100 PLO 6 max Bovada

Only been playing about 10 hands and already doubled up when flopped Broadway against original raisers flopped top two.

UTG - $99
CO - $120.50
BTN - $34.50
SB - $175
BB - $ 201 -- Hero

Hero - Ah 6h 6s 4d

UTG raises pot to $3.50, everyone calls around Hero in BB who calls $2.50 into $15

Pot $15.65

Flop

8h 6c 2c

SB checks
Hero BB - Checks....... Should I have lead at this?
UTG - bets $9.75 ---- $85.75 behind
CO - raises to $33.93 ----- $83.06 behind
BTN folds
SB folds

I have middle set and backdoor flush draw..... is this a call? Repot putting the other 2 all in? or just a standard fold?

Thx for any help
