Playing on L-shaped maps.

All newcomers come to the forum with a sense of their own unreal coolness. This is natural; everyone comes here to show themselves. For a man, this is a normal phenomenon. And most of them quickly realize that they are playing quite poorly. And at this point, it is important what the person will do. Will they learn, or will they remain in their ivory tower?
But claims to an "authoritative" opinion without confirmation through actual gameplay look ridiculous and certainly do not fit the topic.
