| Ashtāpada board on which chaturanga was played.
}}

The earliest known ancestor of the chessboard is the [[Ashtapada|Ashtāpada]] board. Among other games, it was used to play [[chaturanga]], a historical precursor to chess, beginning around the 6th century in [[India]]. The board uses a single color for all squares and is divided into eight columns by eight rows, with marked squares called ''castles'' in the corners of each quadrant. Unlike in Ashtāpada, castles serve no function in chaturanga.<ref>{{Cite book|url=https://books.google.com/books?id=IyFHvy-SCIYC&q=ashtapada&pg=PA46|title=Sports and Games of Medieval Cultures|last=Wilkins|first=Sally E.

The chessboard acquired its modern chequered pattern in the 10th century with the arrival of chess in Europe.<ref>Yalom 2004, p. 17.</ref> This pattern was based on that of the then-5×5 [[draughts]] board.<ref>{{Cite web|url=http://www.checkershistory.com/|title=The Checkered History of Checkers|access-date=July 5, 2018}}</ref> As a result of this change, each diagonal was now highlighted by a continuous sequence of same-coloured squares, which later facilitated the introduction of the modern [[Bishop (chess)|bishop]] and [[Queen (chess)|queen]] movements in the 15th century.<ref>Hooper & Whyld 1992, p. 48.</ref>

The [[Libro de los juegos]] (1283) contains a description of the chessboard, describing eight rows and columns as the ideal number, deeming the practice of chess on the 10×10 board too tiresome and on the 6×6 board too quick.<ref>Yalom 2004, p. 62.</ref> In the 13th century, some players began using the convention that the first square of the far right column should be light-coloured; this convention was endorsed by [[Pedro Damiano]] at the end of the 15th century.<ref>Hooper & Whyld 1992, p. 47.</ref>

In contemporary chess, a ''digital board'' is a chess board connected to a computer that is capable of transmitting the moves to the computer itself: the information about the moves can be used to play a game against a [[chess engine]], or simply to record the moves sequence of a game in automatic.

A digital board uses sensors to detect the pieces position and each piece move can be recorded.

In 1998 the [[33rd Chess Olympiad]] was held in [[Elista]]: the games were digitally broadcast over the internet thanks the introduction of digital chess boards developed by [[Digital Game Technology]]: 328 boards were used for the event.<ref>{{Cite web|url=https://digitalgametechnology.com/about-us| title=DGT history }}</ref>

In 2003, the [[List of World Chess Championships|ex-world champion]] [[Garry Kasparov]] faced the [[chess engine]] [[X3D Fritz]] in a series of four matches in a [[Virtual reality|virtual environment]], where the computer-generated board hovered in the air in front of Kasparov, who used special glasses. This was the first man–machine game of chess performed in a completely simulated environment.<ref>{{Cite web|url=http://www.chessgames.com/perl/chessgame?gid=1269891|title=Kasparov versus X3D Fritz}}</ref>
