Once connected to the physical Millennium chess board LEDs will light if the physical board is not the same as the position shown in the database view, game notation. Adjust physical pieces accordingly until the physical position matches that shown on screen. Once in sync HIARCS Chess Explorer will try to maintain the physical board and displayed position in sync with each other.
