Harry Potter could outsmart everyone by being adaptable. He doesn't stick to one way of doing things. If a plan fails, he quickly comes up with a new one. He also uses his reputation to his advantage. People expect him to act in certain ways, so he does the opposite sometimes. For instance, if everyone thinks he'll fight a duel in a traditional way, he might use the environment around him in a creative way to win the duel instead. His creativity and flexibility are his greatest assets in outsmarting everyone.
One interesting strategy could be his use of misdirection. He might make others think he's going one way while actually doing something completely different. This keeps his opponents guessing.
In this fanfiction, Harry might use his knowledge of different magical cultures. He could combine spells or magical items from different traditions in ways that others haven't thought of. For example, using a spell from the goblin magic system along with a common wizarding spell to create a new and powerful effect. Also, Harry's ability to form alliances with unexpected characters could be a great strategy. He could team up with a character who has a special ability or knowledge that helps him outsmart the more powerful and obvious enemies.
