The best way to memorize the solution is to watch for the moves of the large square (prisoner) and split the solution into different phases. Each phase prepares a single move of the large square. Also, it is recommended to memorize special positions like the one with the four vertical pieces in the top position. I am pointing out these things in the video. Have fun.
There are other solutions with less moves, see e.g. [ Ссылка ]
