In this Shukan Shogi report the third game of the Meijin match between
Moriuchi and Habu. Here is the game with comments:
[Black "Moriuchi Toshiyuki, Meijin"]
[White "Habu Yoshiharu, Challenger"]
[Event "70th Meijin-sen, Game 3"]
[Date "May 8th and 9th 2012"]
1.P7g-7f 00:00:00 00:00:00

12.G4a-3b 00:10:00 00:12:00
13.G6i-7h 00:10:00 00:12:00
14.K5a-4a 00:10:00 00:13:00
15.K5i-6i 00:10:00 00:13:00
16.P7c-7d 00:10:00 00:15:00
17.G5h-6g 00:11:00 00:15:00
18.S6b-5c 00:11:00 00:17:00
In this game Habu uses a quick attacking plan against Moriuchi's Yagura
formation.
19.P2g-2f 00:18:00 00:17:00
20.P8d-8e 00:18:00 00:20:00
21.S6h-7g 00:29:00 00:20:00
22.P5d-5e 00:29:00 00:22:00
23.P5fx5e 00:31:00 00:22:00
24.B2bx5e 00:31:00 00:22:00
25.B8h-7i 00:44:00 00:22:00
26.B5e-7c 00:44:00 00:27:00
27.B7i-4f 00:45:00 00:27:00
28.S5c-6d 00:45:00 00:27:00
29.P7f-7e 00:51:00 00:27:00
This is the standard move to attack the head of the bishop after it has
moved to the other side of the board.
30.R8b-8d 00:51:00 00:38:00
31.P7ex7d 01:01:00 00:38:00
32.R8dx7d 01:01:00 00:39:00
33.P*5f 01:02:00 00:39:00
34.K4a-3a 01:02:00 01:01:00
35.P2f-2e 01:10:00 01:01:00
36.G6a-5a 01:10:00 01:14:00
37.P*7f! 01:40:00 01:14:00
This is a new move by Moriuchi and an improvement. In the famous Ryu-O
match in 2008, where Watanabe overcome a 3-0 deficit to keep his title
against Habu, the 6th game proceeded with 37.P2d Px2d Bx2d to exchange
the pawn in front of the rook, but Watanabe strongly countered with B6b
P3f P*2g Rx2g P*2f R2h Rx7g+ G6gx7g S*2g and won the game. Moriuchi
closes the rook line first and now P2d is a real threat.
38.S4b-3c?! 01:40:00 02:21:00
This defends against the pawn exchange on the second file, but it is
also very risky because the gold on 5i is now no longer connected to the
castle formation. If white would get the time to play G5a-4b, his
position would be alright, but...
39.P6f-6e 02:12:00 02:21:00
Moriuchi sees the hanging gold on 5a and immediately starts attacking.
40.S6dx6e 02:12:00 02:43:00
41.B4fx7c+ 02:14:00 02:43:00
42.N8ax7c 02:14:00 02:43:00
43.B*8b 02:19:00 02:43:00
If white doesn't do anything, black will just get a lance in hand and
promote the bishop at the same time.
44.P8e-8f 02:19:00 02:54:00
45.P8gx8f 03:11:00 02:54:00
46.P*8h 03:11:00 04:12:00
47.G7hx8h 03:50:00 04:12:00
The sealed move.
48.B*4i? 03:50:00 04:14:00
Now white gets into serious trouble. The best way to keep the game close
is 48.P*8e. Then 49.Px8e Nx8e just invites another piece into the attack
so black must play 49.Bx9a+ 50.Px8f, but then there are a number of
alternatives, none of which seem to give black a clear advantage. For
example, 51.P7e Rx7e Sx8f S7f G6h R6e P*6f Rx6f S7g Rx6h+ Sx6h P*5g or
51.L*7e R5d P5e Rx5e +Bx7c B*5h K6h Bx6g+ Kx6g S5f K5h or 51.P*6f P8g+
Gx8g Sx5f Gx5f B*6g S5g Bx8i+ were variations that were analyzed in the
press room and the post-mortem analysis, but no conclusion was reached
in any of them. Habu admitted after the game that he should have played
48.P*8e here.
49.P*6h 04:11:00 04:14:00
50.K3a-2b 04:11:00 04:20:00
Very unnatural to give up the initiative after the very aggressive
48.B*4i, but it is too risky to go all out attack, most likely giving up
