Hi. I just wanted to see if anyone here has played in this format before. One On One Doubles is a serve/volley game for singles players. The server must serve and volley on both serves. The point is played out deuce to deuce, ad to ad. A line is drawn extending the center service line to the baseline. I guess that it was created by a tennis coach, Ed Krass. I have played it once before here in Florida. I am playing again later this month. Just curious if anyone else has heard of it/played it. Thanks.
