Its crypto so the converter doesnt work [img]/images/graemlins/frown.gif[/img] Formatted it the best I could.

Should I have 3bet PF? I was OOP throughout the hand which is why I didnt

I c/r the flop since his high PFR meant that it wasnt necessarily a PP or AK which were all that beat me. I carried on betting the turn to try and take down the pot. Was going to fold to a raise at any time (easy given his aggression). Check/fold turn? river?
