What turn card could come that would make a player want to put in a bunch of chips with the second best hand? I don't think there is one, so there is absolutely no reason to slowplay, which is are essentially doing if it gets checked around. If he won't give you action now, he won't later either unless you are beaten.
Edit: As for the checkraise option, I think a lot of players will fold top pair weak kicker to a c/r all in, but will call you all the way down if you bet out and keep value betting.
