Hero cutoff about 1500(Solid and VERY tight image)
LAG UTG 2000

Lag Raises to 20
Hero Calls with JhJd7h2d(Can seem a bit loose but people really like to play their pairs in this game. If I overset somebody I can probably win quite a bit off money. Also the guy to my left is a little tilted since he has a bad night.)

Flop Jx8h5h BB,UTG X Hero bets 50 into 85

Reasoning for betting is simple if somebody has 88/55 hope they will X/R they could even jam a wrap like Th9hQx or some kind since they belive they have flush outs against me. I am repping exactly what I have but X back hoping BTN bets is kinda optimistic since even he will not randombluff in 4-way pot with such a drawy board.

BTN folds, BB and LAG calls
Turn Ah Pot 235
BB,LAG X Hero X(No reason to bet I would X all my 2pairs and sets here just want to see a free river, they will also NOT suspect I have flushed here. So Deception Value.)

River 3x BB X Lag bets 150 into 235 Hero?

I am 100% sure BB has no flush both cause he X and the way he acted after. So LAG did raise UTG but he can do with a VERY wide range, have seen him do it with 8833. He is OFC repping a Q/K high flush, BUT he can have a lower flush and since he WONT put me on one he will probably bet his for value hoping I call with a set/2pair. People on this game can call on such boards with wraps without flushdraws aswell. 3dly me and BB have showed weakness a good spot to bluff. At the same time his range is mostly towards higher cards and therefore higher flushes. So what to do?
