GTO Preflop ranges for HU with unusual open sizes

There are a number of constraints you would need to state in addition to the allowed opening sizings:

1. What rake structure (% and cap)

2. What allowed 3-bet sizings

3. What allowed 4-bet sizings

^ as a minimum and I could run this for you. Also, state what ranges you explicitly want to be shown (outputs).

1. 4% with 1.5bb cap
2/3. 3bet to 8bb for 2bb open and 4 bet to 20bb then 5bet allin. 3bet allin for 6.5 open.

I am most interested in the opening ranges to 2bb and 6.5bb, possibly some hands are a raise to either 2bb or 6.5bb based on a probability.

Also calling ranges for 6.5bb open to call an allin is interesting.

Feel free to make any other simplifying assumptions or base them on most common/standard parameters.

For the last question i am just wondering if 3bet% increases alot if you only have a small 3bet size from the bb. How high is the % for 2.666x 3bet? (Against opening only 2-3bb)

Thank you for taking the time

Tree settings are rake 4%, 1.5bb cap, small bucketing (for quicker solve)

SB can RFI: 2bb or 6.5bb or fold
---------------------------------------------------------------
->BB vs 2.0bb RFI can call, fold or raise to 8bb

-->SB vs BB 3b to 8bb after RFI 2.0bb can 4b to 20bb, call or fold

---> BB vs SB 4b to 20bb can 5b jam 100bb, call, or fold
----------------------------------------------------------------
->BB vs 6.5bb RFI can call or jam 100bb

-->SB vs BB 4b jam can call or fold

^ the main issue with the settings as you have them set up is that 3b jamming 100bb vs. 6.5bb rfi is not efficient at all. 3B sizing to 8bb vs. 2.0bb open is kind of small also.

I'll let it run for about an hour.
