I will not play almost any Ace out of position...At a full table if you have an Ace there is around a 60% chance someone else has one also. Say it's not an all-in bet just a two bet or so, Say you have AK he calls with A/3 an Ace and three comes on flop..you now have top pair, top kicker,,wam oh you bet big or go all=in and he shoves,,,see you later
