The Four Knights Game is a chess opening that begins with the moves:

1. e4 e5
2. Nf3 Nc6
3. Nc3 Nf6

This is the most common sequence, but the knights may develop in any order to reach the same position. The Four Knights usually leads to quiet positional play, though there are also some sharp variations. The opening is fairly popular with beginners who strictly adhere to the opening principle: "Develop knights before bishops." One of its practical advantages is that it can be played in response to the Petrov's Defense: after 1. e4 e5 2. Nf3 Nf6 3. Nc3, Black's best move is 3...Nc6.

The Four Knights was one of the workhorses in the family of the Open Game, at even the highest levels, until World War I. Thereafter it fell by the wayside, along with several other Open Games. In this period ambitious players explored the Ruy Lopez, believing it a better attempt by White to exploit the advantage of the first move. In the 1990s, this opening saw a renaissance and is now seen in the praxis of players from beginner to grandmaster.
