Overview

Old Indian Defense: Normal Variation is a named branch in the Flank Openings group of chess theory, classified under ECO A55.

The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.

It begins with 9 plies and takes 1. d4 Nf6 2. c4 d6 3. Nc3 Nbd7 4. e4 e5 5. Nf3 to reach the canonical position.

In the opening tree, this line branches off from Old Indian Defense, part of the broader Queen's Pawn Game system.
