Anti-cheat in classic CS 1.6

Over the past year, I have had a very difficult time playing CS2 with opponents who use third-party software. Personally, I always try to perform well, but in this case, it becomes impossible. Can you tell me where I can download Counter Strike 1.6 with built-in anti-cheat?

You know, I don't think Counter Strike 1.6 needs all these anti-cheat gadgets, because everyone who uses third-party software plays CS 2 😊 Moreover, if I'm not mistaken, this feature only works on your teammates, not your opponents. By the way, it's also available in the csget.me build, but I haven't used it yet. The thing is, I've been playing with my friends as a full team for many years. It started back in college when the classic CS 1.6 first came out. We immediately identified our strengths in the game and have been having fun like this once a week ever since.
