Castling
The move that hides the king.
What is castling?
Castling is a special move where the king and a rook move at the same time. The king moves two squares toward a rook, and the rook jumps over to the square right next to the king, on the other side. It tucks the king into safety and brings the rook toward the center.
Two kinds
| Kingside (short) | King e1→g1, rook h1→f1. Written O-O |
|---|---|
| Queenside (long) | King e1→c1, rook a1→d1. Written O-O-O |
When you may NOT castle
- The king or that rook has already moved
- There are pieces between the king and the rook
- The king is in check right now
- The king would pass through or land on an attacked square
How to do it
Always touch the king first and move it two squares, then move the rook. In tournaments, touching the rook first can count as a rook move.
Tip
💡 Castle early — usually in the first 10 moves. A king left in the center gets into trouble.
✏️ Practice: your turn
- Practice kingside castling for both colors
- Practice queenside castling
- Set up a position where castling is not allowed and explain why
