I have started playing in PL Omaha a bit but still having some troubles. Is there a few guidelines some people with more experience can give.
-Should I be playing more hands?
-Is it ok to limp more preflop?
-Is it smart to get all in preflop with aces?
-Should I expect more wild swings on my bankroll?
-An idea to make reading a st easier(sometimes miss this)?
Good advice already contained here, but I'll offer what I can as well:
-Should I be playing more hands?
-Is it ok to limp more preflop?
This really depends on the table. If you are at a table with people who don't really know appropriate PLO hand strengths and will overvalue their bottom two pair, low straights, and non-nut flushes, I will limp and get in on many hands because it is likely I will get paid off a lot post flop. At a table with more knowledgeable opponents, I prefer to be more aggressive and selective preflop.
-Is it smart to get all in preflop with aces?
Again, this depends on your reads on your opponent. Generally, in a multiway (3+) pot with even stacks and against decent opponents, naked aces are very fragile holdings. They are much better supported if at least single suited (double suited much better) and with high connectors or another high pair.
If heads up or if I think I can isolate against LAG opponents that have shown very poor opening hand selection, I am usually pretty happy to get it in preflop with semi-supported aces if given an opportunity. Usually in these cases, you are no worse than about 2:1 favorite and sometimes as high as 3:1 favorite.
-Should I expect more wild swings on my bankroll?
As compared to NLHE? Perhaps. I think people usually recommend something like 40-50 buyins to play at PLO comfortably, or about double the bankroll for being properly rolled for NLHE.
However, I do think it is possible to play a very tight style at the micros and actually encounter SMALLER swings than in NLHE micros. This is because in pot-limit games, you can control the pot size much more easily against bad opponents, whereas in NLHE your entire stack is possibly at risk from an aggro maniac on every round of betting.
-An idea to make reading a st easier(sometimes miss this)?
I'll assume "st" here means a straight? I think this just comes with hand experience. Also, counting outs when you have possible wraps is important to do, and this too comes with experience. I remember when I was just starting with PLO that I would sometimes miscalculate wrap outs, but after about 25,000 hands or so it starts to become second nature if you are making an effort at practicing it.
