Abstract: A hand-held, portable apparatus for recording chess moves operable between a recording mode and at least one other mode is described. The apparatus is adapted to uniquely identifying a user and includes an interface for electronically entering into a memory a chess move made by the user. A mechanism is provided for the apparatus to switch between the at least one other mode and the recording mode upon a player making a first move in a new game. The recording mode further includes a security module so that only authorized features are accessible when the apparatus is in the recording mode. The apparatus includes a power module and a communication module for securely communicating chess moves to a central location. The moves are recorded in a universal language. The invention also concerns a chess game tournament management system, as well as a system for recording and publishing chess moves.
