Alright, so easy folds to 3-bets. Just about everything right now should be about range versus range for you. There will come a point in your poker evolution where range won't matter as much, and it will be much more about reads on opponents, and their postflop tendencies. However, I'd advise for now to think more about poker in relationship to showdown values. If you got to showdown, how would your hand stack up against your opponents range? It's important to have a firm grasp of this FIRST, before you get into fancy play syndrome. Once you understand this, and you know what your equity is going to look like in an equity calculator, then you I'd recommend moving to the next evolution of thought, but not before.
People have a tendency to want to skip levels of understanding. It's part of our nature to want to go from 0 to 100 and think we can do what experts in our respective fields (not just poker) can do right off the bat. The reality is though, that the ones who are really good had to go through these same evolutions, so just my personal warning... don't try to skip ahead too far. Just like you wouldn't start playing 32% of your hands pre-flop when you first started playing. You instead played really tight and learned how to properly bet, extract value, dump losing hands, etc...
Does anyone not know how to figure out opponents 3-betting ranges, or have any questions about this section before I move on to easy calls of 3-bets?
