The first question: you start moving the smallest disk because it's the
only option. Then, moving it again would be a waste, so you must move
other disk. Given the disks on top on the other two columns, you have
only one option, so you do your move. And then, unless you want to
"unmove" and get back to the previous situation, you have no way out
but moving the smallest disk again.
As to the third, a almost good solution would be looking at
