Does God have free will?
Yes. Analogically speaking, of course, but yes.

Can God sin? Can He violate His Holy Nature?

Heh heh heh

I believe in response to YOUR "pawn to King's Bishop 4" my answer is
God does not "have the ability" to sin, because sinning is not an ability but a disability, a defect.

(Hint: I'm doing a different understanding of "Freedom" and "Free will.")
