The Hungarian grandmaster first defeated former World Championship finalist Boris Gelfand of Israel and then Russia’s Nikita Vityugov, ranked 25th in the world. In the round of 32, he was up against former world champion Ruslan Ponomaryov, the two-time Olympic team champion from Ukraine, whom he defeated in the first game on Wednesday. In Thursday’s rematch, a draw in the dark was enough for him to reach the eight-finals.
