Black sets up the famous Hedgehog formation with pawns on a6, b6, d6 and e6, creating a compact, flexible structure that resembles a hedgehog's spines. White builds up slowly with a typical English setup, while Black coils up before unleashing the thematic ...b5 or ...d5 pawn breaks. A deeply strategic system favoured by elite players.
