Good Ole Ace Two – Omaha Hi Lo
One of the biggest downfalls of many new Omaha Hi/Lo players is not willing to fold Ace / Two. Players tend to think it is invincible and as long as you have it, you are guaranteed to win low. Several time you will see 3 people all in on a PL Omaha games and two people split the low with A 2 as their pocket cards and one person will win high.
First thing to remember is the several people can have Ace/Two in a hand and they are guaranteed to call it if they are dealt it. You always have to be cautious with a low flop if several people are in the flop. You can tell if several people are calling and trying to hit one more low card to have the nut low. Also realize that not every hand will have a qualifying low.

Chasing can become an epidemic while holding Ace/Two and flopping two low cards. Do not bet if you did not hit any high and are just chasing the low. Do not get sucked into to chasing if the other player bets big on the flop or turn and all you are doing is chasing one more low card. This will sometimes result in you getting quartered or losing the whole pot.
So do not fall in love with your Ace/Two like they are Aces in Holdem, don't' be afraid to fold them!
