Develop your pieces to reasonable positions, especially if you are not familiar with your opponent's opening or defense. For better chess, place your pawns in the center quickly to release your other pieces and restrain your opponent's pawn and piece development.
Develop quickly towards the center to protect and attack the central squares.
Develop a piece with a threat when possible that your opponent must try to defend.
Develop your pieces first on the side where you intend to castle. That is usually the King's side. To improve your game, once you have gotten your Knights and Bishops out (the minor pieces), you may want to castle, then place a Rook on an open file if possible. Lastly develop your Queen, but not too early and not too far away from the protection of your pieces.
Develop your Bishops, Rooks, and Queen to threaten more distant targets. Try to move each piece once in the opening so as not to waste tempo or leaving other pieces undeveloped.
