Hello sykora808,
Welcome to the NL BSS Hand Evaluation Forum! Hopefully we will see more hands from you in the future, so we will be able to help you fix your leaks and as well help move up the limits. We will be waiting for the next hands and till that good luck on tables!
About the hand:
I don't like 3betting on river anymore, while we don't hold the nuts and it was basically just a freeplay pot. I would rather just Call his raise and be happy if we are ahead.
Best regards.
