Full Tilt Poker - No Limit Hold'em Cash Game - $2/$4 Blinds - 6 Players - (LegoPoker HH Converter)


Villain is a 40/10 and had been kind of floaty and playing pretty hands oddly.

What do I think that the worst possible move here is for me?
C/R or C/F. Maybe you think C/C is the worst, I'm still not sure yet.
