What do you do here? His line looks really strange. If he has the straight why is he overbetting so much? I can't see much hands he calls my bet on the turn with and then makes a straight. Cause I can't really see him calling here with 5x or 10x and a gutshot, he could have 45 though or something like 107, 103, 57, 53, or even a set though I think he would raise with a set on the turn. His line looks a lot like a busted flush draw to me. Comments on all streets welcome. Thanks

45?

I don't mind a bet OOP on the flop. I'm folding two overs here against a flop that's likely to hit the blinds.

As played, if you don't bet the river you are begging someone to take it away.

I called and villain had k2 of diamonds... Don't ask me what he was thinking lol
