Victor Korchnoi is still alive though he is in his eighties now and I think its true to say he is the longest lasting top player to ever play at the highest level as he has played in some strong tournaments since 1950 although now his play has declined from its previous heights. He came within 1 game of winning the World Championship but he never made it, but is still recognised as a great player. Here he plays Miroslav Filip a czechoslovakian player and demolishes him with a brilliant sacrifice.

Holes in chess positions are places which can be occupied with near impunity by one side against the will of the other and causing a strategically won game. Here the move e5 allows the Knight to occupy d5, the hole being on e5.

40.Rb6 Nd4 41.Rc5 The position is hopeless- two pawns down and posibly losing d5 as well which was Miroslavs last hope here. 1-0
