"This is a chess problem steeped in legend. Imagine if you will, the year is 1987; the location, Brussels. Some of the strongest players in the world, including recently crowned world champion Kasparov, are participating in one of the biggest tournaments of the year. Even the world champ must work very hard just to keep the pace with Karpov and Ljubojevic, both on top of their games. Also playing are famous grandmasters such as Jan Timman, Viktor Korchnoi, Bent Larsen, Nigel Short, and the living legend Mikhail Tal. Darting in and out of the press room are all manner of GMs. Suddenly, in pops Jim Plaskett, a young and intense British grandmaster. In between telling jokes and talking politics, he sets up a most intriguing position. "White to play and win" he pronounces, then departs, leaving the position as a parting gift. Or perhaps one should say a parting shot! For several hours, chess fans and GMs alike try their hand at unraveling Plaskett's mysterious puzzle. While some of them apparently make progress in the analysis, no one can completely work out the complexities of this deceptively deep position. Even the computers choke on it. The tournament was a tie between Ljubojevic and Kasparov (both with 8.5/11), but Misha proved his genius in a way that the other GMs could not. After struggling with the puzzle for a few minutes, Tal left the playing hall to take a walk. An hour later, after some fresh air, the Wizard from Riga popped back in and immediately played the correct solution on the board, a variation so subtle and beautiful that it stunned all who witnessed it."
