What Episode Does Ichigo Fight Aizen

In which episode did Ichigo defeat Aizen? 3

Against Eisen in episode 308-310 ... but defeated Eisen in episode 309

In episodes 308 and 309, he sows to reunite Ichigo and his Zanpkot. A tense Zangetsu Zanpakut wraps his right hand, he uses this Aizen. Then, in the mid-309's, Achigo used the last Gitoga tenso that Tensa Zangitsu taught him when he forced him to teach his last Zinpact. He then uses Mugetsu to defeat Aizen and when Ichigo's powers are exhausted, Kisuke arrives and influences the O Spirit to seal the aliens with the Society.

He defeated Eisenhower in episode 309.

What Episode Does Ichigo Fight Aizen

From my point of view, the best game ever in Borichi's history
306310
Ezine 309 officially won.
308310, well, he learned the secret of the final Gatsuga tense and used this power to weaken the Aeschylus. So Urahara's magic will work, and that too.
Sorry for the inconvenience, the question needs an answer.
