Retract: -1. Ke1xPf2 f3-f2 -2. Ke2xPd2 Ke7-f6 -3. Ke1-e2 d3-d2 -4. Kd5xQe5! Kd8-e7 -5. Rc7-c1 and

Forward: 1. Rd7#

Tries: -4. Ke5xQf6? Qf8-f6!; -2. Ke2xRf1? Ke7-f6 -3. Re1-e2 Bh8-g7! and Rf1 guards a1.

Cook: -1. Ra1-c1! and lots of variations, all ending in mate after 4 retractions, e.g. -1. .. Bg4-h5 -2. Ra1xQc1 Q~-c1 -3. Rd5xPd2 d3-d2 -4. Kf8xR/Se8 and 1. Kf7#

 

Correction:

R234cc - Wolfgang Dittmann

[8/6b1/3N1k2/7b/4p3/8/2R5/4K3]

3+4. Retract 5 moves; then #1 (Proca Retractor, Anticirce)

[8/6b1/3N1k2/7b/4p3/8/2R5/4K3]

Solution see above. -1. Rc1-c2? doesn't work because of -1. .. Bf8-g7! -2.
Ra1-c1 Bf8xBe7!
