Kanepi builds up her game around her powerfulgroundstrokes. Her serve is considered to be one of the strongest on the WTA Tour. Kanepi frequently hits 170 km/h to 180 km/h serves. She generally serves away from her opponent but sometimes prefers to hit a powerful body first serve in order to push back and pin her opponent behind the baseline. But on occasions her serve can break down, which affects her game. In 2008, she began to improve her volleying skills and under her coach Luca Appino begun to use sliced backhand more often, thus making her playing more versatile.[citation needed]
She likes to return serves mainly with her backhand which she hits flat and tries to position herself to receive with backhand but is also capable of hitting good service returns with her forehand as well. She generally ends points early but she is capable of playing long rallies and reducing her unforced error count. Overall, she is anoffensive baseliner but depending on the game situation and scoreboard Kanepi can play a more defensive game.
