St. Thomas Becket
The 12th-century Archbishop of Canterbury
played a lot of chess with his best friend, King Henry II. The two were said to have "but one heart and one mind," but were in conflict over the Church's rights and privileges. His eventual assassination, wrongfully in the king's name, led to Henry making a public penance at Becket's tomb.
