Diagram Circe: A captured piece is reborn on the square it occupied in the diagram position.
Camel(CA): (1,3) Leaper.
Non-stop Equihopper(NE): Moves along any line over another unit of either colour to a square situated such that the hurdle stands at the mid-point between the Equihopper’s departure and arrival squares. The English (standard) Equihopper cannot pass over an obstruction other than the hurdle when playing along Queen-lines. The non-stop/French Equihopper does not have this restriction.

Please, correct the key:
NE_a_g3
Corrected, 1.NEag3! Thank you, Georgy!
Oops! Missed putting the py2web “display-departure-square” clause for the key.
But otherwise you’ve prepared everything perfectly for me! Very grateful!
Btw, {display-departure-rank} can be used here 🙂
Actually, {display-departure-file}!
Is it really worth it to use “secondary parity” to implement this idea? I understand that this allows to use “classic” fairy pieces, but Shankar Ram has to pay for it with array of pawns.
I’ll try to implement the same idea with black knights and white “superknight”. Diagram Circe is a must, though, as this condition is what makes the mechanics work.
