I do it from time to time. Tonight I had AK in the BB (maybe SB, not sure), MP minraises, I immediately put him on ace-weak. Flat call, flop an ace. Check to opponent, he bets the pot, I minraise him, he pushes, I call, he flips AJ, MHIG and I win a big pot. May never have happened if I came out betting. This is also an ok way to play a set or a little 2-pair if you're pretty sure your opponent flopped top pair. As always, disclaimer of "it depends."
