The Réti Opening with 1...Nf6 arises after 1.Nf3 Nf6. ECO code: A05.

Overview

The symmetrical knight development is one of the most common responses to 1.Nf3. Black mirrors White's approach, developing a piece without committing to a pawn structure.

Main Lines

After 1.Nf3 Nf6, the game's character depends on White's next move:

• 2.c4 – Entering English Opening territory.

• 2.g3 – The King's Indian Attack setup, continuing with Bg2 and d3.

• 2.d4 – Transposing into Queen\'s Gambit or Indian Defence systems.

Strategic Themes & Plans

Both sides maintain maximum flexibility. The game can transpose into virtually any standard opening depending on subsequent choices. This position is one of the most important crossroads in opening theory, as it precedes many of the most commonly played chess openings.
