This one is a little weird. Converter doesn't work for this site.
CO has capped preflop with K2 before. Button is an unkown, although he has shown down some cheese.
Preflop, I have AdKh in the SB. Folded to cutoff, who raises. Button calls, I 3 bet, CO caps, Button calls.
Flop comes Qs Jd 3c. I check, Co checks, Button checks.
Turn 9d.
Check, check, check.
River 9s. I check, CO checks, Button bets, I call.
I don't know, I'm a little lost in this hand
