New Delhi: Indian Grandmaster Viswanathan Anand posted his second win on the trot, defeating Bulgarian Veselin Topalov in the Classical section to take the lead at the Norway Chess tournament in Stavanger. The 52-year-old Anand trumped his opponent in 36 moves in the battle of the veterans to make it two out of two after the second round late on Wednesday. The five-time World champion is in the sole lead with six points. He had started the Classical event with a win over France's Maxime Vachier-Lagrave following a fourth place finish in the Blitz event. American Wesley So, who won the Blitz event ahead of the classical section, outwitted World No. 1 Magnus Carlsen in the Armageddon (Sudden death game) to lie in second spot behind Anand after their regular game ended in a 38-move draw.
