The -14 & #1 stipulation means: retract 14 moves and than mate in 1.
Defensive Retractor: In Defensive Retractors, 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.
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 not allowed. 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.

Our problem was inspired by the article „Chasing the black King“ by Andreas Thoma in JF 2018. Thus we we'd like to dedicate it to him. As far as we know the problem shows with W5-W8/W10-W13 a record of 8 thematical KK-moves. (Authors)
Quite economical and beautiful K-chase with a draw pendulum at the end, with the traditional trick of an en-passant capture to ensure that White starts the pendulum so Black has to stop it. Note that 9.Pa5xPb6 e.p.? doesn’t work as 10.Kf6?? becomes illegal, giving Qa1 something else to do after the introductory play.
