How do rewards work in games like Wari? https://en.wikipedia.org/wiki/Oware https://en.wikipedia.org/wiki/Oware
Sometimes it happens that a possible move captures pieces and therefore on paper brings you closer to victory, but also puts you in a strategically bad position (which is only apparent after subsequent moves) and will eventually lose you the game.

However, this yields the new problem of your reinforcement learner needs to explore all paths to all possible outcome - the exact thing we are trying to get around. Thus, we can use human heuristics or neural networks to try and learn these heuristics. The latter approach is deep reinforcement learning and the basis for Alpha Zero.
