Live Home Game: Hero has ~$1700 with blinds of $1/$2.
6 handed: Hero raises to $20 UTG with 8 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/heart.gif[/img]
Villian~$1800, calls on the button. He is capable of playing any two cards so I tend to play my hand out instead of trying to read him.

Flop: A [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/heart.gif[/img]

Hero bets $50, Villian calls $50. Pot ~$140.

Turn: 6 [img]/images/graemlins/diamond.gif[/img] Hero checks. Villian bets $100. Hero CRaises to $350 straight. Villian insta calls. Both of us still have over $1000 left in our stack with the pot ~$900.

I wouldn't checkraise this turn as you've basically just given your hand away.

On the river, I would bet $475. My guess is you bet a bit more than this, called a raise, and were shown 7d8d.
