Blind defense checkup

[private joker]

Commerce 20. Villain in this hand is an aggressive blind-stealer and probably a pro. Doesn't play brilliantly but is probably a winner. Skinny, middle-aged Armenian who always seems to be looking for a table change to get the best of it. He yelled at a drunk Arab after a hand and they got into it, and he called the floorman over, reported the Arab's use of an obscenity, and got the guy kicked off the table.

Anyway.... Folded to him on the button and he predictably raises. SB folds, and I call in the BB with 8[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/heart.gif[/img].

Flop is KQ6. I checkraise, he calls.
Turn is 4. I bet, he calls.
River is 4. I check intending to call.

Standard?
