Reliving the 'Immortal' game

Some chess games are dubbed ‘Immortal’ for the sheer beauty and creativity they offer to the enthusiasts and followers.

On 13th April, it seems appropriate to feature a game dubbed ‘Immortal” by many experts as it features one of the strongest World champions of all times, the 13th World Champion Gary Kasparov who was born on this day and celebrates his 51st birthday. Interestingly there are more than 200 annotations of this game available.
