About Matthew Sadler
Matthew David Sadler is an English chess grandmaster, chess writer and two-time British Chess Champion. In 1988, Matthew appeared on the first ever episode of British TV show You Bet!. Sadler won the British Championship in 1995 at the age of 21 and again in 1997 (jointly with Michael Adams). He won an award for successfully identifying the opponent, year and result of memorable chess matches featuring Bobby Fischer by looking at random board displays. His was the best individual score of the five-man English team and so contributed significantly to England's first (and to date only) gold medal in a major competition.
