I was thinking if any move that would repeat a previous position were not allowed, the only game end conditions needed would be stalemate and checkmate. Presumably, players could recognize a long stalemate endgame and agree to a draw without having to play it all out.
Another less intrusive idea: give black a higher score for a draw than white, with the exact numbers adjusted to balance out white's expected score advantage.
