By Christian Koskorelos When did you start tennis? In 2006 or 2007 I was jogging in the park and three guys asked if I would play doubles. I always enjoyed watching tennis on television but barely had played. I jumped in and from the start just concentrated on not making errors. It proved to be quite effective and to this day at a certain level, I believe it beats over 90% of the competition because people just cant resist going for an ill advised winner. Of course when your playing 4.5 and up you have to adjust accordingly with appropriate aggression.
