Was 'Battle of Sexes' Rigged?

As I just turned 70 and know my time on earth is limited I’d appreciate an answer to my question. Years ago I watched on TV the “Battle of the Sexes” tennis match between Bobby Riggs and Billie Jean King. Just before the match it was announced that King would be able to hit to the doubles court while Riggs would have to hit to the smaller singles court, and also that he would only get one serve to her two. I cannot get confirmation of this. I have searched all over for a video of the match and it doesn’t exist. My question: was the tennis match played fairly? —Wayne
