???? Course Overview

Lachlan Giles delivers a methodical deep-dive into the 50/50 guard system, teaching how to establish control, nullify opponent options, and initiate high-percentage attacks. Emphasizing structure, timing, and intelligent positioning, this anthology reframes 50/50 from a neutral territory into a devastating offensive platform.

???? What You’ll Learn

Safe entry into 50/50, counter-grip strategies, balance control, knee alignment.
Attack Sequences & Leg Lock Chains

Positional Flow & Transition Mapping
From 50/50 to passing, back entries, sweeps; flow drills for grip resets.
