It is necessary to select interposing piece accurately for increasing win ratio.
What do you respond the Check R*5h in figure. 1?
figure. 1
If you move S*4h or B:4h, then G*2h, K-4i (if Kx2h, you are mated by Rx4h+, G*3h, S*3i), Rx6h+ (figure. 2).
In figure. 2, my King are Brinkmake (you can't prevent both mate G*5h and G*3h simultaneously).
figure. 2
So R*4h is accurate interposing piece in figure. 1 (figure. 3).
By interpose Rook (R4h instead of S4h in figure. 2), you become to be able to take Rx4h if the game will proceed just like figure. 2.
figure. 3
From figure. 3 the real game proceeded as Gx2h, K-4i, Rx4h+, Kx4h, R*3h, K-5g, G*6f, Kx6f, +R-6h, P*6g (figure. 4).
I succeeded to stop the opponent's attack. After that I counterattacked and won.

The entire Kifu is following. In fact, I failed piece-building in opening, then the opponent attacked and I maneged to defended.
