The Wayback Machine is at best an unreliable, slow, and laggy way to revisit old versions of chess.com. At worst it doesn't work at all. Some of the categories have records that are simply unbeatable due to the newest versions of chess.com doing things such as adding more bots and changing bot ai. Having a split for the 2026/newest version would be nice to resolve this unless there is a way to make the wayback machine reliable that I am missing.
