Trompowsky Attack: all variations and ECO codes

10 named lines across 1 ECO code (A45). Source: the CC0-licensed lichess.org opening database.

The idea

White pins the knight before Black can even choose a defense, sidestepping the entire body of King’s Indian, Nimzo-Indian, and Grünfeld theory in one move. It’s a practical weapon built more around avoiding a well-prepared opponent than any deep structural advantage of its own.
