Hertfordshire Chess Association (HCA) was formed in 1902 and organises chess activity for affiliated clubs and individuals throughout the county.
- Over-the-board inter-club league and knockout competitions run from October to June.
- The HCA currently has two county teams playing in the East Anglia Chess Union (EACU) and Southern Counties (SCCU) inter-county competitions, with the possibility to progress to English Chess Federation (ECF) national championships.
- Competitions for individuals are currently dormant, though it is hoped to resurrect these in the near future.
- New players, or players returning to the game, can contact clubs in their local area. Alternatively players may affiliate directly to the HCA as individuals, allowing them to play in county matches and individual competitions.
- The HCA does not directly organize junior chess activities, but supports other organisations that do. See the junior page for more information.
