Odd, because I do this specifically to extract a river bet/call from more aggressive players. I'll have AJ or something similar and the flop will come A92 rainbow. Since he's aggressive, he's leading or check/raising if he caught anything. If he check/calls, I know he's peeling and will fold the turn.

So, I'll often check behind on a blank turn. At this point the aggressive player will frequently lead with total air or call with K-high or some smaller made pair.

It gives them a free card, but I typically only do it if my read says they have absolutely nothing. If he lead or raised me on the flop, I'm leading or raising the turn because he's going to showdown anyway.
