Chess Principles Introduction

This article is an introduction into Chess principles during the different stages of the game.

The Opening

The opening is considered complete, when the rooks are connected.

Opening Principles

1. Develop
   1. Use all pieces for your game
   2. Improve position by expanding it
2. Develop: Bring out minor pieces
3. Develop: Connect the rooks
4. Develop the pieces towards attacking the center
5. Never move a piece twice within first 10 moves
6. Castle the King within first 10 moves if not within first 7 moves

These are not necessarily the best moves, but these are solid principles to achieve a good position without memorizing openings.
