[Black "Habu Yoshiharu, Meijin"]

[White "Moriuchi Toshiyuki, Challenger"]

[Event "62nd Meijin-sen, Game 1"]

[Date "April 13th and 14th 2004"]

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

2.P3c-3d     00:00:00  00:06:00

3.P2g-2f     00:02:00  00:06:00

4.P5c-5d     00:02:00  00:09:00



This is only the second time that Habu and Moriuchi have 

played this position against each other. The first time 

was in December 2002 in the Osho league. There Moriuchi 

had the black pieces and play continued 5.P2e R5b to end 

up in a Gokigen Nakabisha.



5.S3i-4h     00:16:00  00:09:00



In this game, Habu plays the more defensive 5.S4h, which 

in general leads to less sharp positions than 5.P2e.



6.B2b-3c     00:16:00  00:22:00



This move was first played by Sato Yasumitsu in March 2002, 

in his A class Junisen game against Morishita. The idea behind 

this move is to play Mukaibisha without having to close the bishop 

diagonal. Moriuchi's play is a textbook example of a successful 

implementation of this opening strategy. When the pawn is still on 

4c, white has a number of extra attacking possibilities like S4d 

followed by P5e and P6e. 6.B3c is considered a very strong move. 

Data shows that white has won 17 of the 29 games played with this move.



7.K5i-6h     00:20:00  00:22:00



It looks like black can make a promoted bishop here with 7.Bx3c+ Nx3c 

P2e R2b B*5c, but then B*5e is the perfect answer. Because black has 

played S4h, it is impossible to defend against the invasion on 9i.



8.R8b-2b     00:20:00  00:26:00

9.K6h-7h     00:23:00  00:26:00

10.S3a-4b    00:23:00  00:27:00

11.P5g-5f    00:31:00  00:27:00

12.K5a-6b    00:31:00  00:27:00

13.S4h-5g    00:33:00  00:27:00

14.K6b-7b    00:33:00  00:48:00

15.P6g-6f    00:52:00  00:48:00

16.K7b-8b    00:52:00  01:14:00

17.G4i-5h    00:57:00  01:14:00

18.S4b-5c    00:57:00  01:14:00

19.G5h-6g    01:05:00  01:14:00

20.P7c-7d!   01:05:00  01:41:00



Diagram 1



Well played. It is not normal to play P7d before P6d, as it opens up 

the diagonal to the white king. However, in this case there is an 

important difference in the move order. Black wants to castle as 

quickly as possible, but after 21.B7g, white gets a very strong 

attack after 22.R7b followed by P7e Px7e S6d. 



21.P2f-2e    01:38:00  01:41:00



This binds the rook to defense of the second file, but the pawn on 

2e can become a target for the white attack and the one move delay 

in the building of the black castle is also an important plus for 

white.



22.P6c-6d    01:38:00  02:17:00

23.B8h-7g    01:42:00  02:17:00

24.G4a-5b    01:42:00  02:18:00

25.K7h-8h    01:54:00  02:18:00

26.G5b-6c    01:54:00  02:19:00

27.S7i-7h    02:18:00  02:19:00

28.L9a-9b    02:18:00  03:20:00

29.P8g-8f    03:54:00  03:20:00



The sealed move. Alternatives are P3f or P9f.



30.K8b-9a    03:54:00  03:22:00

31.S7h-8g    03:54:00  03:22:00

32.S7a-8b    03:54:00  03:22:00

33.G6i-7h    03:54:00  03:22:00

34.G6a-7a    03:54:00  03:23:00

35.P3g-3f    03:59:00  03:23:00

36.S5c-4d    03:59:00  03:40:00

37.P4g-4f    04:24:00  03:40:00

38.R2b-5b    04:24:00  04:39:00

39.P9g-9f?   04:40:00  04:39:00



Diagram 2



It is hard to imagine that this is a bad move, but it gives white 

the chance to start the attack. Necessary was 39.N3g to be ready 

for the counter attack.



