Apart from a lot of the solved preflop GTO ranges that are widely available, how do you guys go about formulating ranges that exploit your pool?

For example: If pool on the BU opens X% and they fold to 3b X% of the time and we're in BB, what is our range?

I've used different tools such as HoldEq (with Flopzilla) and Holdemviewer while calculating ranges that work well when calling 3bets and balancing our 4betting range, but having trouble figuring out the best way to construct a lot of SRP spots. This of course is disregarding a lot of heuristics that can come up in-game but more from a technical standpoint to get more accurate database solutions.

Thank you!
