Hero ???

Villian is a 20/16/3, solid TAG, haven't seen any crazy plays from him so I don't have any special notes/reads.

PREFLOP: standard

FLOP: I get check raised, but I call since I have position, 2nd pair and open ended straight draw. I put the villian on AQs, AJs, ATs, KQs, KJs, KTs, QTs, JTs, T9s, J9s, 98s, A7, 99, 88, 66, 55. Maybe but less likely a slowplayed TT+ or AKs.

TURN: he bets 25 into 40, pretty weak bet. I was deciding here between shoving or just calling. I should probably shove or fold here.

RIVER: He pushes the rest of his stack: $50 into a $90 pot. Tough decision time.

On turn stove says I am 70%:30% vs his range, but I am not sure if he is capable of 3 barelling with everything that I beat on the river.
