Okay so I am still digging into this Front door Flush complete vs Backdoor Flush complete phenomenon in Triple Barrel spots. I ended up asking Tombos (Tom from GTO Wizard) about this and he looked at some GTO bots to see how Theory actually arrives at the river.
He sent me some pictures and he allowed me to share them with you guys.
BTNvsBB SRP 100bb. When BTN bets river they have the same amount of weak hands in range so theoretically there is no difference between a Front door flush complete and a backdoor flush complete.
Front door Flush Complete:
Back door Flush complete
Both are 31 weak here.
But something interesting happens in B-B lines or when BTN arrives to the river after double barreling.
Theoretically, GTO has more weak hands on Front Door Flush Complete boards as opposed to Back Door Flush Complete boards:
Front Door Flush complete:
39% weak
Back Door Flush complete:
36% weak
So the pet theory here is the reason population is weaker on Front door flush completes is because they don't compensate OTR for this weaker range. If you arrive to the river with a weaker range than normal (i.e. Front door flush draw complete) you are supposed to give up more but population is not doing that.
Big shout out to Tombos21 for the sims/pictures and helping me understand this subject better.
