Grips
Competitive table tennis players grip their rackets in a variety of ways. The manner in which competitive players grip their rackets can be classified into two major families of styles. One is described as penhold, and the other shakehand. The Laws of Table Tennis do not prescribe the manner in which one must grip the racket, and numerous variations on gripping styles exist.
Penhold
Penhold styles have suffered in recent years due to their inherent weakness on the backhand side. This weakness makes it much harder for penhold beginners to perform well against their shakehand counterparts. However, this has not stopped the top penhold players from winning the World Championships, the World Cup and the Olympic games regularly, as the backhand weakness can be covered adequately with excellent footwork, or supplemented with the recent reverse penhold backhand loop innovation.
Shakehand grip
Possibly the oldest surviving grip since the table tennis racket took its current shape. This is similar to a tennis grip with the index finger extended over the racket head perpendicular to the handle. This grip allows almost even power distribution over forehand and backhand shots, but has a wider crossover point in between.
Virtually all European players and roughly two thirds of Asian players use this grip.
Unusual grips
Although the vast majority of the players grip the racket in one of the two styles above, there are some curious grips that have not proven their effectiveness in the higher level yet, and are very rare.
V-grip
An experimental style being developed in China, it is held by forming a "V for victory" sign and gripping the blade between the forefinger and middle finger while having the other fingers rest under and on top of the handle; it requires a modified blade to grip successfully. This grip produces a noticeable spin benefit due to the longer lever and mechanics utilized in the forehand and backhand (much like those found in the Western grip in tennis).
Seemiller grip
A grip that was made famous by Dan Seemiller, an American champion. This grip is a variation of the shakehand grip, but closely resembles the western grip used by many tennis players. In the Seemiller grip, the tip of the forefinger is placed so it reaches near the edge of the bat (or, in the case of another American champion, Eric Boggan, actually wraps around the edge of the bat). This enables Seemiller-grip players to get tremendous snap on their forehand strokes. However, it also makes it awkward to hit shots using a traditional backhand, using the opposite side of the racket. So, instead, Seemiller-style players hit their backhands with the same side of the racket as they hit their forehands, turning their wrists over the way a baseball player would to make a backhand catch, and typically blocking or counter-hitting the ball. Since they would otherwise use only one side of their racket to hit all their shots, Seemiller-style players often put a rubber with very different playing characteristics on the other side of their bat, commonly a low-friction "anti-spin" rubber that they use to return spinny serves or to abruptly change the pace of the ball during a rally. Seemiller, in fact, is credited with virtually inventing the combo bat, a racket with different types of rubber on each side. This grip also has the nickname "windshield wiper" due to the motion of the backhand and forehand.,
Penhold styles
Looper
Penhold loopers utilise the forehand topspin loop as their primary shot. This type of player usually exhibits excellent footwork, trying to use the forehand to cover the entire table. Compared with shakehand loopers, penhold loopers have a shorter reach and try to stay close to the table even during power exchanges. Notable penhold loopers are 1981-83 World Champion Guo Yuehua, 1988 Olympic Gold Medalist Yoo Nam-kyu, 1992 Olympics Men's Doubles Gold Medalist Lü Lin, 1992 Olympics Bronze medalist Kim Taek-soo, 2001-03 World Men's Doubles Champion Yan Sen, 2004 Olympic Gold Medalist Ryu Seung-min, 2008 Olympic Gold Medalist Ma Lin, 2009 World Champion Wang Hao, and 2015 Men's and Mixed Doubles Champion Xu Xin.
Counter Driver
The penhold advantage of a small crossover is fully utilised in this style. Staying close to the table, counter drivers block and drive the opponent's topspins back across the table at speed, trying to force them out of position or look for the opportunistic forehand kill. Counter drivers usually have a safe forehand loop as well, in case the opponent is a chopper and doesn't give topspins or easy kills readily.
Pimpled Hitter
The traditional penhold style. Pimpled hitters play over the table, hitting the ball as soon as it bounces off the table with the pimples taking care of most of the problems caused by the opponent's spin. The aggressive attacking can win points easily in the first few returns, but the lack of a topspin Magnus effectmeans that the attacks are less effective when the opponent is forced back.
Notable penhold pimpled hitters: Liu Guoliang, Jiang Jialiang, Toshio Tasaki, Yang Ying, Gwak Bang-Bang, Seok Eun-Mi, He Zhi Wen, Lee Eun-Hee, Wang Zeng Yi.
Shakehand styles
Looper
Shakehand loopers apply pressure and win points primarily with speed and spin loops from the forehand. After the opening exchanges, when the first attack has been made, loopers will attack with a variety of topspin shots varying in speed and spin, maneuvering their opponents around the table and looking for outright winners. The power and reach of a shakehand looper means that they can counterloop even when forced back from the table, which can be quite a spectacle when a lobbing looper forced back by smashes suddenly attacks in an attempt to regain initiative.
All-round Attacker
Like a looper, the all-round attacker uses the loop as a primary weapon. In addition, an equally effective backhand increases the chances of having the first attack, and the number of angles that could be attacked. While this potentially means that the player could get confused whether to attack using the forehand or backhand, most players tend to use the more powerful forehand, making all-round attackers not that different from loopers.
Counter Driver
The shakehand counter driver blocks and drives various attacks back at the opponent, forcing errors through changing angles and rhythm. A series of quick drives and blocks between counter drivers can look quite impressive, with balls seeming to fly everywhere. Female players seem to have more success with this style, possibly because the style "borrows" a lot of power from the opponent and doesn't require as much arm strength to achieve the same speed.
Attacking Chopper
The single most distinctive style in table tennis is the attacking chopper. While other styles look to attack and gain initiative, the chopper gives up the initiative, uses the chop to return an attack with backspin, making it necessary for the opponent to start the attack all over again. The defensive chopper returns repeated attacks with slow, floating backspin chops executed as late as possible, taking as much time as necessary to tire out and frustrate the opponent. Chops can vary in the amount of backspin (from no spin to floating), sidespin (curving into the table or away from the opponent), or position, making it hard to continuously attack. If the opponent refuses to tire out or starts to play defensively, the attacking chopper can suddenly mix in a spin or smash attack, catching anyone who isn't fully alert and prepared. Reversed rubber is usually employed in the forehand, but the backhand is usually reserved for long or short pimples, which is much easier to control. Some players reverse their racket in order to use the pimpled rubber on the forehand, notable examples include Koji Matsushita, Svetlana Ganina, Irina Kotikhina and Viktoria Pavlovich, but some refuse to do that to keep their style simple, including Chen Weixing (Chen does use the inverted rubber on his backhand to attack, occasionally), Joo Se Hyuk, Ding Song, Kim Kyung Ah, Park Mi Young and Tan Paey Fern. Very few players choose to defend with reversed rubber on both sides, a notable example includes Wang Tingting.
Points between a chopper and an attacker are usually the easiest for non-players to appreciate, because of the slowness of the ball and the spectacular chopping style.
