The much-awaited World Championship Chess match begins at Chennai this afternoon as a stern test awaits for Indian chess wizard Viswanathan Anand in quest for a sixth title. Anand, the undisputed world champion since 2007, faces a strong challenge from the 22-year-old Norwegian sensation Magnus Carlsen in one of the most awaited World Chess Championship matches in recent history. The match between five-time champion Anand and world number one Carlsen is comparable to the historic clash between Bobby Fischer and Boris Spasky way back in 1972.
