line check...

No reads, hes been here for <2 orbits and hasn't been out of line. Flop I call, any merit to a raise? He has a hugely wide range in my eyes and Id rather fish. Q on the turn and he checks . I think that he either wants me to bet and he will c/r or he has like AJ/KJ/A10 and the Q scared him, or some dumb air. If he has one of those hands he has very few outs and likely will only call down 1 street so Id rather bet the river when I have more knowledge than the turn when he could be raising. When he checks the river I know Im good, $8 too small?
