The Hedgehog System: Pawn Structure & Breaks
The Hedgehog is defined not by pieces, but by its unique pawn structure. By stripping away the pieces, we can clearly see the "skeleton" of the position: a solid defensive wall waiting to explode with thematic pawn breaks.
1. The "Spines" of the Hedgehog
White usually establishes a space advantage with pawns on c4 and e4 (the Maroczy Bind). Black counters this with a flexible wall of pawns on the 6th rank. These are the "spines" that control key central squares and prevent White from invading.
Fig 1: The pawn skeleton. The highlighted pawns form the defensive wall.
- The Wall (a6, b6, d6, e6): These four pawns work together to control the critical 5th rank (c5, d5, e5, f5).
- Flexibility: Because the pawns are back on the 6th rank, Black's pieces can shuffle freely behind them without creating weaknesses.
2. Thematic Pawn Breaks: Releasing the Energy
The "coiled spring" nature of the Hedgehog comes from the potential to shatter White's center with pawn breaks. Black patiently maneuvers until one of these breaks becomes powerful.

The Two Main Breaks
- The ...b5 Break: The most common plan. It challenges White's c4 pawn and fights for queenside control.
- The ...d5 Break: A central explosion. If White's control of d5 slips, this break can open lines for Black's rooks and queen straight to the White king.
