Ms. S. Y. Leung (left hand player) serves the ball with heavy backspin to the left side of the table (Mr. K. Y CHAN uses his right hand to receive the serve).
The tactic of the server (Ms. Leung) is to hope that the receiver (right hand player) will send back the ball with a push (下旋推送, 即是搓球); so that the server will follow up the ball with a loop and gain the upper hand.
If the receiver do that (i.e. send back the ball with a push), it is a passive return.
In this video, Mr. K. Y. CHAN returns the ball with a backhand flick.
It is an active return.
Viewing from the top, the two posts of the net and the landing point of the ball form a triangle. If the landing point of the ball is very near to one side of the table, we get a triangle with the least possible area. We call this situation - "a small triangle". In order to do this, the player should have a very good control of the ball.
If the backhand flick returns with little power, the server (Ms. S. Y. Leung) will follow up the ball with an attacking stroke (either a smash or a loop).
