9/15/2013 – It seemed for a moment that a repeat of the Candidate's tournament would occur. Nakamura was against the ropes against Kamsky but he was able to salvage an almost miraculous draw. Aronian with black outplayed Carlsen, played on in an equal endgame, and then saw his position deteriorate move by move until a blunder sealed his fate in an already bad position. Carlsen wins another tournament. Last round report.

The Sinquefield Cup is taking place from September 9th to September 15th at the Chess Club and Scholastic Center of Saint Louis. The tournament brings together the top two players in the world as well as the top two Americans in a double round robin. The time control is the standard FIDE 90 minutes for 40 moves plus thirty minutes at move 40 with 30 second increment throughout. Sofia rules apply, which means none of the games can be drawn before move 30 - with certain exceptions.

The man: Rex Sinquefield. Thanks to him the Sinquefield Cup, the Chess Club and Scholastic Center of Saint Louis, the World Hall of Fame not only exist but are top-tier class. Not to mention the over 500 schools the chess club reaches out to to popularize and teach chess.

Round six

The Sinquefield Cup has finished in a very unexpected way. Kamsky had the chance to upset Nakamura after the latter took too many early risks, but eventually Kamsky was unable to convert. His inaccuracies near the end of the game still gave him a small edge due to the weakend position of Black's king, but a combination of not being in shape and probably wanting to get the tournament over with influenced his decision to take a draw by perpetual check. This wasn't so bad for Nakamura as at this point Carlsen was significantly worse in his game.

Kamsky was friendly from start to finish, despite the less than stellar result

Nakamura's opening was risky and you could argue that he got the unbalanced position he wanted, but he soon found himself in trouble

Kamsky's 2625 performance is well below his rating, but he hopes to bounce back in future tournaments

When asked about his play in Saint Louis the Norwegian mentioned that he was overall pleased and that he was in good form. Despite being slightly worse at the beginning of the game, Carlsen fought back and even refused a draw offer when he sensed that he had chances to be better, despite the fact that a draw would've clinched first place.
