Main Lane

Main is the shortest route and the one sightlines concentrate on most, so you get chipped down by spam; you combine side / high ground lanes with it to make Splits and rotations work. The allocation of how many bodies go to which lane is the language of macro judgment itself, and it is the terrain premise behind crossfire and Split. The defenders' basic shape is to concentrate sightlines on main while dividing up coverage of the flank lanes; the attackers apply pressure from flank to break main's sightlines and collapse the choke. Everyone sharing which part of the map is main and which is flank is the foundation of every formation call.

As the initial positioning setup, share before staging who takes main and who goes flank. The read of whether to run the flank while the enemy is stacked on main, or make them answer the flank and push main through.
