20 core positions to start from. Each one annotated with dominance, control depth, and the count of outbound transitions and downstream submissions. The other 100+ — every guard variation, every counter, every depth level — live in the app, with new positions and submissions added every week.
The top 20skew toward what most rolls actually look like — bottom guards and top control. Specialty material (foot-lock entanglements, leg-pummeling, crucifix variants) is under-represented here because most players don't open those doors. 100+ in-app fills out the long tail.
