3 Part Lesson — Marcelo teaches a very important lesson on Guard Retention with 2on1 Control: [I] While holding the 2on1, your opponent only has one hand available to grab one of your legs and pass to either the right or left. Regardless of the choices, use your free leg to capture his trailing knee with either a Butterfly Hook or Half Guard. [II] Once you have your opponent's leg trapped, begin elevating his base with your hooks to set-up any number of available sweeps. You may need to clear his grips first before inserting the necessary hook. [III] If your opponent runs around with his leg out of reach of the Half Guard, cut across his body and place your foot on his hip for Open Guard. Again, transition to the nearest or your favorite sweep; whether it be the Tripod Sweep, X-Guard, or Single-Leg X-Guard Sweeps.
