     I'm Sam. My hobby is playing chess (棋) one of the greatest games in the world. My mom taught me

how to play when I was 7. She beat (打败) me every time for the first year. But then on my eighth

birthday, I won for the first time. I nearly always beat her from then on.

     It takes about a day to learn the rules (规则). But if you want to be good, you have to practice for

years. You don't need much to play chess-just a chess set (棋具) and someone to play with.

     Chess sets can be quite cheap, or very expensive. Some people collect chess sets as a hobby, but

some prefer playing.

     There is a chess club in our school, and we meet every week to play with each other. I'm the best

player in the club, and the captain of the school chess team. This year we won the All English Schools'

Championship (锦标赛), and I had to go up on stage (台子) in front of the whole school to collect the

trophy (奖品).

     I'm saving up my money to buy a chess computer. It's very expensive, but very good for practice.

In that way, I'll always have someone to play with. One day I will be the world chess champion (冠军).
