No reads on villain. I don't have PT Omaha and this is definately not my main game.
Does anyone fold this if its not suited preflop? Or am I being to nitty?
Figured I might be good on the flop and pick it up uncontested. Is my turn bet good when villain shows no resistance?
River call is horrible right?
