With the black king in the corner, the Nf5-Kf6 set up forces to win. Due to specific features of human memory, many perceive this as a new situation, but still it is nothing else than the Lg6 Rc8 set up, copied along the a1-h8 diagonal.

If one wants to compare this position with the one in the previous example, one should know that it is a mirror image of the Kf6-Rg5-Ne6 situation towards Kh7-Ra8.
