7.S7ix8h     00:02:00  00:03:00

After the disaster in the second game, the question was how 
Yamasaki would recover. One advantage is that the third game 
was played in Osaka, where he is based. Plenty of mental support, 
but he is not playing anybody. The opening is no surprise: the 
Kakugawari with tempo loss is one of Yamasaki's specialties.

26.R8b-4b    00:26:00  00:41:00

Yamasaki is trying to drag Habu into an open fight by changing 
tactics. This fourth file rook strategy has some similarities with 
the second game of the Meijin match, but the position is different 
enough for this to be of little help for Habu. However, Yamasaki 
might have overdone his attempts to try and confuse Habu a little.

27.G4i-5h    00:33:00  00:41:00
28.P6d-6e    00:33:00  00:44:00

33.S7gx6f    00:41:00  00:45:00
34.G6a-7b?   00:41:00  00:47:00

Diagram 1

Here Yamasaki realized that his opening strategy had been a failure. 
White wants to play 34.K6b here, but this fails to 35.B*8b. 34.G7b 
is played to defend against this, but turns out to be bad in combination 
with the next move. Better would have been directly 34.R6b. If then the 
same line as in the game 35.S4f K4b S6f-5e, the white gold is still on 
6a and can move to the right to support the king.

35.S3g-4f    00:54:00  00:47:00
36.R4b-6b    00:54:00  00:50:00
37.S6f-5e!   01:00:00  00:50:00

Diagram 2

Typical positive play by Habu. He is not happy with just getting a 
slightly better position after 37.G5h-6g, but seizes the moment to
try and inflict more damage upon the white position now that the pieces 
are in disarray. This is not something that can be done lightly. Deep 
calculation is needed to make sure that this is not an overplay.

38.S3c-4d    01:00:00  01:43:00
39.P2e-2d    01:31:00  01:43:00

49.S5ex4d    02:13:00  01:55:00
50.B*2b?     02:13:00  01:58:00

Diagram 3

Here is where Habu's deep calculations made the difference. Yamasaki 
thought in this position that Habu had made a mistake. The silver on 
4d seems hard to defend. For example, the obvious 51.B*8h fails to 
52.S5b and then P*6f is impossible. If Yamasaki would have calculated 
as deeply, he would have played 50.B*6d ad after 51.B*3g P*4c S*5e Px4d 
Sx6d Sx6d P*2d Px2d B*4f G6c Bx2d K5b white has two silvers for the 
bishop and good fighting chances.

51.P*2d!     02:21:00  01:58:00

Habu has seen deeper than Yamasaki. By taking the side pawn on 3d, he 
not only defends the silver, black also strengthens the attack. Realizing 
that he is being outplayed here must have been the final blow to 
Yamasaki's confidence. The quick collapse of the white position shows
a lack of fighting spirit.

52.P2cx2d    02:21:00  02:09:00

73.P*6c!     02:37:00  02:34:00

Winning. 74.Rx6c fails to 75.B*8a and after 74.Gx6c B*8a there is no 
defense against S*7b next.

74.R6b-1b    02:37:00  02:34:00
75.P3f-3e    02:42:00  02:34:00

78.G3c-3b    02:42:00  02:35:00

Blocking the sideways working of the rook is very painful, but white 
had no choice. 78.Gx3d Rx5e Sx5e B*4c or 78.G4c P*2d Px2d (Sx2d R2f) 
S*2c wins.

79.B*8a      02:45:00  02:35:00

85.P*2b!     02:48:00  02:37:00

The decisive move.

Final Diagram

Mate after 92.Rx1c Sx3b+ Kx3b G*3c or 92.K3a G*2a K4a B6c+. Not much in 
this game for Yamasaki, who apologized to his fans after the game. Habu 
defends his Asahi Open title for the first time, but rather than winning 
the match, the general feeling was that Yamasaki had lost it. If he could 
have taken his chances in the second game, the story might have been 
very different.
