1 Part Lesson — Marcelo articulates on defending your opponent's advanced response to the Single Leg Control from Butterfly: [I] After stepping inside your Seated Guard, if your opponent attempts to remove his leg, you must be alert and read to follow his foot with your hook. However, you must also consider an opponent who is explosive in his movement or who works in combinations; be prepared to deflect your opponent away from landing heavily in your Reversed Half with a Back-Step. When he does this, stay connected by seeking his post-leg with your opposite hook and follow him over to finish on top.
