Depending on all four cards, just open fold. Unless you have good JJ fold to the raise. Don't donk bet flop.
By turn if villain is truly right passive he isn't calling pre. or flop with many 5's, so he's probably got QQ ... but then that's also likely given you posted.
Given no reads at live 1/2/5 I'm not folding the 3rd nuts for 1 SPR on turn, but probably shouldn't be in that spot.
I’m a hold Em player getting comfortable with Omaha but why would anyone fold that turn? I’ve never counted the possible number of combinations to determine if someone can be holding QQ in a hand like this but is it a frequent enough number to fold here?
I’d definitely half pot the turn to get value if I do have the best hand and not chase someone out with a 5 hanger.
