I’ve been watching heads up play and am trying to figure out preflop ranges.

Would they compatible to CO vs. Button in 6-max, as in mostly competitive ranges with OOP having more aces and button having more kings, etc? 99xx and 88xx closer in parity? OOP having more nut straights?

The Galfond-Jungleman HU has been interesting. Sometimes, Phil will say that Jungle should have some xx in a certain spot or his range and I’m not sure what to expect the range should be.

I'm assuming you're talking about HU cash games for 100BB stack sizes. Things will change depending on different variables including stakes. If playing low stakes, some hands become unprofitable for example. If it's HU SNGs, then I imagine limping for small stack sizes could be viable.

The other day I looked but I haven't been able to find specific HU ranges. This thread just gives %: https://forumserver.twoplustwo.com/3...-like-1803662/

I think it's a reasonable guess that 6max CO vs BTN is not going to be comparable. They're going to be playing significantly tighter and have different preflop strategies. BTN will be tighter vs a CO RFI than they would theirself as RFI vs the blinds.

BB defend vs BTN or SB RFI might be semi-comparable for the BB, but 6max SB/BTN RFI is likely much tighter than GTO HU. BTN RFI range would just be a starting point.

Ultimately, and this is very IMHO, granular preflop ranges may not matter as much due to how most likely no one is playing close to GTO PLO strategy. You still want to be playing tight from the BB due to positional disadvantage, and opening super wide from the SB to abuse having position. In practice, people are probably playing way too many hands OOP which is going to be your biggest edge, but this will also make their ranges stronger on a lot of boards---unless they're also 3betting specific hands, etc.

Very IMHO because I wouldn't consider myself a PLO expert, but no one else responded. Anyone thinks I'm wrong LMK.
