I would probably check-call the flop, and then make standard bets on the turn and river. Given that there are no draws on the board, a bet on the turn when a blank card falls will probably get called by a confused player with top pair, as would a bet on the river. The hand is somewhat vulnerable, but it's an easy fold if an opponent is raising you big or if the board happens to pair in an unfavorable way.

I think this is the best way to mask your hand and get maximum value out of a player who has flopped something marginal like top pair.
