Villain is a good player, tagish stats, if i remember correctly like 18/8 or something. Preflop clearly says "aces" but I can pretty much call for set value, flop comes pretty but with no king and he bets fairly big, anyone lays down here? I just cant get rid of my kings so I call, on the turn he bets big again, I just cant see this being anything else than AA, good laydown?
