Another silly question, this should be the last one today.
Almost every time I solve the 4x4 cube I run into one of this PLL parities:
I follow
this guide to solve it, and as you can read there it says that the situation can be avoided almost 100% of the times, but it doesn't say how. I'm really interested in this, because the algs for that cases are just sick, and I don't see myself learning them anytime soon. ¿Do you know where can I finda guide or tips/steps to avoid that situation?
