1. Your read on CO is pretty far off. You checked the turn to him and he didn't bet, and he just looks totally passive the whole hand.
2. You could have had the best hand on the flop and not have the best hand on the turn. What do you think the button is betting here when you check to him? Anything? And is CO calling any two cards?
3. What are they calling with on the river that you beat? A 2, 3, or a 4? Supposedly your opponents bluff a lot and you don't have a hand that's likely to be called by worse hands, so why don't you check and let one of them take a stab at it (or bet their better hand).

I'd be pretty surprised if you won this hand.
