To counter an opponent's strong backhand flick, first, anticipate their shot by positioning yourself a bit closer to the table, giving you a quick response time. As they prepare for the flick, focus on maintaining a low and balanced stance, ready to pivot. When they strike the ball, aim to use a combination of placement and spin; direct your return to their forehand side, as many players have a weaker forehand response compared to their backhand. Additionally, you can vary the pace of your shot, using a softer touch to draw them in and then springing back with a sharp topspin drive. By mixing your shots and keeping them guessing, you can effectively neutralize their backhand flick.
