Shalara ???

Don't remember much about this table except that it was fairly loose &amp; passive, and the players seemed straightforward. I can figure CO to call with any piece or draw, though if he had an ace, I'd expect a flop raise (unless it was a very weak ace). I was hoping to take the pot down with a flop bet before anyone could draw to a better hand.
