Henrik Juel: C+ Euclide 1.01
This is an example of the retro theme of WCCT-11
The thematic square is b1, where Sb1 is not original, but promoted, and where Black promoted, only to have his promoted piece captured later
The fact that the promotions are both to knight is not required by the theme (2021-03-21)
