The scoop is the thing, but it seldom happens.
Two ways to scoop
1, You have great Hi cards and there is no low hand at all, or
2 you got a great low hand, like 4 cards under 8 and hit the str8 with nut low, or nut flush it.
Are you talking Limit or NL Omaha. NL Omaha scares the bejesus out of me. I like FL, or even PL Omaha H/L, but will avoid NO Omaha like it is the plague.
KKQQ 2 suited should be limped, and depending on your read of the players, and game type, could be raised. It packs a lot of potential. Be completely ready to muck them in a H/L game when you miss totally on the flop
Personally I have taken a liking to double suited connectors centered on the ten when playing hi only Omaha.
