Court of Appeals: Can a player return to a match after retiring?

At the 4-1 changeover my opponent said she wanted to retire. Shocked, I asked her if she was serious. She said yes. We shook hands. After this she went to the bench, sat down, then stated she wanted a Medical Timeout. She started arguing that when she shook hands, she was only thinking of retiring. Was the match over or not?—Amy Petrow, Tucson, AZ

Your opponent can get all the rest or treatment she wants now because this match is history. The Code, #2, says that shaking hands “is an acknowledgement that the match is over.” Note that this doesn't require a handshake for the match to be over, which is just as well in times of social distancing.
