my real question is value betting river over valuing my hand? I thought if he had a better Q or a straight he would have tried to build a pot for himself by now and i thought he might station with J10, 910 maybbbeeee he could have a worse Q since he called a min raise from the blinds I guess suited Q8 is possible. 

all that to say i was probably way off since i value bet my Q and he just called with a straight. 

I do often over value my hands i think and i just want to know if this is one of those spots or if it was just a cooler....

Thoughts much appriciated
