To effectively handle an opponent who relies heavily on speed and aggression, it's essential to remain composed and strategic. Utilize your defensive skills to absorb their pressure, focusing on maintaining proper positioning and anticipation to minimize their impact. Employ quick footwork to create space and maintain distance, allowing you to counterattack when they overcommit. Additionally, varying your pace and employing feints can disrupt their rhythm, while capitalizing on their aggressive movements to create openings for more precise strikes or plays. Staying mentally focused and adaptable throughout the match will help you turn their speed and aggression to your advantage.
