K/Jo...Call River?

[ncboiler]

I really need help play K/Jo. Villain is 41/6/0.71. This is an easy river fold right? Even though I didn't play it that way.

2 over cards and decent backdoor flush warrents a call?

Top pair good kicker. BB is fairly aggessive and not a bad player but I think I have him beat. Then villian 3 bets me. The nerve of this guy!!! He has to have a min of j/10 I'm thinking.

River: (12.50 BB) 7[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">Button bets</font>, Hero calls.

Pot to big to fold.
Final Pot: 14.50 BB
