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.
