[edit] Notes on terminology

[edit] Pawns vs. Pieces

Many sources, when discussing chess, do not count pawns as pieces when discussing pieces. For simplicity of discussion, and in keeping with the usage of the term in the FIDE Handbook, I will consider pawns to be pieces throughout this discussion of the rules.

[edit] Other terminology issues

Also in keeping with the FIDE handbook, I will attempt to use the word colour rather than color, knight instead of horse, and rook rather than castle or tower or whatever they call it nowadays.

[edit] I. Basic Rules of Play

[edit] A.What Chess Is

1.Chess is a game played between two players who take turns moving pieces on a square board called a Chessboard^[1].

2.A player is said to have the move when one's opponent's move has been made^[2].

3.There are two sets of pieces, one light-coloured, referred to as white, and one dark-coloured, referred to as black. They consist of:

a. The kings: one white and one black ,

b. The queens: one white and one black ,

c. The rooks (also referred to as castles or towers, although castle has another meaning in Chess): two white and two black ,

d. The bishops: two white and two black ,

e. The knights (also referred to as horses): two white and two black ,

f. The pawns: eight white and eight black .

4. One player gets the white pieces, and the other gets the black pieces^[3].

5. The player with the white pieces moves first^[4].

6. The pieces start in the position shown on the right^[5]:

[edit] B. Movement of pieces

1. The eight columns of squares (from the initial position of the white pieces to the initial position of the black pieces, marked a-h on the starting position board) are referred to as files.

2. The eight rows of squares (the lines parallel to the initial line of white pawns and the initial line of black pawns, marked 1-8 on the starting position board) are referred to as ranks.

3. A straight line of squares of the same colour touching at the corners is referred to as a diagonal^[6].

4. A player may not move a piece to a square containing a piece of the same color^[7].

5. One may not move one's opponent's pieces. (Sorry.)

6. A player may move a piece to a square containing an opponent's piece; the opponent's piece is said to be captured and is removed from the chessboard as part of the same move^[8]. All pieces move the same way whether capturing or not, except the pawn.

7. If a player's king is attacked by an opponent's piece, that player's king is said to be in check. ^[9]

8. A player may not make a move such that after the move, his king is in check. ^[10]

9. A piece is said to attack an opponent's piece, or a square, if it could capture an enemy piece placed on that square were it the player's move, without regard to rule 1.B.8; that is, the piece attacks all squares it could capture a piece on were it its player's turn to move and were its friendly king temporarily replaced by a friendly pawn (so that king safety was not a problem)^[11].

10. A bishop may be moved to any square along any diagonal on which it stands^[12], so long as it does not move beyond another piece on that diagonal^[13].

11. A rook may be moved to any square along the rank or file on which it stands^[14], so long as it does not move beyond another piece on that rank or file^[15].

12. A queen may be moved to any square along the rank, the file, or any diagonal on which it stands^[16], so long as it does not move beyond another piece on that rank, file, or diagonal^[17].

13. The knight may be moved to any of the squares nearest to that on which it stands but not on the same rank, file, or diagonal ^[18]. This essentially means that it may be moved two squares along the file it is on, then one square along the resulting rank, or two squares along the rank it is on, then one square along the resulting file. It may jump over any intervening pieces, as long as the square it finally winds up on is not occupied by a piece of the same color.

14. The pawn may be moved one square forward on any move, unless an enemy piece is on that square, in which case the pawn may NOT capture it.

15. I'll finish this later.
