I'm not sure that I chose the right sub-forum....so if it's wrong please move it where it belongs.
It's about the first example:

That's how I see it:
We assume that BB has either A5 or K5, so we take out A and K from flush and remaining 3 K from a gutshot out, because that cards would complete his full house.
But that leaves us with 7 outs, and in article it says 8...
I've been with many possible opponent hands, but I can't get 8 outs. Did author made a mistake or am I missing something?
I would have posted this in comment but I'm not sure anyone checks the regulary so I posted here
hope it's not wrong
