@299792458 It's not that big of an assumption in case both Champ and Travolta pass the second round, because it's pretty sure they'll stick to their strategy to use the certain pass. There's simply no benefit not to do so. So BK will definitely target one of them.
But when only one player makes it to the second round, the plan has already failed. So the usual mind game returns again.
In this chapter, Champ still chose to use the certain pass, and Baku saw through it since he targetted him. But he could have chosen to duel , and in this case, not targetting him would have been the right choice.
In fact, not only did I make the assumption Baku would always target him, but I also considered the last player standing would definitely choose the certain pass. So... yeah, in fact, these specific probabilities have no real meaning since they heavily depend on decision making and mind games. With someone as OP as the lie eater involved, it may be more of a 100% win ratio than a 50% one. XD
Also, there's still something I don't understand. (if anyone has a theory, I'd like to hear)
Why the hell did BK chose to duel in the very first game? I don't believe he seriously thought the banker would target him, since Tobita was higher on the stairs. He definitely knew it was a bad move, but did it anyway, probably to start a mind game of some sort.
As long as I don't understand this, I will not take for granted Baku making the obvious choice. Even with 200 bios at stake.
