T8s in front of a rock

[molawn2mo]

Party 10/20 and I have been running over the table with cards to die for and always showing down g00t

MP is sl-p
HJ is rock - weakish-passive, sort of the type that may be playing above his roll
CO is a fish buddy
blinds are average badish

Mp1 limps, I overlimp w/T [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/spade.gif[/img], CO raises, all fold to Mp1 who calls as do I

8 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/spade.gif[/img]

MP1 checks, I bet, Rock raises, MP1 folds, I 3bet, Rock caps, I call

I ??? and why

edit to clarify: my notes on CO and blinds were made to "explain my overlimp." They folded preflop. The Rock is the raiser.
