No, I still don't understand Zubr's tactics. You need to minimize the $ of the frog as much as possible, but you're trying to execute someone else. And don't forget that executing a peaceful player now equals the loss of a city. Is that what you're trying to achieve?
In my opinion, Zubr is brilliantly eliminating Amka.
He was glitching when Ortonn was revealed, thereby exposing Luke.
He worked well with Ment, who was Vader.
Plus, he has been suspected for a long time, but then they stopped paying attention to it.
Even I was firmly convinced all this time that Leia was Kosha, and now I have three suspects, and, to be honest, I'm more inclined to think that Zubr is Mafia.
But I'm still not sure about that, and I would like to discuss this possibility with the others.
And by the way, it's stupid and pointless to execute Jabba now, IMHO; most likely, he will just be accumulating credits at night.
Because Leia, if she has a brain and doesn't want to lose, will interfere with Tarkin.

Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
