Chess Openings

Introduction

At the start of a chess game, white's and black's pieces are placed on opposite sides of the board, not doing a lot except blocking each other's way.

The goal of the first few moves, the opening, is thus to:
  • Establish control over the central squares of the board, before your opponent does.
  • Move pawns forward to open up lines for pieces and create space for maneuvering.
  • Improve pieces by developing them to squares where they have higher mobility.
  • Provide better protection of the king, often by castling (putting king behind rook).

Here's an example of how white would like to setup his pieces in the opening:

White is completely winning!
Full control over the center. Castled king.
Large space advantage. All pieces developed on great squares.

The tricky part, of course, is that your opponent is also trying to do all these things, which makes your job a delicate balance between fulfilling your own plans and disrupting your opponent's.

Opening Names

The merits of different sequences of opening moves have been studied for hundreds of years. Most of the commonly reoccurring lines have received names, often based either on the name of the first master that studied or played it extensively (Ruy Lopez, Réti Opening, Englund Gambit), or a geographical location where it was played one or more times (London System, Vienna Gambit).

Below, let's take a quick look at the first few moves in one of the oldest and most popular chess openings, the Ruy Lopez opening.

Other Popular Openings Arising From 1. e4

Moving the e-pawn two steps forward like in the Ruy Lopez is by far the most common way to start a chess game: out of billions of games on the chess platform lichess, 62% have started this way. Let's look at some of the most common e4-openings.

Italian Game

In the Italian Game, white plays the bishop to c4 instead of b5. This is one of the oldest and most popular chess openings and one that is often recommended for beginners.

The Italian Game.
Black typically responds with one of: 3...Bc5, the Giuoco Piano (Italian for "Quiet game") 3...Nf6, the more aggressive Two Knights Defense.

Sicilian Defense

In the Sicilian Defense, black has opted to play 1...c5 instead of 1...e5, with the same goal of controlling the d4 square. This opening often leads to white and black castling on opposite sides, and sharp attacking games.
