Attacking the King · Yatish Chandra Shukla

Attacking f7 and f2

The weakest square in the camp

In this lesson you will learn

  • Why f7 (and f2) is a natural target
  • Typical sacrifices: ♗xf7+, ♘xf7 and ♕xf7+
  • Attacks along the open f-file after castling
  • How the king is drawn out and hunted

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.

NoteThe king that is drawn to f7 stands on the open f-file and on the diagonals a2–g8 and h5–e8. Look for a rook on f1, a bishop on c4 and a queen on h5 — they all hit the same square.
LessonWhen your pieces aim at f7, ask what happens after a sacrifice there: can the king be chased into the open? Is there a fork or a discovered check?

Remember

  1. f7 and f2 are protected only by the king at the start of the game.
  2. Bishop on c4, queen on h5 or f3, knight on g5 or e5: all aim at f7.
  3. A sacrifice on f7 drags the king into the open, where checks follow.
  4. After castling, the open f-file keeps f7 a target.
