No reads on villain, he is new to table. I never know what to do in these spots, i think the raise on the flop was fine but unsure of what to do on the turn when i missed. How much should I bet betting on this turnl? Any advice on how to play this hand, or bet draws effectively when i miss on the turn would be helpful. Thanks.
