Villain stats VP28/PFR19/3B14

Preflop - standard open-raise

Flop - Polarized sizing as villain only fold to 35% flop c-bets, and i have a strong 2 pair hand

Turn - Definitely still think we are best, and he could still have these gut-shots that he'll be calling down no matter the price, any ace he will call again and some kings i think. So i decided to fire another polarized c-bet.

He raised the turn, but he flat called from SB. So i don't think he has many hands that beats us here. Maybe 99, and maybe he called with 66 vs the polarized bet on flop which this play probably is capable to. But i decided to call with my strong 2 pair holding. With his high 3-bet percentage i don't believe he will slowroll with AK, KK and AA here.

Should i just jam over his raise here on the turn? Or is it fine as played?

River - The third spade arrives and it's a J, but i really don't see a lot of flushes in his range here, maybe some QJs, JTs, QTs? But this river completes all his bluffs right? So if i wasn't beat on the turn, i almost certainly is on river, right?
