PLAYING CHESS
0 In your last letter you asked me to tell you why I like playing
00 chess so much. Well, I nevertheless think it is because chess gives
me a feeling of the excitement. I am quite competitive and like
me challenge of playing one-to-one. It gets intense sometimes;
in a game you can get extremely nervous and excited and have all
sorts of emotions. If I have played such a good player, put up
a good fight and lost, then that is too satisfying, but it is always
better than to win! There is also a good social side to chess. I
have made lots of friends at playing in competitions across
Europe. It is really interesting seeing cultures more different from
mine and trying to practise other languages! Now I play most of
weekends and holidays, but I do not know for certain if I will continue
to take part in competitions. During the last couple of years while I
have had more schoolwork, in which makes life more difficult. You
have got to be an extremely ,good player for chess to be so financially
worthwhile. However, I would like recommend it as a hobby to
anyone. If you are interested, you should to join a chess club at once.
