[LunatiC89]

I played many sessions with villain.
So i know he is very aggresive...and he knows
that i know this [img]/images/graemlins/grin.gif[/img]
I make the Checkraise for showing strength.
What should i do at Turn and River [img]/images/graemlins/confused.gif[/img]
In the hindsight(can i say it so...sry for my bad english) i'm frustrated about my play. But i was scared that villain slowplay an overpair, because i often see him doing that before, by reason his aggressive image. So what's a better line for this kind of situations?!
