I do believe that sets are the most difficult hand to pick up. Especially if it happens in the later stages of the hand (turn, river) I have fallen victim to sneaky sets. But after reading these posts, i agree. not all the time but a lot of the time if you are check raised on the flop it means they've flopped a big hand top 2 pair or a set. Or they're just plain bluffing. Use you're judgment to decide.
