This superb result earned him a place on the Soviet team he won both his games played on board ten, helping the Soviet team to victory in the famous 1945 USSR vs. Theretofore seen as a promising but essentially unproven young player, one of dozens in the deep Soviet vanguard, he raised his playing level dramatically to place third in the 1945 USSR Championship. Bronstein moved to Moscow as the war wound up. With the tide turning towards an eventual Soviet war victory over the Nazi invaders, Bronstein was able to once again play some competitive chess, and he defeated Soviet champion Mikhail Botvinnik at the 1944 USSR Championship, which was his own first appearance at the Soviet top-standard event.

This belief could have explained the imprisonment of Bronstein's father. The rumor that Bronstein was related to the disgraced former Soviet Communist leader Leon Trotsky (whose real family name was Bronstein), was treated as unconfirmed, but doubtful, by Bronstein in his book The Sorcerer's Apprentice (1995). Also during the war, his father, Johonon, was unfairly imprisoned for several years in the Gulag and was detained without substantial evidence of committing any crimes, it was later revealed. Judged unfit for military service, Bronstein spent the war performing various jobs this included doing some reconstruction of war-damaged buildings and other clerical/labor type jobs.

He later went on to marry Boleslavsky's daughter, Tatiana, in 1984.ДЄfter completing high school in spring 1941, his plans to study mathematics at Kiev University were interrupted by the spread of World War II throughout eastern Europe in the early 1940s. He finished second in the Kiev Championship when he was only 15, and achieved the Soviet Master title at age 16 for his second-place result in the 1940 Ukrainian Chess Championship, behind Isaac Boleslavsky, with whom he became close friends both on and off the chessboard. As a youth in Kiev, he was trained by the renowned International Master Alexander Konstantinopolsky. Growing up in a poor family, he learned chess at age six from his grandfather.
