Bishop's Opening: Walkerling
3. f3?!
The Walkerling variation of the Bishop's Opening is a chess opening that begins with the moves 1. e4 e5 2. Bc4 Nf6 3. f3!?. This move is considered an obvious error by chess experts, as it weakens White's pawn structure and hinders the development of the king's knight, as well as weakening the kingside.
Black's main options are:
/3...Bc5/ develops the bishop to an active square that attacks f2.
/3...Nc6/ aims to activate both knights to active squares and control the center.
/3...d5/ strikes back in the center and fights for a lead in development, which black already has.
However, Black cannot play 3...Nxe4?, aiming to win a rook with 4...Qh4+, because white simply has 5. Kf1!, simply being up a piece.
