While I've been playing, I've noticed a lot of players with 12%+ 3bet, some as high as 20% and I'm definitely folding too much to them. So I'm trying to work out how to build my own ranges with which to call and play back, but I'm not 100% sure how. It makes sense to look at the range vs range strength and find one where I'm ahead but re-stealing enough to make it unprofitable, or to be ahead when calling.
Obviously in this situation we're light 4betting a bit because we expect them to fold enough with their wide 3betting range and playability post-flop would be a factor if called, what other factors do you consider/what is your study approach?
