About

ChessTempo is a feature-rich online chess training and playing platform designed to help players of all levels systematically improve their game. The platform's flagship feature is its tactics trainer, offering over 416,000 rated puzzles with detailed performance tracking so players can monitor their progress and identify weaknesses. Opening training leverages spaced repetition to help users build and retain a solid repertoire, while the endgame module provides over 17,000 computer-graded positions covering essential technique. The unique 'Guess The Move' mode lets players step through grandmaster games move by move and get scored against the master's actual choices, providing a immersive way to study elite play. A searchable database of 5 million+ games enables deep opening research and study of specific players or positions. ChessTempo also supports interactive chess books — both purchased titles and user-created content — bringing structured learning directly into the platform. Real-time and correspondence play allow users to test their skills against others and track their live rating. A robust community forum, comment system, training diaries, and leaderboards foster engagement and peer learning. The freemium model gives free users access to core features, while a premium membership unlocks advanced analytics, unlimited problem attempts, and additional training modes. ChessTempo is ideal for club players, tournament competitors, and self-directed learners seeking structured, data-driven chess improvement.
