10.S3a-4b 0/6 5/18
Both players are experts in the Yagura, especially Sato who has written a
number of very good books on this extremely complicated strategy. This double
Yagura was therefore expected. However, white's results have not been good
recently and it was interesting to see what Sato would play.

21.S6h-7g 7/65 0/89
22.S5c-6d 0/65 5/94
This quick attacking strategy must have surprised Habu. It is not really Sato's
style to attack this early. At professional level, it is a major gamble to
attack without the king being safe. Sato: "With white I thought I had
to go for it". We are still before lunch on the first day of a two day game.
Having already such a complicated position is very rare.

26.P7ex7f 0/167 7/154
27.G6gx7f 1/168 0/154
Habu took only one minute for this move, but it took Sato completely by
surprise. "I had only thought about 27.Sx7f and 27.Px6d". Usually it is not
a good place for the gold to be on 7f, but Habu is aiming at putting pressure
on the left side of the position.

49.P9g-9f 1/295 0/293
50.G6a-5a? 0/295 15/308
Not good. Sato was worried about P4f followed by P3f and decided to improve
the position of his king instead of answering the edge pawn. Habu never pushes
the pawns on 3g and 3f though... 50.P9d was necessary to keep in the game.
51.P9f-9e 16/311 0/308
52.G5a-4b 0/311 2/310
53.P8g-8f! 7/318 0/310
Great move that was overlooked by Sato and probably by everybody else except
Habu. Pushing the pawn in front of the king is usually the last thing one
wants to do, but Habu judges that white's pieces have all gone to the right
side of the board, while his pieces are all on the left side. There he wants
to attack. Habu's strategic brilliance is clear from this game.

61.S5g-6h 0/360 0/373
62.S4d-5e?! 0/360 8/381
Better 62.S4d-4e to open the bishop diagonal. Then if 63.S6h-7g S5e K8g then
P5g+ Gx5g B1c is bad for black. However, after 63.S8f-7g S5e P7d P*7e Gx7e
P5g+ Gx5g S4e-5f P7c+ Habu still seems to be winning.
63.P7e-7d 10/370 0/381
64.P5f-5g+ 0/370 47/428
No choice. If white defends with 64.P*7b to aim for the same position as in
the comments above, black plays 65.S7e S5e G6g-7g which is much better for
black. It is interesting that in this game control of the board is more
important than the position of the king. Habu's king is obviously not in the
perfect castle shape, but because he controls the left side of the board,
Sato has no chance to attack. Habu's comments: "This Shogi looks like Go,
doesn't it".
65.G6gx5g 22/392 0/428
66.S5e-5f 0/392 0/428
67.G5gx5f 1/393 0/428
68.B2bx9i+ 0/393 0/428
69.S*8h! 2/395 0/428
Subtle move that decides the game. If black plays 69.+B8h immediately, white
has still chances after 70.+Bx8h Kx8h, which leaves all the black generals
undefended or 70.+Bx8i Kx8i L*8g which is also nasty.
70.+B9i-9h 0/395 2/430
71.S8h-8g 2/397 0/430
72.+B9h-9i 0/397 0/430
73.B7i-8h 0/397 0/430
74.+B9ix8h 0/397 18/448
75.K7hx8h 0/397 0/448
The difference with the bishop exchange in the variation before is clear. All
generals are now defended and white has no attack. Comment in the press room:
"Perhaps 30% of the professionals would have resigned here". Sato decides
to try it a little longer, but I do not think Habu has lost a winning endgame
position since he was three years old.

Time: 07:32:00 07:47:00
A surprisingly one-sided game between these two. Still, nothing's lost, since
Sato will have black in game two. That game he has to win.
