DEMONSTRATION BOARD

demo board

A large chessboard mounted vertically, showing the position of a chess game, used either for a lecture or in a tournament. There are flat representative pieces and attendants move these pieces shortly after the moves are actually played. This allows spectators to see clearly what is happening on the actual playing board. Some demonstration boards also have clocks showing the two thinking times used.

There are now electronic wall-board and TV monitors that react instantly via a connection with the actual board and make it easy for an audience to be completely involved in the action. The first demonstration board, 4 ft (1.2m) square, was designed by Lowenthal in 1857 and used by him to illustrate his lectures.
