The Retrograde Analysis Corner
No. 108, October 2002 - SOLUTIONS
8870 - Per Grevlund
Intended retroplay: -1.Ke7 Kd7 -2.d5xPep c7, but cooked by -1.Qe7.
Correction: replace wQd8 with wRd8.
8871 - Henrik Juel
-1.Kg7-g8+ Bb4-g8+, 1.Kc3 Be5#. Not -1.Kg7xSg8? since all captures were made by pawns, or -1.g7xh8=B? since the 2 extra captures (in addition to the 8 captures necessary to promote 16 pawns) created a surplus of white bishops on light squares.
8872 - Ivan & Gligor Denkovski
1.c4 e6 2.Qc2 Bd6 3.Qxh7 Bxh2 4.Qxh2 Rh3 5.Sc3 Rxc3 6.f3 Rxc1+ 7.Kf2 Rxf1+ 8.Kg3 Rxg1 9.Kg4 Rxh1 10.Qg1 Rh8 11.Qd1 Sh6 12.Kh5 a5 13.g4 a4.
