200 hu...sexy river overbet shove?

[ty2472004]

Villian in question is solid but not spectacular. I've been extra bluffy this session, and he's been looking me up lights. I think he'll view this as the nuts or air, and since it's pretty doubtful I have a really strong hand, I'm pretty certain I'll get looked up by any 8 (his most plausible holding) and maybe even less. I would love to hear some advice/criticism on this hand.
