Chess Tactics

Tactics are short-term sequences of moves that win material or achieve checkmate. Recognising tactical patterns is the single most important skill for improving at chess.

Forks

  • Knight Fork - A knight attacks two or more pieces at once. The opponent can only save one.
  • Bishop Fork - A bishop attacks two pieces along different diagonals simultaneously.
  • Rook Fork - A rook attacks two pieces along the same rank or file.
  • Queen Fork - The queen attacks multiple pieces using her combined rook and bishop movement.
  • Pawn Fork - A pawn attacks two pieces diagonally.
  • Royal Fork - A fork that attacks both the king and queen simultaneously.

Pins

  • Absolute Pin - A piece is pinned to its king and cannot legally move.
  • Relative Pin - A piece is pinned to a more valuable piece behind it.

Skewers & X-Rays

  • Skewer - The reverse of a pin. A more valuable piece is attacked and forced to move, exposing a less valuable piece behind it.
  • X-Ray Attack - A piece attacks through another piece on the same line.

Discovered Attacks

  • Discovered Attack - Moving one piece reveals an attack by another piece behind it.
  • Discovered Check - A discovered attack where the revealed attack is a check.
  • Double Check - Both the moved piece and the revealed piece give check simultaneously.

Removing Defenders

  • Removing the Defender - Capturing or driving away a piece that defends a key square or piece.
  • Deflection - Forcing a defending piece away from its defensive duty.
  • Overloading - Giving a piece too many defensive duties at once.

Other Tactical Motifs

  • Trapped Piece - A piece has no safe squares to move to and will be captured.
  • Interference - Placing a piece between two enemy pieces to disrupt their coordination.
  • Zwischenzug - An in-between move played instead of the expected recapture.
  • Attraction - Forcing an enemy piece to a vulnerable square.
  • Clearance - Moving one of your own pieces to open a line for another.
