Given your decisions up until this point, I frequently just call the flop bet. It's extremely unlikely that your opponent is drawing, and a checkraise has the potential to scare away hands which may be willing to invest heavily in the pot if you take a softer line. Something like check/call flop, lead turn, lead river can still get all your chips in the pot and the turn bet is generally not interpreted as great strength. You could also check the turn and lead the river -- he most likely has a good enough hand to bet again for you. But against passive players you may not want to take that chance.
