I'm new to the game (now been playing about a month of .25/.50 PL Omaha) and I'm wondering what hands you raise with preflop. I've read numerous places, including this forum, that Omaha is an after-the-flop game since no reasonable hand has a huge advtantage over any other reasonable hand preflop. So my question is, what hands should I raise with preflop? I have a feeling that I am misplaying a lot of hands preflop, but I typically don't raise (except with complete monsters like AAXX double suited), however I do call preflop raises with strong starting hands (because in cash games it seems that someone agressive preflop will really pay you off when you hit your hand).
To give a concrete example, let's say you start with Ac Kh 10c Qs. This is a strong drawing hand, but without the right flop it is worthless. Do you raise preflop with this hand if you have position? Does your answer change if the hand is double suited?
