🧩 The Complete Chess Tactics Glossary: 60+ Essential Patterns

An aggressive action attempting to win material, checkmate the King, or create weaknesses. The basis of all tactics.

A tactical motif where you lure (or force) an opponent's piece onto a vulnerable square where it becomes a target for a follow-up tactic.

A checkmate delivered by a Rook or Queen on the 8th rank because the King is trapped behind its own pawns (often fixed by making luft).

Lining up two or more pieces on the same file or diagonal to multiply their attacking power.

• Alekhine's Gun: A powerful triple battery: two Rooks stacked behind a Queen on a file.
• Queen + Bishop: The classic diagonal battery for delivering checkmate on g7 or h7.

Moving a piece (often with a sacrifice) solely to vacate a key square or open a line for a more powerful piece.

See Attraction. Luring an opponent’s piece onto a square where it becomes vulnerable to a tactic.

Forcing a key defender away from an important square or duty. Once the defender is deflected, the main target falls.

French for "in take": leaving a piece unprotected or insufficiently guarded so it can be captured for free.

The fastest possible checkmate (2 moves), occurring if White foolishly pushes their f- and g-pawns immediately.

A move that limits the opponent’s options. The hierarchy of forcing moves is: Checks, Captures, and direct Threats.

See En Prise or Loose Piece. Beginner slang for leaving a piece unprotected so it can be captured for free.

Slang for attacking an advanced enemy piece with a pawn to force it to move away (e.g., playing h3 to "kick" a Bishop on g4).

See En Prise. An undefended piece subject to tactical exploitation (LPDO: "Loose Pieces Drop Off").

Pieces cooperating to cut off all escape squares and trap the King, leading to an unavoidable mate.

Spotting familiar tactical structures and mates quickly without having to calculate everything from scratch.

Capturing, deflecting, or distracting a piece that is guarding a key target.

A quick 4-move checkmate idea targeting the weak f7 square with a Queen and Bishop.

Weakening the base of a pawn chain or removing a key structural defender.

Attacking a piece or square "through" another piece. This is the core geometric concept behind pins and skewers.

A defensive miracle where one of your pieces protects another piece "through" an enemy piece that stands between them.

One piece attacks two or more enemy pieces at the same time. The Knight is the most famous forking piece.

A simultaneous attack on two targets. Often synonymous with a Fork, but can also refer to creating two distinct threats (like threatening mate and capturing a piece).

A situation where a piece cannot (or effectively should not) move because it shields a more valuable piece behind it.

A piece is pinned to the King. It is completely illegal to move the pinned piece.

A piece is pinned to a valuable target (like a Queen). Moving it is legal, but will result in a severe material loss.

A rare situation where a piece is pinned from two different directions simultaneously (e.g., vertical and diagonal). It is completely paralyzed.

The "Reverse Pin." You attack a highly valuable piece (like a King or Queen), forcing it to move away and exposing a lesser piece behind it to capture.

Moving one piece to unmask an attack from a piece standing directly behind it. The moving piece can often capture or threaten freely while the opponent deals with the newly revealed threat.

A powerful variant where the unmasked piece delivers a check to the enemy King, forcing a defensive response immediately.

The most devastating move in chess. The King is attacked by the moving piece AND the unmasked piece simultaneously. The King must move; it cannot block or capture its way out.

A devastating sequence of repeated, alternating discovered checks (usually involving a Rook and Bishop) that mows down the opponent's pieces along a rank or file.

Giving up material intentionally to gain a stronger attack, initiative, or other overwhelming compensation.

The classic Bishop sacrifice on h7 (or h2) to rip open the castled King's pawn cover. It requires a Knight and Queen ready to jump into the attack immediately.

Sacrificing a piece simply to destroy the defensive wall of pawns protecting the King, leaving him naked against heavy attacking pieces.

When a piece is trapped and doomed to die anyway, it sacrifices itself to cause the maximum possible damage (e.g., capturing a pawn or minor piece) before it is removed.

Giving up a Rook (value 5) for a minor piece like a Knight or Bishop (value 3) to gain deep, long-term strategic or attacking compensation.

Sacrificing material to drag the enemy King out of safety and chase it across the board into a mating net.

A checkmate pattern where two rooks invade the 7th rank (the "pigs") and devour the opponent's pawns and King.

A defensive swindle tactic. Forcing a draw by checking the enemy King endlessly when you are otherwise losing material.

A pointless check delivered by a losing player that delays the game by one move but doesn’t change the inevitable outcome.

Deliberately putting your King in a position where it has no legal moves, then repeatedly sacrificing your last mobile piece (The "Mad Rook") with checks to force a draw.

A clever trick or resource utilized from a completely lost position to save a draw or unexpectedly win the game.

A King maneuver used to "lose a tempo" and pass the turn to the opponent, forcing them into Zugzwang.

Promoting a pawn to a Knight, Rook, or Bishop instead of a Queen. This is usually done to deliver an immediate Knight fork, a checkmate, or to avoid accidentally stalemating the opponent.

Sacrificing one or two pawns in a locked structure to forcibly create a Passed Pawn that cannot be stopped from promoting.

A geometric checkmate where a Knight traps the King against the board edge while a Rook delivers mate on the open file.

A classic checkmate pattern delivered by a Rook and Knight working in unison to trap the King in a corner.

A forced sequence of moves (often involving a sacrifice and multiple tactical motifs) that results in a clear advantage or checkmate.

A tactical motif where a King is trapped along a long diagonal and mated by a Bishop or Queen, with escape squares blocked.

Blocking an incoming check with a piece that also simultaneously delivers a check to the opponent's King. It usually forces an immediate trade of pieces.

Capturing an enemy piece with a piece that was currently under attack, thereby winning material and escaping to safety in one motion.

Placing a piece on a square where it physically cuts off the line of communication or defense between two enemy pieces.

A situation where a single defender is given too many jobs at once. If you remove or attack one of its duties, the defense collapses.

Aggressively advancing multiple pawns on one wing to rip open lines and attack the enemy King (common in opposite-side castling).

Lifting a rook in front of its own pawns (often to the 3rd or 4th rank) so it can swing horizontally across the board to join an attack on the flank.

A beautiful Knight checkmate where the King cannot escape because it is completely blocked in (smothered) by its own friendly pieces.

A provocative sequence designed to bait the opponent into making a natural-looking error that loses material or leads to mate.

Restricting an enemy piece by controlling all its flight squares, effectively dooming it to be captured.

German for "In-between move." Instead of playing the expected recapture immediately, you insert a surprise check or massive threat first to improve your position.
