Let’s dive in and expand your chess vocabulary!
1. General Chess Terms
A. Check
When a king is under direct attack by an opponent’s piece, the player must get out of check by moving the king, blocking the attack, or capturing the threatening piece.
Example:
“White plays Qh5+, putting the black king in check.“
B. Checkmate
A position where the king is in check and has no legal moves to escape. This ends the game.
Example:
“Black resigned after Qg7#, delivering checkmate.”
C. Stalemate
A draw where the player whose turn it is has no legal moves but is not in check.
Example:
“White thought they were winning but accidentally stalemated the black king.”
D. Castling
A special move where the king moves two squares toward a rook, and the rook jumps to the other side of the king. There are two types:
Kingside castling (0-0) – King moves to g1/g8, rook to f1/f8.
Queenside castling (0-0-0) – King moves to c1/c8, rook to d1/d8.
Example:
“White castled early to secure the king and connect the rooks.”
E. En Passant
A special pawn capture that occurs when a pawn moves two squares forward from its starting position and lands beside an opponent’s pawn. The opponent can capture it as if it had moved only one square.
Example:
“Black played exd6 en passant, capturing White’s pawn.”
F. Promotion
When a pawn reaches the opposite side of the board, it can be promoted to a queen, rook, bishop, or knight (usually a queen).
Example:
“White pushed the pawn to e8 and promoted to a queen, winning the game.”
2. Opening Terms
A. Development
Moving pieces from their starting positions to more active squares, usually in the opening phase.
Example:
“Black’s development was slow, allowing White to control the center.”
B. Center Control
The fight for dominance over the central squares (d4, d5, e4, e5). Controlling the center allows better piece mobility.
Example:
“White played e4 and d4 to take control of the center early.”
C. Gambit
A sacrifice of material (usually a pawn) in the opening to gain a positional advantage.
Example:
“The Queen’s Gambit (1.d4 d5 2.c4) offers a pawn to control the center.”
D. Tempo
A unit of time in chess. Losing a tempo means wasting a move, while gaining one means forcing the opponent to lose time.
Example:
“Black’s knight moved twice in the opening, losing a tempo.”
3. Middlegame Terms
A. Fork
A tactic where a single piece attacks two or more enemy pieces at once.
Example:
“The knight jumped to f7, forking the king and rook.”
B. Pin
A tactic where a piece is stuck because moving it would expose a more valuable piece behind it.
Absolute pin – Pinned against the king (illegal to move).
Relative pin – Pinned against a queen or other valuable piece.
Example:
“Black’s bishop on b4 pins the knight to the king.”
C. Skewer
Like a pin, but the more valuable piece is in front and must move, exposing the piece behind it.
Example:
“White’s rook on e1 skewers the king and queen, winning material.”
D. Discovered Attack
When a piece moves, uncovering an attack from another piece behind it.
Example:
“After Nf6+, the bishop on g5 discovered an attack on the queen.”
E. Zugzwang
A situation where any move a player makes worsens their position. Common in endgames.
Example:
“Black was in zugzwang and had to weaken their pawn structure.”
4. Endgame Terms
A. Opposition
A key concept in king-and-pawn endgames where the kings face each other with an odd number of squares between them. The player not to move is said to have the opposition.
Example:
“White used opposition to promote the pawn.”
B. Passed Pawn
A pawn with no opposing pawns blocking its path to promotion.
Example:
“Black’s passed pawn on c6 was a major threat.”
C. Lucena Position
A winning technique in rook endgames where the defending side promotes a pawn with rook support.
Example:
“White set up the Lucena Position to secure the win.”
D. Philidor Defense
A defensive rook endgame technique to hold a draw by keeping the rook on the 6th rank.
Example:
“Black used the Philidor Defense to save the game.”
5. Chess Notation Terms
A. Algebraic Notation
The standard system for recording moves using letters (a-h) and numbers (1-8).
Example:
“e4” means pawn moves to e4.
“Nf3” means knight moves to f3.
B. Check (+) and Checkmate (#)
“Qh5+” – Queen gives check.
“Qh7#” – Queen delivers checkmate.
C. Capture (x)
“Bxf7” – Bishop captures on f7.
D. Castling (0-0 or 0-0-0)
“0-0” – Kingside castling.
“0-0-0” – Queenside castling.
6. Strategic Terms
A. Open File
A file (vertical column) with no pawns, ideal for rooks.
Example:
“White doubled rooks on the open d-file for maximum pressure.”
B. Outpost
A strong square (usually protected by a pawn) where a knight or bishop can’t be easily dislodged.
Example:
“The knight on d5 was a powerful outpost.”
C. Weakness
A pawn or square that is difficult to defend and can be targeted.
Example:
“Black’s isolated pawn on d6 became a weakness.”
D. Zwischenzug (In-Between Move)
An unexpected move inserted before a seemingly forced sequence.
Example:
“Instead of recapturing, White played a zwischenzug with Qa4+.”
