Former world champion Garry Kasparov announced on Thursday that he will no longer play chess on a professional level.
But he will continue to play chess because "it is a lot of fun", the 41-year-old told a press conference in southern Spain.
"I will still play simultaneous games or blitz (lightning-fast) games but nothing else," he added.
Kasparov made the announcement after winning the Linares chess tournament against the current world number three, the Bulgarian Veselin Topalov.
