97o against CO-raise

[wuarhg]

4 handed 20/40

I have 9[img]/images/graemlins/diamond.gif[/img]7[img]/images/graemlins/heart.gif[/img] in the BB, CO open-raises which he has been doing for the last 10 minutes. I don't know if he is tilting or what but he is raising alot of crap. He is 27/18 Aggression 4/3/2 after 2500 hands, but not playing like the stats say. He is overaggressive on the flop, checkraising and 3-betting ace high etc.

He raises, 2 fold, I call.

I check intending to fold if he bets.

I hate this hand.
