[PLO2] overpair vs aggressive villain in a very connected board

even against an aggressive CO I cant find a call OTF. his range fits this flop much better than ours. unless you have specific notes, let them overplay their hands, be patient and get his stack when the times has come. If he shows mad maniac aggressive plays you can note them and adjust accordingly.

On the flop you can easily fold. He never donks pot with total air, so he has something. And his "something" range is beating you. In the best case scenario you have 40-50% equity.

You should raise the flop to stack-off or Fold if you assume his pot-donk is unusual and showing a lot of strength (he will not have a strong hand like 2pair+ often though, so he is not allowed to donk the flop frequently, it is more likely he is weak and will stack off a hand like oesd, overpair or just pair+sv so I'd go allin).

I dont understand what you want to achieve with a call, if he is aggressive he will follow up aggression on further streets, you have only 1 backdoor and your hand will never ever improve to sth better.
