How do you respond here? Villain was brand new, 2nd hand at the table. My first PLO8 session in many months.

Full Tilt Pot-Limit Omaha Hi/Lo, $0.10 BB (5 handed) - Full-Tilt Converter Tool from FlopTurnRiver.com

BB ($9.60)
Hero (UTG) ($9.75)
MP ($11.65)
Button ($11.10)
SB ($5.65)

Preflop: Hero is UTG with 8, A, 5, A
Hero raises to $0.35, 1 fold, Button calls $0.35, 1 fold, BB calls $0.25

Flop: ($1.10) Q, K, 8 (3 players)
BB bets $0.55, Hero ???

I don't think you need to continue this hand. There's still a player to act behind you, you have a one pair hand w/ no shot at improving, even the a is kinda an ugly turn for you. Just watch the BB for a round or two to see what that means for future reference.

Eesh.. Annoying spot, for sure.

The only real info we have is villain led right out with 2 to act behind him, in a pot in which he wasn't even the original raiser preflop.

Unless Villain is me, leading out multiway into a pot like that when only 1 low card pops up is generally sign of a legit high hand that is ready to charge A2xx to start their runner-runner magic.

Of course, if villain routinely fires at high flops (/wave), then I'd call him down a bit lighter. Regardless, this isn't a great flop for AA and you don't have much invested. Which of course raises the question: Is there a good flop for AA? a couple three hearts or an A on the flop is always nice... AAxx is a b!tch to play in o8b.

For the record: nearly anything he semi-bluffs with isn't really trailing AAxx too much in percentage points.

if he is any good he should be leading at that flop more often than he doesn't.

but as a default play at this level i would say just fold.
