The “sodium attack” is an opening-class concept rather than a universally standardized, single move-order opening in mainstream databases. In practice, it refers to a sharp, kingside-oriented attacking setup where White commits pieces and pawns to launch an initiative against Black’s king—often by forcing Black to respond to threats before completing development. Because the exact defining move sequence is not consistently documented under this name across sources, the most reliable way to identify it is by the characteristic attacking position and the commitment to an early initiative rather than by one fixed first dozen moves.

To spot a sodium attack in your games, look for the moment White (or the side using the concept) has both (1) enough development to attack immediately and (2) a concrete threat—typically a direct kingside pressure that makes Black’s defensive moves urgent. Using it well means you should time the pawn/figure thrusts so they create tactical targets (king safety, pinned pieces, or forced exchanges), not just “attack for attack’s sake.” If you’re studying it from puzzles, focus on the transition from setup to threat: the sodium attack is recognized by the point where Black must respond to a specific attacking plan, not by the opening moves alone.
