Alekhine Defence
MICOS Opening Group B09.AL – Alekhine’s Defence begins with 1.e4 Nf6. This hypermodern defence invites White to advance the central pawns, allowing White to build a broad pawn centre while Black develops the knight and avoids immediately occupying the centre with pawns. Black’s strategy is to challenge and undermine White’s advanced pawn structure later with well-timed attacks and pawn breaks.
The resulting positions are often asymmetrical and can become strategically complex, making Alekhine’s Defence attractive to players seeking active counterplay and fighting positions from an early stage.
