Every poker room I go into you will hear players say I hate Pocket Aces,I always lose with them.Thats because they think they have Aces they should win the hand ,poket aces if not improved will only hold up 30% of the time.If you have pocket fours and a four doesn't come on the flop you dump your hand 90% of the time. 

So pocket Aces 70% of the time you need to improve your hand to win ,so play your pocket Aces like any other hand that you need to improve your hand bye the river to win.
