1) Lesson: how the king moves in chess

Basics

The king is the most important piece in chess. It moves only one square, but it can do so in every direction. However, you may not move it into check, place it next to the opponent king, or castle when all conditions are not met.

King movement

A king does not jump and does not move far.

A king moves one square.
It can go in every direction: forward, backward, sideways, and diagonally.
It cannot jump over pieces or make a normal two-square move.

Forbidden squares

A king must always remain safe.

A king cannot move onto a square attacked by an opponent piece.
A king cannot remain in check after making a move.
Two kings cannot stand next to each other, because they would attack one another.

Captures

A king captures the same way it moves.

A king can capture an opponent piece standing one square away.
After capturing, it still must stand on a safe square.
It cannot capture a piece if that would put it into check.

Castling

This is the king’s only special move.

In castling, the king moves two squares toward the rook, and the rook jumps to the square next to the king.
Castling is possible only if the king and that rook have not moved yet.
There may be no pieces between the king and the rook, and the king may not be in check, pass through an attacked square, or finish on an attacked square.

The most important thing to remember: a king does not move far, but every move it makes must be safe. It is the king’s safety that determines whether a move is legal.

Reinforce the lesson in practice

After working through the material, the best next step is to go to a game and practise king movement, avoiding check, and castling on a real chessboard. Practice is what reinforces safe decisions best.
