When Nakamura bursted into the scene he had one huge weakness and that were his openings. Over the years he made the transition and incorporated freerolls and forced draws into his repertoire. Just look up his win in the English against Karjakin and you know what I am talking about. In the following game Naka is willing to repeat an old line that dates back to the Kortchnoi-Karpov match in 1978. It looks like Karjakin smelled a rat and went for the forced draw.
