No.277, 278 – Two very exotic problems by Chris Feather! Enjoy a combination of fairy conditions Anti-Kings+Anti-Circe and author’s explanations to the problems! I’m also grateful to Chris for the definitions he’s sent with his problems! (JV)


Anti-Kings: A king is in check if he is not attacked. Mate occurs when a  king is not attacked and his side has no move which exposes him to attack. (Of course kings may not be captured.)

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). R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture.

    What a terrific idea! Another interesting possibility is:

    h#2 (b)bKg8>e4
    white kg1
    black kg8
    neutral pf7 ph2

    (a) 1.nPh1=nR nPf8=nR+ 2.nRh8+ Kh1#

    Now Black cannot play 3.Kh7??, because the nRh8 doesn’t attack the bKh7, because the nR’s rebirth square (h1) is occupied. For the same reason the bK cannot play 3.Kxf8?? or 3.Kxh8??, because it would be reborn on e8, which is a white-coloured square.

    (b) 1.nPh1=nQ nPf8=nB 2.nBb4 Kxh1[wKe1]#

    Anti-king is a very interesting condition. Chris has shown two excellent ideas in combination with Anti-Circe ! Thanks Chris.
