"Kakashi vs. Itachi!!" (カカシVSイタチ!!, Kakashi Bāsasu Itachi!!) is chapter 260 of the original Naruto manga.
Itachi attacks Team 7. They avoid his fireball and Kakashi engages Itachi. Itachi tries to catch him in a genjutsu but finds that it is only a shadow clone. Having created an opening, Kakashi instructs Naruto to attack. He strikes Itachi with his Big Ball Rasengan. When looking at the dead body afterwards they discover that it was only a body double used remotely by Itachi, just as Kisame had done in his fight with Team Guy. Team 7 and Team Guy continue on to the Akatsuki lair, Akatsuki having bought the necessary time to continue Shukaku's removal from Gaara's body.
