9.P5g-5f 2/10 0/13
10.R8b-4b 0/10 6/19
This match started with a Yokofudori game, but since Tanigawa played
Shikenbisha in the second game, this has become another Furibisha
match with white ranging the rook for the fourth time in a row.

27.S7i-7h 8/111 0/145
28.P8c-8d 0/111 7/152
29.S5g-4f?! 56/167 0/152
This quick attack is in style, but combined with the left mino is does
not seem so strong, at least at this level.
30.S4c-3b!? 0/167 50/202
A move like the late Oyama used to play. Pulling back this silver is
a very good defence against the quick attack. When the bishop diagonal
is opened, white can take back on 3c with the silver and it is no
longer possible to break through on 2d.
31.K8g-9h 17/184 0/202
Tanigawa knows that attacking at this point would be unreasonable and
strengthens his king position instead.
32.P4d-4e 0/184 6/208
33.S4f-5g 7/191 0/208

49.N2i-3g 18/283 0/267
50.G6b-6a! 0/283 31/298
Subtle play. The normal 50.G6b-7b is answered by 51.P2d Px2d B*5a R2b
Nx4e S4b Bx4b+ Rx4b Rx2d Rx4e P4f R4a S*5b and black has a big advantage.
The gold on 6a defends against B*5a.
51.P1g-1f 48/331 0/298
52.P1c-1d 0/331 16/314
53.P3f-3e? 32/363 0/314
This is why Tanigawa has so many fans. With the bishops off, this has
become a typical sennichite position. Neither player can afford to open
the game with all the possible bishop drops. Tanigawa decides to
attack anyway, but as he himself said after the game: "Sennichite was
probably best".

66.L*2b 0/371 1/371
67.B2c-4a+?! 12/383 0/371
Better is probably 67.N2e G7b P3c+ Nx3c B3b+ Lx2d +Bx4b Bx2e R*2b and
black has a strong looking attack for the material loss.
68.R4bx4a 0/383 0/371
69.R2dx2b+ 0/383 0/371
70.G6a-7b 0/383 0/371

81.+P4b-4c 2/446 0/421
82.P6d-6e 0/446 5/426
Here it seems that white has big advantage, but...
83.L*5i! 9/455 0/426
This is a strong move that both defends and attacks. White's advantage
is not as big as it looked.
84.B3f-6i+ 0/455 9/435
85.G6gx5f 2/457 0/435
86.P8d-8e! 0/457 12/447
Habu takes a little time to compose himself and change his attack.
The planned 86.Sx5f is not so good after 87.Lx5f G*5h S*7i P*5e P*5d
Gx5d P*5i and white has a hard time to continue his attack.
87.G5fx5e 1/458 0/447
88.P8ex8f 0/458 2/449
89.S8gx8f 2/460 0/449
90.P*8g 0/460 0/449
91.K8hx8g 0/460 0/449
92.B*8i 0/460 5/454
93.S6h-7i 0/460 0/454
94.P*8e 0/460 0/454
95.N7gx8e 0/460 0/454
96.N7cx8e 0/460 0/454
97.P*8d? 1/461 0/454
How unfortunate for Tanigawa. By reversing the move order, his position
is suddenly lost. If 97.+P5c right away, he would still have had good
fighting chances. For example, 98.Gx5c P*8d Sx8d Gx6e P*5b Lx5c+ N*6g
P*8c K9c P9e black wins. According to Morishita, even after 97.+P5c the
black attack is probably not strong enough, but it seems clear that
it would have been Tanigawa's best chance.
98.S8cx8d 0/461 0/454
99.+P4c-5c 0/461 0/454
100.G6c-7c 0/461 7/461
101.+P5c-6b 4/465 0/461
102.K8b-9c! 0/465 0/461
Brilliant. The rook that was asleep on 8a for a long time wakes up
just in time to defend and help in mating the black king.
103.+P6bx7b 1/466 0/461
104.N*7e 0/466 0/461
Resigns 0/466 0/461
Time: 07:46:00 07:41:00
White wins after 105.Px7e Sx7e and now either Sx7e Px7e and no defence
or +Px7c Bx7h+ Sx7h Sx8f and mate. With this fine win Habu takes his
6th Osho title in a row and closes out a title match early for the
first time since he beat Moriuchi 3-1 in the Kio match almost a year
ago.
