200 NL big draw vs big lag

[pleyya]

Im still quite new to No-limit and wasnt sure about this one.
Preflop call might have been a little light..Raiser is about 48/16/3 so quite aggro and he calls to much. UTG is LP about 50/2.

He was quite aggro so i thought he had a wide range however i didnt expect him to fold TPTK or overpair to a push. Even with low fold equity i should push this right? Although i am a slight underdog to an overpair.
