What is Correspondence Chess?

Correspondence chess is a slower-paced version of chess where players take turns over a longer period — often days instead of minutes. It allows for deeper calculation, real-life flexibility, and strategy over speed. Fortress Chess brings this timeless format into the modern era.

How Fortress Chess Compares to Other Platforms

Unlike platforms focused on speed chess like Chess.com and Lichess, Fortress Chess is built entirely around thoughtful, correspondence-style gameplay. We prioritize long-form games, meaningful stats, and a clean experience.
