Preflop exploitative ranges

Hi,

Anyone know what would be the best and cheapest (or cost efficient) way to study how we should be adjusting, for an example, our opening (and 3bet and 4bet etc.) ranges and sizings against villains with exploitable pre ranges? I do know there are many heuristics we can use against players who 3bet too much, 4bet too tight or don't defend blinds aggressively enough, but I'd actually like to start digging a lot deeper into these spots on my own.

Any recommendations?

Thanks in advance!
