Thessaloniki Grand Prix Round 8

Gata Kamsky grabbed the sole lead of the Thessaloniki Grand Prix by beating his compatriot Hikaru Nakamura in a thrilling eighth round.
The all-American clash was virtually decided as early as move 15 when Nakamura blundered with Qa3?? The game continued until move 50, but there was no miracle escape from Nakamura this time. He tweeted, "When you start missing 1-2 move combinations in every game, it is time to take a long break from chess".

There was no shortage of excitement in the eighth round, even by the high standards set by the Thessaloniki Grand Prix so far, with only one game ending as a draw! Fabiano Caruana drew with the black pieces against Alexander Grischuk to drop half a point behind the leader Kamsky.
Joining Caruana on 5½ points is Leinier Dominguez, who thrashed Alexander Morozevich to stay in close contention at the top of the standings.
Friday is the last rest day, so round nine is on Saturday.
