Turnabout, Predicament…!! (一転、窮地…!!, Itten, Kyūchi…!!) is chapter 336 of the Naruto manga.
Shikamaru forces Hidan to abandon his Triple-Bladed Scythe and leads him away. Kakuzu is impressed by their tactics, remarking that fighting Konoha ninja reminds him of when he fought the First Hokage. He merges two of his masks to double their damage and attacks. Meanwhile, Shikamaru brings Hidan to a remote location and covers the area in explosive tags. When his shadow reaches its limit, Hidan attacks him. He gets some blood, obtains a link, and stabs himself in the heart. Shikamaru collapses and Hidan starts heading back to Kakuzu. He is unaware that Shikamaru tricked him into creating a link with Kakuzu, thereby destroying one of his partner's hearts instead of Shikamaru's.
