Ok I’m starting to understand this now, I kept on wondering how working with angles in these games function, for the most part it’s a matter of distance, two people equidistant, one holding at a corner close to an angle while the other one is moving far against the wall and slowly working around that angle, that person walking up would technically win according to your 4th example. But anyone far away holding an angle against someone across whose very close to that angle working their way up would win because they have a more precise degree of visibility to play with than the on comer. This is actually blowing my mind a bit. Definitely gonna change the way I play and look at these maps now.
Oh shit I might actually need a 2nd illustration on your 3rd example there cuz they’re playing with 2 very tight/similar angles.
