Background: I just started with PLO some weeks ago and until now, I did work only on post-flop situation were I am heads up. I had in this hand in my mind that multiway pots should be played carefully with none nuts hands. The main question in this hand is, does the SPR rule count in multiway pots? If yes, then I would play on the flop already for stacks.

Hand converted by PokerTracker 4
BTN: 131.8 BB
SB: 65.2 BB
BB: 100 BB
UTG: 153.4 BB
Hero (MP): 130.4 BB
CO: 282 BB
SB posts SB 0.4 BB, BB posts BB 1 BB
Preflop: Standard Play for me AA triple suited with 2 Broadways
Pre Flop: (pot: 1.4 BB) Hero has K♣ A♣ 7♣ A♦
UTG raises to 3.4 BB, Hero raises to 11.6 BB, fold, fold, SB calls 11.2 BB, BB calls 10.6 BB, UTG calls 8.2 BB
Flop: here, the tricky part starts. I did not have any stats or reads on the villiams. Great Flop for me If it would be HU, its an instant C-Bet but we are 4 way and the SPR is below 2, so I would commit myself with a C-Bet. What beats me here is 55, 66, K5, K6 and I am blocking the K. We are 4 way so I was not sure how likely a 55 or 66 is.
Flop: (46.4 BB, 4 players) 5♦ 6♠ K♥
SB checks, BB checks, UTG checks, Hero checks
Turn: I got trips, but nothing changes what beats me on the flop still beats me but now a flush draw is possible. But there was no action on the flop. Now BB bets half pot. My thought is maybe BB was waiting on the flop to C/R me because this is a good flop to C-Bet for me.
I did analyze it with PokerJuice and I got the following numbers:
Range Distribution
Against a loose range PFR 30% excluding OOP 3Betting range of 4%
What beats me
55, 66, K6, K5 would be 4.99% of the time in his range
What I beat
KQ, KJ, KT would be 7.27% of the time in his range
With the OESD and Flush Draw
What beats me
55, 66, K6, K5 would be 5.02% of the time in his range
What I beat:
KJ, KQ, KT, 78, SS would be 47,87% of the time in his range my EV 74%
Against a tighter range PFR 15% excluding oop 3Betting range of 4%
What beats me
55, 66, K6, K5 would be 3.29% of the time in his range
What I beat
KQ, KJ, KT would be 8.91% of the time in his range
If I include the OESD and Flush Draw
Beats me:
55, 66, K6, K5 would be 3.29% of the time in his range my EV 12%
What I beat:
KJ, KQ, KT, 78, SS would be 47,87% of the time in his range my EV 74%
When I see these numbers, it would be an all-in against a tight or loose range but would it be an all-in with a passive player?. My thoughts in this hand is to call on the turn and evaluate the hand on the river.
Turn: (46.4 BB, 4 players) K♠
SB checks, BB bets 22 BB, fold, Hero calls 22 BB, fold
River: I do get pot odds of 2.36:1 (29.75%) so now it would be at least a call
River: (90.4 BB, 2 players) 3♥
BB bets 66.4 BB and is all-in, fold
BB wins 86.8 BB
Summary:
If I knew the SPR counts in multiway pots, I would play for stacks on the flop. With the analyzed range distribution and the SPR on the turn and the possible OESD and Flush Draw I would play here for stacks but what if villiam is passive?. With the pot odds on the river it is an easy call.
I am happy to get your feedback. Be nice ;-) it's my first hand in the PLO HH forum.
And good effort you put into the hand analysis. 
also note that SB is not fullstacked so the 4way scenario becomes even less important
