Common river decision...

[legend42]

No stats on villain, but has been a pretty decent blind defender. I have seen him check-raise the flop a couple times. Not sure if I've seen him show down a hand after donk betting the river after a check behind though. Assume decent unknown, I'm interested in the standard play here:

6 handed, hero raises with AQ from MP. Only big blind calls. Flop is K 8 5 (2 suits). Check-bet-call. Turn is an offsuit 9. Check-check. River is offsuit Q. BB bets. Do you raise here in general, or just call?

raise. He's not going to play a king this way especially with a two-suit flop.
