# how to filter/study Population's reactions more efficiently

Hi guys,

I was wondering if there is easier/more effective ways to study how people react to certain actions i take.

A very simple example:

For example i openraise BTN and i want to see how often i get 3bet on average. What i can do is i filter for "hands where i open the button" and lets say it shows 100 hands. then i filter "i open the BTN and i faced a 3bet" and the result shows 10 hands, which means i get 3bet 10% of the time i open my BTN. There HAS to be a more efficient way to do this.

Or, example number 2, i wanna see how often people fold to my x/r on the flop. i will have to filter "hands where i x/r" and it shows me 100 hands again. and then i filter "hands where i x/r and a) we see a turn or b) i x/r/f" to only filter out the times they fold. not it will show 60 hands so i know they folded 40% of the time.

This is a very hard way to achieve something very easy, and theres many more examples where i feel like i have to take this complicated route to get the results i want.

any tips?

Thanks :)
