• "From 1950 to 1990, Tinsley had been the world champion of checkers whenever he wanted to be. He’d occasionally retire to work on mathematics or devote himself to religious study, but he’d eventually return, beat everyone and become champion again. In that 40-year span, he lost five total games and never once dropped a match." Brilliant article from Alexis Madrigal on the race to solve draughts/checkers, one man and his computer, and another man and his faith.
