This will be a quicky, but I need some answers. Couple of days ago, I was looking around on Full Tilt to rail some high-stakes games. With no durrrr/Ziigmund/Hansen/Ivey/Antonius around, it wasn't that much fun, but I cought attention on the mixed PLH/PLO games. I sat down at a 0.02/0.05 table, which is way below my BR, so I felt comfortable. We started out 5 handed, but players eliminated and left, and I found myself playing heads-up. On the first hand of HU, the first strange hand:

Me: AK9x with the K9 suited

I raise pot, but the opponent quickly re-pots it. I call, although an all-in wouldn't be that stupid here, but I just dont feel comfortable 4-betting in omaha, as basically every comfrontation is a coinflip.

Flop: KT9 rainbow. He bets pot, and I move all-in. He calls, showing KTxx, for a hand that (in my opinion) is clearly not a 3-bet preflop hand. OBV no help, and I'm forced to reload.

We play the 10 hands of PLO, the 10 hands of PLH, and he 3-bets about 80% of my raises. He's clearly an agressor. On the next PLO part, I find JJA5 on button. He OBV 3-bets me and I 4-bet, and we're allin. He shows QQxx. Flop is 238, and it turns out 9 outs are just not enough for me. With this I drop 2 buyins, I left the game.

So my question would be:

Did I overplay these hands proving to be a fish in omaha OR
Are these just coolers OR
Is omaha just simply the game with the most luck factor?

TY all!
