Side control is the bedrock of your top game. Your body controls his shoulder line at a right angle while constantly killing his hips. It's the most stable position you land in post-pass and the central hub of the entire top game: from here you open the road to mount, north-south, the back take, and the full catalog of submissions (kimura, americana, paper cutter, kata-gatame).
Its real value isn't in hunting submissions, it's in pressure. The attack shows up on its own when a gassed-out opponent starts scrambling to escape. Side control teaches the fundamental rule of the top game: build weight and kill space first, hunt the submission second. Without owning this position, the rest of your top game is just guesswork.
