Dear OLEG-USSR is a dirty player in speed map Walkthroughs with extensive experience. The fact that he hasn't played it only says one thing — he is simply NOT interested. Moreover, there are rules for offline games; an entire culture has been formed for such games, not just out of the blue. And this wasn't done in a single day. If you consider yourself worth something, skilled, etc., try playing in a real offline tournament, or take any map and try to repeat the best result or surpass it.
When you realize how difficult all of this is, and how far your result is from the finalists, then you will understand your level and what you are actually dealing with. The results will upset you, but that's the truth of life.
That's how it is )
