:00  02:31:00

Here Moriuchi suggested that 34.R2b G5h S4b S4g G2d followed by P1d and P1e 
as better.

35.S4h-4g    01:51:00  02:31:00
36.P4d-4e    01:51:00  02:34:00
37.P4fx4e    01:51:00  02:34:00
38.B3dx4e    01:51:00  02:34:00

40.B4e-3d    02:02:00  02:39:00
41.P*4f      02:12:00  02:39:00
42.B3d-5b    02:12:00  02:43:00
43.P3g-3f    02:53:00  02:43:00
44.P3ex3f?!  02:53:00  02:43:00

I don't think Moriuchi saw what was going to hit him, but here 44.P1d was an 
alternative. Then 45.Px3e P1e R3h P2f B*3d and it still seems that black is 
better, although the position is less clear than the game.

45.S4gx3f    02:54:00  02:43:00
46.R4bx4f    02:54:00  02:47:00
47.B*4g!     02:54:00  02:47:00

Diagram 3

This seems a terrible spot to drop the bishop, but Sato has seen that white 
cannot defend against the threat R4h followed by Bx8c+, which gives black a 
rook in hand which is very strong against the white position with many scattered 
pieces. After the game Moriuchi admitted that 47.B*4g was a great move. Sato is 
one of the few professionals who seems to dislike intuition. He says he is 
always searching for the "logical move". If there is a bad looking move, but 
he can't find a way for his opponent to make use of it or defend against the 
threat, he will play it. This is a perfect example of that philosophy.

48.G2c-3d    02:54:00  03:00:00

Moriuchi wins a silver, but it is not enough. This game was played at the Shogi 
Renmei building in Tokyo, so there were a large number of professionals in the 
press room, but "there isn't anyone who wants to play this position with white".

69.P*4g!     03:11:00  03:43:00

Diagram 4

This seals it. The only reasonable move seems to be 70.G4e, but then the knight 
can't join the attack anymore and black can just attack without worrying about 
the king.

70.G4f-3g    03:11:00  03:52:00

The unreasonable move. Playing away from the kings is very painful. According 
to Moriuchi the bigger problem is that the position became very easy to judge. 
The number of moves that black needs to mate and white needs to mate are very 
easily calculated and black can easily make sure that he is one move quicker.

71.P2d-2c+   03:11:00  03:52:00
72.G3g-3h    03:11:00  03:52:00
73.R2i-7i    03:21:00  03:52:00
74.P4h-4i+   03:21:00  03:55:00

This creates the pawn defense P*4a, but that is not enough to slow down the black 
attack.

75.L*5f      03:22:00  03:55:00
76.+B5e-4d   03:22:00  03:55:00
77.+P2cx3c   03:22:00  03:55:00
78.P*4a      03:22:00  03:55:00
79.+R1bx1c   03:27:00  03:55:00
80.P3f-3g+   03:27:00  03:55:00

This allows the defense P*3d to slow down the black dragon, but again this is not 
enough.

81.+R1c-2d   03:30:00  03:55:00
82.P*3d      03:30:00  03:55:00
83.G5h-6h    03:33:00  03:55:00
84.G3h-4h    03:33:00  03:56:00
85.P*3e!     03:34:00  03:56:00

Diagram 5

The deciding move. 86.+Bx3e +Rx3e Px3e Lx5c+ and the white position collapses. 
However, without taking the pawn, white is also clearly one move short.

Final Diagram

There is no mate against the black king and there are multiple mating threats 
against the white king like S*7b or S*8d. There is no way this position can be 
defended, so Moriuchi resigned, giving up the Kio title he had only held for a 
year. From 1991 Habu had won 12 consecutive Kio titles, but the last 5 years 
the Kio has changed hands every year. For Sato it was especially a big game to 
win. He had challenged for five consecutive major titles (a record that probably 
never will be broken), but failed to take the title in each of his previous four 
attempts. In the last game of the shogi season, he finally managed to win another 
title and he now holds two titles for the first time since 2003. The last three 
title matches went to wire, giving him a grand total of 86 games played in a year, 
sharing third place on the all-time list. A very busy year and no wonder Sato said 
after the game that he would take it easy for a little while.
