+	Chess is a two-player strategy board game. <application>glChess</application> is a 2D/3D chess game, where games
+	can be played between a combination of human and computer players. glChess detects known third party chess engines
+	for computer players. The game was originally developed by Robert Ancell, now the game is included in gnome-games.
+  </para>
+
+  <para>
+	<application>glChess</application> is written in Python and uses GTK+ and Cairo to render the chess board. 3D support is 
+	optionally available using OpenGl,
+	using the Python OpenGL and GtkGLExt libraries. As with most modern 3D programs hardware acceleration is recommended but it should
+	run OK in software. glChess is bundled with GNU Chess as the default chess AI. glChess can be played in network mode against 
+	other players on the Internet.
+  </para>
+  <para>
+	Chess is played on a square chessboard, consisting of 64 squares of alternating color. Each player begins the game with sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. One player controls the white pieces and the other player controls the black pieces; the player that controls white is the first to move. The players take turns moving pieces; certain moves involve a "capturing" of an opponent's piece, removing it from the chessboard. The object of the game is to checkmate the opponent's king. This occurs when the king is under immediate attack (in check) and there is no way to remove it from attack on the next move. Theoreticians have developed extensive chess strategies and tactics since the game's inception.
+</para>
+<para>
+The current form of the game emerged in South Europe in the second half of the 15th century after evolving from similar, much older games of Asian origin. Chess is one of the world's most popular board games. The tradition of competitive chess began in the 16th century. The first official World Chess Champion, Wilhelm Steinitz, claimed his title in 1886; his modern equivalent, Vladimir Kramnik, is the 14th Champion in the lineage. There are also biennial world team events called Chess Olympiads. Since the 20th century, two international organizations, the World Chess Federation and the International Correspondence Chess Federation have organized and overseen the top chess competitions and international titles.
+</para>
+<para>
+One of the goals of early computer scientists was to create a chess-playing machine, and today's chess is deeply influenced by the overwhelming abilities of current chess programs. In 1997, a match between Garry Kasparov, then World Champion, and IBM's Deep Blue chess program proved that computers are able to beat even the strongest human players.

+  <para>
+Chess is played on a square board of eight rows (called ranks and denoted with numbers 1 to 8) and eight columns (called files and denoted with letters a to h) of squares. The colors of the sixty-four squares alternate between light and dark, and are referred to as "light squares" and "dark squares". The chessboard is placed so that each player has a white square in the near right hand corner, and the pieces are set out as shown in the diagram, with each queen on a square that matches its color.
+</para><para>
+Each player begins the game with sixteen pieces: each player's pieces comprise one king, one queen, two rooks, two bishops, two knights and eight pawns. One player, referred to as White, controls the white pieces and the other player, Black, controls the black pieces; White is always the first player to move. The colors are chosen either by a friendly agreement, by a game of chance or by a tournament director. The players alternate moving one piece at a time (with the exception of castling, when two pieces are moved at the same time). Pieces are moved to either an unoccupied square, or one occupied by an opponent's piece, capturing it and removing it from play. With one exception (en passant), all pieces capture opponent's pieces by moving to the square that the opponent's piece occupies.
+</para>
+ <sect3 id="rules-piece-king">
+  <title>King</title>
+<para>When a king is under direct attack by one (or possibly two) of the opponent's pieces, the player is said to be in check. When in check, only moves that remove the king from attack are permitted. The player must not make any move that would place his king in check. The object of the game is to checkmate the opponent; this occurs when the opponent's king is in check, and there are no moves that remove the king from attack.
+
+</para><para>
+    The king can move only one square horizontally, vertically, or diagonally. Once in the game, each king is allowed to make a special double move, to castle. Castling consists of moving the king two squares towards a rook, then moving the rook onto the square over which the king crossed. Castling is only permissible if all of the following conditions hold:

+  <title>Bishop</title>
+<para>
+    The bishop moves any number of vacant squares in any direction diagonally. Note that a bishop never changes square color, therefore players speak about "light-squared" or "dark-squared" bishops.

