|Anti-Circe:||After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). Captures on the rebirth square are allowed in Anti-Circe Calvet and not allowed in Anti-Circe Cheylan. Game array squares are determined as in Circe: R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture; fairy pieces go to the promotion square of the file of capture.|
|stipulations||'Proca Retractor', '-N & #1'|
|-N & #1:||The stipulation means: retract N moves and than mate in 1.|
|Proca Retractor:||The one of the Defensive Retractors, where White and Black retract (take back) a given number of moves (-n moves), in order to reach a position in which a forward stipulation (e.g. #1, s#1) is met. Given a choice, Black will retract those moves that avoid or delay White’s goal. Unless otherwise stated, Black may defend by mating White through a forward move, if such an opportunity exists after one of Black’s retractions.|
The different kinds of Defensive Retractors only differ in the way uncaptures are handled, of course only legal uncaptures are allowed. In Proca Retractors the retracting side decides, if and what man was uncaptured.

After Dmitrij Baibikov's publication I feel sorry for taking the lenght record in Proca Retractor AntiCirce Wenigsteiner from JF. So here is my attempt to return it back.
