J: I enjoy playing chess. Some of my friends are good players.
S: I’ve never played chess. But I’d like to learn it some day. Is it difficult to learn?
J: No, not at all. I can teach you right now if you like.
S: Of course. Go ahead.
J: Well, it’s a board game played by two persons.
S: How many pieces does each person have?
J: 16 pieces. Each player has 2 Rooks, 2 Bishops, 2 Knights, 1 King, 1 Queen and 8 Pawns. One person uses the light coloured pieces and the other plays the dark coloured pieces. The colours are always called "White" and "Black", even if they are cream and red. At the beginning of the game, the pieces are set up on the chessboard. Here is a piece of paper, I can draw it for you... Like this.
S: Oh, I see.
J: There are 64 squares on the board. The rows of squares across the board are called "Ranks".
S: You mean the horizontal rows?
J: Yes. The rows of squares up and down, I mean the vertical rows, are called "Files". Lines of squares running diagonally are called "Diagonals".
S: How do we move the pieces?
J: There are some rules. Each of the pieces has to move in a certain way. The players take it in turns to move their pieces and can move only one piece in each turn. Once you have touched a piece, you must move it. After you have moved it and taken your hand away, you must leave the piece where it is.
S: So, you are not allowed to change your mind.
J: Each player has 2 Knights, a King’s and a Queen’s Knight. They are shaped like a horse head. The Knight is the only piece which can jump over pieces. It can jump over pieces of its own colour, or over enemy’s pieces. The Knight can move in any direction, forwards, backwards or to either side, but it always has to move three squares at a time. When the Knight moves, it must go two squares in one direction and then one square to the side.
S: I have to remember this. What is the aim of the game?
J: Well. It’s to trap your opponent’s King, so it can’t escape being captured. That is, there are no squares for it to escape to, no pieces to protect it and no pieces to capture the checking piece. When this happens it is called "checkmate" and the player with the checking piece, or pieces, wins.
S: I’m a bit confused. I’m afraid I need a lot of practice.
J: Hey, why don’t you join me Sunday afternoon so that I can teach you on the spot?
S: That’s a good idea. Thank you very much. I will have to finish my essay before that, though.
J: Call me if you can.
S: I will.
