Dragonfly notation
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 'd23'.
    You must comply with the required format, in this case 'd2-d3'.
  • 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.
  • Castling: simply move the King two squares: 'd1-b1'. It is not allowed to castle with a previously dropped rook.
  • For a 'piece drop', specify the piece and the square you want to enter it on, separated by a hyphen. e.g. 'B-c5'
  • As for promotion: add the letter of the piece you want to promote to after the move, as in 'd6-d7 R' (Rook, Bishop, kNight). Be sure to put a space between the move and the letter!
    Promotion follows automatically. Remember you may only promote to a piece the opponent has 'in hand'.
  • 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 Dragonfly 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.
  • In a promotion, you can now simply click the piece you want to promote to from your opponent's 'hand'.
  • 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.
