5/5 PLO: noob bluffing in 600BB pot

[Poker monkey]

I don't quite get what you're trying to represent on the turn. Surely with a set you'd have bet full pot; same with top two pair, having missed a check-raise on the flop. You're not repping KJ on the turn, so potting the river when the ultimate scare card comes looks bluffy. He's only got about 3/4 of the pot left on the river and gets pretty good odds to call if he has a made hand. And a hand like KJxx with spades seems very much within his range. It'd make sense for that hand to take a free card on the flop.

Also, does anyone else fold pre-flop? Position is key in PLO and this hand seems a little bit weak to be playing OOP.
