> Some moves in chess are only good moves if you get the next five moves exactly right, so they aren't suited to beginners.

This is important. Similar issue exists in StarCraft: good builds for pro players aren't necessarily good builds for regular players. If you can't macro behind double pronged harass, don't do it. If you can't watch your ramp to block adepts shading in, don't sit a probe at the top of your ramp

Don't say "I do this because experts do this", instead study it to understand why they do. Otherwise you're going to end up cargo culting

Better to do suboptimal well & with understanding than try do optimal poorly & be confused when it doesn't pay off
