I'm kind of obsessed with this old puzzle. You need to move the piano to the lower LEFT corner by sliding the pieces.
Curious if anyone has done any math things with such tile puzzles?
It's easy to move it to the lower right, and possible but kind of hard to get it to the left.
I guess what I want to know is "why is it so hard?"
@futurebird Perhaps similar to the Tower of Hanoi puzzle, in which the solution entails moves away from the desired endstate?

easy solution
as a moving company, what you do is you break the piano by accident
voila, extra room
@benroyce @futurebird I was thinking that all you really needed to do was break the lamp and the clock. Moving companies do this all the time.

@futurebird This is Klotski. This specific arrangement is the "Pennant Puzzle". 2swap's video Adventures in State Space is pretty good, but I don't remember if it answers this question.

One of the simple Windows games I used to play a lot, "Klotski", was basically this.
Pretty sure I can solve it, but I'm getting lost trying to do it in my head.

This one's a version of the Pennant Puzzle, which was copyrighted in 1909. Probably made by the same company.

@futurebird @ChrisInToots I mean, clearly the fastest way to solve it is to *ask a professional mover*, right?
