# Learning ranges/equity calculation and using combos

Red Chipper Posts: 2 ✭✭
Hi guys!

I am trying to set some equity % learning plan.
Please let me know if my idea is right:

Example (ranges may be abstract but it is just to give an example):

I am assuming that I am playing on BB with range: 99+, AJs+, KJs+, QJs, AQo+, KQo
Villian is raising on BU and I know that his raising frequency from this position is 15%.
So I need to know how my range works against 15% of all possible hands, which in theory are: 77+,A7s+,K9s+,QTs+,JTs,ATo+,KTo+,QJo

This particular situation gave me 58% against 42% equity.

I would need to remember all combinations of my position ranges vs villian’s typical 5%, 10%, 15%, 20% ranges etc.

Does it make sense to make some entry calculations? Or does it make my gameplan too easy to read? Is there any better training form to get this organised?

Also, what about eqity after Preflop? There are too many possible card combinations to be able to calculate equity on the flop everytime. So unless I am drawing, I am still basing on preflop equity calculations?
And how can I convert combos calculations into equity boost/downgrade?
Or in general, how knowing possible combos combinations can help me making decisions, as I undestand how to calculate combos depending on villian’s range, but I am not sure what should I make with results 🙂

I hope it's not too much :D

Best!
