Opening principles - Time

This is the last of a 3-lessons series about the generic principles of the opening that are Space, Time and Material.
The first post was about managing space in the opening, the second post was about material, both are aimed at beginners to intermediate players looking for sound opening pieces of advice.

How to avoid losing time making useless movers ?
How to protect your King as fast as possible?
How to buy time or space with material when the situation requires it ?
All the answers are in this post.

First advice: in the opening, make only one or two pawn moves, no more.
Developing your pieces is more important, and too many pawn moves will leave you behind in development.
