The hole in the summer

Checkmate in Moves

In the United Kingdom, the "silly season" is a period in the summer months known for frivolous news in the mass media. In Germany, this period is called "Sommerloch," which can be translated as "summer hole." In the past, this was used to describe the lack of relevant news during this time. From today's perspective, this sounds almost absurd. Without giving too much away now, in one of the variants to solve the puzzle, creating a gap is the only way to solve the difficult puzzle. But the algorithm does not always parry in the same way, can you close all the gaps? Good luck!
