The player with White pieces starts
first, chooses his/her chess piece and moves it according to rules for this type of the
piece (see chess pieces). After each move, the players take
Capturing Opponent's Chess Pieces
None of the chess pieces may move to a square occupied
by another chess piece of the same color. However, a piece may move onto a square occupied
by an opponent's piece. When this occurs, the opponent's piece is 'captured' and is
permanently removed from the chessboard. The attacking piece is moved to the square of the
former captured piece.
|If it's White's turn to move, the
following captures are possible in the diagram on the left:
If it's Black's turn to move, the following captures are possible in the diagram on the left:
|The Pawn can capture an opponent's pawn
'in passing' or 'en-passant' (since the French expression is commonly used here).
For the en-passant rule to apply, the following two conditions have to be met:
In the diagram on the left, en-passant move applies after White pawn moves from a2 to a4. The Black pawn can capture the White Pawn on the a3 square on the very next move only.
|Once in a game each player can make a
special 'castling' move. During this 1 move, both the king and one of its rooks are moved.
Castling starts by moving the king 2 squares as indicated by arrows. At hessLab, if the
castling is legal, the corresponding rook move would occur automatically.
For castling to be legal, the following four conditions have to be met:
When a White pawn advances to the last 7-th "rank," or
horizontal row of squares, or when the Black pawn advances to its last 1-st rank, it is
promoted into its owner's choice of a knight, bishop, rook, or queen (it may not become a
king). The usual choice for promotion is a queen, the most powerful piece. It is legal for
a player to have several queens on the board at the same time. Occasionally, it is better
to promote to a knight (to fork two pieces or avoid stalemate--draw) or a bishop or rook
(to avoid stalemate-draw). At GameColony.com, when a pawn reaches the eighth rank, a window will
pop up asking the pawn's owner to choose which piece to promote to.
Check and Checkmate
|Check and Checkmate example:
White king above is under check
|The goal in chess is to capture (or checkmate) the
opponent's king. That is why all players have to protect their kings. If an opponent's
piece is threatening to capture the king, the king is said to be 'in check'. It is
illegal to move the king onto a square where it would be under attack (in check). If the
king is in check, the king's owner must do something to protect the king right away.|
To protect the king, the player may try the following three defenses:
If none of the the above 3 defenses work, the king is not just
'under check' -- such king is said to be checkmated. With checkmate, the game is over. The
side whose king is checkmated
If none of the the above 3 defenses work, the king is not just 'under check' -- such king is said to be checkmated. With checkmate, the game is over. The side whose king is checkmated
& Other Draws
The players can elect to use time control to limit the
time spent on a game. At GameColony.com, time control can be adjusted via 'Options' button. If
there is no checkmate on the board, the player whose time expires first loses, unless
there is a draw via stalemate, insufficient mating material, etc.
Rather than wait for a checkmate or a loss due to
expiration of time, the player may choose to resign the game. For this purpose, at
GameColony.com 'Resign' button can be selected.
