To start the enchantment, a curiosity
#1 AntiCirce duodecuple check
the capturing piece is reborn on its original square if it is empty, otherwise the capture is illegal.
an exception however when the square of capture and rebirth are identical :
the capture is possible in Calvet type and illegal in Cheylan type

serial r#5
when one side has the opportunity to checkmate in 1 move, it must execute it.
< the side that starts plays a series of moves in a row
Here, the series of moves must be played with white without putting himself in a situation of mate in 1 move

Notwithstanding the AUW (and the great economy), this problem was ranked 4th (behind the Bourd, that is, but also behind two
poor problems) by judge Mladenovic, because there is only one white mate instead of two. Still the "thematic imperatives"...
#2 with lion-piece
: piece needing a sautoir to move.
the path must be free between the start square and the sautoir.
The same applies between the sautoir and the landing square, which may nevertheless be free or occupied by an opposing piece

hs#3 Take&Make with Nightriders
if a piece performs a take, it is required to perform a make
complementary with the march of the captured piece
white plays and black helps them until move n-1
then, on move n, the statement becomes selfmate 1 move

In (invented by R.Bédoni) if one side plays a piece,
the opposite side cannot play in reply a piece of the same kind.
