Neutralizing the application of a technique against you by disrupting the optimal distance from which it is applied.
We initially learn about distance in the context of a street fight: “Whoever manages the distance manages the damage.” This principle also applies in non-striking encounters. Once you understand the optimal distance required for the successful application of any technique (submission, sweep, guard pass, positional advancement, escape, etc.), you can use that understanding to disrupt the opponent’s distance and neutralize their effectiveness.
