Three rules that cover every opening
Every opening is a negotiation over the center. Three principles apply in all of them, before any theory: put a pawn on e4 or d4 to claim space; develop your knights and bishops toward the center before moving the same piece twice; and castle before move ten so your king is safe and your rooks are connected. The 12 openings below are the most-played in rated games on Lichess, drawn from over 1.5 billion games. Each row gives you the first three moves, the strategic idea in one sentence, who it suits, and the win rate for White, draws, and Black at the 1600 to 2500 rating band.

Open games (1.e4)
White plays 1.e4, Black replies 1...e5 or challenges immediately. The board opens quickly, tactics appear early, and piece activity matters more than pawn structure. These are the most-played positions in the game.
