This is the same argument people give for why chess is so good

Of all FPS games I would say CS is the most “distilled” game of the genre. Simple mechanics, no heroes or power ups or anything. So maybe it is chess like in that way?

The only “chance” (besides spread) is information you don’t know. Playing for info and reducing those games of chance (or playing them into your favor) are how you do well in this game.
