Man. I don't understand PLO8. It hates me.

play was on cake, on a different computer, and I exited before I saved the hand. So bets are estimates. This is half a fml and half a "I have to call, right?" post soo anyway, here we go.

we were playing 6 handed PLO8 .25/.5

hero BB (~$38)
loser utg+1 (~$27)
winner mp1 (~44)

hero dealt

loser calls $.5, winner raises to $1 hero calls $.5 ... everyone but 1 calls.
flop (~$5):
hero bets $5 loser calls $5 winner calls $5

turn (~$20):
hero bets $20 loser folds winner calls $20

river (~$60):
hero checks, winner bets $15

... I sit there for until time is about to expire, say fuck as dry as I could, and call.

winner sweeps with:
hero loses not only his stack but his dignity with:

I gotta call there tho, right? I mean, more times then not its just a low that caught up, and not a sweep... or should I have saved myself the $12?
