He isn't beating them.

You don't think he was forced to use ms right away because of his blindness
we don't know if it was right away or not. Infact only the beginning and the end of the fight was shown. With the end showing sasuke using ms b4 kakashi.
That's true. I still think a non blind sasuke could take that kakashi. In a fight against the team though his best bet imo is to get kakashi to use kamui to save one of the others or himself. With kamui gone and kakashi in that tired state that leaves naruto as the only threat left. Honestly after seeing a lot of replies and being told that my timeline of the fight restricts sauce slightly more than I thought, it's getting harder for sauce to take this. I still think done right he could pull it off, I'm just not as sure of it as I was
Blind Sasuke wtfpwned Kakashi even Chidori = Rasengan try again brate
Blind sauce that fought kakashi used those damned fast arrows, he started using those in the danzo fight, my theoretical fight happens before danzo

i doubt it. Sasuke doesn't know about frs, or naruto's sage mode, or kakashi's kamui. So enacting a plan to force kakashi to use something he doesn't know about is laughable.
He could win.
Doesn't mean he'd win 100% of the time though.
He made a plan pretty quickly during the danzo fight. That being said what your saying works both ways, no one on team 7 knows about susanoo(nor him having it) or about him having ama
He only made the plan after seen izanagi multiple times.
Actually not true. Gaara told them everything, and they already saw amaterasu.
when did they see sasuke do ama prior to kage summit? When does gaara tell them? This fight would theoritcally take place before sasuke reaches danzo which was directly after he fights the 5 kage. Not arguing for the sake of arguing, seriously asking lol
they have knowledge of ama via the aftermath of itachi vs sasuke. They all saw the black flames. Then they have knowledge of sasuke's use via garra briefing them of everything that takes place at the summit which includes susanoo and his amaterasu use.
