The position is released by quickly uncapturing a wN on the b-file, which is then brought to f1 to screen. Then wBc2 may be extracted and later a wR, followed by retracting wB to f1 and opening the cage by uncapturing e2xBd3. The whole thing is rather complicated (both wR's must go via the queen side), and all available tempo moves by bP's are used. Start the forward play from the following position.

Play forward: 1. . Nb2 2. Kc2 Be4 3. Kc1 Bd3 4. exd3 h6 5. Be2 h5 6. Bf3 Kf1 7. Be4 Ke1 8. Kc2 Kf1 9. Re5 Ke1 10. Nf3 Ke2 11. Rc1 g6 12. Ne1 Kf1 13. Bf3 Kg1 14. Be2 Kh1 15. Bf1 Kg1 16. Nf3 Kh1 17. Nd4 Kg1 18. Ree1 Kh1 19. Red1 Kg1 20. Nf3 Kh1 21. Ne1 Kg1 22. Be2 Kh1 23. Bf3 Kg1 24. Be4 Kf1 25. Nf3 Ke2 26. Rh1 g5 27. Rcg1 f6 28. Ne5 f5 29. Ng4 f4 30. Nd3 d6 31. Nf1 Ke1 32. Kc1 Ke2 33. Bf3 Ke1 34. Bd1

(a) e5 35. Bc2 Ke2 36. Bg3 Ke1 37. Ne3 Ke2. Now wN can only reach the b-file in exactly two moves: 38. Nd5 h4 39. Nb6 axb6 40. Rf1 b5 41.Rfg1, so Black has the move and wins by e.g. 41. .. cxd2#.

(b) d5 35. Bc2 Ke2 36. Bg3 Ke1 37. Ne3 Ke2 38. Nf5 h4 39. Nd6 a6 40. Nb5 ab5 , so White has the move and wins by 41. Re1#.
