Opening a game wellStep 3 of 6

Castle early

One move that tucks the king away and brings a rook towards the centre. Do it early.

Your king starts the game in the middle of the board. That is the worst place for him: it is exactly where lines open when pawns get traded.

Castling fixes it in one move. The king goes to a corner behind three untouched pawns, and on the way your rook comes towards the centre. Two problems solved at once: the king is safe, the rook is in play.

Castle early. Not “once I have finished developing”, not “when it gets dangerous”. Early. Most beginner games are lost by a king left in the centre while the position opened around him.

Two rules to know:

  • You cannot castle if your king or that rook has already moved — even if it came back.
  • You cannot castle out of check, or through an attacked square. The rook, however, may cross an attacked square: it is the king that counts.

White has castled, Black has not. Look at the e-file: if it opens, the black king is staring at a white rook.
