2.P8c-8d     00:00:00  00:06:00

5.P5f-5e     00:20:00  00:43:00

6.S7a-6b     00:20:00  00:44:00

7.R2h-5h     00:25:00  00:44:00



After Habu's Quick Ishida in game 1, again a furibisha opening. 

This time Tanigawa plays the Gokigen Nakabisha.



8.K5a-4b     00:25:00  00:49:00

9.K5i-4h     00:30:00  00:49:00

10.K4b-3b    00:30:00  00:55:00

11.K4h-3h    00:32:00  00:55:00

12.S3a-4b    00:32:00  00:59:00

13.B8h-7g    00:55:00  00:59:00

14.P6c-6d    00:55:00  01:22:00

15.S7i-6h    01:04:00  01:22:00

16.S6b-6c    01:04:00  01:25:00

17.K3h-2h    01:10:00  01:25:00

18.G6a-5b    01:10:00  01:35:00

19.S3i-3h    01:23:00  01:35:00

20.S4b-3c    01:23:00  02:02:00



Looks like a questionable move, but this makes it difficult for 

black to develop his pieces by P5d, because this no longer threatens 

the exchange of the bishops.



21.S6h-5g    02:05:00  02:02:00

22.S6c-7d    02:05:00  02:44:00



After 20.S3c another strange looking silver move, but this move aims 

at the undefende pawn on 7f, so black can not take this lightly. 

This use of the silver has been played before, but in this game 

neither side has pushed the edge pawn on the king side, which makes 

this exact position a first. From this game it is hard to judge if 

this is a significant difference.



23.S5g-5f    02:37:00  02:44:00

24.S7d-8e!?  02:37:00  03:11:00



The start of a risky silver attack. Even Habu admitted after the game 

that he had not idea if this was good or bad.



25.P7f-7e    02:45:00  03:11:00

26.S8e-7f    02:45:00  04:03:00

27.B7g-6h    02:48:00  04:03:00

28.S7fx8g=   02:48:00  04:20:00



Diagram 1



White has won a pawn, but the silver on 8g is completely out of play. 

Furthermore, it will take quite a lot of time to activate this silver, 

because S7f+ can be answered by R7h, after which the silver has to go 

back to 8g. White has to wait until black plays 6f before S7f+ is 

possible. All of the commentators in the press room and Tanigawa 

himself thought that white's silver attack was an overplay and that 

black could get the advantage by opening the game while the silver 

is still on 8g. 



29.B6h-4f    03:24:00  04:20:00



The sealed move.



30.S3c-4d    03:24:00  04:25:00

31.P7e-7d    04:03:00  04:25:00

32.G5b-6c    04:03:00  04:51:00

33.P7dx7c+   04:25:00  04:51:00

34.N8ax7c    04:25:00  04:52:00

35.P6g-6f    04:26:00  04:52:00

36.S8g-7f+   04:26:00  04:55:00



Diagram 2



37.R5h-6h    05:05:00  04:55:00



Here Tanigawa realized that things were not that simple. Black seems 

to have all kinds of good moves here, but none of them work: 1) 37.R7h 

+Sx6f P*7d P*7b wins a knight, but leaves black without pawns; 

2) 37.P6e Nx6e P5d Gx5d and black has no continuation; 3) 37.P5d Px5d 

P6e (changing the order of the previous variation) is met by P5e Sx5e 

P*5g Rx5g Nx6e R5f Sx5e Bx5e Bx5e Rx5e B*6f and after the rook moves, 

white has N5g=. In the end, Tanigawa decided to admit strategic defeat 

and play the quiet 37.R6h, patiently waiting for a chance, which seems 

likely to come with several weaknesses in the white camp.

54.R*7i!!    06:43:00  06:36:00



Habu magic. Everybody (including Tanigawa) expected 54.Bx9a+ after which 

black has fighting chances. Tanigawa had planned 55.P*7d and if play 

continues 56.L*4d P6c+ Gx6c Px7c+ Lx4f +Px6c the position is unclear. 

Habu decides to return the material he gained to play L*4d without 

white getting a chance to attack the head of the knight. Brilliant 

judgment that basically ends this game. White never gets a decent 

counter attack going.

Another blow. This promoted bishop picks up a silver and controls the board.

Final Diagram



The material difference in this position is small, but white has no decent 

attacking moves (for example, N*1e is answered by P*6c). On the other hand, 

black can choose from moves like P5f and R*8h, which will quickly destroy 

the black position. Tanigawa took three minutes before resigning, but saw 

no point in playing any further. After the game he admitted that he had no 

idea what had gone wrong and that probably the position at the end of the 

first day was already bad for black.
