How did I play this? Was it okay to call on the turn? I felt there was a decent chance he had two pair on the flop, which gave me some outs. Did I play too aggressive on the river? Props to anyone that can guess what was Villains hand. [img]/images/graemlins/grin.gif[/img]

Most people said I shouldve called the turn, but I didnt show what happened in the river in that post. So... what should I have done on the river? Thx guys.
