1.P7g-7f 05:44:00 00:00:00
After a one hour recess, the game is replayed with reversed
colors. The rules for the Osho match state that each player
is given at least two hours for the replay. Sato had used 6
hours and 5 minutes of the allotted 8 hours for the first game,
so he is given 2 hours. Habu had used 5 hours and 49 minutes, so
he is given 2 hours and 11 minutes plus the 5 minutes extra Sato
received in order to have a minimum of 2 hours.
2.P3c-3d 05:44:00 06:00:00
3.P2g-2f 05:44:00 06:00:00
4.P5c-5d 05:44:00 06:00:00
5.P2f-2e 05:46:00 06:00:00
6.R8b-5b 05:46:00 06:00:00
Having white in the replay with shorter time is usually a disadvantage,
but Sato's style is to open up the game quickly, whether he is black
or white, so for him it probably doesn't make much difference.
7.B8hx2b+ 05:48:00 06:00:00

9.P9g-9f 05:48:00 06:00:00
10.P9c-9d 05:48:00 06:00:00
11.S7i-7h 05:48:00 06:00:00
12.S7a-7b!?! 05:48:00 06:00:00
This looks too risky to be playable. The square 8b is a gaping hole
for a bishop drop...
13.K5i-6h 05:58:00 06:00:00
14.P5d-5e 05:58:00 06:03:00

24.K5a-6b 06:07:00 06:12:00
25.B*8b 06:10:00 06:12:00
Habu decides to call Sato's bluff. After all, a free bishop promotion
this early in the game has to be good, or...
26.L9a-9c 06:10:00 06:16:00
27.G6i-6h 06:14:00 06:16:00
28.R5b-5d! 06:14:00 06:42:00
A brilliant strategic novelty by Sato. He will use the black promoted
bishop as a target to support his edge attack by switching the rook
to the 9th file. If white can time the rook switch to the 9th file
well, black has to defend the promoted bishop and white gets an extra
move for his attack.
29.P8g-8f 06:42:00 06:42:00
30.G6a-7a 06:42:00 07:02:00
31.B8b-9a+ 06:42:00 07:02:00
32.P9d-9e 06:42:00 07:03:00
33.P9fx9e 06:43:00 07:03:00
34.P*9f 06:43:00 07:03:00
35.L9ix9f 06:44:00 07:03:00
36.B*7d 06:44:00 07:03:00
37.K7h-8g 06:44:00 07:03:00
38.R5d-5e! 06:44:00 07:04:00
Another great rook move. It is tempting to play 38.Bx9d here, but
after 39.Kx9d Lx9e Kx9e L*9c K8e the black king can't be mated. After
38.R5e white threatens to take with the rook on 9e instead of the lance,
which is of course devastating. Even though Habu us fully aware of this,
he has only pawns in hand which make it difficult to defend against
this threat.
39.P9e-9d 06:46:00 07:04:00
Probably best, but now white can achieve his goal: a successful breakthrough
on the edge.

60.K6bx7a 07:44:00 07:33:00
61.B*5c 07:55:00 07:33:00
62.L*6b 07:55:00 07:38:00
The deciding move. The black pieces on the left are all crying.
63.B5c-7e+ 07:58:00 07:38:00
This quickens the end, but the alternative 63.G*8b K6a Gx7b Kx7b S*8b also
wins for white after Sx5c +Bx8a K6a Px5c+ +P8g! Gx8g (Kx8g +L8h Gx8h B*9f
K7g +Rx8h Kx8h G*8g is mate) B*8h K6h B7i+ K5h +R9h N*7h G*6h K5g Gx6g K5f
P*5e and now Kx5d is not mate, but then S*4d followed by Sx5c takes the
black promoted pawn, after which black has no way to get to the white king.
This is also losing, but probably gives black slightly more chances than
in the game.
64.+L8i-8h 07:58:00 07:41:00
Sato still needs to be careful. Winning the bishop with 64.+P8g Gx8g +Rx9a
looks good, but after P*9f the rook is shut out and the white attack is
stopped.
65.S4h-5i 07:58:00 07:41:00
66.+L8hx7h 07:58:00 07:46:00
67.S6gx7h 07:58:00 07:46:00
68.+P9g-8h 07:58:00 07:46:00
Resigns 07:59:00 07:46:00
Black seems to have nothing else than 69.G*8b K6a Px5c+, but this isn't even
a mating threat, so white can just play +R9g L*8g N*5e and win easily in
attack. A very good start for Sato, who is looking to erase the painful
memories of last year's Osho match where he came back from 3-0 down, only
to lose the deciding seventh game.
