I think so. A couple of times this happened to me. I raised KK or something got like 4 callers, flop is something like JTx, check, I bet, call, call, call. Turn is a T, say, and it goes check, I bet, call, call, check-raise. Now he's check-raising into a protected pot (the callers are super loose donks). I think this is a potentially good move with a hand like AJ, you may have the best hand, and sometimes you get the PFR to fold an overpair. I dunno how often that actually happens though.
