With an 8, Lalo's only hands could be A-A-A-A-4, A-A-A-2-3, or 2-2-2-A-A
Meanwhile, Baku's could be 7-7-7-7-J, 8-8-8-8-7, 9-9-9-9-3, J-J-J-3-3, 9-9-9-6-6, or a wide variety of different three-of-a-kinds
Not sure why Kaji is so confident that Baku will win, since he can't possibly beat a four-of-a-kind of aces, can only beat 2-2-2-A-A with one of the five hands I identified, and can only win against A-A-A-2-3 with one of those hands or a flush.
Someone let me know if my math is crap.
