Notes on villian:
hadnt seen him raise to this sizing at all although may have missed it as i am multi tabling. It made me suspicious and he has shown to be a relatively weak player so i viewed it as him wanting value form the bb(me) if i call. i raised and he flats with no timing tells.
the check raise is obviously susspect but i figured im still at least flipping against his range, i don't see him raising to such a strange size with his lower and middle pairs but obviously could be wrong.
i opted to re raise all in, which in hindsight, calling is the far better option because if the board pairs or the flush hits i can definitely find a fold to more aggression.
thoughts concerns?

villain is a general fish not much else to it, a mistake is definitely checking back flop, i think i should definitely just take a bet/bet/bet line.
as played against him i dont think i can fold river. he could be overvaluing any ace or two pair and im getting 2.7:1
