To counter an opponent with a strong forehand smash, I would focus on improving my positioning and shot selection. First, I would emphasize consistent deep shots to the corners of the court, particularly targeting their backhand side, which can be less powerful for many players. Employing a mix of spins—such as topspin and slices—can disrupt their rhythm and create opportunities to expose their weaknesses. Additionally, I would aim to stay alert and anticipate their movements to avoid being caught off guard, especially when they wind up for a forehand smash. Incorporating drop shots and well-placed lobs could also be effective, making it difficult for them to generate power while forcing them to play at the net, where they may be less comfortable. Finally, maintaining a calm mental state and focusing on controlling the pace of the game would help me stay competitive against their aggressive style.
