Diagram 1

Both players play a similar strategy to game 2: Habu the hineribisha 
and Sato a climbing silver. Still, the colors are reversed here and the 
position also has more differences than similarities.

Diagram 2

52.G5b-6c    05:02:00  05:29:00

A change of plan. Sato originally intended to go for the silver with 
52.P*7e, but he realized in time that after 53.P7c+ Nx7c P*7d Px7f 
Rx7f G6c Px7c+ Sx7c N*4e S4d Nx3c+ Sx3c, black has the strong attack 
P1d Px1d P*1b Lx1b G*1b. Fortunately for white, there are several 
other options here. 52.R7b is also a good move, but 52.G*6c is 
probably the most active one. Habu admitted after the game that he 
didn't have much confidence in the position here.

Diagram 3

68.G3c-2c!   06:28:00  06:34:00

An interesting position. The white king looks very exposed, but black 
has no good way to open the position to try and make use of that. The 
position looks a little like the two piece handicap joseki, where the 
king is also in the middle of the board, but far from easy to mate.

83.P*2e      07:12:00  07:16:00

In the two title matches between Habu and Sato, we have seen a lot 
of early fireworks. However, in this game both players show a different 
side of their shogi: patience. It has taken them 83 moves and almost 
all of their thinking time to finally start the hostilities. Perhaps 
not a great service to the fans, but this is also an important part 
of professional shogi.

84.P2dx2e    07:12:00  07:16:00
85.N3gx2e    07:12:00  07:16:00

90.N*3c      07:12:00  07:22:00

Diagram 4

Interesting point in the game. With this move, Sato shows that he is 
in control of the position. White threatens a strong attack with P4e 
next and if black defends with N*3g the attack with 83.P*2e would be 
pointless (black just loses a move). Habu is therefore forced to open 
the game here. Ironically, Sato's position turns out to be quite 
vulnerable to black's attack. Sato may have been able to make Habu 
jump through a hoop here, but he is shooting himself in the foot at 
the same time.

91.P8f-8e    07:22:00  07:22:00
92.N7cx8e    07:22:00  07:22:00

99.R2i-6i!   07:32:00  07:35:00

Diagram 5

Great move. This looks extremely show, but this is not the case. If 
white goes for the knight with 100.P*8e, then black wins very quickly 
after 101.P6f Px6f Gx6f P*6e Gx6e Sx6e P*6d Kx6d N*7f.

100.P4d-4e?! 07:32:00  07:43:00

After the game, there was no clear mistake found in Sato's play, but 
this move might have overstretched the white position. 100.K5b might 
have been better.

101.P6g-6f   07:33:00  07:43:00
102.N*5e?!   07:33:00  07:50:00

Looks like a strong shobute that had some commentators in the press 
room speculating about Sato taking the Osho title. However, this 
move backfires as Habu has a very nice reply. Better might have 
been 102.Px6f, but after 103.Gx6f P*6h Rx6h Px4f Bx4f Rx4f Gx4f it 
is hard to find a good move for white despite the fact that the 
black pieces are all over the place. B*7i is answered by P*6i and 
N*4e is not very effective after K5h.

103.P5fx5e   07:36:00  07:50:00
104.S6dx5e   07:36:00  07:50:00
105.N*6g!    07:36:00  07:50:00

Diagram 6

Great move. White can't take on 4f now, as black captures the silver 
on 5e with check. Also, 106.Sx4f P*4c Rx4c Gx4f Px4f N*5e wins the 
rook and is good for black.

106.B5c-2f   07:36:00  07:54:00

Diagram 7

113.N6gx7e!  07:47:00  07:58:00

Nice finish. The knight on 6g has done an important job and is now 
sacrificed to open up the lines to the king, win the rook on 4b and 
decide the game.

Final Diagram

Mate after 128.Sx7e R*7c Gx7c Px7c+ Kx7c N*6e etc. A tight game where 
the fighting started very late. Habu saves his Osho title for at least 
another game. Still, he is 2-3 down and needs to win both of the 
remaining games to defend his title. Especially game 6 will be important, 
as Sato will play with the black pieces then.
