Frequently Asked Questions (F7)
Why is f7 the weakest square on the chessboard?
The f7 square (and f2 for White) is the weakest square in the starting position because it is defended ONLY by the king. Attacking f7 with a bishop and queen (Scholar's Mate) or knight (Fried Liver Attack) can force early checkmate or win material.
How do you defend the f7 square in chess?
To defend f7, develop your knights to f6 or e7, push ...d5 to block attacking bishop diagonals, or castle kingside (O-O) so your rook on f8 defends the f7 pawn alongside the king.
What openings attack the f7 square?
The Italian Game (3.Bc4), Ruy Lopez, Fried Liver Attack (4.Ng5 d5 5.exd5 Nxd5 6.Nxf7!), Alien Gambit (5.Nxf7!), and Scholar's Mate (Qh5 + Bc4) all target the f7 square.
