re: Poker & Omaha/Hi Lo..Popular place to play?
Ipoker (Titan, Noble, CD)
They have some easy to beat games running pretty often. The stakes people play are usually from .05/.10 to .25/.50
Cryptologic (Interpoker, caribbean sun, betfair, etc.)
They also have a lot of games running very often. The stakes people play are from .15/.25 to .50/1 and sometimes 1/2. The games are a little tougher, but they have exelent reload bonusses and you can get rakeback that are not deducted from you bonus.
If you don't mind playing shorthanded, this would be a good place to play. They always have a lot of games running and the competition is soft. But because they use 9-player tables you will often find yourself in a shorthanded game. No rakeback deals, and the rake is just as big.
Prima (Crazypoker, 32red, battlefield etc. )
They have games from .5/.10 to 2/4 running most of the time, and you can get some decent rakeback deals aswell, if you choose the right room to play from. The competition isn't very good either.
Have a lot of games, and not much competition on the tables, but it is impossible to get a rakeback deal, and the rake is just as big.
Loads of games running all the time, and probably a very good place to play PLO8, but I have just heard so many bad things about the site, that I have never deposited there myself. So I don't know very much about it.
The reason why I keep mentioning rakeback deals is, that when you play PLO8 the rake is usually much higher than it would be in a different game with the same stakes. Not because the casino want to punish the players, but because the average pot is much larger. So getting some good deals, are definately worth the effort.
