How a rally is constructed to force one weak ball

Points are built, not struck

The shot that ends a rally is usually the least interesting one in it, because by that stage the opponent has already been placed where he cannot defend. The work happens in the shots before, each of which either moves the opponent, changes his contact height or takes away his time. A player who tries to end the point from a neutral position is skipping that construction and relying on the shot itself to do everything.

That approach produces occasional spectacular winners and a much larger number of errors from positions that offered no margin. The alternative is to accept that most shots are preparation, and to judge them by what they force rather than by how they look.

Moving the opponent costs him more than it costs you

Every metre an opponent is forced to run is a metre he must run back, which means the cost of movement is doubled for the player being moved. That asymmetry is the engine of point construction, since a player hitting from the middle expends far less than one hitting from the corners. It also compounds over a long rally, so the same shot that was comfortably retrieved early becomes a stretch by the twelfth exchange.

This is why players who appear to be doing nothing dangerous can still be winning the rally, one recovery step at a time. The mistake is to move an opponent and then hit into the space he has vacated too early, before the accumulated cost has taken effect.

Contact height as a weapon

A ball that arrives above shoulder height forces most players into a defensive reply, because the racquet path that generates power is unavailable up there. Heavy topspin hit deep produces that height naturally, which is why it functions as an attacking shot even though it travels relatively slowly. The opposite tool is the low slice, which forces the opponent to lift the ball and removes the possibility of hitting down through it.

Alternating between the two prevents the opponent from settling into a preferred contact zone, and rhythm players are unusually vulnerable to it. Neither shot wins the point directly, which is exactly why they are effective at generating the ball that does.

Recovery decides the next shot

Where a player stands after hitting determines which shots he can reach next, so recovery is part of the shot rather than something that follows it. The correct recovery position is not the centre of the baseline but the bisector of the angles the opponent can now hit from where he is. That means a player who has hit a sharp crosscourt should recover further towards that side, because the opponent's available angles have shifted.

Players who always return to the middle are covering an average rather than the actual situation, which leaves them stretched on one side repeatedly. The habit is visible in whether a player's last step lands before the opponent's contact, which is the only way to be balanced when the ball comes back.

Recognising the ball you have earned

The whole construction exists to produce a short ball, and a player who does not recognise it wastes the work that created it. The cues are the opponent's contact point behind the baseline, a defensive body position and a ball that lands well inside the service line. On that ball the correct response is usually to move forward and take it early rather than to hit it harder from the same position.

Taking it early removes the opponent's recovery time entirely, which is a more reliable way to win the point than adding pace to a ball hit from deep. Players who hesitate on the short ball hand the initiative back, and the rally resets with all the accumulated advantage gone.
