a 10-game match was conducted between Freeling and three Havannah bots. Freeling won by +7−3=0, losing two games to Lajkonik (Poland) and one game to Castro (Canada). Hexdame exactly translates international draughts rules to a hexagonal gameboard, increasing options for moves and tactics, and reducing draws. The World Draughts Federation (FMJD) has actively promoted Hexdame as an alternative to the 10×10 game. Personal life On 13 May 2000 in Enschede, SE Fireworks exploded 120 meters from Freeling's home, killing 23 people, wounding 947, and destroying 400 houses including Freeling's. Although uninjured, all his possessions and game materials were lost in the tragedy. Freeling has three sons (Demian, born 1975; Myron, born 1978; Falco, born 1993) and one daughter (Ninja, born 1982). Demian invented Congo, a xiangqi variant, in 1982 when nearly 8 years old.
