There was one where Naruto played multi-year 5d chess against Danzo and Madara. I loved the part where Konan broke into his underground base somewhere in the desert, and her file had zero info on how he plans to fight her compared to practically everyone else. I think the fic got dropped, but it was a very good story. I forgot the name, but it was on FFN.

Also, if you just like Konan in general there is a very good chinese fic: https://www.uukanshu.com/b/58399/ I suggest reading it with Google Translate (just use Chrome). This is a 1.35 million OC/Konan story with pretty good story and I consider it a pinnacle Konan-centric fanfic across en/cn/ru fics.

Source: I wrote relatively popular SIOC/Konan story before, but dropped it (100k+ words) so I consider myself somewhat of a Konan expert. Also, I've read all of FFN/AO3 Konan stories, Ficbook.net (russian FFN), and tried to find every Konan story on tuishujun and uukanshu (chinese FFN).
