Of course, the very best way to help my new players (who have never played a match) learn how to use the Coman tiebreak procedure is to play using it. Weather has prevented us several times from playing several times, and our first match is looming. A year ago, I found a good explanation with a diagram online, but I can't find it now. It was not the one on the USTA site. I have the instructions without a diagram. I can't remember whether the explanation I saw was part of a video. Does anyone know where online to find a good explanation with a diagram for beginners?
