A rook placed on d8 serves to defend the d6-pawn and support its push to d5. Sometimes Black plays ...Bf8, ...g6, and ...Bg7 (or more simply ...Bf6 if f6 is vacant) to exert some influence over d4. Or the same bishop can be brought to c7 (via d8) to target White's
420:'hedgehog' was a generic term for any setup that was cramped, defensive and difficult to attack", but today refers specifically to this formation. The Hedgehog first became extensively analysed in the 1970s, when players began to appreciate the rich variety of strategic ideas that arose from it.

Once the basic
Hedgehog structure is in place, and depending on how White responds, Black has various ways of reorganizing their pieces. The knight on d7 often hops to c5, where it attacks a white pawn on e4; or to e5, where it attacks a pawn on c4. The knight on f6 can go to e8 (when Black placed

on c8 and e8 (or c8 and d8). Although Black's position is cramped, it has great latent energy, which may be released if Black is able to play ...b5 or ...d5 at some point. These pawn breaks are particularly effective because White usually places pawns on c4 and e4 (the
