"The membership fee is extremely reasonable, considering that it gives you a year's unlimited playing time... plus access to lectures, interviews and coverage of major events." — Sarah Hurst, Chess on the Web
The forward command is used when a player is in the "examine" mode. It
shows the position in the game the specified number of half-moves ahead. If
no number is given, the default is '1'. Also, just pressing the Enter key
is equivalant to "forward 1". "forward 999" will get you to the end of the
game.
