Troff, Kayden 0-1 Sevian, Samuel
Eine wechselhafte Partie. Troff spielte in der Eröffnung zurückhaltend und erhielt dementsprechend wenig Chancen. Das änderte sich erst, als Sevian beschloss, seinen Bauern auf d4 seinem Schicksal zu überlassen. Troff übernahm die Initiative. Wenig später brachte er ein aussichtsreiches Qualitätsopfer, für das er mehr als genug Kompensation bekam.

Doch dann kam Troff vom rechten Weg ab. Sevian konnte seine Stellung wieder konsolidieren und übernahm seinerseits die Initiative. Im Endspiel unterliefen Troff dann noch weitere Fehler und Sevian konnte schließlich gewinnen.

Nakamura, Hikaru ½-½ Shankland, Samuel L
Eine strategisch interessante Partie in der Caro-Kann-Vorstoßvariante, die zu einem Endspiel führte, in dem Shankland vielleicht einen Hauch besser stand. Doch Shankland verzichtete auch Gewinnversuche und so endete die Partie mit Remis.

Gareev, Timur ½-½ Naroditsky, Daniel
Eine Partie, in der nichts geschah.

Daniel Nadoritsky kam ohne Probleme zu einem Remis

Robson, Ray 1-0 So, Wesley

Melekhina, Alisa 0-1 Ni, Viktorija
Mit einem kühnen, doch vielleicht objektiv nicht ganz korrekten Bauernopfer riss Ni die Initiative an sich bold pawn sacrifice! Irgendwann konnte Melekhina die Drohungen der Schwarzen nicht parieren und Ni gewann.

Alisa Melekhina

Viktorija Nis zweiter Sieg in Folge

Abrahamyan, Tatev 1-0 Foisor, Sabina
Abrahamyan gewann, weil sie die Strukturen des Spaniers besser verstand als ihre Gegnerin. Sie verfügte über Raumvorteil und konnte am Königs- und Damenflügel angreifen. In schwieriger Stellung unterlief Foisor ein Versehen und Weiß konnte in ein gewonnenes Endspiel abwickeln.

Wang, Annie ½-½ Paikidze, Nazi
Paikidze kam zu einem deutlich besseren Endspiel, doch Wang verteidigte sich hartnäckig und konnte sich ins Remis retten.

Kf2 $1 fxe5 25. f5 {and White is dominating.}) 23... f6 (23... h5 $1 {is strong, but a really tough move to find. The idea is that after} 24. gxh5 gxf4+ 25. Kxf4 Rxe5 {The h-pawn is hard to hang onto, and Black is doing fine.}) (23... gxf4+ 24. Kxf4 Rxe5 25. Bxh7 {is better for White.}) 24. Bf5+ (24. Kf3 {Would be my choice, stepping off the e-file. The line would go} gxf4 25. Bf5+ Bd7 26. Bxd7+ Kxd7 27. exf6 Re3+ 28. Kxf4 {and Black has super active rooks, but needs to play accurately to fight against the pawns. The best move is} R8e5 $1 {With the idea of Ke6 and playing against White's king. I don't think Black is in danger, but White is certainlly no worse.}) 24... Kb7 (24... Bd7 {is better, and White should still play} 25. Kf3 {with similar ideas to the previous position.}) 25. e6 $2 {Jennifer has played extremely well in this ending, but chess can be very unkind. Here she misses a nasty trick by Nemcova.} (25. Kf2 $1 {stepping off the file is very promising for White.}) 25... Bd7 26. Be4+ Kc8 27. exd7+ (27. f5 {was certainly what Jennifer had planned, but it fails to} Bxe6 $1) 27... Kxd7 {The e4 bishop cannot be saved.} 28. Rhd1+ $6 {Understandable, but this doesn't help White.} ( 28. fxg5 Rxe4+ 29. Kd3 fxg5 {and White should try to eliminate pawns with} 30. h4 $1 {Black is still much better here, but there are reasonable chances for a draw.}) 28... Kc8 29. Kd3 (29. Rd4 c5 {is not helpful at all.}) 29... Rxe4 30. fxg5 fxg5 {White's rook on d1 is fairly useless here.} 31. Rg1 $6 {This is the beginning of the end.} (31. c5 bxc5 32. h3 {was the best defense, cutting her losses. It's still going to be a long road.}) 31... Re2 $1 {Nemcova correctly puts her rook on the 7th, but the main idea isn't to take any pawns.} 32. h4 $2 (32. c5 {was again best, but it looks grim after} R8e3+ 33. Kc4 Rc2) 32... R8e3+ 33. Kd4 c5+ 34. Kd5 Kc7 $1 {White's king is active, but unfortunately it works against her here.} 35. Rbd1 Re5# {Katerina continues to roll through the tournament. This one wasn't easy, however, as Jennifer had good chances for advantage for much of the game. Unfortunately for her, her efforts were derailed by sly trap.} 0-1

Jennifer Yu fiel einer schönen Kombination zum Opfer.
