Hi everyone. Brand new to RIO and my first post so bare with me. This hand occurred over the weekend I decided to play Parx for the first time because I heard their PLO action is fantastic. I waited 5 hours for a seat and finally sat in the 2/2 must move 4 handed then to the main game 100-500. They allow an utg straddle and if all in and heads up you can run it 1, 2, or 3 times. I am in the game for 275 and have built to 1400 in about an hour.

9 handed game. Effective stacks 550. Only reads are button is very lag woman who says she only runs once.
I am in bb for 2 and theres a 4 straddle.
utg opens pot 20, everyone calls except small blind, i looked down at 8h 8c 6h 3d and i call bc such great price.
flop 8d 5h 2c ($160)
i bet 50, utg call, and button call.
turn 3h ($310)
i check, utg check, button woman quickly bets 1 stack of red 100
i think for a minute and POT because we turned more outs. she has 400 behind. utg folds
she thinks and starts talking saying if i call do you want to run 3x? i didnt answer. then she says i have the bottom end of the straight and i turned a Q high flush draw but i think you have the nuts. she then asks again what do you want me to do? i sat there silently, then she folded.

Was my line bad?
