+
+MAKING MOVES IN A CHESS MATCH
+
+ Once you have arranged for a match, you begin playing and moving the pieces
+around. There are two ways to make chess moves during a match. Many user's
+have a graphics interface. In this case, the user moves the piece on the
+graphics board using the computer mouse, and the interface software translates
+this move into chess notation and sends the move to the server for processing.
+Read the interfaces information file for a few details about graphics
+interfaces.
+
+ If you don't have a graphics interface, you will need to enter your moves
+using a keyboard. In order to do this, you have to know what kind of chess
+notation the server uses. Chess players use one of two different notational
+systems: descriptive and algebraic. The server understands algebraic. (The
+server also understands a computer version of chess notation; see below.)
+
+ In algebraic notation, each square has a unique label. Each rank is labeled
+1 to 8, with the rank on White's side being 1. Each file is labeled a to h,
+with the file on White's left side being a. So each square has a file label
+and a rank label, with the file listed first. In algebraic notation, each
+chess piece has its own symbol: k = king; q = queen; b = bishop; n = knight; r
+= rook; p = pawn (though the "p" is not really used).
+
+ Here is a sample of a match position as displayed in the default style 1.
+For this example, White is at the bottom of the board and Black is at the top.
+Symbols are in capital letters; the * means the piece is Black's.
+
+ ---------------------------------
+ 8 | | *R| | | *R| | *K| |
+ |---+---+---+---+---+---+---+---|
+ 7 | *P| | | *B| *P| *P| *B| *P|
+ |---+---+---+---+---+---+---+---|
+ 6 | | | | | | *N| *P| |
+ |---+---+---+---+---+---+---+---|
+ 5 | *Q| | | *P| | | B | |
+ |---+---+---+---+---+---+---+---|
+ 4 | | | | | | P | | |
+ |---+---+---+---+---+---+---+---|
+ 3 | | | N | B | P | | | |
+ |---+---+---+---+---+---+---+---|
+ 2 | P | P | | | Q | | P | P |
+ |---+---+---+---+---+---+---+---|
+ 1 | | | R | | | R | K | |
+ ---------------------------------
+ a b c d e f g h
+
+ Black's king (*K) is on the g8 square; White's king (K) is on the g1
+square, and so on. It is Black's move. Suppose Black wants to place the
+knight (*N) on the e4 square. The move to enter in algebraic would be Ne4.
+Moving pawns is simpler; you don't use the "p" for the piece and just give
+the square the pawn is moving to. Suppose Black decides to move the pawn
+(*P) on the h7 square to the h6 square. The move to enter would be h6. In
+many board positions, more than one rook, knight or pawn could move to the
+same square. In this case, you have to indicate which of the two pieces you
+want to move. For example, suppose Black has knights on c2 and e2; they could
+both move to d4. To move the knight on c2 to d4 you could type Ncd4, where
+the "c" serves to tell the server which knight to move.
+
+ In algebraic notation, captures are usually denoted by "x". Suppose Black
+wants to capture White's b2 pawn (P) with the rook (R) on b8. Black would
+enter the move Rxb2. However, the server would also understand the simple Rb2
+and know that a capture is implied. So, for this server, you can enter the
+square the piece will capture on. To make a castle move, use O-O to castle on
+the king's side and O-O-O to castle on the queen's side.
+
+ Many computers want very explicit instructions on how to move pieces.
+This "computer" notation has the following format: square_from-square_to
+
+ For example, in the above board position, moving the Black rook from b8 to
+b2 would be entered b8-b2. Piece symbols are never used; only the squares.
+The server understands computer notation as well.
+
+ In short, to move a piece during a chess match, enter the move. Each time
+you and your opponent make a move, the server updates the board position and
+sends the new position to both you and your opponent. It's that simple!
