Trompowsky Attack: Classical Defense
Overview
Trompowsky Attack: Classical Defense is a specific line in the Flank Openings family (ECO A45), arising from a recognised theoretical position.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
The line arises from 4 plies — specifically the moves 1. d4 Nf6 2. Bg5 e6.
The line refines Trompowsky Attack, which traces back to the root opening Queen's Pawn Game.
It continues primarily into one named line, Big Center Variation.
