Lösung

There is a lot of time pressure. The position will unlock once white can retract e2xd3, and for this, the white bishop needs to go to f1 (and thus a white rook has to go to h1 too)

Retro play is: 1. Be5-h8 Pe4-e3 2. Bg3-e5 Pe5-e4 3. Qb1-c1 Pe6-e5 4. Rc1-f1 Pe7-e6 5. Bb8xPg3 Ph4xNg3 6. Nf1-g3 Ke1-e2 7. Bd1-c2 Ph5-h4 8. Rc2-c1 Ph6-h5 9. Nc1-a2 Ph7-h6 10. Bg4-d1 Kd1-e1 11. Bc8-g4 Ke1-d1 12. Qa2-b1 Kd1-e1 13. Ne2-c1 Ke1-d1 14. Ng3-e2 Ke2-e1 15. Ne4xPg3 Kd1-e2 16. Ng5-e4 Ke2-d1 17. Nf3-g5 Kd1-e2 18. Ne1-f3 Ke2-d1 19. Ne3-f1 Kd1-e2 20. Nd5-e3 Ke2-d1 21. Nf3-e1 Pg4-g3 22. Rc1-c2 Pg5-g4 23. Rf1-c1 Kd1-e2 24. Ne1-f3 Kc1-d1 25. Ne3-d5 Pg6-g5 26. Nd1-e3 Kc2-c1 27. Nf3-e1 Kc1-c2, the WRs leave the first rank, the WK exits, the WKR returns, the WKB returns, then the WKP uncaptures to e2 and the positions unwinds.
