It caught my attention in some PLO videos from Phil Galfond that he usually says "legitimate hand" or "legitimate range", when referring to a hand/range that would be "expected" for players to have in specific spots. Of course, those are just general guidelines and you have to adjust to player types, game dynamics and the imponderable.

But, as a player coming from NLHE, I still struggle with those ranges when trying to hand-read in PLO. What are "legitimate" ranges to open from each position, to flat IP or OOP, to 3bet, to call a 3bet, to 4bet and etc. I think that  a theory video on hand-reading in PLO would be great for us beginners in PLO.

Thanks in advance,
