Prefectural elimination tournaments of amature Meijin championship

I participated Prefectural elimination tournaments of armature Meijin championship last weekend.
There are strong players in Saitama prefecture.

This is my first game (I'm sente).
The strategy of gote have been often seen recently.
Against that, my S-56 is challenging movement. Usually, sente moves R-78 in spite of S-56.

After that, the game proceeded to mutual attacking with P-75, P-65, Bx77+, Kx77, S-53, Px75, P-86....
At final, I was defeated.
After all, S-56 may be risky... I will consult again.
