Here are 4 basic rules for your left hand - follow these and you will be able to play with ease and the whole fretboard will be accessible to you. You will be able to play with much less tension and much less effort!
Thanks for sharing how to move your left hand correctly when you want to move away from the fretted playing position and you don't want to land on the awkward fingers fretted playing position. I normally pivot the elbow first then move all my fingers to the position that I want to play.
