17.R2h-8h 00:14:00 00:35:00
This is the 66th official encounter between Habu and Moriuchi (Habu leads 35-30),
but this is the first Ai-Furibisha opening they have played. Not really surprising,
as both players are Ibisha players by nature and for Ai-Furibisha both players
must be really willing to play Furibisha.
18.G4a-5b 00:14:00 00:44:00
19.P8g-8f 00:20:00 00:44:00
20.P5c-5d 00:20:00 00:53:00
21.P8f-8e 00:31:00 00:53:00
22.S4b-5c 00:31:00 00:53:00
23.P6f-6e!? 01:05:00 00:53:00
For a long time the Ai-Furibisha has been more or less unexplored territory,
but in the past couple of years the opening preparation in this opening has
also become very important. However, 23.P6e was a surprise. Opening the bishop
diagonal with the king still on 5i looks very bold. Not a move one would expect
for someone who is one loss away from being swept. Normal would be 23.G3h, but
then white can strengthen his castle with 24.P6d and 25.G5b-6c and the game will
continue at a slow pace. 23.P6e does not allow white the comfort of a waiting game.
24.P2d-2e 01:05:00 01:49:00
Habu responds to challenge and allows black a promoted bishop, using this time
to set up an attack against the still poorly protected king.
25.G4i-3h 01:16:00 01:49:00
26.B3cx7g+ 01:16:00 01:50:00
27.N8ix7g 01:16:00 01:50:00
28.S5c-4d 01:16:00 01:50:00
29.B*3a 01:54:00 01:50:00
30.R2b-2d 01:54:00 02:06:00
31.B3a-7e+ 01:57:00 02:06:00
32.P3d-3e 01:57:00 02:06:00
33.P3fx3e 02:50:00 02:06:00
34.P2e-2f 02:50:00 02:08:00
35.P2gx2f 03:05:00 02:08:00
36.S4dx3e 03:05:00 02:08:00
37.K5i-6h 03:05:00 02:08:00
38.B*4i?! 03:05:00 03:02:00
This gives white also a promoted bishop, but it turns out that he can not
keep it. Whether this move is the cause of the white problems or if things
went wrong earlier is not clear at this point.
39.G3h-3i 03:21:00 03:02:00
40.B4i-2g+ 03:21:00 03:02:00
41.P8e-8d 03:22:00 03:02:00
42.P8cx8d 03:22:00 03:02:00
43.P*3f! 03:36:00 03:02:00
Suddenly white is in big trouble. The move he wants to play is 44.Sx2f,
but then P*2h +Bx3g Nx3g Sx3g+ B*3e forks rook and king. Instead of +Bx3g,
the move Sx3g+ is better but after Px2g +Sx3f there is a big difference in
material and black seems to have the upper hand.
44.S3e-4d 03:36:00 03:16:00
No choice. The other alternative 44.Sx3f fails to 45.Sx3f +Bx3f S*2e.
45.+B7ex8d! 03:53:00 03:16:00
Good move. 45.Rx8d P*8c R8i is almost automatic, because the black rook
is better on 8i than on 8h. However, in this case 45.+Bx8d is the best
move since 46.P*8c fails to +Bx8c Sx8c Rx8c+ P*8b +R8h which is very
good for black.
46.P*8b 03:53:00 03:44:00
No choice again. Blocking the escape route of the king is a very painful
move and ultimately decisive.
47.K6h-7i 04:10:00 03:44:00
48.+B2gx3g 04:10:00 04:24:00
49.N2ix3g 04:10:00 04:24:00
50.R2dx2f 04:10:00 04:24:00
51.G3i-2h! 04:31:00 04:24:00
Allowing the rook promotion would make this a very long battle, but putting
the gold here, only protected by the rook on 8h is not an easy move to play.
Accurate calculation is vital, but Moriuchi has no problem with this. After
the game he said that here he felt sure he would be winning this game.
52.S*8f 04:31:00 04:28:00
53.+B8d-6f 04:40:00 04:28:00
54.S8f-8g+ 04:40:00 04:28:00
55.R8h-6h 04:48:00 04:28:00
And white has run out of decent moves. Habu tries everything to make something
happen, but to no avail.
56.P*2g 04:48:00 04:31:00
57.G2h-3h 04:48:00 04:31:00
58.P*3e 04:48:00 04:31:00

69.+B7g-6f 04:58:00 04:35:00
70.R2f-2i+ 04:58:00 04:36:00
71.+S4dx5d 04:58:00 04:36:00
72.+P3h-4i 04:58:00 04:42:00
73.B*3e 04:58:00 04:42:00
74.G*6b 04:58:00 04:42:00
75.K7i-7h 04:58:00 04:42:00
76.+P4i-5i 04:58:00 04:43:00
77.G6i-7i 04:58:00 04:43:00
78.+R2ix1i 04:58:00 04:47:00
79.S*8f 04:58:00 04:47:00
Finally, the professionals in the press room agreed that Moriuchi's
assessment after 51.G2h was correct. Black is winning.
80.L*3d 04:58:00 04:48:00
81.B3ex6b+ 04:58:00 04:48:00
82.G6ax6b 04:58:00 04:48:00
83.G*5c 04:58:00 04:48:00
84.B*2f 04:58:00 04:52:00
85.G5cx6b 04:58:00 04:52:00
86.G5bx6b 04:58:00 04:52:00
87.P*2g 04:59:00 04:52:00
88.B2fx1g+ 04:59:00 04:53:00
89.S8fx8e 04:59:00 04:53:00
90.+B1g-3e 04:59:00 04:56:00
91.G*4f 04:59:00 04:56:00
92.+B3ex4e 04:59:00 04:56:00
93.G4fx4e 04:59:00 04:56:00
94.N*8f 04:59:00 04:56:00
95.K7h-8g 04:59:00 04:56:00
96.+P5i-5h 04:59:00 04:56:00
97.B*2f 04:59:00 04:56:00
98.G*5b 04:59:00 04:57:00
99.G4ex3d 04:59:00 04:57:00
100.+P5hx6h 04:59:00 04:58:00
101.G3dx4c 04:59:00 04:58:00
Resigns 04:59:00 04:59:00
This is not a mating threat, but neither is 102.+Px6g or 102.+Rx7i,
so after both moves black wins with 103.Gx5b. Finally, 102.Gx4c +Sx4c
leaves white without defense. A good game by Moriuchi, who played his
best shogi with his back against the wall. With this win he ends a five
game losing streak in title match games and snaps a six game winning
streak in title match games by Habu. He is still in big trouble, but
winning the next game would really shift the momentum in his favor.
