When playing table tennis sometimes you need to do a soft touch shot so the ball just makes it over the net. It should be as short and low as possible near the net. The best drop shot will bounce twice on their side of the table. With tenergy 05 it is also very good to have side spin on it curving away from the player.
It is best to use this skilled touch against player that have moved away from the table. They have often moved back because they are expecting a big power shot, from their previous higher shot. It's good to mix it in to stop players who love stepping back to rally.
