| Circe: | Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal. | В жанре цирце (Circe) взятая фигура (кроме королей) не снимается с доски, а возвращается на поле (если оно свободно), занимаемое ею в расстановке фигур перед началом партии. Ладьи и кони возвращаются на поля того цвета, на котором они были взяты. Побитая пешка возвращается на линию, на которой она была взята. Сказочные фигуры – на поля превращений на линии взятия. Если поле возврата занято, то происходит обычное взятие. |

Solution: (click to show/hide)
(C+ by Popeye 4.61 (Author))
A new pure fairy idea “Logical en passant uncapture” (by analogy with the idea
“Logical uncastling” in orthodox s#9 and #6 of the same author):
1) initially the main plan is not successful immediately due to en passant capture;
2) nevertheless, at the beginning of solution, White allows Black to execute e.p.;
3) fairy “en passant uncapture” happens: both Pawns returns on its diagram
squares (for example, by dint of rebirth, as here);
4) despite the returns of both Pawns on its initial places, en passant capture
becomes impossible for some reason (here the reason is orthodox – pin, – but also
it can be pure fairy the one). So the main plan becomes successful.
Excellent original idea in Logical style. White pinning fails, so black is forced to pin himself 😀
