Mate in 2

Anti-Circe

This week, we make a rare foray into the world of fairy chess, with an example of the Anti-Circe condition. In this form, a capturing unit (K's included) is replaced on its square of origin, with the captured piece disappearing from the board. For example, a capture by the white queen sees that piece immediately reborn on d1. A capture is only legal if the rebirth square is free. In the case of a king capture, the e1/e8 square must be both free and not guarded by an enemy piece. Note that rooks and knights are reborn on the same colour square as the capture takes place, eg. a wS capturing on b4 reappears on g1, a BR capturing on f3 reappears on a8, etc.

In the above problem, we have a mate in two, with the Anti-Circe condition. Note that as the position stands, the move 1...Kxh2 is illegal, as the e8-square is presently guarded by the Bh5, but if (for example) the bP were on g6, then the capture Kxh2 would become possible.

Any comments or questions on this problem should be addressed to Steve Giddins (our Libarian and Archivist) using the 'Contact' item in the menu on the left.