+    The queen can move any number of vacant squares diagonally, horizontally, or vertically.

+ <sect3 id="rules-piece-knight">
+  <title>Knight</title>
+<para>
+    The knight can jump over occupied squares and moves two spaces horizontally and one space vertically or vice versa, making an "L" shape. A knight in the middle of the board has eight squares to which it can move. Note that every time a knight moves, it changes square color.
+
+</para>
+</sect3>
+ <sect3 id="rules-piece-pawns">
+  <title>Pawns</title>
+<para>
+
+    Pawns have the most complex rules of movement: A pawn can move forward one square, if that square is unoccupied. If it has not moved yet, the pawn has the option of moving two squares forward, if both squares in front of the pawn are unoccupied. A pawn cannot move backward. When such an initial two square advance is made that puts that pawn horizontally adjacent to an opponent's pawn, the opponent's pawn can capture that pawn "en passant" as if it moved forward only one square rather than two, but only on the immediately subsequent move. Pawns are the only pieces that capture differently than they move. They can capture an enemy piece on either of the two spaces adjacent to the space in front of them (i.e., the two squares diagonally in front of them), but cannot move to these spaces if they are vacant. If a pawn advances all the way to its eighth rank, it is then promoted (converted) to a queen, rook, bishop, or knight of the same color. In practice, the pawn is almost always promoted to a queen.
+</para>
+</sect3>
+
+<sect3 id="rules-movement-others">
+<title>Remaining movement rules</title>
+<para>
+With the exception of the knight, pieces cannot jump over each other. One's own pieces ("friendly pieces") cannot be passed if they are in the line of movement, and a friendly piece can never replace another friendly piece. Enemy pieces cannot be passed, but they can be "captured". When a piece is captured (or taken), the attacking piece replaces the enemy piece on its square (en passant being the only exception). The captured piece is thus removed from the game and may not be returned to play for the remainder of the game. The king cannot be captured, only put in check. If a player is unable to get the king out of check, checkmate results, with the loss of the game.

+</para><para>
+Chess games do not have to end in checkmate — either player may resign if the situation looks hopeless. Games also may end in a draw (tie). A draw can occur in several situations, including draw by agreement, stalemate, threefold repetition of a position, the fifty move rule, or a draw by impossibility of checkmate (usually because of insufficient material to checkmate).

+<title>Timed Games</title>
+<para>
+Games can be played with a time-limit by setting a move time when creating a new game. In timed games each
+player has a certain amount of time available for deciding which moves to make, and the time remaining 
+for each player decreases only when it is their turn to move.
+</para>

+
+<sect2 id="draw">
+<title>Game Draw</title>
+<para>
+A game that ends without victory for either player. Most drawn games are draws by agreement based upon the rules. The other ways that a game can end in a draw are stalemate, three-fold repetition, the fifty-move rule, and insufficient material. A position is said to be a draw (or a drawn position) if either player can, through correct play, eventually force the game into a position where the game must end in a draw, regardless of the moves made by the other player.

+
+
+<sect3 id="stalemate">
+<title>Stalemate</title>
+<para>
+A stalemate is a position in which the player whose turn it is to move has no legal move and his king is not in check. A stalemate results in an immediate draw.
+</para>
+</sect3>
+
+<sect3 id="threefold-repetition">
+<title>Threefold repetetion</title>
+<para>
+The game is drawn if the same position occurs three times with the same player to move, and with each player having the same set of legal moves each time (the latter includes the right to take en passant and the right to castle).
+</para>
+</sect3>
+
+
+<sect3 id="fifty-move-rule">
+<title>Fifty move rule</title>
+<para>
+The fifty move rule states that the game is drawn after fifty moves from each side without a pawn move or capture.
+</para>
+</sect3>
+
+<sect3 id="insuff-material">
+<title>Insufficient material</title>
+<para>
+An endgame scenario in which all pawns have been captured, and one side has only its king remaining while the other is down to just a king or a king plus one knight or one bishop. The position is a draw because it is impossible for the dominant side to deliver checkmate regardless of play. Situations where checkmate is possible only if the inferior side blunders are covered by the fifty-move rule.

