So, Wesley 1-0 Troff, Kayden
Wesley So kam nach seinem Sieg gegen Kamsky in Runde zehn zu einem weiteren Sieg. Troff zeigte in der Vorbereitung Schwächen und verlor in einer Variante des Grünfeld-Inders früh einen Bauern. Kompensation erhielt er dafür nicht und So gewann ohne große Mühe.

Naroditsky, Daniel ½-½ Kamsky, Gata
Naroditsky stand gegen Kamsky etwas besser, aber zu mehr als Remis reichte dieser Vorteil nicht.

Kamsky ging als Titelverteidiger als Rennen, aber landete am Ende auf dem geteilten fünften Platz.

Shankland, Samuel ½-½ Akobian, Varuzhan
Shanklands gute Eröffnungsvorbereitung verhalf ihm zu einer guten Stellung und einem besseren Turmendspiel, das Akobian allerdings ohne große Probleme halten konnte.

Sevian, Sam 1-0 Holt, Conrad
Eine aufregende Partie! Sevian ließ sich auf Holts Lieblingsvariante im Franzosen ein, aber verpasste die Möglichkeit 27.Sf5! mit Gewinnstellung. Danach war der weiße Angriff zu langsam und Schwarz übernahm die Initiative und setzte seine Hoffnungen in seinen b-Freibauern. Tatsächlich erreichte Holt ein vorteilhaftes Endspiel, das aber nicht einfach zu gewinnen war. Auf der Suche nach einem Sieg dachte Holt zu lange nach und verlor in Gewinnstellung nach Zeit.

Nakamura, Hikaru 1-0 Onischuk, Alexander

Hikaru Nakamura gewann das Turnier verdient und blieb als einziger Spieler ohne Niederlage

The rook just doesn't do enough here.} (23... g6 {followed by Rfb8 is still very drawish.}) 24. g3 g6 25. b4 {White's extra pawn isn't so shabby anymore.} Nd3 26. Nc6 Re2 27.

Kh1 Nf2+ 30. Kg2 Nd1+ 31. Nxe2 {An abrupt end to the tournament. Onischuk got an easily drawn position, which is perhaps not what he was searching for, but all it takes is a couple inaccuracies to make life difficult. Congrats to Hikaru, who while not playing up to his standards, played well enough to win the event.} 1-0

Gareev, Timur 0-1 Robson, Ray
Gareev spielte mit Weiß, aber erlitt bereits in der Eröffnung Schiffbruch und stand nach 13 Zügen auf Verlust. Robson hatte keine Probleme, seinen Vorteil in einen ganzen Punkt zu verwandeln.

Zweiter Platz für Ray Robson

Ni, Viktorija 1-0 Virkud, Apurva
Ni spielte einen langsamen Reti-Aufbau, um dann am Königsflügel anzugreifen. Virkud gelang es nicht, ausreichend Gegenspiel am Damenflügel zu bekommen und musste zusehen, wie ihr König dem weißen Angriff zum Opfer fiel.

Apurva Virkud kam per Freiplatz ins Turnier, aber hatte Schwierigkeiten sich in dem starken Feld zu behaupten und wurde mit 3,5 aus 11 Zehnte.

Paikidze, Nazi ½-½ Foisor, Sabina
Mit einem Sieg und etwas Glück - nämlich bei einer Niederlage von Krush gegen Nemcova - hätte Paikidze gegen Krush und Nemcova in einem Dreierstichkampf um den Titel spielen können, doch Paikidze verzichtete darauf, mit der Brechstange auf Gewinn zu spielen. So kam Sabina Foisor in einer slawischen Abtauschvariante ohne Probleme zu einem Remis und Nazi Paikidze landete bei ihrer ersten US-Meisterschaft auf dem geteilten zweiten bis dritten Platz.

Krush, Irina ½-½ Nemcova, Katerina
Irina Krush reichte ein Remis zum Titelgewinn und so tauschte sie von Beginn an munter Figuren, was ihr schließlich zu einem leicht besseren Endspiel, einem mühelosen Remis und ihrem siebten Titelgewinn bei US-Meisterschaften verhalf.

Irina Krush

Goletiani, Rusudan ½-½ Yu, Jennifer
Goletiani hatte Glück, das ihr schlechtes Spiel in der Eröffnung, das Schwarz starken Angriff gab, von Yu nicht energischer bestraft wurde. Doch Yu unterlief ein Versehen und Weiß erhielt dank ihrer guten Schwerfiguren und ihrem starken Läufer auf b2 ein aussichtsreiches Endspiel. Doch Goletiani gab das Kompliment zurück und am Ende wurde die Partie Remis.

Wang, Annie 1-0 Melekhina, Alisa
In einem komplizierten Wolga-Gambit stellte Melekhina eine Figur ein und verlor so die Partie.

Alisa Melekhina, die bei der Mannschaftsweltmeisterschaft der Frauen, die in wenigen Tagen in China beginnt,
für die USA spielen wird, war bei der US-Meisterschaft noch nicht in Form.
