Peter: Hi, Susan.
Susan: Hi, Peter. It’s Friday again. Anything particular you want to do at the weekend?
Peter: No, nothing particular in mind. Maybe tonight I’ll go to a pub with some friends for the happy hour. You know, drinks are half price at weekends.  And I don’t have to get up very early tomorrow. Saturday morning, that’s the time for washing my ear, doing the laundry and then going out for brunch.
Susan: That’s breakfast and lunch combined, right?
Peter: Yes, that’s it. You can spend two hours or more over brunch. It’s a huge meal. You can have all the breakfast things, as well as all sorts of lunch things, such as salads, chicken, pies, and fruit. It’s not expensive. You just pay seven pounds per person. For that you can eat as much as you like. It’s a good time for all the family.
Susan: Oh, that sounds good.
Peter: What do you usually do at weekends?
Susan: On Sundays I have a lot of newspapers to read.
Peter: So do I.
Susan: I sit in the garden, over a cup of coffee with a continental breakfast, and read the Sunday newspapers.
Peter: Relax. How about Saturdays?
Susan: Oh, I usually go to a club to play chess with some friends. I love the game very much.
Peter: It’s great fun, isn’t it?
Susan: Yes, lots of fun. I enjoy playing chess on Saturdays.
Peter: I’ve never played chess. But I’d like to learn it some day. Is it difficult to learn?
Susan: No, not at all. I can teach you if you like.
(A week later. Now Susan is teaching Peter how to play chess.)
Peter: Could you teach me how to play chess now?
Susan: Yes. It’s a board game played by two persons.
Peter: How many pieces does each person have?
Susan: Sixteen 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 with 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 as shown in the picture.
Peter: Oh, I see.
Susan: There are sixty four squares on the board. The rows of squares across the board are called "Ranks".
Peter: You mean the horizontal rows?
Susan: Yes. The rows of squares up and down, I mean the vertical rows, are called "Files". Lines of squares running diagonally are called "Diagonals".
Peter: How to move the pieces?
Susan: 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.
Peter: So, you are not allowed to change your mind?
Susan: No. Each player has 2 knights, a King’s Knight 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.
Peter: I have to remember this. What is the aim of the game?
Susan: 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 piece to capture the checking piece. When this happens it is called checkmate and the player with the checking piece, or pieces, wins.
Peter: I’m afraid I need a lot of practice. Thank you very much.
