Diagram 1

Habu seems to think that the quick attack is the only way to make things
hard for Fujii. This time he picks the N3g quick attacking system. Fujii
chooses a sharp counter with the silver moving straight to the head
of the black king.

30.S5d-6e    0/146     42/72
31.P7f-7e    29/175    0/72
32.P6c-6d    0/175     54/126

39.P2e-2d    5/239     0/136
40.B3cx2d!?  0/239     12/148

Diagram 2

Looks a bit risky, as this bishop can be taken at any time and there
is a gaping hole on 4c for a bishop drop. However, Fujii has calculated
that this is not a problem and that the bishop on 2d is much more
active than on 2c.

41.P7e-7d    71/310    0/148

The sealed move and the start of the real hostilities. Habu wants to
move the bishop to 9g and also drive back the silver with Px7c+ followed
by P*7g. 41.Rx2d Px2d B*4c looks very inviting, but after G3b Bx5b+
Gx4b R*4a R*2i followed by Rx1i+ and L*8d, the white attack is stronger.
Habu's biggest problem here seems to be time. After the first day, he
has used more than 5 hours, while Fujii has only used a little more
than 2 hours...

42.G4a-3b    0/310     69/217

Fujii wants to answer B9g with B4b, so he defends 2c with the gold.
The drawback is that with this gold so far away from the king, white's
position is not very solid. For the first time in his two matches
against Fujii, it seems that Habu has a reasonable position after
the opening. Still, it is too hard to say who is better here.

43.P7dx7c+   36/346    0/217
44.S7bx7c    0/346     1/218
45.P*7g      1/347     0/218
46.S7f-8e    0/347     0/218
47.R2hx2d    17/364    0/218
48.P2cx2d    0/364     0/218
49.B*6c      0/364     0/218
50.S8e-7d    0/364     5/223
51.B6cx5b+   0/364     0/223
52.G6ax5b    0/364     0/223
53.R*1a      0/364     0/223
54.P3d-3e!   0/364     87/310

Diagram 3

It seems that black has the better position. The white pieces are all
over the place and black has dropped his rook in the camp of the
opponent first. The big problem of the black position is the inactive
bishop on 8h. Because of this, things are still very difficult. Fujii's
54.P3e is a strong move, starting a counter attack on the head of the
black knight and at the same time opening the diagonal to the king so
that black can not take the lance on 1b.

55.R1ax2a+?! 0/364     0/310

Here Habu misses a good chance to get the better position. The knight
sacrifice 55.N4e! would have been the best move. Then, after 56.Px4e
Rx1b+ G3b-4b P5c+ white can try to play for the king-rook fork again
with Px4f, but after L*5f P*5e +Px5b Px5f Sx5f black is better. Fujii
planned to play G4bx5c P*5d B*3d (after P5c+), but then +Rx2a Px4f
N*6g black has good chances.

56.G3b-4b    0/364     3/313

The position of the golds seems a little odd, but they are actually
defending quite well. Black has a difficult time making any progress
here.

57.P3fx3e    28/392    0/313
58.B*2g      0/392     67/380

90.P*7e      0/458     7/444

Diagram 4

It seems that black's attack has run out of steam, so the general
opinion was that white had the advantage here. Fujii did not like 
90.L*8d after 91.P*5i, so he plays the attack on the head of the
bishop instead. However, this gives Habu a chance to play a brilliant
fighting move.

91.L5fx5c+!  5/463     0/444

The magic begins. This looks like a bad move, as white can take this
lance with attack on the black promoted rook. Losing that rook seems
to make black's attack even weaker...

92.+B6cx5c   0/463     0/444
93.P7fx7e!   1/464     0/444

This one-two punch shows Habu's endgame strength. He has judged that
94.+Bx4b Px7d Sx7d P*7e is good for black. Very hard to see for lesser
gods.

94.S7dx7e    0/464     13/457
95.P*9d      5/469     0/457
96.L*8d      0/469     4/461

Looks like a good move, as 96.Lx9d N*8e S7c-8d +Rx5c Px5c B*6c seems
good for black. The lance on 8d defends against N*8e and also threatens
Lx8g+ at some point, so Fujii thought he was safe here and would win
the game. In reality, things are extremely complicated here.

97.P9dx9c+   1/470     0/461
98.K8bx9c    0/470     0/461
99.P*9d      1/471     0/461
100.K9c-8b   0/471     0/461
101.+R4bx5c  5/476     0/461
102.P5bx5c   0/476     5/466
103.B*6c     2/478     0/466

Diagram 5

This looks like a weak attack and Habu said he only played it because
there was nothing else. It is a sign of the complexity of shogi that
no one could find a winning variation for white here.

104.L8dx8g+  0/478     1/467
105.K7h-6g   0/478     0/467
106.+L8gx7g  0/478     1/468
107.G6hx7g   0/478     0/468
108.+R1i-6i  0/478     1/469
109.G5h-6h!  0/478     0/469

Fujii seems to have underestimated this move. As this opens 5h for a
bishop drop, this does not look like a good defence. However, with the
bishop on 6c also working in defence, there is no mate.

110.S7e-7f   0/478     8/477

The obvious 110.B*5h K5f L*5d P*5e Lx5e K4f is not good enough. There is
no mate and the rook on 6i is still hanging.

111.K6g-5f   0/478     0/477
112.B*7d?    0/478     0/477

Diagram 6

Now black can take the promoted rook on 6i for free and white still
has no good attack. Black wins. Still, what else can white play?

113.B6cx7d+  0/478     0/477

Final Diagram

Mate after 130.K6b Lx7b+ +Bx7b Gx7b Kx7b L*7c K6b B*7a K5b R4b+ K6c
+Rx5c. A strange game where Fujii seems to have lost without making
a mistake. Habu's magical powers prevailed again. So despite his
problem's in the opening in this match, Habu has managed to get back
to 3-3 and suddenly has a very good chance to take the Ryu-O title
from Fujii, something that seemed very unlikely when he was 3-1 down.
For the fifth time in a row, a professional title match will be
decided in the final game.