a bishop in the process. This bishop would come back to hunt white with
B*5c or B*7e as long as the king is on 3a.
51.B8bx9a+ 04:25:00 04:20:00
52.G5a-4b 04:25:00 04:24:00
53.L*5h! 04:59:00 04:24:00
Very strong defensive move that forced Habu into additional material
sacrifice.
54.S6ex7f 04:59:00 05:11:00
This sacrifices an inordinate amount of material, but the alternative
54.P*7e K5i Px7f Kx4i Px7g+ G7g-6g S6f P*7f seems to stop the white attack.
55.G6gx7f 05:16:00 05:11:00
56.R7dx7f 05:16:00 05:11:00
57.S7gx7f 05:16:00 05:11:00
58.P*8g 05:16:00 05:11:00
59.G8hx8g 05:45:00 05:11:00
60.G*2g 05:45:00 05:11:00
61.R2hx2g 05:52:00 05:11:00
62.B4ix2g+ 05:52:00 05:11:00
63.G*3i 05:57:00 05:11:00
64.P*7g 05:57:00 05:28:00
65.P*7i 06:39:00 05:28:00
66.R*2f 06:39:00 06:11:00
67.+B9ax7c 06:54:00 06:11:00
68.+B2g-2h 06:54:00 06:11:00
Habu is desperately trying to get back into the game and almost gets his
reward here.
69.G3ix2h? 07:00:00 06:11:00
This turns the game into a very close fight. Correct was to have the
promoted bishop work in defense with 69.+B8d. For example 70.+Bx3i Sx3i
Rx2i+ R*7a and the black attack is very strong (N*4e is answered by Gx7g
and P*5g K7h +Rx3i P*2d).
70.R2fx2h+ 07:00:00 06:16:00
71.S*5i 07:00:00 06:16:00
72.P*5g 07:00:00 06:48:00
73.L5hx5g 07:09:00 06:48:00
74.+R2hx1i 07:09:00 07:27:00
75.R*7a 07:20:00 07:27:00
76.+R1ix2i 07:20:00 07:27:00
77.G8gx7g 07:22:00 07:27:00
78.G*4i 07:22:00 07:32:00
79.K6i-7h 07:28:00 07:32:00
80.G4ix5i 07:28:00 07:33:00
81.S4hx5i 07:32:00 07:33:00
82.+R2ix5i 07:32:00 07:33:00
83.P2e-2d 07:33:00 07:33:00
84.P2cx2d 07:33:00 07:34:00
85.P*2c 07:46:00 07:34:00
86.G3bx2c 07:46:00 07:34:00
87.G*3a 08:04:00 07:34:00
88.L*4a 08:04:00 07:45:00
89.G3ax4a 08:13:00 07:45:00
90.G4bx4a 08:13:00 07:46:00
91.R7ax4a+ 08:13:00 07:46:00
92.G*3a 08:13:00 07:46:00
93.+R4a-5b 08:15:00 07:46:00
94.S*3b 08:15:00 07:46:00
95.+B7c-8d 08:22:00 07:46:00
96.N*4e 08:22:00 07:49:00
97.L*4f 08:26:00 07:49:00
98.P*5a 08:26:00 08:00:00
99.+R5b-9b 08:31:00 08:00:00
100.N4ex5g+ 08:31:00 08:00:00
101.L4fx4c+ 08:31:00 08:00:00
102.P*4b 08:31:00 08:00:00
103.+L4cx3c 08:38:00 08:00:00
104.G2cx3c 08:38:00 08:05:00
105.P*2c 08:38:00 08:05:00
106.K2bx2c 08:38:00 08:10:00
107.N*1e 08:41:00 08:10:00
108.K2c-1b 08:41:00 08:10:00
109.P*2c 08:41:00 08:10:00
110.S3bx2c 08:41:00 08:10:00
111.P*2b 08:43:00 08:10:00
112.K1bx2b 08:43:00 08:10:00
113.+B8dx5a 08:43:00 08:10:00
114.L*4a 08:43:00 08:11:00
115.B*7e! 08:51:00 08:11:00
What seemed likely to be a routine win for Moriuchi and an early end to
the game has turned into a very exciting endgame. Unfortunately for
Habu, Moriuchi still has the lead in this endgame and with 115.B*7e he
ensures it. A lance drop on 7d is inviting, but Bx4b+ is too strong to
play that. Also 116.P1d is answered by 117.Bx4b+ Lx4b +Bx4b Gx4b +Rx4b
L*3b S*3a K1c +Rx3c and black wins.
116.S*6d 08:51:00 08:52:00
117.B7ex9c+ 08:51:00 08:52:00
This opens the escape route for the black king up the board. An entering
king becomes unavoidable, but the white king has no hope of entering.
118.P*7e 08:51:00 08:54:00
119.S7f-8e 08:51:00 08:54:00
120.+N5gx5f 08:51:00 08:55:00

