49th Oi Match Game 4

[Black "Fukaura Koichi, Oi"]
[White "Habu Yoshiharu, Challenger"]
[Event "49th Oi-sen, Game 4"]
[Date "August 6th and 7th 2008"]
1.P7g-7f     00:00:00  00:00:00

This game was played in the city of Sasebo in Nagasaki Prefecture on the southern 
island of Kyushu. It is not often that games are played so far south, but also 
not exceptional. The thing that makes this location special is that it is Fukaura's 
hometown. Playing a title match here must be very special for him and also for the 
local fans. If there was someone around hoping that Habu would win, I am sure that 
he or she was very quiet about it. Actually, this is not the first time Fukaura 
played an important game in Sasebo. In 2004, the first game of the Asahi Open 
Tournament was also played in the same hotel in Sasebo. Fukaura was then the 
titleholder and he faced the same challenger as in the Oi match here: Habu. Four 
years ago it was a great fight, but Habu managed to hang on to a middle game lead 
and win a difficult endgame, much to the disappointment of the local fans. In the 
end, Fukaura lost the match 3-2 so in a way this first game in Sasebo could be 
called decisive. The situation this time is a little better for Fukuara as he 
takes a 2-1 lead into this game, but losing again in Sasebo is something that 
he desperately wants to avoid.

22.R8b-4b    01:09:00  01:04:00

Fukaura has chosen the early silver attack against Habu's Kakugawari with tempo 
loss opening. In response, Habu decides to build a defensive Furibisha position 
with 22.R4b. With this, he can stop the white attack, but it also means that he 
has to wait for an opportunity to attack himself, because there is no natural way 
to open the game with white from here.

38.K6b-7b    03:11:00  03:22:00

Here Habu had to make a very difficult decision. If he allows the black king to 
enter the castle with K8h, the black position will be very difficult to attack, 
white the white pieces are still all over the place. In such a position, black 
can take some extra risks opening the game and it is very unlikely that white 
can win in the counter attack. Therefore, white has to attack but the question 
is whether this attack should be played now or if white should wait one move. 
Specifically, is the position K6i versus K6b better for white than K7i versus 
K7b if the position is opened up. After 70 minutes, Habu decides to wait one move, 
but it is unclear if this is the right decision. Playing 38.P4f directly is also 
a good candidate. If then 39.Px4f Sx4f P*4c Rx4c B*3b R4b Bx2a+ Sx5g+ P*4c R5b N*4d! 
R5a +B3b S*2g (if Rx2g B*3f) and the position seems unclear.

39.K6i-7i    03:14:00  03:22:00
40.P4e-4f    03:14:00  03:24:00

Diagram 2

43.P*4c      04:14:00  03:25:00

After 43.Sx4f Rx4f white has everything he wanted with the exchange of the silver 
and the activation of the rook.

44.R4bx4c    04:14:00  03:29:00
45.B*3b      04:14:00  03:29:00
46.R4c-4b    04:14:00  03:29:00
47.B3bx2c+   04:14:00  03:29:00

This time black has no choice. 47.Bx2a+ Sx5g+ P*4c fails to R6b and black no longer 
has N*4d like in the variation with the white king still on 6b. By the way, because 
the black king is on 7i here, white doesn't have S*2g because after R*2g the drop 
B*3f is not a check. Waiting one move changes everything.

48.S4fx5g+   04:14:00  03:30:00
49.P*4d!     04:14:00  03:30:00

A strong pawn drop. This draws the rook out and black even manages to exchange his 
bad rook now. Black has the advantage here and slowly extends the lead.

69.S*9b?!    05:42:00  05:57:00

If this would have really worked, it would have become a famous "devilish" move to 
decide the game. Actually, after this move was played, it was expected that the 
game would end soon. It looks very good, because after 70.Lx9b R*9a K8b +Bx8c is 
winning. Also, after 70.Lx9b R*9a +B4f +Bx4f K8b black has the strong +B5g and 
after Rx2i+ +Bx9c wins. However, Habu next shows that things are a little more 
complicated than that. If Fukaura would have seen this, he probably would have 
played 69.R*2b R3a+ R2f+ instead. This is much slower, but black's promoted rook 
and bishop are working well and it is very hard for white to get anything going 
against the black position.

