Problem 585: Vincenzo Tinebra - Fairy (Anti Circe, Grasshopper, Camel, Giraffe)
vincenzo.tinebra(30.05.2015) Nice three variation Series problem with Anti Circe effects. Welcome to Vincenzo Tinebra from Italy!
 
 
 
 
 
 
 
 
585
 
1.Bf5 2.Gg6 3.Ge8 Rd4#
1.Be5 2.GIf4 3.GIe8 Kf5#
1.d4 2.CAd5 3.CAe8 Ke5#
 
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; fairy pieces go to the promotion square of the file of capture.
Camel: a (1,3) leaper, e.g. a1>b4 or a1>d2
Giraffe: (1,4) leaper
Grasshopper: Hops on Q-lines over any one unit (the hurdle) to the next square beyond.

Three different black pieces block e8 so that white can mate near the BK immune from capture. The choice of mate by white is determined by which mating square is unoccupied by black! All very neat!
However, I wonder if so many types of fairy pieces are necessary for this basic Anticirce idea.

Dear Jan,
the first of improvements is clearly right and I will ask the editor
to change the position.The second is not right, because the checkmate
would even prevented from rebirth.
As for the position with four variants, I want to compliment you on the
effort, but I can not accept it for two reasons:
a) the Vao only serves to prevent a rebirth, a fairy piece that is only
a selfblock
b) the checkmate of the bishop it is even prevented by the defense of
the Queen and breaks the cycle of checkmate, controls and need non capture.
Thank you very much for the interest in my problem



best wishes
Vincenzo
