turn c/r, standard? spew?

[Sporky]

i haven't played many hands against this opponent, just a few orbits. he seems a little loose pf, standard aggression, but i've noticed he has bet most of the time he is checked to.

is this c/r a spew?

I would bet out turn again but if you knew that every time he bets when checked to I like the c/r. Plenty of draws to charge and he might call down with some kind of 5-x 7-x hand....maybe even king high?
