No.136 – hs#9 by Michael Grushko – Surprising echo-model mates in both phases! (JV)
PWC – When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank.
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, Qremains Q.
Republican Chess Type 2 : There are no Kings : if the side which has played can put the opposite King on a square where it would be legally mate, then the opposite King is put on such a square. The opposite side can then put itself the other King on a square where it is mated.

Thank You for your dedication, dear Michael!
I think that this three-men composition – with two super surprising model mates in distant parts of the board, is a unique problem! I hope that the readers can analyze in depth this phenomenon.
In set-play the final mate-position looks like:
In real play this beauty picture is repeated at the bottom of the board:
As it can be seen, none of the figures that stands at the beginning of the board, did not participate in these finals!! The work with three fairy conditions: PWC, Einstein Chess and Republican Chess 2, leads to this unique transformation of power.
Obviously, it is very difficult to achieve such effects – many people assume that such problems are composed with computer programs. This is theoretically possible but practically seems still impossible nowadays – in relation to problems with big number of moves.
In this respect, I can firmly say only the following: Michael Grushko has many compositions of this type – this is proof that he is very active in this field and his mastery has reached the level of virtuosity!
By the by, I can also say that many composers underestimate the fairy condition Republican Chess which do not occur often in practice. There is a large pool of new opportunities.
