NL200: Backdoor in to 2 pair in blind battle vs 2+2er

[Mr_Donktastic]

Villain is a taggy 2+2er. Haven't played with him in a while but he is pretty tight preflop and very aggro postflop, esp vs me it seems. Very capable of floating, making big bluffs, etc but not spewy. He prob views me as about the same.

This hand happened first, maybe one or two orbits before.
