Ibro recalled the short meeting with the other Ibro. That Ibro told him that he was trying to change the current situation. He didn't understand his deep meaning before now.
Yes, that move was an unpredictable one, so it succeeded. If Ibro managed to take the most unlikely course every time then he would avoid a lot of that enemy's schemes.
But such an approach would cause a lot of trouble as well. For example, the upcoming battle scenarios are a lot. If Ibro used the most unlikely one then he would suffer a lot of casualties.
The most unlikely course was to hit as many enemies as he could. That would increase his losses by a lot. Ibro thought about this battle.
If he was in his enemy shoes and he knew the decisions he would take beforehand, then it would be easy to set some traps to his troops. Ibro needed to conquer six strongholds and six underground forts to remove the lockdown curse.
