About me

I played my first chess game in December 1977 and was lucky to hold draw. I continued to play chess and joined a chess club in September 1978. I'm still enjoying playing chess. I like to do many other things than playing chess. Long walks, some jogging, cycling, reading books, listen to music, watch movies, writing and much more. Life is fun!
