Prepare to embark on a deep dive into the intricate world of designing a multiplayer Chess game system for an online platform. This experience simulates a real-world design interview you'd encounter at top tech companies, focusing on low-level design principles and core object-oriented patterns. You'll be tasked with conceptualizing, architecting, and visualizing a chess game system from scratch, ensuring adherence to the official rules of international chess while considering multiplayer functionality, game rules, and edge cases. This engaging and challenging exercise will push you to showcase your analytical thinking and design expertise.

Get ready to strengthen your design skills by:

• Developing a robust approach to decomposing a complex problem space.
• Applying essential design patterns to build a scalable and maintainable system.
• Listing and detailing core classes essential for the Chess Game.
• Illustrating class relationships using UML diagrams to ensure clear visualization of the system’s design.

By the end of the session, you'll be increasingly adept at structuring clean, efficient, and scalable software architectures for complex systems, enhancing your readiness for technical interviews and real-world engineering challenges.
