| Benzol: A Study by Grigoriev from 1917
click for larger viewThe White Queen and King cannot similtaneously attack the a6 square, and assist the advance of the a-pawn. Since the pawn is a rook's pawn White can't transpose into a pawn ending to win. The Black Rook has two safe squares, a6 and d6. It also can't be forced off the sixth rank so the White King can't break through to attack the Black pawn. A possible variation :
1. e4+  a7
2.f3  a6
3.f5 b7 Black must prevent c8
4.f8 d6
and White cannot improve his position. Therefore 1/2-1/2. This ending had practical application in two games :
Averbakh vs Bondarevsky, 1948
and
Flohr vs Lilienthal, 1950 |

| Marmot PFL: Did Russian sources ever reveal how he died? Seems it was about the same time as Krylenko. |