70.L9ax9b    05:42:00  06:10:00
71.R*9a      05:42:00  06:10:00
72.+B1ix2i   05:42:00  06:15:00
73.R9ax9b+   05:42:00  06:15:00
74.L*8b      05:42:00  06:15:00
75.+B4gx2i   05:57:00  06:15:00
76.R3ix2i+   05:57:00  06:15:00

Now things are not so easy anymore, because black has given white a lot of pieces 
in hand. In the press room some people even dared to suggest that Habu had turned 
the tables here. The question was: how to tell this to all the Fukaura fans in the 
commentary room?

77.K7i-8h    05:57:00  06:15:00
78.+R2i-2h   05:57:00  07:09:00

Diagram 4

79.B*4g!     06:16:00  07:09:00

Fukaura still believes in his position. This doesn't look like a very impressive 
move (it threatens Bx8c+, but this is easily blocked), but in combination with 
his next move, this is very strong.

80.N*6e      06:16:00  07:19:00
81.L*2i!     06:18:00  07:19:00

The real point of 79.B*4g. Black would very much like to use this lance on 8f to 
put pressure on the 8th file, but that doesn't really work here. In this position 
Habu is a knight up and there is no direct attack for both players. Fukaura therefore 
decides to go for material which is the right decision here. This lance picks up both 
the knight on 2a and the lance on 1a, which gives the material advantage to Fukaura. 
His deep understanding of how the balance of this game has shifted from attacking 
(69.S*9b) to material has to be admired. 

82.+R2h-1h   06:18:00  07:44:00

The alternative 82.+R1g looks better because it attacks the bishop on 4g, but after 
83.Bx6e Px6e Lx2a+ the promoted rook on 1g is no longer a threat to the black king, 
while the white position is very vulnerable to knight drops (for example on 7e).

83.L2ix2a+   06:19:00  07:44:00
84.B*4f      06:19:00  07:45:00

87.S7g-6f    06:35:00  07:50:00

90.G6a-7a    06:35:00  07:52:00
91.N*5e      07:01:00  07:52:00
92.S6c-5d    07:01:00  07:52:00
93.G*5f      07:01:00  07:52:00
94.B4f-1i+   07:01:00  07:53:00
95.L*8f      07:05:00  07:53:00
96.K7b-6a    07:05:00  07:53:00

Diagram 5

This early escape seems to have made L*8f a useless move, but Fukaura has calculated 
this deeply.

97.S6fx6e    07:09:00  07:53:00
98.P6dx6e?   07:09:00  07:55:00

White's last chance was 98.Sx5e and after 99.Gx5e +Bx5e S*6f +Bx1a Sx7d white has 
the strong P6e and S7g is answered by P*7e. This variation was found after analyzing 
the position for a long time in the post-mortem analysis and both players agreed 
that white may have the better position here.

99.N*6d      07:09:00  07:55:00

A vulgar move, but a strong one because 100.Sx5e fails to Lx8c+. 

100.S*9d     07:09:00  07:55:00
101.N6dx5b+  07:10:00  07:55:00
102.K6ax5b   07:10:00  07:55:00
103.S*7b     07:11:00  07:55:00

This looks slow, but is unexpectedly fast.

104.S5dx5e   07:11:00  07:55:00
105.S7bx7a=  07:13:00  07:55:00
106.S5ex5f   07:13:00  07:55:00
107.B4gx5f   07:13:00  07:55:00
108.+B1i-5e  07:13:00  07:55:00

A fork on king and promoted bishop, but black has nothing to fear.

109.K8h-9h   07:13:00  07:55:00
110.N*9e     07:13:00  07:55:00

After 110.+Bx5f S*4d the black attack cannot be stopped. Also, 110.S*6i is not a 
mating threat, so black can simply play B3d and again white cannot properly defend.

111.B5f-3d   07:23:00  07:55:00
112.S*4c     07:23:00  07:56:00

Final Diagram

Mate after 124.K5a (or K5b) G*6b, 124.K3a (or K3b) G*4b K2b +L1b or 124.P*4b Lx4b+ 
Kx4b S*4c etc. Fukaura answers the hopes of all his fans and wins in Sasebo. This 
will make him very happy, but he will be even more satisfied with the score line. 
He takes a 3-1 lead and only needs one more win to defend his Oi title for the first 
time. Of course, the situation is the same as last year and then Habu managed to win 
game 5 and 6 to take the match to an all-deciding seventh game. Fukaura knows that 
needing only one more win is no guarantee against Habu...
