I over play this or was it a bad beat? I was stealing and we got it HU with a decent flop for me (I think)

Two pair is only a good hand in Omaha you have other draws to go with it. When your opponent caps it, you have to figure you're in trouble. Stop betting into him on the turn and river unless you make your boat.

I would call his raise on the flop and check call the turn and possibly fold the river. if you had top 2 its a different story but the spade kills you if he was drawing and if he didn't have KT than the ace made his straight to.

there is really no hand here you can beat except a stone cold bluff and that will still get him 1/2 the pot for low.

there is really no hand he could have raised the flop with that doesn't beat you.

You would fold this PF? and not try for the steal? Thats seems pretty weak to me....
