Rat Defense: English Rat, Lisbon Gambit
Overview
Rat Defense: English Rat, Lisbon Gambit is a gambit, classified under ECO code A41 within the Flank Openings family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.
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 6 plies — specifically the moves 1. d4 d6 2. c4 e5 3. dxe5 Nc6.
It is a variation of Rat Defense: English Rat, which itself descends from the root opening Queen's Pawn Game.
