What remains true throughout GST trap and roll?

• A. Take out the table legs (minimum of two) or block the leg
• B. Keep the head upright
• C. Always kneel
• D. Maintain eye contact

Answer: (A)

Disrupting the attacker’s base is central to GST trap and roll. The move hinges on breaking their balance by taking out or blocking their legs, which are the primary supports that keep them upright and able to drive pressure. By targeting the legs—at least two points of contact—you collapse their base, making it much easier to roll them off balance and gain control or disengage.

Why this is the best fit: removing or neutralizing two legs ensures their center of gravity moves outside their base, so they can’t replant or recover as you execute the roll. One leg isn’t enough to guarantee loss of balance, and that extra support keeps them from being controlled effectively. The other ideas—keeping the head upright, always kneeling, or focusing on eye contact—don’t address the fundamental balance disruption that makes the trap-and-roll sequence work and safety possible in practice.