+          PNG format is recommended for tile sets. The first, second, fifth
+          and sixth tiles should contain some transparency if you want the
+          background to show through. The third and fourth tiles should be
+          solid, with no transparency, even if you'll be using a full
+          window background image with your theme.
+        </para>
+      </tip>
+
+      <tip>
+        <title>TIP</title>
+        <para>
+          Tiles can be square or rectangular, and any size you like. Most
+          of the tile sets that come with &app; use square tiles measuring
+          50 pixels by 50 pixels.
+        </para>
+      </tip>
+
+      <para>
+        For a full window background image, there's a bit more work to do.
+        Let's say your tiles measure 50 by 50 pixels each. The game's display
+        measures 7 by 7 tiles, including the top row, so the ideal background
+        image for your tile set measures 350 by 350 pixels.
+      </para>
+
+      <tip>
+        <title>TIP</title>
+        <para>
+          &app; will automatically scale the background image if it doesn't
+          match the tile set. This means you can make "large" and "small"
+          versions of your theme, both using the same background image,
+          just by having a large and a small version of your tile set.
+        </para>
+      </tip>
+
+      <para>
+        So, you now have a tile set and perhaps a background image to
+        go with it. The next step is to put them in the right place.

+    diamonds to eat.  They are each a different color and serve
+    a different function. Only the pale purple diamond is guaranteed
+    to be around long enough for you to eat it (in fact, you have to
+    eat them to finish the level). The other diamonds are all bonuses,
+    but they only stick around for a short time. We'll leave it up to
+    you to discover just what the bonus each colour gives, but they
+    all affect either the score, the length of the worm, or both. Be careful

+     <title>GNOME Robots Objective</title>
+     <para>
+       The objective of GNOME Robots is quite simple. You are surrounded by a 
+       number of robots or other hostile adversaries. As you move about 
+       they will move directly towards you for every move that you make. 
+       Their goal is to kill you. Your goal is to kill all the robots on the 
+       board by taking advantage of their vulnerabilities. 
+     </para>
+   
+     <para>
+       Robots are destroyed when they collide with each other, or when they
+       collide with the debris of some previous collision. You die if a robot
+       ends up right next to you.
+     </para>
+
+     <para> In some of the game configurations (you can choose from
+       five different sets of rules), you can push the
+       junkheaps around to form barricades to protect you. Also, if you
+       are daring enough, you can Splat! the robots by pushing
+       junkheaps on top of them for an additional bonus.  </para>
+     <para>
+       You can also save yourself by teleporting yourself to a random location. 
+       Unfortunately, randomly teleporting means that
+       you might end up being right next to a robot, so they can kill you when
+       they make their move. Luckily, there are also
+       safe teleports which will place you out of immediate danger, but
+       there are only a limited supply of them. You can earn
+       more free teleports as you go along (how you gain them depends on the 
+       chosen game), but typically you get one for each robot that is
+       destroyed while you are 'waiting', up to a maximum of 10. If you don't
+       want to waste your saved-up safe teleports, you can choose to teleport
+       randomly if you think it's safe enough. 
+     </para>
+   
+     <para>
+       If you press the <guibutton>Wait</guibutton> button (see below) you will no longer be able to
+       move until either all of the robots (which still move towards you) are
+       gone, or you are killed. Doing this is risky, but may earn you extra 
+       safe teleports.
+     </para>
+   
+     <para> If you manage to reach the point where more than half of
+       the screen is occupied by robots, the number of robots will be
+       reset to the starting amount, allowing you to continue.

+          a score of zero and if you click on the wrong row, you
+          will be scored accordingly. (Say for example, you get

+     yahtzee. At the end of the game you will be given extra rolls to
