Day 6 recap by IM Kostya Kavutskiy
OPEN SECTION – CHAMPIONS BRACKET
SO-NAKAMURA | ยฝ-ยฝ, 41 moves | PLAYOFF NAKAMURA 3-1
After yesterday’s relatively quick draw So went for the highly theoretical 4.Qc2 Nimzo-Indian in the second classical game, but Nakamura was well-prepared and neutralized So’s prep quite effectively. After some trades the players ended up in a drawn endgame, taking the match to a playoff.
In the first rapid game So was very close to winning a rook and knight endgame, but slipped up during a time scramble and was forced to give up his knight for Nakamuraโs passed pawn. However it was not easy to convert the position, and Hikaru even allowed So to trade off all the pawns and reach a drawn rook and knight vs rook endgame. Unfortunately for Wesley his king was caught in an awkward place to start, as he ended up blundering and losing the game.
In the second rapid game So was able to bounce back and win on demand, opting for a Modern Defense where he managed to outplay Hikaru in a queenless middlegame. This took the playoff to blitz, which was then dominated by Nakamura, who again won the first game as Black and then took the second game against Wesleyโs Modern Defense as well, clinching the match.
OPEN SECTION – ELIMINATION BRACKET
Dominguez started the match with his usual Petroff Defense, but sacrificed a pawn out of the opening in exchange for the bishop pair and long-term compensation. He was fine for the most part, but then started to slip during his time-trouble in an opposite colored bishop endgame. A further blunder allowed Aronian to pick up the first game.
In the second game Dominguez went for the Berlin Endgame as White, and was able to put some pressure, but Aronian defended well and never allowed a serious chance. Towards the end Dominguez managed to break through in a bishop endgame and even win Aronianโs bishop, but was left with a textbook drawn endgame, with the wrong color bishop for his rook pawn.

LEE – KRUSH | ยฝ-ยฝ, 41 moves | PLAYOFF KRUSH 2-0
The second classical game came down to the wire in an extremely complicated rook endgame with passed pawns for both sides. At one point Lee was winning by force, but in heavy time pressure she let Krush escape with a draw, taking the match to a playoff.
Alice took White in the first game of the playoff and reached a pleasant rook and bishop vs. rook and knight endgame, but ended up blundering all of her kingside pawns in a time scramble, eventually leaving Krush with four connected passed pawns against a bishop and a completely winning ending.
In the second game Lee played the Queenโs Gambit Declined, and despite only needing a draw to advance Irina played very aggressively, castling queenside and allowing a double-edged middlegame. However her play worked out as her attack crashed through first, and she was able to win the second game as well.
WOMENโS SECTION – ELIMINATION BRACKET
PAIKIDZE – TOKHIRJONOVA | 2-0
In the first game Tokhirjonova took White and played an English setup, looking to put pressure on Blackโs queenside. Paikidze reacted with a typical Kingโs Indian setup and was a bit worse until Begim misplayed her position, allowing Black to take over the queenside. A nice queen desperado tactic then finished the deal.
In the second game Paikidze played the Catalan and was better throughout the game, but in mutual time-trouble made a practical decision to sacrifice her bishop in order to force a perpetual check. Given the match situation Tokhirjonova tried a hail-mary by walking her king out into the open, but ran into a tactic that ended the game immediately.
