Please read before you start your first game in the ArenA.

General
Entering a move is simple, but requires a fairly strict format. First and foremost:
  • Put the cursor on a square to get the coordinates and the piece, if present.
  • The applet does not accept shorthand notation such as 'e24'.
    You must comply with the required format, in this case 'e2-e4'.
  • However, the applet is basically a board and, provided the format is correct, will accept illegal moves just as a physical board would. There's an extended 'undo' function that allows you to take back any number of moves, provided the opponent cooperates by taking back his.
  • With the command menu you can undo your last move, end a game by accepting a loss, or negotiate a draw.

Specific
  • Specify the start- and endsquare, seperated by a hyphen (-), e.g. 'e3-g5'.
    You may add an 'x' to denote capture, e.g. 'e3-g5x', or replace the hyphen by an 'x', e.g. 'e3xg5', but neither is necessary.
    This also goes for en passant capture: 'e5-d6x' or 'e5xd6'.
  • CG-castling mode: enter O-O-O for 'C-castling' or O-O for 'G-castling'.
    Modified traditional castling mode: enter O-O-O for 'a-side' or O-O for 'h-side'.
    Note: the applet does NOT check for illegal moves, so you have to make sure the move is legal yourself.
  • As for promotion: add the letter of the piece you want to promote to after the move, as in 'd7-d8 Q' (Queen, Rook, Bishop, kNight). Be sure to put a space between the move and the letter! Promotion follows automatically.
  • If you find yourself in checkmate or otherwise in a lost position, please choose 'Resign' from the command menu as your 'move', to acknowledge and officially end the game.

New
  • The Chess960 applet is now 'clickable'. When moving a piece, click it first. Next click the square you want to move it.
    They will be marked and the corresponding move will appear in the "your Move" field.
  • Castling: simply move the King ONTO the castling rook. The move will follow the chosen 'castling mode'.
    Note again: the applet does NOT check for illegal moves, so you have to make sure the move is legal yourself.
  • In a promotion, you'll have to specify the piece you want the usual way - see 'Specific'.
  • To clear, click on the bottom-right button [>>>|] (go to end). Now you can start over.
  • The click method only works in the end position. When you're happy with the move, enter your password and click "Submit move" as usual.
