Hi everyone

So I am a 100NL player that really enjoys dabbling in PLO and the more I work on my NL game the more I become aware of how my sizings are off when I play PLO mostly due to habits and the paradigms I am used to.

What would be a good resource to get more acquainted with the fundamentals of PLO postflop sizings ?

I also have RIO elite membership if anyone has recommendations from RIO etc

Thanks

Could you be more specific about your sizing concerns? (If the question is WRT preflop, in cash games I don't know that anybody trustworthy advocates for anything but pot-sized raises.)

WRT RIO: I'm not sure that many folks are going to be more helpful with recommendations than browsing their Learning Paths and PLO videos in general will be.

I will say, I sometimes find Galfond's sizing decisions in particular to be sort of weird, especially on the river (though I haven't been watching a ton of his stuff lately). I'm not saying they're bad, but I feel like he often uses weird, arbitrary sizings instead of just having, like, a "QP/HP/PSB" game tree, if you know what I mean. Those overcomplicated bets of his might confuse you a bit if you're still getting comfortable with the game. (And, honestly, I'd guess that he uses weird sizings in part to throw a wrench into his opponents' "defensive game trees".)

It's mostly about figuring out which bet sizes postflop are built around which hand classes/textures for me right now , the videos in the RIO learning paths are quite old (I think some are 2013ish) so I am not sure how relevant it is.

I love watching PG videos, Im trying to figure out what is decent for specifically this topic tho

You can endlessly complicate it but a good start is:

1/3 cbets on paired, mono, and straight boards. You'd often barrel bigger on turns, but that's most complicated. On mono boards you'd usually 1/3 flop and pot turns if you do barrel. straight and paired a lot more complicated, but can always simplify it to 75% turns. Would get you through most of it.

Cbet 75% (or 66% or whatever "mid size" is for you) for boards where you have 1 sizing. 50% and 100% or 33% and 100% for boards where you split. You don't go 33% very much in SRP except paired straight and mono, though. You can pretty much just never do it. Very low/awkward SPR you can start messing with it, but I don't think it should be priority.

Mostly go for pot size on drawy boards double barrelling.

Unpaired boards are NOT dry the way it is in NLHE. For instance, if you're a 3bettor, you pot with AAJ3 on J52, not small as you might in NLHE. That's because vs your range, Jxxx is often a flip, so it's actually a "wet" board in a sense.

On the other hand a board like A22 is super dry. You can bet 100% at like 15% psb or something if you 3b, and this is even if your opponent flat some aces pre.

There's a lot of leading in PLO, but I believe that's more understood in NLHE anyway so not "different" per se. Similar PLO uses a lot of river blocks. Betting tiny on the river IP is a lot less common. I mostly only use it as an exploit, and I think it's fine to mostly go for 50/100, mostly leaning on pot when you start betting multiple streets until river.

Also not too surprising, you tend towards bigger sizings OOP, but checking a ton. Multiway this complicates somewhat.

3BP and low SPR spots there's a lot of potting going around. It's normal.

Generally looking at solvers, the EV difference of the exact bet sizes is minimal as long as you put them in the correct bucket of small-mid-large sizing. I personally use 30%-50%-70%-100% buttons, and it works perfectly fine. I basically click 70% if I'm not sure, and split 50/100 if I wanna split, then do some 30% with blocks and/or traps, and some cheap bluffs, that kinda thing. Pretty intuitive.

Thanks Inky!

No problem
