Learn the smash (kill shot) in table tennis: finish high balls hard and safely, with milestones, typical mistakes, safety tips and FAQ.
The smash (also kill shot) is a hard, flat stroke on a high ball. You play it when the opponent lets the ball bounce too high or too short and you have the chance to finish the point. It is not a standard stroke but the moment in which you convert pressure into speed.
The honest answer to "how important is the smash?": important, but not often. Modern match analyses show that many points are decided in the first three strokes: in an analysis of 244 top matches (1970 to 2021) the first three strokes were very important in all periods [3]. The smash comes later in the rally, when the opponent gives you a high ball. Footwork is central: in a study with 14 top players, among five strokes (backhand top, forehand top, forehand spin, forehand smash, flick) the leg muscles were most active in the smash, the forehand top and the forehand spin; the gluteus maximus and the hamstring reached 62.8 to 91.7 % of maximal activity across smash, forehand spin and forehand top, the calf muscles 67.1 to 92.1 % in the smash [1].
A note on context: there is little more on the biomechanics of the smash than this muscle activity data. Technique details below are therefore practical standard.
How long does it take? You understand the basic form in one session. Until the smash holds under pressure in a controlled way, expect weeks (practical experience, not a study).
A ball that comes clearly above net height after the bounce is your chance. The net is 15.25 cm high [4] – barely a hand length. A ball that comes clearly above it can be hit flat over the net; that is the prerequisite for the smash (practical experience).
Milestone: On 8 of 10 feeds you recognise before the bounce whether the ball is smashable.
Go behind the ball with small steps and turn sideways. The ball should not surprise you: whoever lets the ball come from behind has room to swing. The side step or the one-step bring you there; both have different load profiles [5].
Milestone: On 8 of 10 balls you are in position before the ball reaches its highest point.
The stroke begins with the legs: push off the back leg, turn hip and trunk, the arm follows. Leg muscle activity in the smash is high [1]. In a forehand study, nine advanced players were compared with eight intermediate: the advanced players had a larger contribution of lower trunk rotation to racket speed, while racket speed at contact did not differ significantly [6] – so the difference lies in how you generate speed, not in a "faster arm".
Milestone: You hit 6 of 10 smashes with rotation rather than only with the arm.
The smash is flat and fast, but it must land on the table. The target is a free corner or the opponent's elbow area (practical experience). Whoever always plays full throttle makes mistakes: at the end of sets pros chose safe stroke positions and offensive stroke types, not more risk [2].
Milestone: 6 of 10 smashes land on the table, 3 of 10 are direct points.
After the smash you go back to the table. The opponent can block or lob. Footwork is part of the stroke.
Milestone: After 8 of 10 smashes you are immediately ready again.
Watch when you convert smashes and when you do not. After each session note ten smashes: how many on the table, how many points, how many errors? Your personal ratio shows when the smash is the right choice. As orientation (not a study): if more than every third smash lands in the net or out, a safe topspin is better.
A hard, flat stroke on a high ball with which you want to finish the point.
When the ball comes clearly above net height after the bounce and you are in position. The net is 15.25 cm high [4].
No. Whoever touches the ball before it has touched his own court while it is above the table or travelling towards it loses the point [4].
Legs and trunk. Gluteal, hamstring and calf muscles were strongly active in the smash [1].
