Keeping the following opening principles in mind will serve you well. Even when you begin memorizing specific sequences of moves, these principles are still crucial to playing the opening successfully – if your opponent plays a move you’re unfamiliar with, you’re back on your own, and these principles will be your lifeline!
Control central space with your pawns. Controlling space gives your pieces room to maneuver, and denies squares to enemy pieces.
Castle early. Once the center opens up, it will be dangerous for your king to be stuck on its starting square. Castling tucks your king safely away in a corner, and also allows you to connect your rooks – good for contesting open files in the middlegame! Castling? Click Here to see what this means.
Develop your pieces. Each player starts each chess game with eight pieces sitting lazily on their own back rank. You won’t win many games if they stay there too long. Make pawn moves when needed to control space, but have a sense of urgency in getting your pieces into the action.
Don’t move the same piece twice without a good reason. If your opponent methodically brings all their pieces into the game, while you move the same piece again and again, you’re going to fall behind in piece development.
Don’t make unnecessary early queen moves. If you do move your queen, make sure that she can’t easily be harassed by enemy pieces. There’s a good reason why knights and bishops are often developed before the queen – check out the video below to learn why!
Strike while the iron is hot! If you succeed in getting a large lead in development (especially if you’re castled and your opponent isn’t), you need to act quickly or your opponent will catch up! Open the center and start a tactical skirmish with your fully mobilized army, before your opponent’s troops have left their barracks.
Safety first. None of the above principles give you a license to make unsafe moves that allow your opponent to win free material. Carefully assess the safety of each move before making it – in chess openings and in ANY chess position. If your opponent violates this principle, capitalize on it, regardless of what the above principles say – after all, it would be silly to avoid capturing a free enemy queen because you don’t want to move the same piece twice in the opening!
Be cautious about exposing the “King’s Short Diagonal.”
