Villian has played only one hand thus far, making a big raise preflop, didn't showdown. I considered folded. Anyone calling here? Pushing?

I don't want to fold, calling seems silly, so I push. Can I, should I get away here? Thoughts on the action?

Hero decides exactly how good his hand is in the initial act and either moves all-in, or calls to hit a set.
