Castling and King Safety
Learn the significance of castling and the importance of ensuring king safety.
Castling Rules
Castling is a special move that moves the King and Rook simultaneously.
There are kingside castling (short castling) and queenside castling (long castling).
Castling moves the King to a safe position while activating the Rook.

Castling Conditions
Several conditions must be met to perform castling.
Neither King nor Rook has moved, King is not in check, no check along King's path, no pieces between King and Rook.
Castling is only possible when all these conditions are satisfied.

Kingside vs Queenside
Kingside castling (O-O) moves King to g1 (or g8) and Rook to f1 (or f8).
Queenside castling (O-O-O) moves King to c1 (or c8) and Rook to d1 (or d8).
Kingside is faster to execute, while Queenside provides better Rook activation.

Strategic Value of Castling
Castling is an important part of development, achieving King safety and piece harmony simultaneously.
Early castling is generally recommended, moving the King to safety in preparation for central battles.
After castling, Rooks are connected, King-side defense is strengthened, and preparation for middlegame is complete.
