Wow, I just caught 2 quads and a straight flush in H/L Omaha in a period of 15 minutes. The sad thing is that the payoff was really small!
My first quads I caught on the flop when my pocket three’s converted, I lead out with .25 but all 5 players remaining folded in order 
Then I caught quad nines when three nines flopped to match the one I had in my hand. I checked and someone bet .50 then it folded all around to me, I just called. On the turn I checked, he checked, on the river I checked and so did he….massively depressing win with quads.
Two hands later I had four for the straight flush with a gut shot (6 of diamonds needed) and it came on the river, I went all-in for $9 and got a call, lucky I did not have to split as I made a decent low hand as well.
Playing a monster can sometimes be tough and it really hurts when you don’t make anything on a hand that takes you all night to hit.
