599 - A. Kornilov and A. Frolkine
Europe Echecs 430, 01/1995

Last move is Qf5xh5+. The triple d pawns require 2 captures. The missing a2 and a7 pawns could not play a role in these captures (unless there was an additional capture). Then the color of all K-side pawns is determined because it is impossible to account for two more captures. Thus WPh2, WPg3, WPf4, WPe4 are White; BPh3, BPg7, BPf7, BPe7 are Black. This entails: WKg4, BKh6, WQh5, WRh4, BRh7, WNe5, WNf6, WBe6, BBf8, WPc7, WPd7, and then WPd5, BPd6, BPc6.

Now the last moves are necessarily: -1. Qf5xBh5+ Bg6-h5+ -2. Nh5xBf6+ Bg5-f6. The B promotions require WPb7: the BPs originally on a7 and b7 promoted into Ba1 and Bb1 while the WPs avoided them with Pb2-b6xc7 and Pa2-xb-b7. Thus we complete the coloring with BQg8, WRh8, BBe8, WBd8.
