23.P3f-3e 01:04:00 02:28:00
So far the game is following the A class Junisen game of February 1st
between the same players.
24.P4c-4d 01:04:00 02:28:00
This move is different. Even though Habu won the Junisen game, it is
clear that Sato has prepared something, so Habu changes the moves to
avoid Sato's homework.

41.B3ex2d 03:28:00 04:14:00
42.P*2e 03:28:00 04:14:00
43.R2h-3h! 04:19:00 04:14:00
This move shows that Sato's positive attitude has not changed even though
he is 3-0 behind. Black has won a pawn and 43.B6h seems good enough, but
Sato is looking for more, saying after the game that he didn't like 43.B6h
G5b P*2d G2b and it seems difficult for black to continue. 43.R3h is a
difficult move to play, because white seems to have the strong counter
44.B*2g. Many professionals would not have dared to play R3h because of
this, but Sato has analyzed this deeply and after the game he showed the
following variation: 44.B*2g R3g Bx4i+ Kx4i Gx2d Rx3c+ B*6i (S4c-5b K5h!
but not +Rx2d? because of B*5g threatening mate and rook) G6h Bx4g+ P*4h
P*3b +R4b G5b B*7a (Kx7a +R3a followed by Px4g).
44.S4c-3d 04:19:00 04:56:00
Habu confirms that Sato was right. Black has won the opening and Habu
doesn't seem to have much hope to recover with his pieces all over the
place.
45.B2d-6h 04:20:00 04:56:00
46.P2e-2f 04:20:00 04:57:00

55.K7i-8h 05:48:00 05:39:00
56.P7c-7d 05:48:00 05:59:00
57.P6g-6f! 06:15:00 05:59:00
Sato can not afford to be complacent. This move is necessary, because
white threatened to bring the rook into play with K7c. After P6f, K7c
is met with B3g and the black attack along the long diagonal is hard
to defend against.

85.+B6a-5a? 07:27:00 07:00:00
Just going for the bad silver on 3c is not good, letting Habu back in.
Correct was 85.+Bx2e N9c +B2f N8e +Bx3g.

108.G*3d 07:50:00 07:36:00
109.P*3e? 07:51:00 07:36:00
Correct was 109.B*2b.
110.S*5i! 07:51:00 07:36:00
Habu magic! This move was completely overlooked by Sato. If 110.+Bx5i
then Gx3e and the black rook dies.
111.+B6h-5g 07:55:00 07:36:00
112.S5i-4h= 07:55:00 07:36:00
113.+B5gx4h 07:55:00 07:36:00
Overlooking the silver drop must have been a shock for Sato, especially
when his time is running out. However, he has stayed cool and even
though losing the rook cannot be helped, the promoted bishop is placed
better on 4h than on 5i. Sato is very lucky that he still has a minuscule
edge in this position.

139.R*6a 07:57:00 07:59:00
Finally, the black win is clear.
140.S*7b 07:57:00 07:59:00
No choice. 140.Gx6h is answered by 141.S*8c K9c (Kx8c Rx6c+ S*7c S*7b
and mate) S*8b Kx8c Rx6c+ S*7c (or B*7c) Sx7c+ Nx7c S*7b and mate.
141.S*7a 07:57:00 07:59:00
142.K8b-9b 07:57:00 07:59:00
143.R6ax6c+ 07:58:00 07:59:00

146.K9b-9c 07:58:00 07:59:00
147.B3c-5a+ 07:58:00 07:59:00
148.R*7h 07:58:00 07:59:00
149.G7ix7h 07:58:00 07:59:00
150.G6gx7h 07:58:00 07:59:00
151.K8h-9h 07:58:00 07:59:00
Resigns 07:58:00 07:59:00
Habu could have tried 152.G8h here, because 153.Kx8h?? Rx6h+ leads to
mate. However, Sato would undoubtedly have played 153.K9g, after which
there is no mate. On the other hand, black has the multiple mating
threats R*8c and N*8e Px8e S*8d and there is no way to defend against
this. A fine win by Sato, even though he got a little scare in the middle
of it. He is still 3-1 down and needs to win all the remaining games,
so his situation has only improved slightly.
