30.L9a-9c    02:21:00  03:37:00

The same opening as in the second game. Abe's way of thinking seems to 
be: "If I can't win with my favourite opening, I will never take the 
Ryu-O title". Habu again answers the Morishita system with the Suzeme 
Sashi (Spearing the Sparrow). The general opinion among professionals 
is that the Morishita System (S3g-S4f-N3g without P2f) has weaknesses 
against the Suzume Sashi. As a result, the Morishita System has almost 
disappeared from the professional scene.

31.S3g-4f    02:45:00  03:37:00
32.R8b-9b    02:45:00  03:39:00
33.P5f-5e    02:59:00  03:39:00
34.P5dx5e    02:59:00  03:46:00
35.S4fx5e    02:59:00  03:46:00

Abe builds up the pressure in the centre to balance the white edge 
attack. In the second game he never really got his attack into gear.

36.G5b-4c!?  02:59:00  03:46:00

Diagram 1

Meijin Moriuchi found this one of the most interesting moves in this 
game. 36.N7c or 36.P9f are the usual ways for white to play this 
position. 36.G5b-4c is difficult to play, as it gives black another 
target for his attack in the centre and also weakens the position of 
the white king. In general, it is not a good idea to play the gold 
to 4c in the Susume sashi when the king is still on 4a.

37.R2h-5h    03:25:00  03:46:00

The alternative is 37.K8h, but Abe didn't like 38.P*5d S4f P7e Px7e 
Bx7e. 37.R5h is also not without risks, as there is always the 
potential silver drop on 6i.

38.P9e-9f    03:25:00  03:49:00

Diagram 2

39.P9gx9f?!  03:48:00  03:49:00

The sealed move and everyone thought that this was an easy choice. 
However, black could have played the strong 39.S5d! here. White has 
three ways to respond to this: 1) 40.B6d, 2) 40.Gx5d and 3) 40.Px9g+
but black seems to get a good position in all three cases: 1) 40.B6d 
Sx4c+ Gx4c B4f Bx4f Px4f B*4g R5g Bx2i+ B*8c; 2) 40.Gx5d Rx5d S5c 
Rx7d S*7c G*8c; 3) 40.Px9g+ Sx4c+ Gx4c G*8c.

40.L9cx9f    03:48:00  03:51:00
41.L9ix9f    04:59:00  03:51:00
42.R9bx9f    04:59:00  03:51:00
43.P*9g      04:59:00  03:51:00
44.R9f-9b    04:59:00  03:56:00

White has succeeded in exchanging lances, which is one of the primary 
goals of the white attack. Habu has the upper hand in this position.

45.K7i-8h    05:01:00  03:56:00
46.N8a-7c    05:01:00  04:36:00
47.S7g-8f    05:06:00  04:36:00
48.L*5a      05:06:00  04:51:00
49.P*5d      05:19:00  04:51:00
50.P*5c      05:19:00  04:51:00
51.P5dx5c+   06:04:00  04:51:00
52.S6bx5c    06:04:00  04:52:00
53.B6h-4f    06:04:00  04:52:00

Abe realises he is in trouble and tries to confuse the position.

54.N7c-8e    06:04:00  05:42:00

Not 54.P*5d because of 55.Sx4d S5cx4d Bx7c+.

55.P6f-6e    06:05:00  05:42:00
56.P4d-4e    06:05:00  05:43:00
57.B4f-5g    06:07:00  05:43:00
58.S5c-4d    06:07:00  05:51:00
59.B5gx8d    06:09:00  05:51:00

Abe is already thinking about making an entering king here. It seems 
to be the only way for him to have a chance of winning this game.

Diagram 3

White has a big material advantage, but it is very hard to stop the 
black king from entering. After this mistake, white can no longer avoid 
this. Better was 86.Bx6d and it is still very much in doubt whether 
the black king can find a safe haven in the white camp.

87.P7f-7e    07:26:00  07:30:00
88.K4a-3a    07:26:00  07:32:00
89.P6dx6c+   07:35:00  07:32:00
90.+R9dx7d   07:35:00  07:37:00
91.P7ex7d    07:35:00  07:37:00
92.N*7e      07:35:00  07:37:00
93.K7g-7f    07:35:00  07:37:00
94.N7ex8g+   07:35:00  07:39:00
95.K7f-8e    07:35:00  07:39:00
96.+N8gx8h   07:35:00  07:45:00
97.P7d-7c+   07:35:00  07:45:00

Abe has abandoned all his pieces to make two tokins in the white 
position that will give his king enough support to walk to the 
other side of the board.

98.K3a-2b    07:35:00  07:46:00
99.R*9a      07:39:00  07:46:00

Now the black king is safe to enter. Habu has no chance to mate the 
black king, so his only option is to make an entering king himself 
and win on material.

100.B*3i     07:39:00  07:46:00

Threatens both G*8g and G*2h. Getting the black rook on 1h means five 
extra points in case of mutual entering kings.

127.G7f-7e?  07:54:00  07:56:00

Diagram 4

With his king safe, black has gotten very good winning chances and it 
is time for black to find a way to attack the white king. Here Abe 
misses a good chance to combine attack and defence. After 127.+Px9b 
+Rx9b +P8b +R9f K8b followed by +R7b black's attack is very strong. 
It is highly unlikely that the white king will be able to escape up 
the board. Now the outcome of the game is again unclear: an incredible 
mud fight is ahead.

Diagram 5

Good move. The simple 163.Rx2a+ Kx2a Lx2c+ gives white a later Rx2i+ 
with defence and the bishop on 1h is still working well.

164.+B1hx2h  07:58:00  07:58:00

Now Rx2i+ no longer defends and the bishop is no longer on an important 
diagonal.

Diagram 6

Habu has not been able to find a way to make an entering king and black 
has again a winning position. Here Abe missed the simple 191.G*1c Gx1c 
B*3b, threatening mate and the rook. The outcome of the game doesn't 
change, but now there are still a lot of moves left to play.

Final Diagram

Finally, this historical fight ends with Abe winning and levelling the 
match at 2-2. The final position will be printed many times. It almost 
looks like a tsume shogi problem with only 14 pieces on the board. There 
are so many pieces in hand that the players dropped them numerous times 
from the komadai during the post-mortem analysis. A record-breaking 
game as it was the longest game ever to be played in the Ryu-O, both 
in number of moves (previous record 203 moves) and in time (the game 
finished at 20:59 in the evening). Abe will not care much about these 
facts, but more about getting completely back in this match after being 
2-0 down. The next game will be pivotal...
