Although CO was very loose and passive, he would have had to have been extremely loose to call on the flop and turn without a [img]/images/graemlins/diamond.gif[/img]!

I suppose its possible that he could have had Qx with a weak kicker, or Jx or a busted backdoor straight.

Unfortunately you didnt have position on CO with the benefit of seeing him act on the river before you.

So overall I dont think that you would have been good often enough to make this call.
