(diagram 1)

2.P-2f G-3b
3.P-2e Bx8h+
4.Sx8h S-2b
5.S-3h S-3c
6.P-3f S-6b
7.S-3g P-6d
8.S-4f S-6c
9.S-7g S-5d
10.K-6h P-8d
11.G-7h P-8e
(diagram 1)



In the diagram 1 , Sente already has difficulty to attack Gote's camp or advanced his own camp . If Sente don't start attacking , Gote will push his Pawn ; 4d --> 4e , and Sente must back his Silver 3g .

Then Sente start attacking with P-3e , and game will advance like following moves .

(diagram 2)

12. P-3e Px3e
13. Sx3e P-8f!
14. Px8f P*8e!
15. Px8e Rx8e
(diagram 2)










In diagram 2 , Gote gets a fork on 3e Silver and 8i Knight . Sente can't protect both piecies and Sente will get bad position .


Sente can avoid this fork by 15.P-2d instead of 15.Px8e . But in this line , Sente's camp will advance bad formation P-8h . I will show one example moves below , and Gote will get advantage .
