No.444 by Michael Grushko & Semion Shifrin – A very nice “Tanagra” problem in aristocratic form! (JV)


Definitions:

Take & Make: Having captured, a unit must immediately, as part of its move, play a non-capturing move in imitation of the captured unit from the capture-square. If no such move is available, the capture is illegal. Promotion by capture occurs only when a pawn arrives on the promotion rank as the result of a take&make move. Checks are as in normal chess: after the notional capture of the checked K, the checking unit does not move away from the King’s square.

Circe Parrain: After a capture, the captured piece is reborn only after another piece of its own side has moved. The line between capturing square and rebirth square is parallel with and of same direction and length as the move of this other piece. Pawns can be reborn on 1st and 8th rank. From their own base rank, they may move one-step; if reborn on the promotion rank, the Pawn at once promotes, the promotion piece being determined by the Pawn side.

      Thank you, Janos, for your interest in our problem.

      You are right, that with such material and conditions it’s possible to get more solutions.

      But we made an effort to get maximal richness for each move, and obligatory agreement ,

      that each mate would be used with fairy conditions.

      For example, we had a version:

      W: Se2 , Sf1 B: Kf2 , Re3 , Bh5

      H#3 4 solutions

      1.Re3*e2-g1 Sf1-h2[+wSg3] 2.Kf2*g3-h1 Sh2-g4[+wSf5] 3.Bh5*g4-h2 Sf5-e3[+wSf2] #
      1.Re3*e2-g3 Sf1*g3-g4[+wSf5] + 2.Bh5*g4-e3[+bRd1] Sf5*e3-f4[+wSg3] 3.Kf2-e1[+bBd2] Sf4-d3 #
      1.Bh5*e2-g3 Sf1*e3-f3[+wSe4] + 2.Kf2*f3-h4[+bRg5] Se4-f2[+wSg1] 3.Rg5-h5 Sg1-f3 #
      1.Bh5-f3 Sf1-d2 2.Kf2*e2-c1 Sd2*f3-d1[+wSe1] 3.Re3*e1-c2[+bBd2] Sd1-c3[+wSd3] #

      But we rejected it, because the mates in the second and third variants didn’t meet our criterions .

    Thank you, Semion and Michael, for the clear presentation of your intention! In your very nice original the third mate is more beautiful for me, than the other two, because the reborn wS gives the checkmate. See the next version with two similar solutions:
    White Sd6 Sa5 (2)
    Black Qd8 Bc5 Ka4 (3)
