Alexey Alexeyevich Troitsky (Russian:Алексе́й Алексе́евич Тро́ицкий; March 14, 1866 – August 1942; alsoAlexei,Troitzky,Troitzki) was a Russian chess theoretician. He is widely considered to have been one of the greatestcomposers ofchess endgame studies.^[1] He is widely regarded as the founder of the modern art of composing chess studies (Seirawan 2003:91). Troitsky died ofstarvation duringWorld War II at thesiege of Leningrad. During the war, many of his notes got destroyed or lost so some of the latest chess problems he composed were never published.

One of his most famous works involves analyzing theendgame with two knights versus a pawn, seeTroitsky line.John Nunn analyzed this endgame with anendgame tablebase and stated that "the analysis of Troitsky ... is astonishingly accurate" (Nunn 1995:265).
