Tactics chess terms

Every tactics term, defined and illustrated.

Tactics
Arabian mate
The Arabian mate is a checkmate pattern in which a rook and a knight combine to deliver mate against a king trapped in a corner: the rook delivers the final check while the knight defends it and seals the last escape square.
Tactics
Attraction
Attraction in chess is a tactical motif that forces an opponent’s piece — most often the king or a major piece — to move to a disadvantageous square, where it becomes vulnerable to a decisive combination.
Tactics
Back rank mate
The back rank mate is a checkmate that occurs when a king is trapped on its back rank (the first or eighth rank) and is checkmated by an enemy rook or queen sliding onto that row.
Tactics
Battery
A battery in chess is a setup in which two pieces of the same color are aligned on the same line — a file, rank, or diagonal — so that the rear piece reinforces and amplifies the power of the front piece.
Tactics
Boden’s mate
Boden’s mate is a checkmate pattern delivered by two bishops whose diagonals intersect to trap the enemy king in a crossfire, typically following a sacrifice that opens the necessary lines.
Tactics
Combination
A combination in chess is a forced sequence of moves, often involving a sacrifice, that leads to a clearly favorable outcome — material gain, checkmate, or a decisive advantage — against the opponent’s best defense.
Tactics
Counterattack
A counterattack in chess is a response to an opponent’s threat that, rather than defending passively, creates an equal or greater threat in return, forcing the opponent to react.
Tactics
Damiano’s mate
Damiano’s mate is a checkmate pattern in which a queen drives the enemy king to the edge of the board through a series of checks, before delivering mate with the support of a pawn that seals off the king’s last escape square.
Tactics
Deflection
Deflection is a tactical motif that forces an opponent’s piece away from a square or line it is protecting, compelling it to move somewhere less useful — typically through a capture or an immediate threat.
Tactics
Discovered attack
A discovered attack is a tactical move in which one piece moves away and, in doing so, uncovers an attack by an allied piece that was sitting behind it on the same rank, file, or diagonal.
Tactics
Discovered check
A discovered check is a tactical device in chess where moving one piece reveals an attack on the opponent’s king by another piece that was previously blocked behind it on the same rank, file, or diagonal.
Tactics
Double attack
A double attack is a tactic that threatens two of the opponent’s targets simultaneously with a single move, forcing them to choose which one to save.
Tactics
Double check
A double check is a situation in which the opponent’s king is attacked by two pieces simultaneously in a single move — a special case of a discovered check where the moving piece itself also gives check.
Tactics
Epaulette mate
The epaulette mate is a checkmate pattern in which the enemy king is mated on a rank or file while two of its own pieces block both lateral escape squares — resembling the epaulettes on a military uniform flanking it on either side.
Tactics
Exchange sacrifice
The exchange sacrifice is a tactical or strategic decision in which a player voluntarily gives up a rook for a bishop or knight — that is, surrenders "the exchange" (the value gap between a rook and a minor piece) — in return for concrete compensation such as an attack, an improved pawn structure,…
Tactics
Favorable exchange
A favorable exchange in chess is a tactical or strategic operation in which a player captures an opponent’s piece of greater value than the one given up in return, thereby gaining a net material advantage.
Tactics

Tactics
Fork
A fork is a chess tactic in which a single piece attacks two or more enemy pieces at the same time, forcing the opponent to give up at least one of them.
Tactics
Greco’s mate
Greco’s mate is a checkmate pattern in which a rook (or queen) delivers check to the enemy king along the file it occupies, while a bishop controls the diagonal escape square, making any flight impossible.
Tactics
Interference
Interference in chess is a tactical motif that involves placing a piece on the line shared by two enemy pieces of the same color, severing their mutual coordination and exposing the weakness that results.
Tactics
Ladder mate
The ladder mate is an endgame checkmate pattern in which two rooks (or a rook and a queen) progressively drive the opposing king to the edge of the board by stripping away one rank or file at a time, until checkmate is delivered.
Tactics
Legal’s mate
Legal’s mate is a tactical combination in which a player sacrifices their queen to deliver checkmate using minor pieces — typically two knights and a bishop — by breaking a relative pin on the knight on f3.
Tactics
Mating attack
A mating attack is an aggressive sequence of moves aimed directly at checkmating the opponent’s king, by coordinating pieces to surround it and eliminate all escape squares.
Tactics
Overloading
Overloading is a tactical motif that exploits a piece burdened with too many defensive duties at once — typically protecting two pieces or squares simultaneously — so that it cannot fulfill both responsibilities at the same time.
Tactics
Perpetual check
Perpetual check is a tactical resource in which a player delivers an unending series of checks that the opponent’s king cannot escape, thereby forcing a draw by repetition.
Tactics
Pin
A pin is a tactic that restricts an enemy piece by forcing it to stay on its square in order to protect a more valuable piece or square behind it, under threat of material loss.
Tactics
Positional sacrifice
A positional sacrifice is the deliberate giving up of material — a pawn, a minor piece, or more — without an immediate tactical payoff, in exchange for lasting positional benefits: improved piece activity, control of key squares, prolonged initiative, or a superior pawn structure.
Tactics
Quiet move
A quiet move is a move that involves no capture, no check, and no immediately obvious threat — yet carries a decisive tactical or strategic idea.
Tactics
Sacrifice
A sacrifice in chess is a move in which a player deliberately gives up material — a pawn, a minor piece (knight or bishop), or a major piece (rook or queen) — in exchange for a different type of advantage: a decisive attack, a tempo gain, or a structurally superior position.
Tactics
Scholar’s mate
Scholar’s mate is a four move checkmate in which White targets the f7 square — the weakest point in Black’s starting position — using the queen and a bishop to deliver an instant finish.
Tactics
Skewer
A skewer in chess is a tactical device in which an attacking piece targets a high value enemy piece, forcing it to move out of the line of attack — and exposing a less valuable piece behind it, which can then be captured.
Tactics
Smothered mate
A smothered mate is a checkmate delivered by a knight, in which the mated king is completely surrounded — or "smothered" — by its own pieces and has no escape square.
Tactics

Tactical initiative in chess is the ability to generate a continuous sequence of concrete, calculable threats that force the opponent into a passive or reactive stance, leaving them little time to pursue their own plans.
