The opening to a game of chess can be intimidating, an immeasurable expanse of potential where a single blunder can lead to a tough middlegame. But success at the opening is not learning move lists ad infinitum. It’s a matter of looking and adhering to three rudimentary principles: control of the center, development of pieces, and safeguarding of the king. By following these “golden rules,” players at any skill level can navigate through the initial going with purpose, laying the foundation for the rest of the game.
Central Control
The most important of these is to control the center. The middle squares—e4, e5, d4, and d5—are the most powerful squares on the board, having the most influence and mobility. Your initial actions should be to capture a foothold in this important sector, typically by moving the e- or d-pawn. Dominating the center provides your pieces with greater room to maneuver, confines your opponent, and offers a base from which to attack. Failing to control the center will result in a passive and close position, in which your pieces have no function to perform.
In this position, both players have moved their e-pawns to the center, fighting for central control.
Piece Development
The second of the golden rules is development. Your major pieces and your minor pieces are stranded on the back rank when the game starts. Development is getting your pieces—your knights, your bishops, then your rooks and your queen—onto active squares where they can play a role in the fight. A good plan is to develop your minor pieces first, directing them towards the center. It is generally most advisable to advance knights in front of bishops, as the knights’ best squares will be more obvious early on. Also, don’t move one piece twice during the opening, and don’t bring out your queen early since it will get attacked by your opponent’s developing pieces.
In this position, both players have developed their pieces. However, their kings are uncastled and prone to attack.
King Safety
The final rule, and perhaps the most significant rule for survival, is king safety. The ultimate goal of chess is to checkmate the other king. It is useless to have a good position if your own king is exposed and vulnerable. The best way to protect your king is by castling early on. Castling performs two beneficial functions: it moves your king from the vulnerable central files and activates one of your rooks. A middlegame uncastled king can be put at risk of being a target for your opponent’s advancing attack. While the most widely used, real king safety is about minimizing threats and creating a strong defensive structure, often with an interposing pawn shield.
Now the kings have castled and both players are entering the middlegame.
These three concepts work together. Control over the center is what gives strength to your developing pieces. Therefore, your development frees your king to seek refuge through castling. To break one may put the rest in jeopardy; like developing the pieces too quickly without regard to king safety, leaving yourself open to an attack. By internalizing and prioritizing these three golden principles—center, development, and king safety—you can always begin your games on the right footing, converting the opening phase into one of confidence and strategic foundation for victory.
