Opening
From WikiChess
Opening is a term used to describe the beginning moves of each player in a game of chess. The opening is followed by the middlegame and the endgame.
[edit] Objective
The objective of an opening is to gain an early advantage. This is usually done by developing pieces (moving pieces to better squares), controlling the center (attacking e4, d4, e5, d5) and trying to dislodge your opponent from doing that.
[edit] Types of openings
There are several types of openings, each one reflecting the style of the player. Some may prefer to take the defensive with their pieces in their openings, while others will want to take the offensive.
