One Million Chessboards: Global Instant Chess

One Million Chessboards: A chess game with one million boards, global moves, and a scalable Go backend with optimistic updates, running on a single server and using websockets.

Here are a few insights based on the provided text:

1. The "One Million Chessboards" Project Leverages Scalability: Unlike the previous "One Million Checkboxes" project, this was explicitly built for scale, suggesting an emphasis on handling a large number of concurrent users and interactions.
2. Innovative Server Architecture for a Massively Multiplayer Experience: The project utilizes a single server with a memory-resident game state and concurrency handling to provide a seamless experience for a large number of players simultaneously, which is quite unique.
3. Client-Side Optimistic Execution & Rollback Enhance Responsiveness: The frontend optimistically applies moves and uses a rollback mechanism to resolve conflicts, resulting in a faster perceived response time for players, masking the latency inherent in a shared, real-time environment.
4. Strategic Use of Compression and Zoned Updates Optimizes Bandwidth: By compressing protobufs and delivering updates only for adjacent zones, the project significantly reduces the amount of data transmitted over websockets, which is crucial for maintaining performance with many concurrent users.
5. Cloudflare Caching Minimizes Server Load for Global Data: Using Cloudflare with low TTL caching for global data (stats, minimap) drastically reduces the load on the server by serving frequently requested information from the CDN, improving overall scalability and responsiveness.
