Career
Troitsky died of starvation during World World War II at the siege of Leningrad, where his notes were destroyed. 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" (Nunn 1995:265).
