The reason check raising is bad is because people call too much, so you won't fold out better aces or high clubs. Plus you still have the original bettor to contend who either has you badly beaten or has a strong draw. With his position he can either extract more bets from you with his strong hands when you play aggressively, or draw cheaply with a high club when you play passively (check the turn).

As I think about it, raising might be better than calling, or at least close to it. Still, folding is best because your odds of being good at the end of the hand are less than the effective odds you are being offered to see a showdown.
