What hands will you go all in preflop(meaning raising a re-raise, etc)

Is is ok to go with a low hand against one player?

For instance if you have A, K, 2s, 3s ... is that an all in hand? I would suppose not, but curious.

Do you just want to play Aces ds, 2 high pair, etc? Or other high cards AKQJ ds? Do you stay away from low hand because the low only gets there 60% and you just split the pot many of those times?

Let me first say that I hate no limit Omaha 8. I think pot limit is a great game because of the progressive nature of the betting.

That being said, there are hands that I'll reraise with preflop and have no problem getting all in with preflop.

Probably any AA2x, AA3x, AA45, of course single and double suited makes them all the better. Maybe A234 double suited. That's probably about it.

I was talking about pot limit omaha.

No. You should have some outs for high.

My personal fav. all-in hand is QJ109 double suited.
