Solution: 



  • Try: 1.Qb6+? Not forced is 1... Qxb6#?? 1... Ka8? is shorter 2.Qe6 4.Kc7 5.Qc8+ etc, but try is defeated by ... Kc8! and white loses control.

    Try: 1.Qd7+? 1... Ka6?? 3.Qb6+ 1... Ka8 is shorter 2.Qe6 4.Kc7 5.Qc8+ etc, but try is defeated by 1... Kb8! , which needs one move longer: 2.Qe6 4.Kd7 6.Qc8+ Ka7 7.Kc7 8.Qb8+ etc.

    Solution: 1.Kd6 2.Kd7 3.Qd6 4.Qc7+ Ka8 (if 4... Ka6 5.Kc8 6.Qb7 etc or 5.Qb8 6.Kc7 7.Qb7) 5.Qc8+ Ka7 6.Kc7 7.Qb8+ Ka6 8.Qb7+ Ka5 9.Qc6 10.Qd6 12.Kc5 13.Qb8 14.Qb4+ Ka6 15.Qb6+ Qxb6#

    After 7... Ka6 it is premature to try to return to c5, e.g. 9.Qe6?? 11.Kc5 12.Qb6+, since Qe6 is check.

Solution: 

1.g7 2.Bg6 3.g8=R 4.Rf8 5.Rf5 6.Be8 7.Bb5 8.c6=

Back-Home is a new fairy condition invented by the T142's author, with the following definition:
  1. If a piece can legally move to the square it occupied in the diagram position, it must move to this back-home square.
  2. Back-home moves are prevalent to the virtual capture of the opponent King by any piece, i.e. checks are fairy.
  3. If more back-home moves are legal, the side-on-move chooses which one to play.
  4. The back-home square of a Pawn which is promoted during the solution is the initial diagram square of this Pawn.

  • "The problem explores the subtle difference between consequent series-movers and ordinary series-movers with fairy condition Amnésie. Here everything revolves around the fact that pawn's double-step is illegal if the opponent can capture it en passant. Therefore, the final position in a) is mate, since Black's defence d7-d5 is illegal. Let us turn to phase b). How is 3.d7-d5 + now legal? Because of Amnésie, White cannot capture d-pawn en passant on his following move (unless he can prove that the previous move was indeed the double-step; in this case, the previous move could as well be bLa8-c6, and thus there is no proof), and therefore 3.d7-d5 + is not forbidden! This is also the reason why the solution from a) doesn't work anymore - Black now could defend with d7-d5." (Author)

  • Take & Make Chess: Upon capturing a unit X, a unit Y (K included) must continue from the square of capturing to make a single non-capturing move with the movement of X. If such a move does not exist, X cannot be captured by Y. The square of capturing is the square occupied by Y when the capture takes place (important for e.p. captures). Pawns must neither be placed on nor played to their first rank by the take&make condition. A pawn is promoted if and only if the final square of its move is on the 8th rank. Checks are as in orthodox chess.

  • After careful preparation, the King and Bishop nudge the Queen into the target square (h3). The wK returns to its diagram square after a long journey. Interesting roles for both white Bishops as well.
  • aser-s*z22 means "anti-parry-series self-autocheckzug in 22": white plays the series and is permitted to auto-check; when anti-parrying, black will resist white's plan; white's 22nd move forces black to put white in autocheckzug. (*)

  • The key moves are 4, 12 and 13 - an interesting "evacuation" cycle:
    Bishop (A) - Pawn (B),
    Pawn (B) - King (C,
    King (C) - Bishop (A).
  • Reversible Promotion is a recent condition invented by Almiro Zarur - a promoted (white / black) piece turns back to a (white / black) pawn when it moves to the second (if white) or seventh rank (if black).

  • Beautiful APS composed by the Anti-Parry Series' inventor!
  • The similarities between APS and Vogtländer should be noted. In fact, the composition was partially tested by using the Vogtländer condition and the pser-a=>b stipulation, excluding only the last half-move.
