If you knew they were going to cheat, and you set traps to expose the fraud BUT didn't know how deep the corruption went, you would then just have to wait as long as possible to expose as many enemies as possible. A finishing blow by the enemy is when the enemy is closest to annihilation, so, you wait until the enemy thinks that they have won and becomes reckless with their final blow, and that's when your strike. He is waiting till the last moment, when they become cocky and reveal themselves from the shadows. Thats when he exposes them with a light brighter than the sun. The light of truth.
