Trap hands are hands that look good, but can easily cost you your whole stack, because when you make your hand it more than often proves to be second-best.

In Pot-Limit Omaha there are three kinds of trap hands:

Small-Pair hands
Hands with small-pairs will often flop bottom or middle set, which are very hard hands to get away from when you’re beat. Hands like 5543 can be easily dominated on a flop such as KQ5, and can suddenly be drawing to one out. So always think twice before comitting chips with bottom or middle set.

Low-Wrap hands
Another dangerous type of hand is the low four-connected hand, such as 5432. Although it looks like they have great potential, it’s very simple to flop or draw to a low end of a straight. Which most of time means you’re drawing dead.

Small-Flush hands
Small-flush hands are risky hands. When you flop a flush with a hand like 5432, you can’t commit a lot of chips, because when you get any action at all, you’re likely drawing dead. So avoid small flushes!
