Starting out in Pot Limit Omaha
When starting out in PLO I have two basic recommendations.
First, do a lot of limping until you learn what
hands you should be winning with. The NLH cheat sheets don't work the same in PLO. There may be some for PLO, but I don't know. Anyway, in PLO the hands you can win with are much different than in NLH. I even heard someone say "in PLO the starting cards don't matter so do your betting after the flop."
Second, PLO can be very profitable IF you are playing against newbies. If the people you are playing against don't really know what they're doing and you do then you can massively take advantage of that, even more-so than in NLH. This is because, unlike the first point, if you know what you are doing then you have learned when to be betting pre-flop and can easily get pre-flop calls when they are at a disadvantage. However, if people at the table are good, then it can be very hard to make a profit playing PLO because you will find out quickly that those players fold when you want them to call and raise when you want them to fold.
PLO can be even more fun than hold-em because of how wide of a range of hands that can be played well. But it can also be more expensive given that the only people playing it tend to be really good at it.
Anyway, try out these articles to see if they do you any good.
