Karpov – Kasparov1987
The Grünfeld's central argument, in a world championship game between the opening's greatest defender and its most patient opponent. White takes the whole centre, Black hits it with …c5 and pieces, and when Karpov sacrifices a bishop on f7 to keep it, Kasparov's queenside pawns and the bishop pair do the rest. Fifty moves.
