34th Kio Match Game 4

[Black "Kubo Toshiaki, Challenger"]

1.P7g-7f     00:00:00  00:00:00

Quite a lot of professional players were watching this game this time, because 
it was played in the Kansai Shogi Renmei building in Osaka. Title matches are 
regularly played in the Renmei headquarters in Tokyo, but playing in Osaka is 
quite rare. The last time a title match game was played there was in 1993, when 
Habu and Tanigawa played a game from the 18th Kio title match there. Interestingly, 
this game was played in the same room where Sato and Kubo played their 8th round 
game of the A class Junisen last February. That was also a must-win game for 
Sato, because losing it would have meant relegation to the B1 class. Sato won 
that game and saved his spot in the top class, while Kubo was later relegated 
to B1. Although Kubo is from the Kansai area and would have a lot of support 
for this game, Sato will have been happy to play where he had good memories 
while his opponent had some bad ones.

In this do-or-die game, Sato plays the quick attacking variation of the 
climbing silver. Kubo is meeting this head-on, but...

41.B9e-7g?   02:02:00  01:15:00

This was considered a mistake by the professionals following this game, maybe 
even the losing move. Kubo seems to have been overdoing it already, but here 
the only way to try and stay in the game was 41.B5i. Then 42.Rx7e Px7e Bx9i+ 
is forced. After this, black should not play B7g, because +Bx8i Bx1a+ S*2b is 
good for white, but after simply P7d +Bx8i R7e N*6f B*7g is a good counter. 
Still, the static rook side seems to have the advantage, but this is much 
less clear than in the game.

70.R8f-8i+   02:40:00  02:04:00

It has taken white a while, but black couldn't really avoid this breakthrough. 
Now the white advantage is clear, but black has a promoted bishop that works 
well in defense. Kubo is not prepared to throw the towel yet and is digging 
in, hoping for a chance to turn the tables.

71.R7h-5h    02:40:00  02:04:00
72.+R8ix9i   02:40:00  02:04:00

74.P5dx5e!   02:48:00  02:08:00

Diagram 2

Well judged. This looks dangerous, because it seems that black can play a 
dangling pawn with P*5d followed by the knight jump to 6e. However, Sato 
has seen that 75.P*5d can be answered strongly with 76.L*5f and the white 
attack is stronger. By playing 74.Px5e, Sato gets an important extra pawn 
in hand which gives him the strong attacking option of P*8f followed by an 
attack on the head of the knight with P7e.

75.+B3f-4g   02:59:00  02:08:00

The only thing that Kubo can do is strengthen his defense and hope for the 
best.

77.P*8h      03:00:00  02:13:00

84.+R9ix9f!  03:18:00  03:04:00

Diagram 3

Difficult move to play, because this rook seems to be moving away from the 
action. However, getting a knight in hand will make the white attack 
unstoppable as we will see. The only way black can save this knight is 
by playing 85.+B7d but this puts the defending bishop out of play, so 
black can attack strongly with 86.+R9g.

85.P*9b      03:23:00  03:04:00
86.P8f-8g+   03:23:00  03:05:00

91.P*6h      03:24:00  03:05:00
92.S*5f!     03:24:00  03:16:00

Diagram 4

This decides the game, even though there are still many moves played. White 
exchanges the promoted rook for the defending bishop and with that the white 
attack becomes unstoppable. From now on, Sato gives a clinic in how to play 
threat after threat, forcing black into desperate but hopeless defensive 
moves.

Final Diagram

The mate is very simple after 143.K3g (or K2g) G*2f K3h +P4h. For the second 
time in a row, Sato plays an almost perfect game with his back against the 
wall. Maybe it is just that the resolution to play positively that gave him 
a 2-0 lead now backfires on Kubo, but the pressure is now on him. Kubo is a 
very gifted player, but there have been a number of occasions where the pressure 
has been getting to him on the biggest stage. We only need to go back to the 
fifth game of last year's Osho match against Habu where he lost a game he was 
winning by playing the king to the wrong square. He has been saying in 
interviews that he has grown mentally lately and in the final game of this 
Kio match we will see whether or not he was just saying that to convince himself.
