Rat Defense: English Rat
Overview
Rat Defense: English Rat is a specific line in the Flank Openings family (ECO A41), 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.
It is reached after 4 plies of play, with the move sequence 1. d4 d6 2. c4 e5.
The line refines Old Indian Defense, which traces back to the root opening Queen's Pawn Game.
The line splits into 2 documented sub-systems: Lisbon Gambit, Pounds Gambit.
