Thanks for the advice and insight guys. I really didn't have much of a read on this guy and kind of just assumed he was some donk, and for this reason didn't put too much thought into the sizing of my turn bet. Nuts, I like the idea of betting small on the turn but, but for me personally i think checking behind on the turn would make it easier for me to evaluate. This way i can reevaluate on the river and give him a chance to bet at it with hands that I beat (although I likely am beat by hands he bets here), or if he checks i might be able to get some value from hands that otherwise would not call on the turn.

Is this the correct logic for checking the turn?
