I was at the receiving end of one of the most beautiful games of Chess at Wijk an Zee in 1999 --- where Kasparov sacrificed a Rook and then dragged out my King and chased it down the board winning with a long and stunning combination --- it is dubbed as "Kasparov's Immortal". However, I was to have my revenge later when I defeated Kasparov in the last game of his career before he retired.Who am I ?
