Habu rarely plays this strategy, so this was probably meant to surprise Fukaura, 
adding a little pressure to the limited time available due to the replay of the 
sennichite game.

Diagram 1

For a long time, it seemed like this game might also end in sennichite as it is 
difficult for both sides to open the game. However, Habu isn't known for playing 
sennichite games often and it was felt that even though he has the white pieces, 
he would take every reasonable opportunity to open the game. He does that here, 
but it is hard to say that 50.P4e is the right move here. At first sight, it looks 
like a complete overplay. As we will see, white actually has some way to keep the 
attack going. Still, arbiter Akutsu thought that because black has pushed the edge 
pawn to 9e, opening up the game here was a little too dangerous and after the game 
Habu admitted as much.

68.P*4g      03:04:00  02:56:00

White has promoted the bishop and put the gold in a bad spot on 3f at no loss of 
material. It seems like he is doing well, but black can now counter this with a 
bishop promotion of his own and the position is unclear.

78.+B3h-4g?  03:11:00  03:09:00

A mistake that gives black the upper hand. Correct would have been 78.+P5h P*5i +P5g 
and the tokin is closer to the black king, which is important in a game where neither 
player has enough firepower to start a devastating attack. Also, the square 5f is 
now perfect for the promoted bishop.

84.R6ax4a    03:15:00  03:13:00
85.+B6fx4h   03:15:00  03:13:00

Fukaura has picked off the black tokin and now is a silver for a knight up. A clear 
advantage, which is only slightly affected by the bad gold on 3f. The problem is that 
none of the black pieces is anywhere close to the white king, which makes winning 
from here will take a lot of work.

Diagram 3

It seems like black is putting a lot of pressure on the white position, but Habu 
finds a way to fight back. Taking the silver on 7f and using this to fuel an attack 
on the 6th file is keeping the game close. We have already played 114 moves in this 
replay of game 2, but the end is nowhere near. Akutsu actually expected the game to 
take more than 200 moves to finish.

Good move. Not only bringing the eye sore gold on 3f into play, but even more 
importantly opening 3f for a bishop that will be pointing straight into the white 
position.

149.S*7g     03:58:00  03:54:00

This move shows a lot of restraint. Especially under time pressure most players 
would have played N*6d here, which is a mating threat. Fukaura decides that it 
is not strong enough and that he needs to strengthen his defense to win.

177.R3ax6a+? 03:59:00  03:59:00

In byoyomi and after 177 moves, Fukaura makes the mistake that will cost him the 
game. He could have won if he had played 177.G*7b here. This is threatening mate 
with Gx8a next and black can also take the silver on 8b next, so there is no proper 
defense. Important is that 178.Gx7b Rx8a+ Kx8a R*6a leads to mate. On the other hand, 
the black king cannot be mated: 178.S*7i K7g B*9i Kx7f G*6f K8e P8d Kx8d S9c Kx9e 
S9d K8d and there is only mate with a pawn drop. Kind of amazing that such a long 
battle could have been decided by such a tiny margin.

180.B7f-5d   03:59:00  03:59:00

This defends against the mating threat Rx8a+ and threatens mate at the same time.

Final Diagram

The black king will be mated after +R8g but there is no proper defense. Also, there 
is clearly no mate against the white king, so Fukaura resigned here. Tough for 
Fukaura to go 2-0 down after playing so well for so long. Still, Habu always managed 
to keep the game close enough that one slight mistake could turn the tables in his 
favor. Great effort by both players, but Fukaura now needs to win game tree to 
avoid being swept two years in a row by Habu.
