During the competition a special chessboard is used, equipped with electronic sensors that capture the movement of figures. From the board information about the moves is sent to the computer of the judge of the competition, then to the server of the Federation. From the server via specially crafted gateways the information comes to the website of World Chess, transforming back into a board with figures.
In the initial tests, the difference between the move of the player and the display in the broadcast was 30–60 seconds. After debugging the difference was reduced to 3–5 seconds
