55.S4ex3d 04:08:00 04:07:00
A Yagura opening for the third time in this match. Habu sacrifices a silver for
attack, but the position remains unclear for a very long time.

87.P*3c! 04:27:00 04:33:00
Black ignores the attack on the rook and goes straight for the focal point pawn
drop.
88.G3bx3c 04:27:00 04:35:00
White cannot take the rook here, because after 88.Bx1h+ Px3b+ Kx3b G*4d S*3c
Gx5c Sx5c B*7a R5b Nx3c+ Sx3c S*6a is good for black.
89.P1d-1c+ 04:29:00 04:35:00
90.K2b-3b 04:29:00 04:35:00
Not 90.Px1c because of 91.Lx1c+ Lx1c Nx1c+ Sx1c B*1a and black wins. After
90.K3b, black has successfully broken through, and Watanabe was unhappy because
counter attacking moves like P8f or Nx6e never materialize. However, Habu also
wasn't so sure about his position because the white king can run to the other
side of the board and it is not use to catch it. The position still seems
unclear here.

118.+B8b-8c? 04:56:00 04:58:00
Only here Watanabe makes the decisive mistake. As Habu pointed out after the
game, white should have played 118.Sx7h+ Gx7h G*6b R5a+ B*5f here which aims
at another sennichite after G*7i Bx7h+ Gx7h G*6g G*6g etc. The post-mortem
analysis seemed to indicate that black can avoid this sennichite variation
and still survive the white attack, but the variations were very complicated
and it would have been very hard for black to find the correct defense in the
middle of the night with very little time remaining.

126.B*5f 04:59:00 04:59:00
127.S*6g 04:59:00 04:59:00
Now black has managed to build a strong silver Yagura castle. This gives him
the time to get the gold on 3d to join the attack, which decides the game.

147.B*8d 04:59:00 04:59:00
Resigns 04:59:00 04:59:00
Mate after 147.Gx8d +Rx8d Kx8d G*7d etc. or 147.K8b Bx7c+ Nx7c G*8c etc. or
147.K9b G*9c Nx9c Bx9c+ etc. so Watanabe resigned here. At 2:02 in the morning
the fourth game of this Oza match is finally decided. Habu wins the game and
the match, taking back the Oza title he lost to Watanabe last year. This takes
his total title tally to 83, and also his number of Oza crowns to 20. Winning
the same title 20 times ties another Oyama record (Meijin titles in Oyama's case),
so this is also a new entry in the record books for Habu. For Watanabe this loss
is a new experience: he lost a title defense match for the first time in his
career. With the Ryu-O match against Maruyama coming up, it will be interesting
to see how he deals with such a setback.
