23.G6i-7h 00:39:00 00:24:00
24.L9a-9b 00:39:00 00:37:00
Finally, "The Furiana Prince" plays the Furibisha Anaguma where he got his nickname
from. Until now, he chose to fight Habu in the Ibisha opening, giving this match a
completely different flavor from the one he played against Fukaura last year.
25.L9i-9h 00:44:00 00:37:00
Habu answers with an Anaguma of his own. The double Anaguma opening is prone to
ending in sennichite, which happened twice in the match last year. Actually, the
fifth game of last year's match was played at the same venue and ended in sennichite.
The replay also was a long fight and the game ended at one o'clock in the morning,
actually making it a three day game. It is unclear if Hirose felt that this was a
burden on the hotel staff, but he promised before the game that he would not allow
it to end in sennichite this time.
26.K8b-9a 00:44:00 00:39:00

39.G6i-7i 01:16:00 01:02:00
40.P5c-5d 01:16:00 01:05:00
41.P1g-1f 01:17:00 01:05:00
This move is new. Until now, 41.P3f had been the main line. Hirose had experience
with this position, because he played it against Watanabe in last year's Kio
tournament (November 17th 2011). This game continued 42.P5e P2d Px2d P3e and Hirose
won. The problem of 41.P3f is that it opens the diagonal to the rook, helping white
to activate the bishop. Habu avoids this by playing the waiting move 41.P1f.
42.G6a-7a 01:17:00 01:25:00
43.P2e-2d 01:52:00 01:25:00

55.P2e-2d 02:36:00 03:02:00
56.P*2f 02:36:00 03:12:00
57.+B5ax5b 02:46:00 03:12:00
58.R2bx5b 02:46:00 03:22:00
59.S*4c 02:47:00 03:22:00
60.R5b-5a 02:47:00 03:25:00
61.S4cx3d+ 02:47:00 03:25:00
62.B4d-5c 02:47:00 03:27:00
63.P2d-2c+ 03:06:00 03:27:00
64.P5e-5f? 03:06:00 03:41:00
The white plan is to activate the major pieces with P5f and B6d, but it is not so
clear in which order these moves should be played. It turns out that Hirose should
have played 64.B6d here. The reason for this will become clear later.
65.P*5b 03:12:00 03:41:00
66.R5ax5b! 03:12:00 03:49:00
Strong reply. The obvious problem of this move is +S4c, and in the press room moves
like 66.Gx5b and 66.R6a were analyzed. With 66.Rx5b, Hirose dares Habu to play 67.+Sx4c.
67.+P2cx3c? 03:47:00 03:49:00
The sealed move and an important mistake. There were some interesting psychological
battles going on here. Black has the choice between 67.+Px3c and 67.+S4c, but Hirose
forcefully played 66.Rx5b, which makes Habu second guess the strength of the obvious
67.+S4c. The other thing was the strange statistic that so far in this match, whoever
sealed the move, lost the game. In the press room there was speculation that the
players would avoid sealing the move, playing a move quickly before the time control.
This did not happen and Habu sealed 67.+Px3c, just 9 minutes after the six o'clock
time control. After the correct 67.+S4c it follows 68.R5a +Sx5c Rx5c B*3e R5d +Px3c
and black has good fighting chances. Hirose could have avoided this variation by
playing 64.B6d instead of 64.P5f and this is the reason that 64.P5f was a bad move.
After 67.+Px3c, the silver on 3d becomes an idle piece, which is an important problem
for black.
68.B5c-6d 03:47:00 04:03:00
69.+P3c-4c 04:01:00 04:03:00
70.R5b-5e 04:01:00 04:05:00
71.R2hx2f 04:02:00 04:05:00
72.P5f-5g+ 04:02:00 04:07:00
73.P*5h! 04:20:00 04:07:00
Habu fights back strongly. In the press rooms there were visions of sennichite
after 74.P*5f Px5g Px5g+ P*5h etc. If not sennichite, then 74.Px5h is answered
by N*5f.
