Now Kurapika vs Chrollo can be fair enough to happen

I'm not claiming that I'm a good writer or anything, but Chrollo knows more about Kurapika's abilities, fighting style, personality, strengths and weaknesses. While Kurapika knows almost nothing about Chrollo, and it's unfair.

Hisoka vs Chrollo was a build up for this dystinied fight:

Both Hisoka and Chrollo fought publicly in Heavens arena. Later, Ken'i Wang (The underboss of Cha-R family) analysed Hisoka's personality based on his fight with Chrollo in Heveans arena. Which indicate that there are mostly some records are publicly available or at least have leaked in the Hunters' website.

So?

We know Kurapika is laser focused in gathering the eyes of his clan from these weird human part collectors, and it's almost excluded that he gave it a shot and watched the fight or even heard about it. However, what if he knew about the existance of the spiders in the ship? He will definitely do everything he could to protect the prince and gathering informations is part of it.

He is a nen genius, even if Chrollo's ability diversed and unpredictible. Some hints about his fighting style, strategies, holes in patterns and knowledge about his ability would definitely allow Kurapika to prepare well for this fight. In the other hand, Togashi gave Kurapika steal chain that will equalify the unpredictibility aspect of both characters, as both can use other nen users abilities and some abilities require only one use to finish the battle. So, even if Kurapika can use the stolen ability for one time, it's still a big threat in the hand of a nen genius.

My prediction is: Hisoka will not get the chance to fight Chrollo again due to many aspects including the Heil-ly coming chaos and the climax of the succession war. And Chrollo's goal to steal the Kakin's treasure (The seed urn, Lotus Anchorite, Sword of Good Omens) will consider as a huge threat to the royal family and mainly Kurapika. Which Kurapika could analyse and understand the reason behind why the phantom troupea are thiefs from the first place, and possibly understand that it might relate to some requirement for Chrollo's ability. I can definitely see Kurapika deducing that.
