The New York Times has a good profile and interview with 17-year-old US Champion GM Hikaru Nakamura. (He also holds the even higher title of ChessNinja.com Black Belt newsletter contributor. So much for the Times research staff.)
As predicted, Hikaru is #43 on the latest rating list. (The 20 points he just gained in Foxwoods would raise him another 16 spots.) The article selects the brashest and boldest of his comments, and I'll do the same.
"The way I play is very unique," Mr. Nakamura said. "It's more or less that fearlessness. I'll play some of these really crazy moves that people are not going to be expecting. The way I play is not like most people. The moves are more computeresque. They're not the moves that most humans are going to play."
Of course Gata Kamsky is American, hit #3 on the list, and played Karpov for the FIDE world championship in 1996, but the point of his perhaps not being "American enough" for the American media and chess public is not invalid. (Not to mention that Karpov wasn't "world champion enough" in 1996.) Even Nakamura's Japanese name will probably cost him PR points in the lowest-common-denominator-seeking US media.
As for his style, few computers would take the risks Nakamura takes to win. He is the embodiment of the cliches "fortune favors the brave" and "good players make their own luck." It's well known that this generation of players (going back 10 years) are computer-trained to a large degree. They take material more readily and play without dogma. John Watson's acclaimed Modern Chess Strategy books elucidate this impression.
