Rather Itachi fought seriously or not he battled him. Itachi let Sasuke get the upperhands risking biug moves so his disease could ware him out faster. Technically Itachi wanted him to kill him himself but the disease did that so Sasuke failed. I'll give you that Sasuke did pretty good but the difference being Itachi didn't want to kill him and Sasuke did and didn't actually, minus beat him so he just survived. And don't give me that its a difference between Kimimaro and Itachi case because they both died of sickness and didn't finish their battle because of that not because the person they fought.

Okay so they fought before. And I'm sure it was sure because they didn't show all of it. Either way Jiraiya didn't lose.
