¤a3 Chess Openings

The Na3 Chess Opening are sometimes called the “Durkin Opening”. Also it is sometimes called the Sodium Attack from Na, the chemical symbol for sodium.

It is a rare and unconventional chess opening and hypermodern choice, aiming for flexibility and control over the central squares.

After 1. Na3, the opening can take various paths depending on Black’s responses. White may choose to fianchetto the bishop with g3, transpose into a different opening, or opt for other setups. The Durkin Opening doesn’t adhere to classical principles of immediate central pawn control but instead focuses on piece development and the potential for later pawn breaks.
