[Retros] destination squares

A few random points...

The end position for the 3 destination mate is also similar to a proof game
composed by Richard years ago.

The chess detection problems start on page 76 (out of 86) in this booklet.

The first Pal Benko problem is nicely paradoxical: because the initial
diagram is a sound #2 as well, without any retraction!

This sounds very similiar to question 6 of Masaya Nakamura's "Chess
Detection Puzzles", presented at the WCCC 2012 in Kobe, Japan:

"I saw a strange game yesterday."
"Again? How strange?"
"The game was ended by checkmate, and all White's and Black's moves in the
game were to one of three squares."