40.P5d-5e    04:40:00  04:47:00

41.P5fx5e    04:40:00  04:47:00

42.P6d-6e    04:40:00  04:48:00

43.P6fx6e    05:48:00  04:48:00



A rather submissive move. In the press room the more positive 43.P2d 

Px2d N3g was analyzed, but Habu pointed out after the game that Px6f 

Sx6f S5e loses by one move after P*5c Rx5c N4e Sx6f. White dictates 

the pace in this game.



44.S4dx5e    05:48:00  05:00:00

45.P*5f      05:50:00  05:00:00

46.P*6f      05:50:00  05:00:00

47.S5gx6f    05:51:00  05:00:00

48.S5ex5f    05:51:00  05:02:00

49.P*5e      05:52:00  05:02:00

50.S5fx6g+   05:52:00  05:12:00

51.G7hx6g    05:52:00  05:12:00

52.P*6d      05:52:00  05:12:00

53.S*5f      06:02:00  05:12:00

54.P6dx6e    06:02:00  06:04:00

55.S6fx6e    06:07:00  06:04:00



Diagram 3



The normal 55.S5fx6e fails to 56.G*6d R5h N7c and the pressure in the 

center is too much. 55.Sx6e is a desperate attempt to force a 

sennichite and Habu almost succeeds with his little piece of magic.



56.G*6d      06:07:00  06:53:00

57.G6g-6f    06:37:00  06:53:00

58.G6dx6e    06:37:00  06:56:00

59.G6fx6e    06:37:00  06:56:00

60.S*6d      06:37:00  06:59:00

61.G*6f      06:38:00  06:59:00

62.S6dx6e    06:38:00  07:02:00

63.S5fx6e    06:38:00  07:02:00

64.G*6d      06:38:00  07:05:00

65.S*5f      06:39:00  07:05:00

66.G6dx6e    06:39:00  07:06:00

67.G6fx6e    06:39:00  07:06:00

68.S*6d      06:39:00  07:06:00

69.G*6f      06:39:00  07:06:00

70.S6dx6e    06:39:00  07:06:00

71.S5fx6e    06:39:00  07:06:00



Diagram 4



The commentators and the spectators were already looking forward to a 

second game.



72.P*6d!     06:39:00  07:37:00



But Moriuchi wants nothing of it. He has found a hole in the sennichite 

sequence.



73.S6e-5f    06:45:00  07:37:00

74.G*6e      06:45:00  07:37:00

75.S*6g      07:14:00  07:37:00

76.G6ex6f    07:14:00  07:41:00

77.S6gx6f    07:14:00  07:41:00

78.G*6e      07:14:00  07:41:00



Diagram 5



Here it is. White can force a position with the gold on 5f and the silver 

on 6f, which leaves a hole on 6g.



79.G*6g      07:17:00  07:41:00

80.G6ex5f    07:17:00  07:49:00

81.G6gx5f    07:17:00  07:49:00

82.S*4g      07:17:00  07:51:00

83.G*5g      07:39:00  07:51:00



Or 83.G5g P6e Sx6e Rx5e with attack on gold and silver. Black can not take 

this rook with Bx5e, because after Bx5e (check) this bishop can be dropped 

on 3i next.



84.S4gx5f+   07:39:00  07:53:00

85.G5gx5f    07:39:00  07:53:00

86.G*6g      07:39:00  07:53:00

Resigns      07:42:00  07:53:00



Final Diagram



An unexpected resignation. However, black does not have much to play for 

here. If the bishop moves, white breaks through the center and the difference 

in king position is too big. If black gives up the bishop after 87.S7h Gx7g 

Nx7g B1e, he just loses material while the white attack just keeps on going. 

Moriuchi starts his third consecutive match with a win in the opening game. 

A bad loss for Habu with the black pieces. He is already under a lot of 

pressure in this match.
