[Bluffoon]

CO 12/6/3 ASB 18% over 250 hands.

Me BB K [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/diamond.gif[/img]

CO Open raises. I call. Flop is:

4 [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/club.gif[/img] 4sb

I check raise. He calls.

Turn 2 [img]/images/graemlins/spade.gif[/img] 4bb

I lead. He raises I ?????

Also preflop should I be folding this to an 18% ASB? Even after only 250 hands?
