History of Chess
Chess: A 1,500-Year-Old Intellectual Art
Spanning over 1,500 years, chess has evolved from its military-inspired origins into a global game that transcends civilizations. What began as a pastime has grown into a competitive arena, where the battle on the board is also a collision of human intelligence and culture.
The Inspiration of Chaturanga: It All Began in India
More than 1,500 years ago, the predecessor of chess, Chaturanga, was born in ancient India. This was not just a game of board strategy—it was a story of power and tactics.
In Sanskrit, "Chaturanga" means "four divisions," representing the four key units of the ancient Indian army: war elephants, cavalry, chariots, and infantry. Through the simulation of battles on the chessboard, players could experience the art of strategy and confrontation, while also embracing the ideal of replacing conflict with wisdom. According to legend, the game was originally designed for a war-weary prince, allowing him to relive the dynamics of war in silence, helping the king understand the cost of conflict and the value of wisdom.
However, at the time, the game was not entirely strategy-based—the inclusion of dice rolls introduced an element of luck. This seemingly simple addition reflected an intriguing aspect of ancient Indian culture, where chance and destiny were deeply intertwined.

Persian Shatranj: From War to a Battle of Wits
Between the 6th and 7th centuries, along the Silk Road, Chaturanga spread to Persia, where it underwent a transformation. Like a traveler shaped by different cultures, the game gained new life through adaptation.
The Persians renamed it Shatranj and refined the rules, removing dice rolls and enhancing strategic depth. More importantly, Persian culture infused the chessboard and pieces with profound philosophical meanings:
The board was seen as a miniature universe.
Each piece symbolized different roles in society—the vizier, chariots, and soldiers each had their duties in an intellectual war.
Shatranj became a favorite pastime of Persian nobility and spread among scholars, transforming into a symbol of intelligence and culture. From this point onward, chess began to transcend its role as a mere game, carrying deeper cultural and philosophical significance.

Medieval Europe’s Transformation: The Age of Knights and Queens
By the 10th century, Shatranj entered Europe through Arab cultural exchanges. The game absorbed the essence of medieval European traditions, evolving into a symbol of knighthood and feudal order, rather than just an Eastern-style war simulation.
During this cultural adaptation, the roles of the pieces changed significantly:
- The Persian vizier (Visier) became the Queen, which, over time, evolved into the most powerful piece on the board—a reflection of the rising status of women during the Renaissance.
- The Persian war chariot (Rukh) transformed into the Rook (Castle), symbolizing medieval Europe's focus on fortifications and land defense.
- The introduction of the Bishop represented the rise of religious power, making it a crucial force in the game.
Chess became a social language among European nobles and intellectuals. Many famous medieval literary works, such as "The Song of Roland" and "The Legend of King Arthur," featured chess as a symbol of wisdom and strategy. For the aristocracy, playing chess was not just entertainment—it was a way to demonstrate intelligence and political acumen.
The Birth of Modern Chess: Standardized Rules and Theoretical Foundations
By the 15th century, chess transitioned from medieval romanticism to a more competitive and modernized era. Italy, Spain, and France became the core drivers of this transformation, ultimately shaping the rules of modern chess.
The Rise of the Queen
One of the most significant changes in late 15th-century chess was the enhancement of the Queen’s power. From a limited-moving piece, the Queen became the most dominant force on the board. This sped up gameplay dramatically and introduced new strategic dynamics.
The Italian Golden Age
During the 16th century, Italy became the intellectual hub of chess theory. Many opening strategies and tactical principles originated here, such as those found in Luigi Lucena’s book The Art of Chess. His work systematized chess knowledge, providing future players with a map of strategic wisdom.
Global Standardization of Rules
By the 19th century, with the rise of the Industrial Revolution and the expansion of cultural exchanges, chess underwent global rule standardization. In 1849, Staunton-style chess pieces were introduced, becoming the universally recognized standard for modern chess competitions.
Chess Reaches Its Peak: From World Champions to Artificial Intelligence
From the mid-19th century to the present, chess has evolved from a traditional game into a competitive global sport. Several landmark events have shaped its journey:
- 1851 London Tournament – The first international chess competition marked the beginning of chess as a professional sport.
-
1886 – The First World Chess Champion – Wilhelm Steinitz became the first official world chess champion, paving the way for future generations of chess legends.

