When Sofia was announced as the winning bidder for the 2010 World Chess Championship match, many believed that the titleholder Viswanathan Anand would be at a serious disadvantage competing on his challenger Veselin Topalov’s home territory.

Anand did not have much choice. Sofia’s was the only serious bid and the prize fund of €2 million Euros (about $A3 million) was the highest offered for a chess match since the early 1990s.
