I know latency/desync and the resulting peeker's advantage has been talked to death but I still see a lot of posts and comments not knowing about it and how it works, so figured I'd throw together a quick single-image demo which hopefully makes sense to someone who hasn't heard of it before.
Hopefully this diagram effectively conveys the following information:
When you move in Tarkov, you are quite literally at least one step ahead of the enemy. Use this to your advantage by peeking and killing an enemy before they get the chance to see you.
EDIT: Added an example for dying behind cover, may add more.