- The Era of Artificial Intelligence – In 1997, Deep Blue defeated Kasparov, marking the beginning of AI’s impact on chess. In 2017, AlphaZero revolutionized chess strategy. Today, AI-driven platforms allow chess enthusiasts worldwide to participate in the game like never before.
Chess: A Civilization’s Dialogue Through Time
From its origins as a military simulation in ancient India to a globally embraced intellectual pursuit, chess has endured over 1,500 years of evolution. On a simple 64-square board, chess tells the story of human civilization, reflecting strategic thought, cultural exchange, and historical transformation.
The black-and-white battle on the board is no longer just a game—it is a living epic of civilization. Chess has transcended language, borders, and time, uniting different cultures in a shared intellectual challenge. It provides a common platform for people from diverse backgrounds, allowing them to express their wisdom, creativity, and passion in a universal language of strategy.
Basic Rules of Chess
In chess, the initial setup is as shown in the diagram. Additionally, please note:
1.Regardless of whether you are playing as White or Black, the lower-left corner should always be a dark square.
2.If the board has coordinates, the white rook should be placed on a1.
3.The white queen starts on a light square, while the black queen starts on a dark square.
4.White always moves first at the beginning of the game.
Pieces's Point Value
How the Pieces Move
The King
The king can move one square in any direction. The black dots indicate the possible moves of the king.
The Queen
The queen can move multiple squares in any direction. The black dots indicate the possible moves of the queen.
The Bishop
The bishop can move multiple squares along the diagonals. The black dots indicate the possible moves of the bishop.
The Knight
The knight moves in an "L" shape and is the only piece that can jump over other pieces. The black dots indicate the possible moves of the knight.
The Rook
The rook can move multiple squares vertically or horizontally. The black dots indicate the possible moves of the rook.
The Pawn
Pawns can move one or two squares forward, but they can only move two squares on their first move. After that, they can only move one square forward at a time. Pawns are also the only pieces whose capturing method differs from their movement. They can only capture an opponent's piece one square diagonally in front of them. Lastly, pawns are the only pieces that cannot move backward.
Special Moves
Pawn Promotion
Pawns are the only piece in chess that can promote. Pawn promotion occurs when the Pawn reaches the end rank of opposite side of the board (1st rank of black, 8th rank of white).
En Passant
En Passant is a special Pawn move. If a Pawn steps forward two squares and landing adjacent to an opponent's Pawn, the opponent's Pawn may capture your Passant and move one square forward. The En Passant capture is optional, because it only take place after a Pawn moves two squares and only on the move immediately following.
Castling
Castling is a special move to make the King safer. In one turn, the Castling is done by having the king move two squares in the direction of the Rook, and then the Rook crosses over the king and is placed on the square adjacent to the king.[Ref.Figure1& Figure2]
Rules of Castling:
1.The King cannot castle if either the King or the Rook involved have already moved in that round.
2.There can be no pieces between the King and the Rook.
3.The King cannot castle while in check. [Ref.Figure3]
4.The King cannot castle into or through checkmate.[Ref.Figure4]
5.The King can never "un-castle" after castiling already.
6.Moving with single hand, King moves firstly and Rook moves secondly.

Size Standards
Chess Board Dimensions Basics and Guidelines
The geometric structure of a chessboard is relatively simple, but the relationship between the board size, square size, and piece dimensions is more complex than it seems. Below, we introduce the basic dimensions and common standards for chess sets, along with key factors to consider when selecting a board and pieces.
1.Chess board basics
A chessboard consists of an 8x8 grid, comprising 64 alternating light and dark squares, with 32 light-colored squares and 32 dark-colored squares. Each square is of equal size, and all four sides of the board should be of equal length.

2.Chess board & Piece standards
According to the World Chess Federation (FIDE) standards, the square size for tournament chessboards should be between 5 cm to 6 cm (2 to 2.36 inches).
The recommended heights for tournament chess pieces are as follows:
- King: 9.5 cm (3.75 inches)
- Queen: 8.5 cm (3.34 inches)
- Bishop: 7 cm (2.75 inches)
- Knight: 6 cm (2.36 inches)
- Rook: 5.5 cm (2.16 inches)
- Pawn: 5 cm (1.96 inches)
The base diameter of the pieces should be 40%-50% of their height. These dimensions may vary by up to 10% from the recommended values, but the order must remain consistent (e.g., the king must always be taller than the queen, etc.).
For FIDE tournaments, it is recommended to use Staunton-style chess pieces, which should be clearly distinguishable from each other in shape.
3. Ratio Between Chessboard & Chess Pieces
The recommended ratio between the king's base diameter and the square size is 75%-80%. This proportion ensures proper spacing between pieces on the board.
Here is an example of a standard chessboard and piece size following the 75%-80% principle:
- King height: 3.75 inches (9.5 cm)
- King base diameter: 1.75 inches (4.45 cm) (47% of the king's height)
- Square size: 2.25 inches (5.7 cm)
- King base-to-square ratio: 77%
This setup ensures proper spacing between the board and the pieces, making it ideal for all types of chess games, including tournaments, rapid games, analysis, and casual play.
Ignoring the 75%-80% rule can lead to an imbalanced proportion.If the king's base-to-square ratio is too high, the board may appear too crowded.Example: A 1.875-inch square size with a 3.75-inch king (base diameter 1.75 inches) results in a 93% ratio.
As seen in the example, the king nearly fills the entire square, making the board visually cluttered and increasing the risk of knocking over pieces.If the ratio is too low (below 75%), the board may feel too spacious.Example: A 3.25-inch king with a 1.31-inch base diameter, placed on a 2.25-inch square size, results in a 58% ratio.
Here, the king occupies less than half the square, making the board appear too empty, and the pieces feel too far apart.
4. Chess Piece Spacing Test
A simple test to check if a board has enough space is the "Four Pawns Test."
Most tournament chess sets should allow four pawns to fit comfortably within a single square. If you are using a standard chessboard and chess piece combination, this test should work.

When selecting a chessboard and piece combination, several rules, standards, size ranges, and proportions should be considered. The information above applies not only to competitive tournaments but also serves as a useful reference for casual chess games.
The goal of choosing the right board and piece combination is simple: ensure a balanced and comfortable playing experience on a properly sized chessboard.
