From the material imbalance this endgame should be drawn, as the advantage of the exchange is not decisive, but there may be special features of the position that give the stronger side the chance to play for a win.

    Russian Theorists in the Field of Chess Study Composing Have Always Considered the Following Article Hy the Famous Russian Composer A

    No. 11 January 1968 TROITZKY'S 1910 ARTICLE by J. Selman, Scheveningen (Holland) Introduction: Russian theorists in the field of chess study composing have always considered the following article hy the famous Russian composer A. A. Troitzky (1866-1942) to be the very base of to-day's "chess study theory". The article has, for example, often been cited and quoted by the well-known author A. O. Herbstman in his pioneer books, e.g. "Sjachmati Etjud v SSSR". It is therefore surprising that this article, written in 1910(!), has never been published in full outside Russia. Probably the reasons for this are that the article in question was published in the chess column of a rather obscure periodical, at least outside Russia, and that is has never been reprinted in the Russian periodicals specially dedicated to chess. Fifty-seven years have gone by since Troitzky wrote the article and Znosko-Borowski had it published in his new chess column in the periodical "Niva". Therefore it goes without saying that the article has to be read and evaluated in the light of chess history and must mainly be considered as an interesting "museum piece". However, many observations made by Troitzky so long ago are still valid, and even of importance, for the chess study world to-day. For more than 30 years I have tried from time to time to obtain a copy of Troitzky's article, but all my efforts in this direction were in vain, so that I finally came to believe that it was classified in Moscow as a "state secret" and was guarded as such! However, last year - as a result of the co-operation and help of the Grandmasters Prof.
