The World Junior Chess Championship is an under-20 chess tournament (players must have been under 20 years old on 1 January in the year of competition) organized by the World Chess Federation (FIDE). The idea was the brainchild of William Ritson-Morry, who organized the 1951 inaugural event to take place in Birmingham, England. Subsequently, it was held every two years until 1973, when an annual schedule was adopted. In 1983, a separate tournament for girls was established. Each FIDE member nation may select one entrant except for the host nation, which may select two. Some players are seeded into the tournament based on Elo rating and top finishes in previous championships. The first championship was an 11-round Swiss system tournament. In subsequent championships the entrants were divided into sections, and preliminary sectional tournaments were used to establish graded finals sections (Final A, Final B, etc.). Since 1975 the tournaments have returned to the Swiss format. Originally the winner was awarded the title International Master if he had not already received it. Currently the winner receives the Grandmaster or Woman Grandmaster title, and the second and third place finishers receive the International Master or Woman International Master titles . Four winners – Boris Spassky, Anatoly Karpov, Garry Kasparov and Viswanathan Anand – have gone on to win the World Chess Championship. ==World U-20 Championship== : 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「World Junior Chess Championship」の詳細全文を読む スポンサード リンク
