Anything goes. After that, you can get 19:1 in the little blind if everyone calls - or in the big blind if everyone calls an under the gun raise. This allows you to go in with almost any cards except the very worst. You don't want to get into it with cards whose best flop is two small pair as the odds are probably not worth it. This rules out hands like 72o 82o 83o. One could make an argument for implied odds. But the chances your two pair will be dominated are just too good. You also probably want to stay away from 3-guts like 62o, 84o, and 73o. omaha chances that a flop will be ------------------------------------ three flush (me:0) 1.65 three flush (me:1) 1.27 three flush (me:2) .95 three flush (me:3) .69 three flush (me:4) .49 two flush (me:0) 13.98 14 two flush (me:1) 12.21 12 two flush (me:2) 10.49 10 two flush (me:3) 8.85 9 two flush (me:4) 7.28 7 rainbow (1 suit) rainbow (2 suits) rainbow (3 suits) rainbow (4 suits) 39.96 From a pair: ------------------------------ two flush (me:4) 7.28 7 flopping set 11.75 12 7.5 total flops 22100 ------------------------------ three of a kind 52
