Nara Shikamaru

[Celena]

In terms of power, yes. In terms of strategic ability and planning, Shika beats Naruto by a long shot, and Kabuto by a decent margin as well. That's how he would beat them. When you can predict how your enemy will move, there's no way for them to beat you.

In terms of strategic ability, Shika's the best period. That doesn't mean he could beat them, he just has the advantage intelligence wise. Don't forget, naruto probably has twice as much chakra as Shika. He wouldn't be able to keep up. Even when he fought Temari, he gave up due to lack of chakra even though he had her on the ropes.
