42nd Oi Match Game 1

Black: Yashiki Nobuyuki, Challenger
White: Habu Yoshiharu, Oi
42nd Oi-sen, Game 1, July 17th and 18th 2001
1.P7g-7f     00:01:00  00:00:00

For the first time Yashiki plays a title match where each game 
is played over two days. Furthermore, this first game is played 
in Hokkaido, his native island. How would the challenger deal 
with these two first time experiences?

2.P8c-8d     00:01:00  00:01:00
3.S7i-6h     00:01:00  00:01:00
4.P3c-3d     00:01:00  00:03:00

8.P5c-5d     00:03:00  00:11:00
9.S3i-4h     00:04:00  00:11:00
10.S3a-4b    00:04:00  00:14:00
11.G4i-5h    00:05:00  00:14:00
12.G4a-3b    00:05:00  00:19:00
13.G5h-6g    00:19:00  00:19:00
14.K5a-4a    00:19:00  00:29:00
15.S6h-7g    01:10:00  00:29:00

Habu and Yashiki have never played in a title match before, but 
they have met in other official games ten times. Habu has an 
overwhelming lead, winning eight of them. Habu and Yashiki are 
both all-round players and this clearly shows from the openings 
in their games: 5 times Shikenbisha, 2 times Aigakari, Hineribisha 
once, Yokofudori once and Yagura once. Recently, the Shikenbisha 
is often played in title matches and this was more or less expected 
in this game as well. However, the game started with a Yagura opening. 
The Yagura once was played in almost every title match game, but 
these times are over. It has actually been one year and four months 
since the last Yagura opening appeared in a title match game: the 
3rd game of the 25th Kio match between Habu and Moriuchi.

16.P7c-7d    01:10:00  00:43:00
17.B8h-7i?!  01:21:00  00:43:00

An interesting choice by Yashiki. Pulling this bishop back quickly 
aims at winning a move by making the quick castle K6h-7h-8h followed 
by G7h. Keeping the bishop on 7i then wins black a move. Still, 
this only works if white plays quietly. If not, black runs the 
risk of being blown away by a quick attack. This game is a perfect 
example of this. Commentator Morishita was very surprised by 
Yashiki's opening selection, as black's winning rate is pretty 
bad with this strategy.

18.P6c-6d    01:21:00  01:12:00
19.P3g-3f    01:58:00  01:12:00
20.S6b-6c    01:58:00  01:26:00
21.P3f-3e    02:41:00  01:26:00
22.R8b-5b!   02:41:00  02:15:00

Diagram 1

White ignores the pawn on 3e and goes straight for the king. After 
the game Habu said that he had played this position before and felt 
it was good for white.

23.P3ex3d    03:05:00  02:15:00
24.P5d-5e    03:05:00  02:16:00
25.S4h-5g    03:21:00  02:16:00
26.P5ex5f    03:21:00  02:40:00
27.G6gx5f    03:22:00  02:40:00

This is not the piece with which you want to take this pawn, but 
after the normal 27.Sx5f S5d P4f S5e Sx5e Rx5e P*5f R3e black is 
in deep trouble.

28.N8a-7c    03:22:00  03:13:00
29.G6i-5h    04:11:00  03:13:00
30.S6c-5d    04:11:00  03:31:00
31.G5h-6g    04:22:00  03:31:00
32.P6d-6e    04:22:00  03:43:00

White has won the opening and keeps on attacking.

33.K5i-6i    04:31:00  03:43:00
34.R5b-6b    04:31:00  04:21:00
35.P6fx6e    05:31:00  04:21:00
36.N7cx6e    05:31:00  04:32:00
37.P*6f      05:32:00  04:32:00
38.N6ex5g+   05:32:00  04:34:00
39.G5fx5g    05:33:00  04:34:00
40.P*6e      05:33:00  04:59:00

White has already won a silver for a knight, but Habu is not 
satisfied with this small material gain. He wants black's king.

41.P6fx6e    05:47:00  04:59:00
42.P7d-7e    05:47:00  05:20:00

Diagram 2

43.P7fx7e?   05:57:00  05:20:00

This was already Yashiki's last and only chance to try and make 
a real game of it. 43.G5g-6f Sx6e Gx6e Rx6e P*6f R6d B4f R4d Bx9a+ 
Rx4g+ S*5h and even though white still has the upper hand, the 
undeveloped bishop on 2b makes things a little hard for Habu.

44.R6bx6e    05:57:00  05:33:00
45.G5g-6f    06:02:00  05:33:00
46.R6e-4e    06:02:00  05:48:00
47.B7i-4f    06:07:00  05:48:00
48.R4ex4f    06:07:00  06:21:00
49.P4gx4f    06:07:00  06:21:00
50.P*6e      06:07:00  06:21:00
51.G6f-7f    06:14:00  06:21:00
52.B2b-5e!   06:14:00  06:21:00

Diagram 3

Black seems to have improved his position a little by exchanging 
the bad bishop for the rook, but this strong bishop move ends all 
hope. It has no less than three different meanings: 1) Attack next 
with Bx4f; 2) Defending the lance on 9a, taking the sting out of 
R*8a next; 3) Moving the wall bishop from 2b, so that white's king 
now has an escape route to 2b. Aono's comment: "If a move like that 
is played against you, there is no way to win".

53.R2h-4h    06:37:00  06:21:00

There is nothing for black to play. 53.K7h Bx4f R1h B*4e threatening 
both S*6i and Bx2g+ is even worse.

54.S*6f      06:37:00  06:29:00

Not a very sophisticated move, but very effective.

55.G6g-6h    06:40:00  06:29:00
56.B*5f      06:40:00  06:36:00
57.R*8a      06:51:00  06:36:00
58.P*7a      06:51:00  06:38:00
59.P*6b      07:00:00  06:38:00

Diagram 4

A desperate last attempt by the man known for his "Ninja shogi".

60.B5fx8i+!  07:00:00  06:48:00

Lesser gods might have played 60.G7b?, but then P6a+ followed 
by +Px7a suddenly gives white some hope. However, a holder of 
five major title doesn't play moves like that.

61.P6bx6a+   07:02:00  06:48:00
62.N*5f      07:02:00  06:49:00
63.R8ax7a+   07:05:00  06:49:00
64.S6fx7g+   07:05:00  06:50:00
65.+P6a-6b   07:05:00  06:50:00
66.S*5a      07:05:00  06:50:00
67.+P6bx5a   07:05:00  06:50:00
68.K4a-3a    07:05:00  06:50:00
69.+P5a-5b   07:05:00  06:50:00
70.K3a-2b    07:05:00  06:50:00
71.+P5bx4b   07:05:00  06:50:00

With enormous effort Yashiki has managed to get within one move, 
but Habu has already calculated long before that this is as far 
as white will get.

72.+S7gx6h   07:05:00  06:50:00
73.R4hx6h    07:05:00  06:50:00
74.N5fx6h+   07:05:00  06:50:00
75.K6ix6h    07:05:00  06:50:00
76.R*3h      07:05:00  06:50:00
Resigns      07:05:00  06:50:00

Final Diagram

Simple mate after both 77.K5g G*5f and 77.P*5h G*6g K5i Gx5h. 
A terrible game for Yashiki, being blown away with black in 
front of his home crowd. Will he be able to bounce back in 
game 2 or will this Oi match become a one-sided Habu show?
