[BluffTHIS!]

With that many players and lacking the K of the suit I would check as well. By betting and being called you gain no idea whether you are being slowplayed, drawn against or set up for a steal play on the river. You want to play a small pot here if you do play. Assuming that you were going to fold to a reraise behind on the turn and check/fold in a 3 way situation on the river unless you made a set regardless, then the turn call is fine. As far as calling the river bet, unless you have notes that he is a frequent bluffer you are most likely pissing your money away.
