Please don't call my CR bluff! nl600

[mj12]

party 6 max
villain is clit_smacker seems like a decent tag. haven't noticed him getting out of line, and we haven't really clashed as of yet.

I am probably around 20/15/4 at table, reraising pretty regularly preflop and not seeing many showdowns.

villain has 640, I cover

preflop; hero is dealt A8c
I open in CO to 24, villain calls in button, blinds fold

flop (57) a [img]/images/graemlins/diamond.gif[/img]j [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]
hero bets 40, villain calls,

turn (137) k [img]/images/graemlins/heart.gif[/img]
hero checks, villain bets 124, hero CR all in

what do you think? also what do you think villains range for calling turn is? I think he folds j9 and has trouble calling with aj and calls with anything better.
