No. 118 , July 1996 - SOLUTIONS

3569 - Leonid Borodatov

All 11 missing Bl. units have been captured by the Wh. Pawns. The wPd5 is from a2 and the wPg7 from b2.

The wRh1 has been captured in the SE corner. So that Bl. other two captures are e7xf6 & h7xg6. The bPg7 was captured on its home square through wPf6xg7. The bPa7 promoted on a1 for balance.

Last move was -1. c7-c5 because retracting e7xf6 would not allow reconducting the bKB on f8.

Mate in 4 is with 1. d5xe6 ep 2. c7 3. c8=N 4. Ne7# (1. Nd7? Kh7!).


3570 - Mario Velucchi

Last move was made by White's Ra1 or Kh1 so that O-O-O is broken.
h3# is with 1. ba4 ab3 2. Kxb3 Kd2 3. Kb4 Rb1#.


3571 - Thierry Le Gleuher

Author's intention is 1. h4 Nc6 2. Rh3 Nd4 3. Rc3 Nxe2 4. Rc6 bxc6 5. a4 Ba6 6. a5 Bd3 7. a6 Be4 8. d3 Qb8 9. Be3 Qb5 10. Bb6 axb6 11. a7 O-O-O 12. a8=B Re8 13. Bb7+ Kd8 14. Ba6 Qh5 15. Bc4 g5 16. Be6 Bg7 17. Bg4 Be5 18. Bf3 Bh2 19. g3 f5 20. Bh1 Bxh1 with a far-fetched Frolkin capture of a promoted Bishop.
