Taken from Chess Pathways - Chess Openings
Studying chess openings is essential for players at any level. It helps you understand the purpose of each move and sets the stage for a successful game.
These fundamental principles will guide your opening play:
Control central space with your pawns: Controlling space gives your pieces room to manoeuvre and denies squares to enemy pieces.
Castle early: This move keeps your king safe and connects your rooks, which is important for contesting open files in the middlegame.
Develop your pieces: Get your pieces into the action as quickly as possible.
Don't move the same piece twice without a good reason: This ensures that you don't fall behind in piece development.
Don't make unnecessary early queen moves: Develop knights and bishops before the queen to avoid having her harassed by enemy pieces.
Strike while the iron is hot: If you have a lead in development, act quickly to open the centre and start a tactical skirmish before your opponent catches up.
Safety first: Always consider the safety of each move and avoid making unsafe moves that allow your opponent to win free material.
Chess opening study can be divided into two main categories:
Learning Opening Principles: Mastering these principles alone will give you a significant advantage over your opponents.
Memorising Specific Opening Moves ("Opening theory"): This requires memorising specific sequences of moves, which can be helpful for more advanced players.
Remember that understanding the plans associated with each opening is a significant advantage at any level of chess.
