 | | 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 |

 | | Chessical: From the above article, it seems that Grigoriev's health and life was destroyed by imprisonment by the Soviet secret police during a purge of 1937. "In early October 1937, Grigoriev returned from a trip to the Far East and Siberia, where he gave lectures and played. The NKVD militia on the train arrested him". "Grigoriev was frail; he "lost consciousness immediately after the use of force, and his throat began to constantly bleed. After an interrogation, the interrogators had to wash down the room". "An unexpected illness (which no surprise after living in the basement of the NKVD! - Auth. ) confined him to bed. Severe complications required immediate surgery. The patient was severely weakened (officially Grigoriev had an unsuccessful operation on his thyroid gland. - Auth. ), and he developed lung cancer. |

| Aug-14-12 | | brankat: A strong master and a brilliant end game studies composer. An excerpt from the article <whiteshark> provided the link to: "Nikolai Dmitriyevich Grigoriev, who thorough investigations of both the artistic and the practical aspects of pawn endgames form the basis of the modern theory of these endgames. In The Oxford Companion to Chess (by D. Hooper and K. Whyld, Oxford University Press 1984) we find that Grigoriev, born in 1895, was also a very strong tournament player, winning the Moscow Championship four times during the 1920's and coming fifth in the 1920 USSR Championship. But it is in endgame composition and analysis that Grigoriev made his most enduring contributions, and in his specialty, the pure pawn endgame, he had no equal." R.I.P. master Grigoriev. |

Then both players will make a queen, White first, but Black with check. The result will only be a draw. If he starts with his f-pawn, 1. f4, he threatens to queen with check at f8. That will force the black king to come back, 1 ... Kb4, in order to catch up with the pawn. This establishes the basic formula. When White moves his h-pawn, Black advances his d-pawn, and when White moves his f-pawn, Black comes back with his king. Astutely jockeying both pawns enables White to win.> 1. f4 Kb4 2. h4 d5 3. f5 Kc5 4. h5 d4 5. f6 Kd6 6. h6 d3 7. f7 Ke7 8. h7 d2 9. f8=Q+ <This is what it's all about, sacrificing the f-pawn so that the h-pawn can queen with check:> 9 ...

| Feb-08-17 | | TheNige: For the nonce, there is an online library that includes a large collection of Grigoriev's games and studies (in Russian). Once you extract the file, you can read it using, for example, a program like Sumatra.pdf or such, as it is a djv-type of file. The book is something like "Analysis, Theoretical Studies, and Selected Games." See http://publ.lib.ru/ARCHIVES/G/GRIGO... |

| Feb-08-17 | | TheNige: "Nikolay Dmitrievich Grigoriev
Number of games in database: 56
Years covered: 1910 to 1945"
Grigoriev passed away in 1938. An editorial correction should be made in his biographical entry. |
