hey guys, first post in the plo thread, played this hand yesterday at a private game in dallas tx. is a 2-5 plo and plo8 game
I really dislike the way I played this hand in a lot of ways so im looking for some constructive criticism please.

Hero $450 effective stack
PLO

PRE
Villan limps 5 Utg +2
Hero Utg+3 makes it 30 AA 7 10
Button calls
SB calls
Villan calls

Flop
694
Sb check
Villan check
Hero Check.. I decide to check because I don't want to get raised with my stack being a bit awkward if I do. ( most likely a mistake specially having the gutshot )
Bttn Check

Turn
3
SB checks
Villan $75
Hero calls
bttn and sb fold
decided to call even tho 52 amd 57 gets there I can rep the nut flush on a river club and my hand is very under rep plus still have a gutter for equity and I block one of the sevens .

River
6
Villan $145
Hero????????


what to do here?
I think is an odd bet of his part, obviously we are bluff catching at this point. even tho we beat most 2 pairs now if he had 52 would he bet in this spot? I mean what does he expect me to call with? so now he has to have a boat correct? I completely butchered my hand and don't know if not betting flop was the mistake I made or flatting turn... anyway thanks for the feedback im a post a spoiler

Just noticed that I posted this on the small stakes instead the high stakes thread sorry....
