I used to do this: after raising preflop, and getting the hand heads-up against another player who had position on me, whenever I opted to check, it was almost always with the intention of folding to a bet. I think it's useful to occasionally check hands that you have the intention of calling with in these situations. Usually I'll do this when I flop something marginal and I don't suspect a worse hand will call a bet, but a worse hand may bet.
