54.K3a-2b          0/168        9/183

Actually, the game is only beginning now. Both players have taken their time
to build the strongest possible position.

55.G6h-5h          19/187       0/183
56.S3c-2d          0/187        13/196

Diagram 1

In the pressroom there was already talk of sennichite, after repeatedly
G5h-6h-5h and S3c-2d-3c. However, Miura actually has a cunning plan...

57.G5h-6g          3/190        0/196
58.S2d-3c          0/190        5/201
59.G6g-6h          0/190        0/201
60.S3c-2d          0/190        4/205
61.P4f-4e!         7/197        0/205

Diagram 2

Brilliant opening play by Miura. By playing the triangle gold manouver 
G6h-6g-6h he has managed to get the optimal defending position while Yashiki
has weakened his king with S2d. This is the time to start to attack.

62.P4dx4e          0/197        10/215
63.N2i-3g          8/205        0/215
64.P*8e!           0/205        15/230

Diagram 3

Great counter by Yashiki. Miura would have been very happy if Yashiki would
have played 64.P4f immediately: 64.P4f? P*4d Gx4d B*7a R5b Rx2d Px2d S*4a
and black wins. However, with blacks pawn on 8e, white has the counter P*8f
Sx8f P*8g and the rook sacrifice on 2d would be too dangerous for black.

65.P8fx8e          0/205        0/230
66.P4e-4f          0/205        2/232
67.P8e-8d!         12/217       0/232

Diagram 4
 

This move is actually very difficult to deal with. After 68.Rx8d P*8f the
weakness on the head of the black king is gone and the white rook no longer
works well in defense. After 68.P*8f Sx8f Rx8d P*8g black's castle is also
intact. Finally, in the future black has the sacrifice P8c+ Rx8c B*6a.

68.P4f-4g+         0/217        19/251
69.S5fx4g          3/220        0/251
70.P6d-6e?!        0/220        1/252

A mistake that opens the diagonal to the rook. From now on, white has to worry
about a bishop fork on rook and king on every move.

71.P6fx6e          17/237       0/252
72.P7d-7e          0/237        1/253
73.P7fx7e          3/240        0/253
74.R8bx8d          0/240        1/254
75.P*8e            0/240        0/254
76.R8d-8b          0/240        3/257
77.B*6d            3/243        0/257
78.B*7c            0/243        4/261
79.P7e-7d?         10/253       0/261

Diagram 5

A mistake that tips the scales slightly in Yashiki's favour. After 79.S5f the 
position is unclear.

80.B7cx6d          0/253        0/261
81.P6ex6d          0/253        0/261
82.P*8f            0/253        2/263
83.S8g-7f          0/253        0/263
84.S2d-3c          0/253        5/268
85.P6d-6c+         15/268       0/268
86.S5dx6c          0/268        0/268
87.P*2d            5/273        0/268
88.P2cx2d          0/273        0/268
89.P*2c            0/273        0/268
90.G3bx2c          0/273        3/271
91.P*2e            2/275        0/271
92.P2dx2e          0/275        11/282
93.P*2d            0/275        0/282
94.G2cx2d          0/275        2/284
95.N3gx2e          0/275        0/284
96.P*2g            0/275        8/292
97.R2hx2g          0/275        0/292
98.P*2f!           0/275        3/295

Diagram 5

The right move. Very tempting is the bishop drop 98.B*4i, but both players
had seen that after 99.Nx3c+ Gx3c Rx2d Gx2d B*5e P*4d S5h white has no
continuation.

99.R2gx2f          0/275        0/295
100.B*4d           0/275        0/295
101.P3f-3e         1/276        0/295
102.P*7e           0/276        1/296
103.S7fx7e         3/279        0/296
104.P*7f           0/279        0/296
105.N2ex3c+        0/279        0/296
106.G4cx3c         0/279        0/296
107.R2fx7f         0/279        0/296
108.N*6d           0/279        0/296
109.S7ex6d         2/281        0/296
110.S6cx6d         0/281        0/296
111.P*2e           3/284        0/296
112.G2dx3e         0/284        1/297
113.P2e-2d         7/291        0/297
114.S*8g           0/291        1/298
115.G7hx8g         0/291        0/298
116.P8fx8g+        0/291        0/298
117.K8hx8g         0/291        0/298
118.G*7e           0/291        0/298
119.R7fx7e?        3/294        0/298

Diagram 7

The losing move. Miura had planned to play 119.Rx7e Sx7e B*6e, but realised
too late that he would be mated after Rx8e: K7h (Nx8e R*8h) R*8h K6i Rx6h+
Kx6h R8h+ and after any drop on 7h, the game is finished after Bx7g+. If
Miura would have seen this earlier, he would probably have found the correct
119.S*2c Gx2c Px2c+ Kx2c B*4a S*3b P*2d and white does not get the time to
play the simple hisshi Gx7f Kx7f R*6f K8g Rx6h+.

120.S6dx7e         0/294        0/298
121.K8g-9h         2/296        0/298
122.S7e-8f         0/296        0/298

A very interesting way to lose. White has no immediate mate, but black can only
attack by giving white the material he needs to mate.

123.B*4a           1/297        0/298
124.K2b-3a         0/297        0/298
125.P*4b           1/298        0/298
126.R8bx4b         0/298        0/298
127.G*5a           1/299        0/298
128.R4bx4a         0/299        0/298
129.G5ax4a         0/299        0/298
130.K3ax4a         0/299        0/298
131.R*6a           0/299        0/298
132.B*5a           0/299        0/298
133.P*4b           0/299        0/298
134.K4ax4b         0/299        0/298
Resigns            0/299        0/298
Time:              04:59:00     04:58:00

Black has no mate, and there is no defense against G*8g K8i P*8h K7i R*8i.
