No.674 by Kostas Prentos – Excelsior + Valladao!  (JV)

Definitions:

Imitator(I): Every time a piece moves an Imitator (or a set of Imitators) moves simultaneously in an identical manner. An Imitator cannot move of itself. If an Imitator cannot imitate the move of a piece, the move is illegal. An Imitator may only pass through or enter an unoccupied square and cannot move off the board. Castling is imitated by decomposing into a King move followed by a Rook move.

 No.674 Kostas PrentosUSAoriginal – 26.12.2014 Solution: (click to show/hide) White Kb6 Pb5 Pf2 Black Ke8 Ra8 Sd8 Pb7 Pe7 Pf6 Neutral If3 hs#5                                  (3+6+1i)Imitator f3 1.f2-f4[If5] Sd8-c6[Ie3] 2.f4-f5[Ie4] e7-e5[Ie2] 3.f5*e6 ep.[Id3] 0-0-0 [Ie3] {[Ie3]!! } 4.e6-e7[Ie4] Rd8-f8[Ig4] 5.e7*f8[Ih5]=R + Kc8-c7[Ih4] # { (C+ by Popeye 4.69)} (Not: 2...e6{Ie3}?, because after White’s 5th move, the Imitator ends up on a different square: h6, instead of h5. In the final position, with the Imitator on h6, Black is neither in check, nor in Zugzwang and can defend with both 5…f5{Ih5}!, and 5…Kb8{Ig6}!) One more example which can be classified in the group of fairy problems featuring the en passant capture, that some find controversial. This time, the difference between the pawn moving one or two steps forward, is the square on which the Imitator will stand at the end. Excelsior and Valladao. (Author)

It’s nice to see why 5.exf8=Q(Ih5)+ doesn’t work. Well done, Kostas!