129.+B9cx8d 08:57:00 08:58:00
130.S*7c 08:57:00 08:58:00
131.K7f-8e 08:57:00 08:58:00

138.G3c-3b 08:58:00 08:59:00
139.+R9b-8a 08:59:00 08:59:00
140.G3ax4a 08:59:00 08:59:00
141.S5bx4a= 08:59:00 08:59:00
142.+N6fx7g 08:59:00 08:59:00
143.G*4d 08:59:00 08:59:00
144.P*5a 08:59:00 08:59:00
145.S4ax3b+ 08:59:00 08:59:00
146.S2cx3b 08:59:00 08:59:00
147.P*2c 08:59:00 08:59:00
148.S3bx2c 08:59:00 08:59:00
149.S*3a 08:59:00 08:59:00
150.K2bx3a 08:59:00 08:59:00
151.N1ex2c= 08:59:00 08:59:00
152.K3a-3b 08:59:00 08:59:00
153.G*3a 08:59:00 08:59:00
154.K3b-2b 08:59:00 08:59:00
155.G3ax2a 08:59:00 08:59:00
156.K2bx2a 08:59:00 08:59:00
157.P*2b 08:59:00 08:59:00
Resigns 08:59:00 08:59:00
And now 158.K1b Nx1a+ Kx1a (K2c N*1e also leads to mate) P2a+ Kx2a L*2c
followed by G*3c and white has no defense, so Habu resigned here. Again,
the black player wins, but Habu will have taken some comfort in how he
managed to keep the game close despite the early middle game problems.
Still, he needs to keep his service game as well to avoid going 1-3 down.

49.P*6h 04:11:00 04:14:00
50.K3a-2b 04:11:00 04:20:00
Very unnatural to give up the initiative after the very aggressive
48.B*4i, but it is too risky to go all out attack, most likely giving up
a bishop in the process. This bishop would come back to hunt white with
B*5c or B*7e as long as the king is on 3a.
51.B8bx9a+ 04:25:00 04:20:00
52.G5a-4b 04:25:00 04:24:00
53.L*5h! 04:59:00 04:24:00
Very strong defensive move that forced Habu into additional material
sacrifice.
54.S6ex7f 04:59:00 05:11:00
This sacrifices an inordinate amount of material, but the alternative
54.P*7e K5i Px7f Kx4i Px7g+ G7g-6g S6f P*7f seems to stop the white attack.
55.G6gx7f 05:16:00 05:11:00
56.R7dx7f 05:16:00 05:11:00
57.S7gx7f 05:16:00 05:11:00
58.P*8g 05:16:00 05:11:00
59.G8hx8g 05:45:00 05:11:00

61.R2hx2g 05:52:00 05:11:00

64.P*7g 05:57:00 05:28:00
65.P*7i 06:39:00 05:28:00
66.R*2f 06:39:00 06:11:00
67.+B9ax7c 06:54:00 06:11:00
68.+B2g-2h 06:54:00 06:11:00
Habu is desperately trying to get back into the game and almost gets his
reward here.
69.G3ix2h? 07:00:00 06:11:00
This turns the game into a very close fight. Correct was to have the
promoted bishop work in defense with 69.+B8d. For example 70.+Bx3i Sx3i
Rx2i+ R*7a and the black attack is very strong (N*4e is answered by Gx7g
and P*5g K7h +Rx3i P*2d).
70.R2fx2h+ 07:00:00 06:16:00
71.S*5i 07:00:00 06:16:00

114.L*4a 08:43:00 08:11:00
115.B*7e! 08:51:00 08:11:00
What seemed likely to be a routine win for Moriuchi and an early end to
the game has turned into a very exciting endgame. Unfortunately for
Habu, Moriuchi still has the lead in this endgame and with 115.B*7e he
ensures it. A lance drop on 7d is inviting, but Bx4b+ is too strong to
play that. Also 116.P1d is answered by 117.Bx4b+ Lx4b +Bx4b Gx4b +Rx4b
L*3b S*3a K1c +Rx3c and black wins.
116.S*6d 08:51:00 08:52:00
117.B7ex9c+ 08:51:00 08:52:00
This opens the escape route for the black king up the board. An entering
king becomes unavoidable, but the white king has no hope of entering.

157.P*2b 08:59:00 08:59:00
Resigns 08:59:00 08:59:00
And now 158.K1b Nx1a+ Kx1a (K2c N*1e also leads to mate) P2a+ Kx2a L*2c
followed by G*3c and white has no defense, so Habu resigned here. Again,
the black player wins, but Habu will have taken some comfort in how he
managed to keep the game close despite the early middle game problems.
Still, he needs to keep his service game as well to avoid going 1-3 down.
