Original Problems, Julia’s Fairies – 2015 (II): July – December →Previous ; →Next ; →List 2015(II) Please send your original fairy problems to: julia@juliasfairies.com |
No.592.1 by Igor Kochulov – An improved version to No.592 (JF-2014/III); the problem wasn’t included in the Award JF-2014/III (“unfortunately with a flight-taking key”, K.Widlert), and a new version will participate in the current competition. (JV)
Definitions:
Einstein Chess: All units (Ks excluded) change their type when they move, according to a precise pattern. For non-capture moves: Q>R, R>B, B>S, S>P, P remains P. For capture-moves: R>Q, B>R, S>B, P>S, Q remains Q.
Anti-Circe (Anti-Circe Calvet (the default type)): 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 allowed. Game array squares are determined as in Circe.
Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.

A lovely long key to make way for the wQ. The bK is not in check, because Bxf6=R[wRf6->a1]? is not possible with the wQ on a1. However there is no threat, because wherever the wQ moves it allows the bK to escape, as follows:
2.Qg1 Ke7! 3.dxe7=S[wSe7>g1]?
2.Qf1 Kf5! 3.Sxf5=B[wBf5>f1]?
2.Qe1 Ke6! 3.Kxe6[wK>e1]? (and 3.Bxe6=R[wRe6>h1]?)
2.Qd1 Kxe5[bK>e8]! (or Kxg6[bK>e8]!) 3.Rxe8=Q[wQe8>d1]?
2.Qc1 Kg5! 3.Sxg5=B[wBg5>c1]?
2.Qb1 Kf7! 3.gxf7=S[wSf7>b1]?
Black is in zugzwang, because each of his possible moves blocks one of the bK’s escape squares. The combination of EinsteinChess and AntiCirce gives very complex and interesting effects (I had to use a computer to work out what was happening)!
Thanks, Geoff!

The rest of us, even those with the hard and soft ware, are too lazy and depend on commentators like you! 😉 I too couldn’t fathom what was going on.
You had given an equally good description for the original version too!
The author has switched from Chameleon pieces to Einstein chess. Aren’t the two positions sufficiently different to justify independent publication of this position? Rather than as a “version” of the previous?
Yes, Shankar, it’s a version of No.592. I’ve written it in the comment by haven’t mentioned above the diagram, sorry, corrected! And I was really awaiting (hoped for!) Geoff’s comment here. Thank you, Geoff!
A very harmonic setting of the theme! It was a good idea to replace the original chameleons with Einstein Chess. Had this version been published last year, it would indeed have appeared in my award.
The pieces on the last row all have active functions (but wBg8 only before the key), but they all also crucially block rebirth squares to stop some black checks and captures.
It is a little “annoying” ! : The begining position is illegal following Winchloe. And for me it is MUCH MORE LOGICAL !
Black King is in check. Only after the “capture” of the King, white Bishop transforms in Rook. Note that if you put a piece in c1, the position becomes legal.

The question is whether a capturing piece transforms à la Einstein before or after rebirth à la AntiCirce. Popeye transforms before rebirth, and WinChloe after. I can’t say that one is more logical than the other, but the Py interpretation perhaps seems more interesting…
WinChloe has a condition “La promotion précede la capture”, which is needed for problems that use Popeye’s interpretation of Couscous Circe. It would be good if WinChloe had a similar condition for transformation preceding rebirth.
