Not a good day for Nakamura. But it takes courage to play the Leningrad Dutch when your opponent (Kramnik) is expecting the Leningrad: here's Kramnik's analysis.
Tournament leader Shirov (+4) has five very tough games to play, and Nakamura (+2) is only half a point behind Kramnik and Carlsen (+3). It's quite possible that +4 will be enough to win: Nakamura can realistically still get there. +5 would be quite a tall order for Nakamura, but given his recent form and his remaining games, it's achievable.
