Strategy chess terms
Every strategy term, defined and illustrated.
- Strategy
Active piece
An active piece in chess is a piece placed on a square where it controls as many squares as possible, participates in threats, and contributes fully to the game — whether attacking or defending.
- Strategy
Bad bishop
A bad bishop is a bishop whose mobility is severely restricted because its own pawns are fixed on squares of the same color, trapping it behind its own pawn structure.
- Strategy
Bishop pair
The bishop pair refers to owning both bishops — the light squared and the dark squared — while the opponent has lost one or both of theirs.
- Strategy
Blockade
A blockade is a strategic technique that consists of placing a piece directly in front of an opponent’s pawn in order to immobilize it and halt its advance.
- Strategy
Candidate move
A candidate move is any move a player identifies as worth analyzing before making a final decision.
- Strategy
Center control
Center control refers to the strategic command of the central squares of the chessboard — primarily e4, d4, e5, and d5 — through pawns, pieces, or a combination of both.
- Strategy
Centralization
Centralization in chess refers to the strategic principle of placing pieces on or near the center of the board — squares e4, d4, e5, d5 and their neighbors — in order to maximize their range and overall influence on the game.
- Strategy
Compensation
Compensation in chess refers to the set of non material advantages — initiative, piece activity, centre control, pawn structure — that offset a deficit in material or another type of imbalance.
- Strategy
Converting an advantage
Converting an advantage in chess means transforming an existing edge — whether material, positional, or dynamic — into a concrete result: a win by checkmate or by the opponent’s resignation.
- Strategy
Domination
Domination in chess refers to a situation where an opponent’s piece is unable to move freely — or is effectively trapped — without being formally pinned or directly captured: it is simply confined to a zone fully controlled by your pieces.
- Strategy
Dynamic play
Dynamic play in chess refers to a style of play centered on piece activity, initiative, and the creation of concrete threats, rather than the patient accumulation of long term structural advantages.
- Strategy
Fortress
A fortress is a defensive technique in which the materially inferior side builds an impregnable position, forcing the opponent to accept a draw because they cannot break through.
- Strategy
Good bishop
A good bishop is a bishop whose diagonals are not obstructed by its own pawns, allowing it to move freely and exert maximum influence across the board.
- Strategy
Initiative
In chess, the initiative refers to a player’s ability to set the pace of the game by creating threats that force the opponent to react, rather than pursue their own plans.
- Strategy
Maneuver
A maneuver in chess is a sequence of coordinated moves — typically quiet ones — aimed at improving the position of one or more pieces without creating an immediate direct threat.
- Strategy
Outpost
An outpost is a stable square — typically in the center or enemy territory — where a piece, most often a knight, can be permanently stationed without being driven away by an opponent’s pawn.
- Strategy
Overprotection
Overprotection is a strategic technique that consists of defending a key square or piece with more defenders than strictly necessary to hold it against the opponent’s attacks.
- Strategy
Passive piece
A passive piece is a piece that occupies a square where it has limited mobility, controls few important squares, and contributes little to its side’s active play.
- Strategy
Piece activity
Piece activity refers to a piece’s ability to influence as many squares as possible, participate meaningfully in the game, and generate concrete threats on the board.
- Strategy
Piece coordination
Piece coordination refers to the ability of a player’s pieces to work together harmoniously, supporting one another and combining their strengths toward a common objective.
- Strategy
Plan
A plan in chess is a coherent sequence of connected ideas that a player decides to pursue in order to improve their position or gain an advantage over their opponent.
- Strategy
Play on both flanks
Play on both flanks is a strategic concept that involves creating threats on both the kingside and the queenside, forcing the opponent to spread their defensive resources across the entire board.
- Strategy
Position evaluation
Position evaluation is the process by which a chess player analyses the board to determine which side holds an advantage, and what kind of advantage it is.
- Strategy
Positional advantage
A positional advantage in chess refers to a situation where one player holds a structural or qualitative superiority on the board, without necessarily having more material than the opponent.
- Strategy
Positional play
Positional play is a strategic approach to chess that focuses on gradually improving piece placement, creating long term weaknesses in the opponent’s position, and accumulating small advantages rather than seeking an immediate tactical conclusion.
- Strategy
Principle of two weaknesses
The principle of two weaknesses is a strategic concept in chess stating that one weakness in a position is often defensible, but two weaknesses on opposite sides of the board typically cannot both be held at the same time.
- Strategy
Prophylaxis
Prophylaxis in chess is the art of anticipating and neutralizing the opponent’s plans before they become dangerous.
- Strategy
Restriction
Restriction in chess is a strategic concept that involves limiting the mobility and activity of the opponent’s pieces — without necessarily capturing them — in order to gradually suffocate their position.
- Strategy
Simplification
Simplification is a strategic operation that consists of reducing the number of pieces on the board, typically through exchanges, in order to consolidate an existing advantage or neutralize the opponent’s counterplay.
- Strategy
Space advantage
A space advantage in chess refers to the situation where one side controls more squares on the board than the opponent, typically through advanced pawns that restrict the mobility of the enemy pieces.
- Strategy
Strategic exchange
A strategic exchange in chess refers to the deliberate trading of a piece for an opponent’s piece of nominally equal (or even slightly higher) value, with the goal of gaining a lasting positional advantage rather than an immediate material benefit.
- Strategy
Strong square
A strong square is a square that the opponent’s pawns can no longer attack, allowing a piece to settle there permanently without risk of being driven away by a pawn.
- Strategy
Weak square
A weak square in chess is a square that can no longer be defended by a pawn of the side that owns it, allowing the opponent to occupy it with a piece that cannot be driven away.
- Strategy
Wing expansion
Wing expansion is a strategic plan that involves advancing pawns on one side of the board — the kingside or the queenside — in order to gain space, open files, and generate concrete threats against the opponent’s position.
