Maintains a move history to handle the fifty-move rule and the threefold repetition rule. For the first rules, we just maintains one move count per series of move which doesn't eat a piece or move a pawn. For the second rules, we use two strategies, a fast but unreliable one and a second slower but exact. A. Use two 16KB table of counter address by table[Zobrist key of the board mod 16KB]. Collision can occurs so its only a good indication that the board can be there more than 2 times. B. Keep a compressed representation of the board in an array to be able to count the number of identical boards. View code on GitHub
