Alekhine Defense
Overview
Alekhine Defense is a specific line in the Semi-Open Games family (ECO B03), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
Play reaches this position via 1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4, after 7 plies of opening development.
The line refines Alekhine Defense, which traces back to the root opening King's Pawn Game.
The line splits into 4 documented sub-systems: Exchange Variation, Four Pawns Attack, Hunt Variation, and others.
In total, the branch covers 13 sub-variations across all depths.
