I bet the flop 1/2 pot (or meant to...should've been $2+) since there was only a real draw for 9 10, and to minimize a loss to a set, but a weaker bet might mean people think I'm C-betting high cards so it can backfire, and a larger bet will be called both by top pair and sets so I think I see what you're saying. I was playing a little weak after overpair vs. set seemed to happen almost every time the last couple sessions. The turn was strange like you said, why wouldnt he c/r if he had a monster. Thanks for the comments.

He ended calling my min raise and checking the river with a pair of 5 (5 6 suited). Next time I'll get him for more!!!
