Solve the position | Circe
| 15 + 16 |
Show SolutionThe retro play is rather complicated and has a first introductory phase:
1. Qf1-g1 h5xRg4 2. Qe2-f1 h6-h5 3. Qd1-e2 Re2xQd2[Qd1] 4. Qd1-d2 Rd2-e2 5. h5xPg6[Pg7] f7xQg6[Qd1] 6. Se2xPf4[Pf7] h7-h6 7. Sg1-e2 Rd1xSd2[Sg1].
Now the black pawn from h7 must be brought back to b7. The missing black moves are waiting moves with Rd1.
8. Qh6 9. Qc6xPh6[Ph7] 10. Qa4-c6 11. Qa2-a4 R~-a1 12. Qb1-a2 13. Qd1-b1 g7xQh6[Qd1] 14. Qg6-h6 15. Qc6xPg6[Pg7] 16. Qa4-c6 17. Qa2-a4 18. Qb1-a2 19. Qd1-b1 20. Qe2-d1 Rd1-~ 21. Nb1-d2 Rd2-d1 22. Qd1-e2 f7xSg6 23. S~-g6 Rd1xQd2[Qd1] ... 26. Se8xPf6[Pf7] ... 30. Sb1 Rd1 31. Q~ Rd2 32. Qd1 Re2xQd2[Qd1] 33. Qd1 Rd2xSe2[Sb1] 34. Sg1 exSf6[Sg1] 35. Se8 Rd1xQd2[Qd1] 38. Sc7xPe6 41. Sb1 d7xSe6[Sb1] 45. Sb5xPd6[Pd7] 47. Sb1 Rd1 48. Q~ Rd2 49. Qd1 Re2xQd2[Qd1] 50. Qd1 Rd2xSe2[Sb1] 51. Sg1 c7xQd6[Qd1] 52. Qc6 Rd1xSd2[Sg1] 53. Qa4xPc6[c7] 56. Qd1 b7xQc6[Qd1] 57. a3xPb4[Pb7] etc.
