JJ overpair OOP, raised on flop

villain is 22/8/8.5 over 130 hands. no reads. i havent seen him raise a FD yet, but i havent really been playing attention to it. If had more like 20/16/8 stats i would shove because hes raising a FD here alot, but with his weirish stats im not so sure he knows its good to do that. Hes limp called a few times but i cant remembet him doing it UTG.

I can't see not getting it in here vs someone this aggro.

yeah get it in.

also if he was 20/16 instead this would be a way worse spot because his range would be more sets. but when hes 20/8 theres a lot more suited cards hes limping with.
