3/6 Hand for debate...

[xGoreDudex]

I am in the BB with K9 suited.
I check for the flop which comes down

3 [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/heart.gif[/img]

I bet, two callers.

Turn is K [img]/images/graemlins/spade.gif[/img]
I bet, 1 caller

River is 2 [img]/images/graemlins/diamond.gif[/img]
I bet, villian raises, I cap

Villian turns over J [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/spade.gif[/img]
for a Flush Jack High


Any idea of how I could have put him on a flush? and also was my agression approiate for this hand...just trying to improve my post flop play...
Anythoughts would be appreciated
