I’m 63. I simply decided when I began here not to ask for undos, even on a misclick. I feel that it is my responsibility to click correctly. However, I will grant undos without prejudice, as I believe if someone is cheating, then it just makes me stronger to play against a better move. (Yes, people ask for undos sometimes when they realize they made a mistake—a long pause between the move and the request is a “tell.”) Admittedly, I don’t have much experience with go online, as I play largely IRL on weekends. Too tired during the week.
By the way, it must have been another Conrad who played with you. However, I am hoping to play some fast, unranked, practice games without rank restriction, which I’m titling “Anybody,” so maybe we’ll meet across the board one day.
