commerce 40, weird action vs 2p2er

[Surf]

Decent commerce 40/80 game, running 8h.

UTG+1, a passive but not terrible player raises. Earlier he open limped UTG and I Isolation-raised from the button and an observer commented "that guy limped utg! That's like a 3bet! and you still raised!" That's certainly an exaggeration, but he has not been getting out of line with his pfrs.

A 2p2er who I know well and who knows me well CCs on the CO. He's been playing pretty solid for the last 3 hours, is stuck a bit but isn't tilting. He's gotten out of line a couple times (3bet some cheese vs a lag, got caught 3barreling once) but that's it. I call 9[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/spade.gif[/img] in the BB.

Flop: 9[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/club.gif[/img]

I check, utg+1 bets, CO calls. I c/r, utg+1 3bets, CO now calls 2 cold, and I call planning on c/r'ing the turn.

I check, utg+1 bets, CO now c/r's. Hero ...?

What do we think of how the hand has gone down so far? What's our plan?
