Trap hands are hands that seem very good but can easily make you a second-best hand. These are the types of hands that can cause you to lose your whole stack. There are three types of trap hands in Pot-Limit Omaha:

1. The Small Pair Hands
2. The Low Wrap Hands
3. The Small Flush Hands

1. A hand with pairs below Nines is dangerous to play. When you flop a set it is very hard to escape the hand and, if you are up against a bigger set, you are drawing to one out. When you hold a hand like #6s-#6h-#5s-#4h and the flop comes #Qc-#Jc-#6d, you may find yourself in big trouble. The moment to play small pairs is when you do not have a lot of money in front of you, At this stage it is not so bad to commit your whole stack if you flop a small set. Or, for example, when you have something like A-A-2-2 or K-K-3-3, then you should play in the hopes of flopping the big set. However, you must always think twice before you commit a lot of money with bottom set on the flop.
   
2. The types of hands that are very deceptive and dangerous to play are the lower four connected hands, like #5s-#4c-#3s-#2c. These hands are dangerous because it is too simple to flop or draw to the low-end of a straight. When the flop comes 8-7-6 with this type of hand, you can easily find yourself up against a bigger straight, drawing dead.
   
3. Hands that can only make small flushes are risky hands. For example, let us again look at the #5s-#4c-#3s-#2c on a flop of #Ks-#Js-#8s. This will give you a small flush. You cannot commit a lot of money with this hand and, if you were to get any action at all, you would most likely be beat.
