thoughts about all street pl. i have seen villain 3-betting a lot especially me^^.
is preflop to loose?

on the turn i put villain either on overcards or an overpair because he dindt bet again at the turn.i decided to check to induce a riverbluff from him , and if checked to me to make a valuebet he will pay me off with an overpair
