Quickboy gives an unrealistically better result than autoboy and than anything else (in my opinion). It's impossible to achieve such a result manually, no matter how hard you try. The save is attached.

Click "pass turn" and wait for the pink player to attack the blue player's town.
Quickboy shows a victory and minimal losses (51 spearmen, 6 pikemen). However, if you run a full autoboy (do nothing at the beginning of the battle, press "a" and don't touch anything else), a defeat occurs.
That is, Quickboy is calculating something incorrectly. Perhaps the pink army is standing behind the walls and not entering the castle, and they are simply being shot at by the town's defenses, or maybe the hero isn't using the earthquake spell, or something else. But Quickboy clearly gives an unrealistic battle result.
