PLO10 deep with an aggro behind w NFD and straight blockers

I wouldn't play this hand from UTG, and definitely wouldn't limp. Definitely not 200bb deep, as you don't have a lot nut potential. Or actually potential to hit anything strong enough to be happy 200bb deep oop (besides rare flops where you actually do hit the nuts). I know the hand is in top 10% in PPT rankings, but playing multiway pot oop with this hand is just going to get you into problems. Especially against a guy that is somewhat aggro postflop as you can't use flush draws as semibluffs that well.

Yes, I should have folded pre. But if somehow, I got ,to a situation like this? I mean, I open this hand from co (or limp ♦ ) and the same situation arises.

Why sit on a table with a: "very agressive and floats/semifloats a lot (even when I raise him he calls with very marginal hand and bluffs on riv), he is a bit spewy IMO" on your left?

Fold pre-flop for sure. Kyyberi told everything that's necessary for this hand.

As played,I'd just check flop and check/fold turn.

From utg and aggros/LAGs behind, I'm folding. Not limping anything, only exception could be from SB against aggro with some hands.

Flop, you've blockers, so I dont mind repping straight. Problem is, that you could get raised by other non-straight hands, vecause nuts could be weak hand on this board against big draws, like sets+FD, FD+bigger wrap. Also, some bad cards OTT to continue bluffing.

Turn, a bad card :-p You're repping straight, sets dont usually donk this board MW, 2prs definitely wont. Ofcouce you could, or you could've 8, but good card to try bluffing for villain, you cant continue with most of your hands against raise, so I probably would just check here. Considering maybe bluffing river if he check-backs, to get weakest of hands that beats us to fold.

It's bad to rep the 76xx here because it will remain the nuts on approximately 12% of rivers. + everything what everyone said before ♦

"Notes from this guy: he is very agressive and floats/semifloats a lot (even when I raise him he calls with very marginal hand and bluffs on riv)"

And still you decide to rep 76 on a board that has flush draw AND higher straight draw in it? If opponent wants to float, he can represent a hand that beats 76 on 2/3 (66%) of the turns.
