PLO25, Turn decision, 2 pair, nut fd.

c/r turn and fold river.
I don't see any other options.

Fold preflop maybe or is that too tight?

can't fold preflop to min 3bet.
But do u mean not to open this utg?

Not to open UTG.
Sure you have got a flush draw and a pair, but the pair is useless if you don't hit a set (it's so low that it won't survive by it self). You have'nt got any straight potential either so it's a fold instantly imo.

Preflop seems ok to me, but I'd play it more aggressively on flop and turn.

You have an extremely weak hand A966 isn't playable at all (being double suited doesn't change this because having nothing but a flush draw out of position is a surefire way to hemorrhage money.

This is why we fold preflop, exactly because of flops like this.
Everything that happened from the flop onwards was a direct result of your bad preflop hand selection and there is no good way at all of playing your hand postflop.

Hopefully you can avoid situations like this in future by not opening hands like this from UTG. It's okay from the button because you can take free cards to hit your flush, but this wont happen when other people have position on you.
