I have 400 behind playing PLO 1/3, I had won a pot with AAds AI preflop. I'm in the BB with KdJdKcTh, I call the straddle for 10, 3 other players call. UTG shortstack calls 10 with about 115 who seems inexperienced and shoves a wide range pre, UTG+1 who is tight and solid and a good hand reader calls (about 900) and a deep stack player with about 500 behind who plays a wide range and isn't good but knows something about poker and has a strong CR range of 2pair on Ax boards on the flop and plays at casinos raises to 25. The splashy CO with 800 calls, he's not very good and will make large 3bets with a wide range, the button a young not that experienced player calls with about 140 behind calls, I repot to 125, UTG calls all in for about 125, UTG+1 folds.
Now the HJ repots it to about 390 and the short stacked button calls AI. He's never done this before and I think my hand is just a gamble. Previously I had been able to get it my stack in 3 ways preflop but had 3bet repotted AI with a different hand and lost and didn't show. I think I wasn't expecting a 4 way AI preflop. HJ ends up showing the hand.
I think it's possible someone could have called AI with 5689ss in their range

is this a correct fold with the side pot calculation, I had about 280 left? It's just terrible to put in 125 and have to fold, I waited too long to repot
