23.G5h-6g 00:12:00 00:22:00
The final game of this epic battle for the Oza title is not a Yokofudori,
but a classic Yagura. The Yagura is said to favor black these days, so
it will be interesting to see what Habu has up his sleeve.

55.P6e-6d 01:21:00 01:34:00
56.P6cx6d!? 01:21:00 01:35:00
Even though the move order is slightly different, this game has followed
the NHK Cup game between Nakai and Hatakeyama Mamoru, which was played
in June. Ladies Meijin Nakai scored a rare victory against a strong
professional in that game. 56.Px6d is Habu's new idea. It is not a
very natural move, since it closes the bishop diagonal and opens a
drop square on 6c. However, Habu plans to play P6e next and use the
square 6f as the base for his attack. The question is whether he will
have time to make that work.
57.B6hx3e 02:05:00 01:35:00
58.P*3d 02:05:00 01:43:00
59.B3e-6h 02:10:00 01:43:00

73.P8gx8f 03:12:00 02:48:00
74.N*6f 03:12:00 02:52:00
75.S7gx6f? 03:29:00 02:52:00
A mistake. In the press room close to 20 professionals (among them A
class Junisen members Moriuchi, Sato, Aono and Suzuki Daisuke) had
gathered and they unanimously judged that black had the better position
here. However, 76.Sx6f turns the tables in Habu's favor. The right
move was 75.L1a+. Then after 76.P*1c Lx1c+! (the move that Watanabe
overlooked) Nx1c R1h black has the stronger attack. For example,
Nx7h+ Kx7h P*1d S*2a G3b-3c Rx1d L*3e +L1b K3a Rx1c+ and black has
broken through.
76.P6ex6f 03:29:00 02:52:00
77.G6gx6f 03:29:00 02:52:00
78.P*8e 03:29:00 02:55:00
79.L1e-1b+ 03:36:00 02:55:00
80.K2b-3a 03:36:00 02:55:00
81.S*6c! 03:36:00 02:55:00
Watanabe shows his fighting spirit. This move works both in attack and
defense. It makes it hard for the white king to escape and there is
always the tesuji threat of P*8c Rx8c Sx7d+ with attack on rook and
bishop.
82.P8ex8f 03:36:00 03:45:00
83.N*7i 03:39:00 03:45:00

94.S2gx1h+ 03:58:00 04:13:00
95.P5f-5e 04:08:00 04:13:00
96.B7c-8d? 04:08:00 04:20:00
Watanabe has successfully managed to complicate the position and this
has invited a Habu mistake. Here 96.P8g+ was correct. Then 97.Kx8g P*6e
Gx6e P*6g and white threatens lance drops on 6d or 8d next. This
leaves black without defense.
97.P7f-7e 04:10:00 04:20:00
98.G*6d 04:10:00 04:20:00
An Oyama-like attempt to completely kill the black attack.
99.S*7b! 04:15:00 04:20:00
This way of hooking silvers is usually not good. However, in this case
it is the only way to keep the attacking threats in the position.
Habu is very lucky that there is still a way to win in this position.
100.P*1a 04:15:00 04:28:00
101.+L1bx1a 04:21:00 04:28:00

109.L*1i 04:34:00 04:30:00
110.P8f-8g+! 04:34:00 04:36:00
The second time Habu finds the winning pawn sacrifice. 111.Nx8g fails
to 112.G7f Lx1g P*6f.
111.K7hx8g 04:46:00 04:36:00
112.P*6g 04:46:00 04:36:00

119.R6h-1h 04:59:00 04:41:00
120.B8dx7e! 04:59:00 04:42:00
The decisive move. The bishop comes into play and white even threatens
to bring the rook into attack with R8d next.
121.S*8e 04:59:00 04:42:00
122.P*8f 04:59:00 04:44:00

128.G*6h 04:59:00 04:45:00
Resigns 04:59:00 04:45:00
Watanabe shows his disappointment by playing on until a mate that
even a beginner can find. He pushed Habu to the edge in this match,
but was unable to deal the final blow. Habu gets his 12th consecutive
Oza title as a reward for his resilience. However, without a doubt
Watanabe will get a chance for revenge in the near future. This is
not going to be the last Habu-Watanabe match.
