Looking for a better line 25/50 FR

[oldfashiond]

Ive played pretty standard TAG so far, but opponent loves to play pots w me as ive played him super agg lots of other times, stacking him often. he's a bit of a donk, def capable of idiotic moves. not sure wether i pref to check or bet the turn here. i checked in hopes of not getting stuck in a huge pot here, but i dont know if it achieves that. any suggestions? and as played what do you do facing his turn bet?
