59.P1g-1f?!  01:50:00  01:15:00

Diagram 1

Lately Sato either plays a wild new idea or the latest opening line. In this 
game it is the latter with a classic Yagura opening where black has built a 
strong formation with four generals in the castle and vanguard pawns on 6e 
and 7e. White tries to break through by attacking these vanguard pawns. 
59.P1f may be a questionable move. If white replies with 60.P1d this is good 
for black because the edge attack is strong. However, Watanabe uses this move 
to start the counter attack.

60.P4d-4e    01:50:00  01:32:00
61.B4f-3g    02:19:00  01:32:00

No choice. If 61.B2h or 61.B5g, white answers with 62.B5c, aiming at the pawn 
on 2f. However, moving the bishop to 3g also has a problem: white can attack 
the head of this bishop with the next move.

62.P3d-3e    02:19:00  01:36:00
63.B3g-4h    02:19:00  01:36:00
64.P3ex3f    02:19:00  01:50:00
65.B4h-5g    02:19:00  01:50:00

This is clearly not what black had in mind when playing 59.P1f. After 52.P4e, 
this bishop could go to 5g in one move, but now was forced to take three moves 
to get to the same square.

66.B4b-5c    02:19:00  02:10:00
67.R3hx3f    02:19:00  02:10:00
68.N8a-7c    02:19:00  02:16:00
69.S7g-7f    02:32:00  02:16:00
70.P*3d      02:32:00  02:27:00
71.S6f-7g    02:45:00  02:27:00
72.P*6d!     02:45:00  02:28:00

Diagram 2

The right time to start the attack against the vanguard pawn on 6e. If white 
allows B6f he will be in trouble, but if black plays 73.B6f here, white can 
answer with 74.N3c Nx3c+ Sx3c N*2e N*4d and the counter attack on the 6th file 
is worth more than than the slight loss in material.

73.P4g-4f    03:14:00  02:28:00
74.P6dx6e    03:14:00  02:53:00

100.B*6i     03:42:00  03:40:00

Diagram 3

It seems like Sato is attacking strongly, but this move shows that the black 
attack may not be strong enough and that the white counter attack is at least 
as dangerous.

101.G6g-6h   03:46:00  03:40:00
102.B6ix7h+! 03:46:00  03:45:00

Going in strongly. 102.Bx2e+ also seems possible, but as always Watanabe plays 
very positively.

103.G6hx7h   03:46:00  03:45:00
104.S7d-8e!  03:46:00  03:48:00

This looks very dangerous, but is probably better than the more natural 104.P*7e. 
At least it puts a lot of pressure on Sato.

105.P*3c     03:53:00  03:48:00

Diagram 4

A very interesting difference of opinion here. Sato was convinced that white had 
to take this pawn and was only looking at 106.Gx3c G*4c and after G*3b he thought 
that he might have to settle for sennichite after Gx3c Gx3c G*4c, etc. On the 
other hand, Watanabe said that he never even considered taking the pawn on 3c, 
feeling that this was a chance to attack.

106.S8ex7f   03:53:00  03:48:00
107.P3cx3b+  03:54:00  03:48:00
108.R9bx3b   03:54:00  03:49:00

Watanabe's reasoning is straightforward. With this rook on 3b it will be very 
hard for black to mate the white king, even with many pieces in hand. This might 
give white the time to gives his attack decisive momentum.

109.S7gx7f   03:57:00  03:49:00
110.N*6f     03:57:00  03:52:00
111.B*6g?!   03:57:00  03:52:00

A better alternative was probably 111.G*6h. For example, 112.Nx7h+ Gx7h N*6f 
B*6g Nx7h+ Bx7h R*2h B*8f! is a mating threat while defending against white's 
mating threat. Still, this is not decisive, as white can play things like G*7g 
Bx7g G*6f or S*7i Kx7i G*6h Bx6h G*6i Bx6i G*8h which are not clear at all.

112.N6fx7h+  03:57:00  03:52:00
113.B6gx7h   03:57:00  03:52:00
114.R*2h     03:57:00  03:53:00

Diagram 5

115.B*4f?    03:59:00  03:53:00

Here 115.G*6i was the best move. For example, 116.P*7g Nx7g N*6d is answered 
by B*6g Nx7f Bx7f G*6f G*6h and now G*7f is not a mating threat so black can 
win after P4c+. However, first S*8f (a mating threat) Px8f G*7f is a mating 
threat, although black still seems to have defensive options here with the 
threat of P4c+ ever looming if the white attack runs out of steam.

116.P*7g!    03:59:00  03:58:00

The decisive move.

117.B4fx2h   03:59:00  03:58:00

No choice. 117.Nx7g Rx7h+ Kx7h N*6f leads to mate.

118.P7gx7h+  03:59:00  03:58:00
119.K8hx7h   03:59:00  03:58:00
120.P*7g     03:59:00  03:58:00
121.K7h-6i   03:59:00  03:58:00
122.B*3f     03:59:00  03:58:00
123.P*5h     03:59:00  03:58:00
124.N*5g     03:59:00  03:58:00
125.K6i-6h   03:59:00  03:58:00
126.S*7i     03:59:00  03:59:00
Resigns      03:59:00  03:59:00

Final Diagram

Mate after 127.Kx5g G*4g K5f G*6f or 127.Kx7g G*6f K8f Gx7f Kx7f Bx5h+. A great 
win by Watanabe with the white pieces and with his back against the wall. In the 
two weeks leading up to this game he had lost five games in a row for the first 
time in his career. But when the going gets tough, the tough get going and Watanabe 
responds with a brilliant game where his positive playing style worked to perfection. 
With the black pieces in the next game, he suddenly is back in this match.
