BB is a pretty good solid player, CO is a bit of a loose goose preflop. he knows me as well and respects my play (i hope [img]/images/graemlins/wink.gif[/img] )

is there anywhere i can drop this? I know he only caps premiumhands (he'd coldcall AQs preflop). So with that in mind and after the flopaction he can be safely put on aces imo. Any set he would call my raise with on the flop in order to craise me on the turn. But theres just nowhere i could find a spot to drop this hand? o and he flipped over aces by the way [img]/images/graemlins/smirk.gif[/img]
