ive switched to omaha hi 6m cash games im only playing 10 and 15 dollar games max but i find it the most exiting wild volatile game going!!! i love it! but remember that however good your hand is preflop ,yopur opponent is not that far behind you at worst 3-2 so im told. my advice is forget what you have learned in hold em or you,ll get smashed ,my favorite opponents are players like this ,there raises are predictable e.g aaXX kkXX and i often play a raiser with my connecting hole cards ,
i wouldnt say im a great player but i have been consistent ,i have no software for omaha and can only say to learn you have to get involved and get some sessions under your belt,there isnt a wealth of omaha literature out there and once you have gone thru what is out there (super system 2 etc) you wont know much more than the average holdem player so flying time will make a lot of difference ,also only draw to the nuts!! ,
PLO is such a big wild game that there is an awful lot to learn ,but i enjoy wilder games and am fed up of playing holdem cash games (play standard has increased ,so its harder for me to find a decent edge ) good luck mate (that also helps)
