MP is a reg 22/17, CB 51 (over 514 hands)
CO is a rec 45/18 over 62 hands

I wonder whether I wanna raise to the initial bet, but I dont think the reg is happy to call his AK,AQ,AJ without any backdoors, so decided to call since he would be prob cold calling his overpairs to my raise anyway.
After he raises, I believe its more less some overpair.. and potentially FDs or sets. But 55-66 might not be in his raising range pre.. but given his pfr it might be actually, however, I dont think he would check 55-66 on this board esp. with the fish involved.. TT makes some sense.. but folding out JJ-AA and running into TT is okay for us due to generated fold equity..

I really dont like just calling, because I feel like my hand is just too faced up to a FDs.. therefore most regs might be able to play pretty precisely vs my defined range..
Blocking 7h8h,8h9h isnt best though..
Maybe not jamming, but make it smaller to invite his FDs to call? I think that overpairs are either calling or folding pretty inelastically (no matter if I use 3x sizing or jam.. maybe not.. not sure on this one though, because some might call with intention to fold on flushy turns..)
