- Begin with 1 e4 or 1 d4, either of which moves releases two pieces.
- Anchor at least one pawn in the center and give it solid support.
- Whenever feasible, bring out your knights before the bishops.
- Of two developing moves, select the more aggressive one.
- Move each piece only once in the opening.
- Move at most two pawns in the early stages of the game. Play with the pieces.
- Develop the pieces with a view to controlling the center, either by occupying it or bearing down on it from a distance, as fianchettoed bishops do.
- Develop the Queen, but close to home to avoid her being harrassed by pawns and minor pieces.
- Do not chase after pawns at the expense of development.
- Secure the safety of the King by early castling, preferably on the kingside.
