13.1 Open the Centre!
A king that stays in the centre is safe only as long as the centre is closed. As soon as the central pawns are exchanged, files and diagonals open towards it, and the king has no pawn shelter of its own. The rule for the attacker is simple: if the enemy king is still in the centre, open the position — even at the cost of a pawn or a piece.
Typical weapons are pawn breaks such as d5 or e5, piece sacrifices on e6 or d5, and a rook on the e-file that pins whatever stands in front of the king.
13.2 Time Matters More Than Material
Against a king in the centre, development decides. Count the pieces each side has brought into play. If you are two or three moves ahead, a sacrifice that opens lines will usually work, because the defender has no time to castle or to bring the pieces over.

- Use pawn breaks and sacrifices to open the e- and d-files.
- Development counts more than material in these attacks.
- Checks gain time and stop the king from castling.
