I played a match last night, and during the middle of a rally my string popped. The center cross string popped. While playing with the broken string, I was able to hit some wicked top spins, almost a kick serve where the ball goes to one direction and bounces in another direction. I kept hitting like this until I won the point. My opponet stated that it was illegal that the momment I popped the string the game must stop and replay the point. He stated that playing with a broken string is like playing with a racket strung spegetti (sp) stringing because of the unpredictable spin one can hit with. So what are the rules exactly about this? Is he right?
