Is this worthwhile, or should I just check-fold?

Opponent is 27/2.5/1.7 on 200 hands. His showdown stats are 31% went and 65% won. Against someone who raises so few hands preflop, should I just give up and check-fold the flop? Once the SB had left, I thought it might be worth investing a couple bets to try to work him off the scary paired board if he has JJ or something (he could also have AJ in which case I don't want to fold). I wasn't planning to bet the turn, but this queen just killed his hand if he was in calldown mode with JJ/TT, so it seemed worthwhile to fire once more. Did I lose too much here, or was this a good effort?
