Following this solution, I have some questions & comments.
1. It sometimes does and sometimes does not show an automove.
2. Also it sometimes does and sometimes does not indicate "vn"
after a multi-card move. Why to both?
3. If you don't count the 2 automoves that it shows explicitly,
it actually solved it in 58 moves.
4. Most of the moves it made are very reasonable. Like my
55-step solution, there are are a couple of obviously redundant
moves, but otherwise the move selection looks pretty good.
