10/20 Rivered underfull on a paired board
 

I realize that this hand isn't really 'important' in the long run, in that the pot was small, the villain had a small stack and the situation isn't common, so that it's hard to consistently leak money in these spots.

doesnt seems like they have much, I'd minraise to try too look like I'm trying to buy it(and get paid by a small pair), it will look suspicious, maybe he makes a stupid resteal

I don't think Villain will pay off a raise with a Q or J. Calling is probably better.

Why not bet the flop though?