74.+P5g-5f! 04:20:00 04:29:00
Hirose keeps his promise of not playing sennichite. In the press room it was thought
that he didn't have much choice but to go for sennichite, as it looks very painful
to have to move this tokin backwards. However, Hirose has looked deeper.
75.R2f-2b+ 04:38:00 04:29:00
76.P6e-6f 04:38:00 04:42:00
77.P6gx6f 04:39:00 04:42:00
78.B*6g! 04:39:00 04:42:00
This is the type of move that requires a lot of Anaguma experience. Because of this
move, moving back the tokin with 75.+P5f is not slowing down the attack. For example,
79.G7h-6h P*5g is adding more firepower to the attack. If black doesn't defend, then
Bx7h+ Gx7h G*6g is too strong.
79.N*5i 04:43:00 04:42:00
Habu tries to keep the position together, but dropping this knight is painful because
this is the knight that he was ahead. Professionals are very much aware of material
difference, even in the endgame, and both Habu and Hirose said after the game that
white had the upper hand now, because the black material advantage was nullified here.
80.B6gx7h+ 04:43:00 05:03:00
81.G7ix7h 04:43:00 05:03:00
82.+P5fx6f 04:43:00 05:03:00
83.S7gx6f 04:55:00 05:03:00
84.R5ex5h+ 04:55:00 05:04:00
85.P*6h 04:55:00 05:04:00
86.+R5h-6i! 04:55:00 05:26:00
Looks strange, because it invites black to move the gold back with tempo to 7i, where
it is defended. Hirose again shows his extraordinary intuition in Anaguma positions,
as we will see. The obvious 86.+Rx5i is not clear after 87.B*4d P*6a +Rx1a and in the
press room 86.Bx3g+ followed by +Bx5i was analyzed, which also is not clear.
87.G7h-7i 05:28:00 05:26:00
The obvious reply, but it was important that 86.R6i also dealt with 87.+P5b. If then
88.Gx5b +Rx5b +Rx7h B*6g is not good for white, but 88.G6b-7b G7i +Rx5i +Rx1i +Rx5b
takes the vital tokin.
88.+R6ix5i 05:28:00 05:28:00
89.B*4d 05:28:00 05:28:00
90.P*6a 05:28:00 05:46:00
91.+R2bx1a 05:37:00 05:46:00
92.N*9e! 05:37:00 05:51:00
The second point of 86.R6i. By inviting the gold back to 7i, the main weakness of
the Anaguma, square 8g, is exposed. Hirose attacks it quickly, and it is very hard
to defend.
93.G7i-7h 05:49:00 05:51:00
94.+R5ix1i 05:49:00 06:01:00
95.+P4c-5b? 06:06:00 06:01:00
Habu throws the towel quickly and after the game said that he regretted that. He
could have made it a lot harder for Hirose had he played 95.+R5a here. This threatens
to shut out the white rook with P*5i next, so the obvious reply is 96.+R6i but after
97.L*7i L*8d +R5g black threatens P8f next and there doesn't seem to be an easy way
to continue the white attack. Therefore, white has to allow P*5i by playing 96.L*8d,
but then the position is not completely clear after 97.P*5i P*5e Sx5e Nx8g= (or +Rx5i
Sx6d +R5a +P5c) Sx8g Lx8g+ Gx8g S*8f G8h Bx5e +Rx5e S*8g N*7i.
96.L*8d 06:06:00 06:27:00
97.+P5bx6b 06:22:00 06:27:00
98.N9ex8g= 06:22:00 06:32:00
99.S8hx8g 06:22:00 06:32:00
100.G*7i 06:22:00 06:32:00
Resigns 06:24:00 06:32:00
As Habu explained: I can only play something like 101.K8h, but then 102.Lx8g+ Gx8g
+R6i G7g Gx8i K8g G*8h leads to mate. Again Hirose delivers with the white pieces
after playing a very strong game and he is now one win away from successfully
defending his Oi title. Can Habu force another game seven?
