[White "Habu Yoshiharu, Meijin"]
[Event "69th Meijin-sen, Game 3"]

1.P7g-7f     00:00:00  00:00:00
2.P3c-3d     00:00:00  00:01:00

4.P5c-5d     00:02:00  00:03:00

In the first game Habu played 4.P8d here and the game developed into one 
of the latest Yokofudori variations. Habu plays more or less anything, and 
this time he gives the Nakabisha a try, also a very popular opening.

15.S3g-4f    00:19:00  00:57:00

Moriuchi doesn't shy away from the latest fashion and plays the ultra-quick 
attack S3g-4f with the king still on 6h.

The sealed move.

Diagram 1

49.B8h-9g!   04:55:00  06:11:00

Very positive way of playing by Moriuchi. The obvious defense here is 49.P*4h, 
but Moriuchi commented after the game that he didn't really want to drop a 
pawn here. The rest of this game shows that he was correct about his feeling 
that B9g was the right move here.

50.R4b-4d?!  04:55:00  06:51:00

Habu thought for 40 minutes before playing this move, but it is questionable 
if this was the right way to play here. Of course, white wants to play 50.P4g+ 
here, but after Bx4b+ Gx4b Gx4g Bx6f the problem is that because white has removed 
the pawn on the 6th file, black give a huge boost to a future attack because a 
pawn drop on 6b is now possible. Habu didn't like that and decided to play 50.R4d 
instead, but this gives black the opportunity to drop the rook in the enemy camp 
first. It seems that white is already in trouble here.

51.R3dx4d    05:06:00  06:51:00
52.B3cx4d    05:06:00  06:51:00
53.R*4a      05:07:00  06:51:00
54.G3b-3c!   05:07:00  06:54:00

Diagram 2

Actually a very good way to fight back. It is clear that white would be better 
off with the gold on 5b than on 3b, but the incomplete Mino castle is not as 
weak as a it seems. After 54.G3c, it is not so easy to find a good way to 
continue for black.

55.N2i-3g!   07:14:00  06:54:00

Played after 2 hours and 7 minutes, which is an illustration of the difficulties 
that Habu has put into the position. In the press room 55.P*3d Gx3d B4b+ was 
analyzed deeply, but no position was found that was clearly better for black. 
Moriuchi himself admitted after the game that he suddenly had no idea how to 
continue in this position. Often thinking for a long time is counter-productive, 
leading to bad decisions, but this is an exception. The two hours were well spent, 
because Moriuchi probably found the only way to keep the pressure on Habu. White 
cannot allow this knight to enter the attack, so Habu is forced to attack.

56.R*4h?     07:14:00  07:14:00

Diagram 3

This is probably the wrong square to drop the rook. Better is either 56.R*2g S*5e 
P4g+ Gx4g B7a Rx2a+ P*3f Gx3f R2h+ or 56.R*4i S*5h Rx1i+ N4e G3d N5c+ although 
black seems to be better in both cases. Still, Habu admitted that especially 56.R*2g 
was probably better than 56.R*4h.

57.S*5h!     07:19:00  07:14:00

Strong defense. Now the problem with 56.R*4h becomes clear. The obvious move here 
is 58.S*3f, threatening P*4g next. However, with the rook on 4h, even if white 
promotes the pawn on 4g, black can answer +Px5g next with Sx5g or +Px5h next with 
G5g-5h. In both cases the rook on 4h is attacked and has to move. This all just 
gives black too much time to attack.

58.P*5b      07:19:00  07:51:00
59.P*4c      07:55:00  07:51:00
60.R4h-2h+   07:55:00  08:14:00
61.P4c-4b+   07:56:00  08:14:00
62.S*4h      07:56:00  08:14:00

Looks bad and in the press room 62.N*4f was analyzed here. If black responds with 
the natural 63.S5-h6g then 64.Bx5e Px5e G*5h suddenly gives white a strong attack. 
However, after 63.S4g it seems white cannot make the attack work. For example, 
64.Bx5e Px5e G*5h +Px5b Gx6i Kx6i G*5h K7h Gx6h K7g G7h K6g and the black king 
escapes.

63.G5gx4f    08:02:00  08:14:00
64.S4hx3g=   08:02:00  08:15:00
65.G4f-5e    08:04:00  08:15:00
66.S3g-4h+   08:04:00  08:17:00
67.S5h-6g    08:10:00  08:17:00
68.B4d-2f    08:10:00  08:20:00
69.+P4b-5a   08:12:00  08:20:00
70.G6a-7a    08:12:00  08:20:00
71.+P5ax5b   08:16:00  08:20:00
72.N*6a      08:16:00  08:21:00
73.R4a-4f+!  08:26:00  08:21:00

Diagram 4

The decisive move. This forces the white bishop from the all-important diagonal 
7a-1g. There it not only defends the gold on 7a, but also the vital drop squares 
on 6b and 5c.

74.B2f-3g+   08:26:00  08:25:00
75.+R4f-4b   08:31:00  08:25:00
76.+B3g-2f   08:31:00  08:25:00

White has no choice but to move back the promoted bishop to the vital diagonal, 
but the difference between an unpromoted rook on 4a or a promoted one on 4b is 
too big.

77.P*4i      08:37:00  08:25:00
78.+S4h-5i   08:37:00  08:29:00
79.G6ix5i    08:42:00  08:29:00
80.+B2fx5i   08:42:00  08:29:00
81.P4i-4h    08:42:00  08:29:00
82.+B5ix6h   08:42:00  08:44:00
83.K7hx6h    08:42:00  08:44:00
84.G3c-3b    08:42:00  08:44:00
85.+R4bx3b   08:45:00  08:44:00
86.+R2hx4h   08:45:00  08:46:00
87.K6h-7g    08:45:00  08:46:00
88.G*5g      08:45:00  08:59:00
89.S*6b      08:54:00  08:59:00
90.G5gx6g    08:54:00  08:59:00
91.K7gx6g    08:54:00  08:59:00
Resigns      08:54:00  08:59:00

Final Diagram

No mate against the black king, but a simple mating threat against the white 
king after Sx7a= next. There is no defense: for example, 92.Gx6b is also mate 
after 93.B*7a Kx7a +Px6b etc. Therefore Habu resigned here. Another great win 
for Moriuchi who now is one win away from regaining the Meijin title he lost 
to Habu in 2008. Winning four games in a row is not as impossible as it was a few 
years ago, but considering that Habu is being outplayed by Moriuchi in the match 
so far, a comeback seems unlikely.
