PP 30, Random Turn Checkraises

[DpR]

I do not really get this play, but a lot of reasonable opponenets make this play against me all the time. To me it just seems like spewing on their part.

I have AJs UTG+1 and raise. All fold to the BB (20/10/1.4)who calls. Flop is Q,10,4, check, bet, he calls. Turn is Q, check, bet, he check raises, I call. River is a brinck he bets and I call. He shows A9o and MHIG.

To me it seemed very likely he had no hand on the turn. I can't really think of any hand I play as the villian did here so I am wondering if any posters here like to make the type of cr's villian did here (and do you think they are successful for you).
