Salkkuman: There doesn't seem to be an official set of checker rules - like there is for chess. Some rulesets seem to have a '40 move' rule, which says that if one players <em>appears</em> to have an advantage, his opponent can ask for a judgement. If the player having the advantage can't convince the referee that he can make progress in the next 40 moves, the game is a draw.

Personally, I'd say that on BK any non-dice game a result (usually a draw) should be declared if a position repeats itself twice. Games that can have positions that repeat themselves include most (excluding Dark chess) chess and checkers variants, Alquerque, Jarmo, Jungle, Tablut, Tank Battle, Halma, Hasami Shogi, and Espionage (although in Espionage, positions should only be equal if exactly the same pieces are on the same fields, not just pieces of the same rank, because of the opponents not knowing the rank of all the pieces).

This however may not be easily programmed.
