Plaskett's Puzzle

This is a chess puzzle I found while browsing chess videos on youtube and it is without a doubt the one of the coolest positions I have ever seen.  Apperently it was presented at Brussels 1987 (Kasparov and Ljubomir won, Karpov came in second) and nobody could solve it (not even Kasparov or Karpov) except for Mikhail Tal, who examined the position for a few minutes, went on a walk, then came back with the solution.  Here it is, be sure to click on move list after viewing the solution to see the full layout of the variations as well as additional comments.
