 No.1322 Günther Weeth Germany original – 15.09.2018 Solution: (click to show/hide) white Kg3 Ba1c4 Rd8 Sg1 Pb3b4b5d3d4h3h6 black Kh5 Qh4 Rc3 Pc2d5g2g4g5g6 Bb1 -11 & #1    Proca Retractor     (12+10) Anti-Circe no animation for Defensive Retractors (JV) 1.Se8:Bc7[Sg1]!, B ~ -c7+ 2.Rd7-d8, Bd8 - ~+ 3.Rg7-d7 zz, Ba2-b1 4.e7-e8=S, Bb1-a2 5.e6-e7, Ba2-b1 (d7-d5? short mate as bPd7 is immobile, see black PP-captures) 6.e5-e6 (the position aimed at), Bb1-a2 (black pendulum start) 7.Bb2-a1, Ba2-b1 8.Ba1-b2, Bb1-a2 9.Bb2-a1, Ba2-b1 10.Ba1-b2 (legal, see en passant option, move rights due to FIDE vonvention), d7-d5 (forced) 11.Bf7-c4 – fw.1.Rg6:[Rh1]# Idea: Establishing a position where a white en passant option can be exploited. New facet: the thematic wP must first be created via unpromotion of a piece. Compare W. Dittmann, Die Schwalbe 2011, 2 nd prize (judge: Günther Weeth); there the critical position is created in an entirely different way. p.d.: tested with Pacemaker, but only with 2 opposite moves (G2). Due to the pendulum PM fails to indicate any solution. Adoptimg G3 was no use with my computer, PM seems to be lost in eternity! Any effort to paralize the bB by wS > a2, thus forcing h2-h3, Qh3-h4 ending up in a KK-mate on h4 is refuted by the fact that square h7 cannot be occupied by the rook being obliged to stop the bPg6.

Idea: Establishing a position where a white en passant option can be exploited. New facet: the thematic wP must first be created via unpromotion of a piece. Compare W. Dittmann, Die Schwalbe 2011, 2 nd prize (judge: Günther Weeth); there the critical position is created in an entirely different way. p.d.: tested with Pacemaker, but only with 2 opposite moves (G2). Due to the pendulum PM fails to indicate any solution. Adoptimg G3 was no use with my computer, PM seems to be lost in eternity!

(Author) No.1322.2 Günther Weeth Germany version to No.1322 – 30.12.2018 Solution: (click to show/hide) white Kg1 Qa2 Rb4h1 Bc4g5 Pb3b5d3e2f4h6 black Kh5 Qh3 Rc3 Bd1 Pc2d5g2g3g4 -11 & #1    Proca Retractor     (12+9) Anti-Circe no animation for Defensive Retractors (JV) 1.Rg7:Pg6[Rh1]! zz, Qh4-h3 2.Qa8-a2, Qh3-h4 3.Qe8-a8, Qh4-h3 4.e7-e8 = Q, Qh3-h4 5.e6-e7, Qh4-h3 (5....., d7-d5?, short mate as the bPd7 cannot uncapture according to the balance) 6.e5-e6 (the position aimed at), Qh3-h4 (starts a pendulum) 7.Ra4-b4, Qh4-h3 8.Rb4-a4, Qh3-h4 9.Ra4.b4, Qh4-h3 10.Rb4-a4 (legal, according to the FIDE convention concerning move rights White makes use of an en passant option), d7-d5 (forced) 11.Bf7-c4 – fw.1.Rg6:[Rh1]# This AntiCirce retractor can be regarded as being “logical”. The whole safeguarding play fulfils the sole purpose of the decoy of bPd5. The key move shows “relative purity of aim” as none of the three purposes fulfilled simultaneously is sufficient to define the safeguarding play on its own. Idea: Establishing a position where a white en passant option can be exploited. New fact: the thematic pawn must first be created via unpromotion of a piece. Compare W. Dittmann, Die Schwalbe 2011, 2nd prize (judge: Günther Weeth); there the critical position is created in an entirely different way. (Author)
