rinnegan aside itachi can't use susanno for a consecutive 15minutes(izanagi(10min) and kamui(5min)) and getting caught in a technique like izanami(not a battle tech btw) is quite redundant since madara taught him ALL uchiha kinjutsu. itachi most likely learned the tech from obito.
amaterasu is useless against obito. and i doubt he'll get caught in tsukyomi.
wrong, obito wood style weak against any type fire, but amateratsu is also fire, that sasuke thing was just for defense
and itachi wasn't there to make sure it was potent enough.

I don't think its useless he just disposed of it easy,:| had itachi been there after it was cast he could have got obito in genjutsu ..idk
really itachi can beat obito? We know obito can go intangible and because of that he can allow chakra to go through him thus he can walk through chakra. he could easily walk through susano'o and kamui itachi inside. Totsuka isn't hitting obito either and like I said yata mirror would work either. Foxy state itachi has eyes... Obito has ms and rinnengan plus he was trained by madara, he has some strong form of battle tactic. minato dateable
itachi will let obito think he is about to beat itachi when he slips through susanoo, itachi will genjutsu him, maybe even with izanami, or tsukunomi, obito has no genjutsu for tsukunomi, plus itachi could set it up with a strike form his sword that he barely uses but is very skilled at it when he needs to be.
Itachi has no counter for, Six Edo Jins and Obito's Intangibility. Obito knows nearly everything about Itachi while Itachi doesn't know anything about Obito.
itachi knows somethings about obito, obito just kept some secrets from him

I think kabuto told the edo jinchuriki to obey obito's orders maybe, or obito put them under genjutsu, although he has the mazou....
the Edo Jinchuriki were Kabuto's doing. but I doubt obito knows about totsuka(maybe, maybe not)
he doesn't need all of that. kamui and a spare sharingan is enough
does obito change eyes during battle though, (maybe vs konan) did he, itachi can read people well in all aspects
Of course he can, Minato is a given though.
thanks
I agree that he can beat Minato but not Obito.
that's right kiddos

you two have good minds I can tell
