Okay this concept is interesting.
Your bet sizing is based off what part of your opponent's range you are putting in 0EV spots.
When the 2tone flop turns into a 4 flush runout. Some of the flushes that are 0EV to a jam now always bet when OOP checks.
That makes us incentivized to check more nutted hands to IP.
GTO uses so many sizing's on these runouts because it's targeting all different hand classes but if you simplify it and break it down it becomes a lot easier to understand.
Let's say it's a SB3BETvsBTN spot. And we decide to choose a standard sizing structure on the FCT so B25/B33/river we use 2 sizings so B33/Jam
Flop is A
K
9
5
OTT
2
OTR
You never bet AxQc/AxJc/AxTc
My reasoning is because all the EV comes from inducing bluffs. Also if you jam you put weaker flushes in 0EV spots but if you check the weaker flushes always value bet so you win from both hand classes.
You value own the weak flushes and you induce vs the bluffs so that means we check all nutted hands OTR that block calls. AxQc never bets but QxQc does.
