The World Chess Championship is played to determine the World Champion in the
board game chess. Both men and women are eligible to contest this title. In addition, there is a separate event for women only, for the title of "
Woman's World Champion", and separate competitions and titles for juniors, seniors and computers. However, these days the strongest competitors in the junior, senior, and women's categories often forego these niche title events in order to pursue top level competition, although they continue to be part of chess tradition. Computers are barred from competing for the open title.
