Don't fall into the trap of overplaying AAxx or KKxx.
My favorite hands are double suited connected hands like:
789T
5678
These hands either draw to the nuts or they can be easily folded.
Hands like:
AKQT
AAKJ
These hands are obviously nice, but you will be in real danger against me on a A47 board. That's because it's hard to lay down top pair (especially by inexperienced Omaha players who use Hold'em logic in Omaha hands).
