Alexey Troitsky

Template:Short description Template:Use dmy dates Template:Template other Alexey Alexeyevich Troitsky (Template:Langx; March 14, 1866 – August 1942; also Alexei, Troitzky, Troitzki) was a Russian chess theoretician. He is widely considered to have been one of the greatest composers of chess endgame studies. He is widely regarded as the founder of the modern art of composing chess studies Template:Harvcol. Troitsky died of starvation during World War II at the siege 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 the endgame with two knights versus a pawn, see Troitsky line. John Nunn analyzed this endgame with an endgame tablebase and stated that "the analysis of Troitsky ... is astonishingly accurate" Template:Harvcol.
