Modern Chess Website Design

I need a sleek, contemporary chess website with the following features: - Online multiplayer games - An AI opponent - Sections for chess tutorials and tips - Global and local leaderboards - Detailed game history and replays - In-game and global chat - Organize and join chess tournaments - Invite friends to play - Customizable board and piece themes - Options for timed matches Additionally, the website must have user authentication and profiles. Ideally, you're a web designer with experience in creating interactive gaming sites and can deliver a clean, user-friendly interface.
