9.1 A Square With One Guard
In the starting position every square in front of the king is protected by at least one piece — except f7 (and f2 for White), which only the king defends. That makes it the first target of beginners and grandmasters alike. A bishop on c4 and a queen or knight joining it are enough to create threats on f7 in the first few moves, as we saw in Chapter 6.
The weakness does not disappear after castling. The f7-pawn is still close to the king, and when the f-file is opened a rook on f1 can join the attack. A piece that lands on f7 often attacks the queen, a rook and the squares around the king at the same time.
9.2 Three Typical Sacrifices
1. ♗xf7+ — the bishop gives check and drags the king forward. After
♔xf7 a knight check on g5 or e5, or a queen move with check, often wins back the material with interest.
2. ♘xf7 — the knight forks the queen on d8 and the rook on h8, or
opens lines towards the king.
3. ♕xf7+ — the queen lands on f7 supported by a bishop or knight;
with the king boxed in, this is often mate at once.
9.3 Worked Examples

Example 9.1
Black to move. Find the mate.
Find the key move.
Solution. 1...♕xf2+ 2.♔h2 ♖h6+ 3.♖h4 ♖xh4# — the final position is two heavy pieces working on neighbouring lines, one cutting the king off and the other giving check.
Example 9.2
White to move. Find the mate.
Find the key move.
Solution. 1.♕xf7+ ♔h8 2.♕e8+ ♗f8 3.♕xf8# — the final position is a back-rank mate: the king is shut in on its first rank by its own pawns.
Example 9.3
White to move. Find the mate.
Find the key move.
Solution. 1.♕f7+ ♔h8 2.♕e8# — the final position is a back-rank mate: the king is shut in on its first rank by its own pawns.
Example 9.4
White to move. Find the mate.
Find the key move.
Solution. 1.♕xf7+ ♔xh8 2.♕f8# — the final position is a back-rank mate: the king is shut in on its first rank by its own pawns.
Example 9.5
White to move. How should the attack continue?
Find the key move.
Solution. 1.♗xf7+ ♔xf7 2.♘g5+ ♔e7 3.♕xg4 — White wins material and keeps the attack.
Example 9.6
Black to move. How should the attack continue?
Find the key move.
Solution. 1...♖xd3 2.f6 ♖d4 3.f7 ♖f4 — Black wins a piece.
Remember
- f7 and f2 are protected only by the king at the start of the game.
- Bishop on c4, queen on h5 or f3, knight on g5 or e5: all aim at f7.
- A sacrifice on f7 drags the king into the open, where checks follow.
- After castling, the open f-file keeps f7 a target.
