Hi, I have read all the donkr PLO from scratch articles and many 2+2 threads, but I still have some questions about how GTO cbetting ranges are constructed.

1. edit: answered - When ip we use a polarized betting range (value/PLO-air/air) where we check back hands (from the middle of our range) that profit from free cards and that cannot stand a check/raise. Oop we cannot check back, that is why we include the check back hands in our cbetting range and skip cbetting with the bottom (air) of our range. We just check/fold our worst hands. Did I get this right?

2. edit: not answered yet - board: AK5 rainbow

I open a tight (UTGish) and a loose (BNish) range and get called from nemesis who is sitting oop in the blinds. Having my tight range I can construct my cbetting range in a well balanced fashion that I am able to defend vs check/raises (with TopTwo+) and vs opponent betting out OTT/OTR after I checked behind flop. That is because I have enough strong hands in my range.

The part where I have questions is when I open the loose range. My value combos drop drastically and my cbet % would go down below 30% if I wanted to keep my ch/r defending range of TopTwo+. Do we

a) widen our defending range vs check raises to lets say TP+GS+ for example? This would allow us to keep a higher cbet frequency. The underlying assumption is that nemesis knows our opening range and defends wider vs cbets as if he would have done against a tighter opening range. Is this assumption valid?

b) just cbet very rarely? This weakens our check back range because there is a lot more air in it now.

c) not cbet at all to strengthen our check back range? note: This seems very sick on this board from a traditional non GTO point of view.

3. edit: I think is answered, but feel free to comment - If we are ip and cannot cbet/defend/check back balanced anymore because our opening range is too wide, where do we make the first cut? Do we check back more PLO air (bare MP for example) or is it better to skip cbetting the very bottom of our range and check back all the pure air first?

I know there are some GTO gurus out there. Your help is appreciated.

edit: I fear the discussion might drift towards "You do not need this in low stakes.." "This situation does not come up frequently.." "This is not the most +EV play.." answers. That was not the question. I am aware that "nemesis" (the GTO one) will almost never be met and that it is common playing style to take an exploitive line. The purpose of this thread is to get an answer how the GTO range is built. The AK5 board is just an example to explain my situation. Once I get explained how I can properly manage my loose range (or tight range on boards that completely miss me) in a balanced fashion generally I can do this for any board on my own.
