(27.01.2013) A super problem with complicated combination of four fairy conditions by Michael Grushko (Israel)!

1. Se5xc4=bB(+wSg8) Sg4xe3=wB(+bSg1) 2.Be3xg1=bR(+wSb8) Rg1xg8=wQ(+bSb1) 3.Sb8-a6=P Bc4xa6=wR(+bPa2) 4.Ra6-a3=B Sb1xa3=wB(+bBc1) 5.Qg8-g1=R Bc1xa3=wR(+bBc1) 6.Ra3xa2=bQ(+wPa7) Qa2xa7=wQ(+bPa2) 7.Qa7-f2=R(+bKd1)+ Bc1-e3=S(+wKf1)#

   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.

   Einstein Chess: every time a piece moves (without capturing), it "loses energy" and transforms itself ("is demoted") into a smaller unit, one step down the ladder from Queen to Rook to Bishop to Knight to Pawn. Every time a piece captures, it gains energy and   transforms itself ("is promoted") into the next bigger unit. Kings do not transform. A capturing Queen-move or a non-capturing   Pawn-move does not lead to any transformation.There are no promotions. So that you can have pawns on the 8-th rank   (where they are stuck). You can also have pawns on the 1st-rank (after a non-capturing Knight move): these pawns can make a single, double  or triple step forward. After a double or triple step,   they can be captured en-passant by an enemy pawn on the 3rd or 4th rank.   After a triple step, en-passant capture can take place on two different   squares!

   Andernach Chess: all pieces change color (and the side) after they capture. The rule does not apply to Kings. A pawn capturing on the 8th rank is 1st promoted, and then changes color

   Circe Turncoats: a unit (not King) when captured returns to its game array square with opposite color as part of the capturing move.
