I have being trying recently to transition from a PLO luckbox recreational player to really studying and thinking properly about the game. I have been playing 2-2 PLO at Parx in Philly and have some newbie questions relating to optimizing strategy (I won't use "GTO" as I'm nowhere near that in my study). Please excuse if these questions have been addressed previously or are ultra newb/obvious.

1. No limping ranges.
I've listened to JNandez talk about never limping, mainly due to over coming the rake. But Parx is a timed game, so does this apply?

2. Folding low EV hands that might get opponents into trouble.
I've been taking some of the quizzes in the PLO Mastermind course and some of the hands being advised to fold in EP would never be folds for me. Examples:
78JQ
78QQ
78KK

At the low stakes at Parx (and similarly The Borgata) the majority of opponents are weak with obvious exploitable tendencies. I know this because I'm shite and I can outplay many of them. My strategy is centered around playing many pots against those weaker opponents and looking for situations where they can make big mistakes. I obviously stay clear of those that know what they're doing.

Here's an example:
I'm in the CO with a terrible holding:
3577
But the button is a highly charitable fellow who loves to say "Pot" with bravado and bad cards. I'm literally trying to play every pot he's in and especially HU. I'm only folding the worst of holdings. It's folded to me and I limp. He shouts "Pot" (even though it's only $10, he never misses an opportunity) and gets the blinds to fold. I call in a weird backwards isolation play. We're about $700 effective. The flop includes a 7 with 2 s and he hands over his stack after getting it in and missing his flush draw with no other equity.

But am I thinking about this wrong, especially based on the mastermind direction to stay away from those lower EV hands?

You can introduce a limping range, it will add some EV, but I think if you're a newer player, it's a good idea to keep your strategy simple and refine it first and explore other strategy branches once you're more comfortable with your theoretical approach and intuition. I personally add a limp range and I think it adds to me EV, but most players would do better to just never limp.

As a less experienced player it's really hard for you to accurately quantify your edge and how much EV you can overcome with your skill edge. I'd avoid doing it too much in case you vastly over estimate it. That said, I would play those hands myself and I think they are strong enough for you to play them.

Limping 3577ds is ATROCIOUS. It's especially worse when you know your opponent will pot. Especially in position. It's maybe defendable if you're IP but with a hand like that and you're not an extremely strong player you really shouldn't. Even though you can play looser vs weaker players, this is not a hand that gains EV vs a looser range. It does not play big pots well or a high betting or continue frequency well.

You should focus in getting into profitable spots not just see players as piggy banks and try at it whatever chance you have. Again, newer players do not have a good frame of reference for EV.

Thank you for the awesome response. I really appreciate the advice and coaching and will totally apply what you've shared.

I use preflopper to analyze my game. it shows ready-made GTO solutions. My game has changed a lot since I started using it. I used to grossly overestimate the small rundowns. Also i didn't 3bet what needs to be 3betted.
