Check back or bet on the river?

Your turn bet is a bit small. It gives all the draws pretty good odds to call. We have a blocker so A2 is not so likely. Also 6x has a straight now. I think checking back and betting smallish are both valid options since villain often calls with worse hands. Don't know which one is more +ev.

Vs probably fish I would bet like 1/3 if he didn´t look very agro (I don´t want to face a raise). But I have no problem with x/b. Vs better opponent I like x/b

As played I would use smaller sizing F (our hand is not so strong and we don´t need to care about balance vs this opponent) and bigger on the turn.

I think that opening this hand from CO is a bit too wide.
I like the idea of making a small bet on river.

I also wouldn't open this hand from the CO. As played, a bigger bet on the turn is better, imo, and I would check/back the river because I don't see many worse hands calling and we will hate our life if he decided to raise.

Villain is fishy, he can Call with a lot worse, probably would've lead if he had hit OESD. Valuebetting this.

i would bet pot on the turn - max value and you can look like you have alot of overcard draws
