SAINT LOUIS, September 12, 2011 -- What a difference a day makes! Only one day after their strong showing, the Queens had a ‘very bad day at the office.’ A near perfect 4.5 – 0.5 result in the chess960 round, combined with a 3.5 -1.5 score in the rapids added 6 full points to Kings’ lead, for a total of a mountainous 10-point advantage. Indeed, it would take a heroic performance by the women to reverse such a margin. Once again the final day’s tally does injustice to the Queens, when we consider the positions on the boards in several of the games.
Today’s novelty idea for the drawing for the chess960 position was a ‘wheel of fortune’ roulette wheel, spun by Eric van Reem, who among other projects revised the chess960 rules for the FIDE handbook. Each spin helped determine the placement of each chess piece.

One can find few flaws in GM Hikaru Nakamura’s chess960 victory over GM Alexandra Kosteniuk. He gained an early advantage when he forced his opponent to relinquish her dark-squared bishop. Soon thereafter, the Kings’ top board’s control of the only open file brought dividends in the shape of a healthy pawn. The best the Russian could do was to liquidate to an opposite-color-bishop endgame, but alas it was one that Nakamura managed to convert in record speed.
Their rapid battle was not at all one sided. Ambitious as always, Nakamura played the King’s gambit – an opening that was a lot more inspiration than preparation! No sooner than move 14 did he have to gamble with a sacrifice of a knight for two pawns and a strong center. There was enough compensation for the material, but after some inaccuracies black’s position was tenuous. The pendulum swung on move 21 ...

... with black to move, one can see the coming idea of 22.Qa7, and also that ‘stopping it’ with 21…Kb8? gets hit with 22.Bxc7+ Kxc7 23.Nb5+. Hence 21…Bxc3! was called for, and after the forced queen trade (22.bxc3?? Qb1 is mate!), black is clearly the happier camper. Inexplicably 21…Nd6?? was played, and after the aforementioned 22.Qa7, it was curtains for black.
In the GM Kateryna Lahno – GM Ben Finegold, game one saw black somewhat better for most of the game, but it is unclear if his initiative was enough for a full point. After some further inaccuracies by white, a rook ending ensued, where victory seemed just a matter of technique by black. This is where the old cliché that ‘all rook endings are drawn’ once again proved wise. As Lahno’s husband, GM Robert Fontaine, showed after the game, white missed a golden opportunity ...

... 44.f7! Of course the obvious idea is Kg5-f6, but what about 44…Kg7 by black? Well, 45. f8=Q+! is the resource! 45…Kxf8 46.Kg5, and despite black’s three (!) pawn advantage, there is no win. Unfortunately for the Ukrainian GM, she played 44.Kg5? Rg2+! 45.Kh6 b4, black pushed his b-pawn all the way down the board till it had to be taken, and then played Kf7 with an easy win.
Game two was a pacified Gruenfeld, where black more than equalized, and slowly outplayed white to get to the following position ...

... The continuation of 33…Qf1+? 34.Kh2 Bc4 35.Qxb6! won black a piece, but gave white a perpetual check and the desired draw. The better alternative was 33…Qc4!, leaving white tied up and hurting for good moves. 34.Kh2 b5 and black would have been on the verge of victory.
IM Jacek Stopa had a strong showing versus the out-of-form U.S. Women’s Champion IM Anna Zatonskih. Their chess960 game was an example of how fast one can get into trouble when they can’t find a proper set-up ...

... Already it is easy to see that the black pieces are all tangled up, and indeed the only way to fight on was to pitch the h4 pawn with 14…Nf6 15.Nxg6+ Rxh6 16.Qxh4. The game saw 14…Bh7?? 15.Ng4 and 1-0 on move 19.
Zatonskih sought redemption in the rapid game by playing very aggressively and offering a pawn, which was declined. She then pushed the black queen to h7. The rest of the black pieces however, remained active, and black offered a pawn of his own – which was accepted. The major piece ending was heading to a draw, when white blundered with ...

... 34.Kg3? Qxe4! 35.Rxa3 Qxe5+ 36.Kh3 f5! With a decisive advantage, which Stopa brought home in speedy fashion.
It is not often that a player gets a position with three minor pieces for a queen in a game. IM Marc Arnold managed to get that twice in two days! His opponent, IM Irina Krush temperamentally pseudo-sacrificed an exchange, only to fork white’s rook and bishop and win a piece, but white’s counter play was sufficient. The real excitement started when the black queen found itself overloaded, and black was forced into the following sequence ...
[imagefield_assist|fid=13331|preset=fullsize|title=|desc=|link=none|origsize=|align=center|width=375|height=375]
... 22...Qxd4+ 23.Rxd4 Bb6 24. Qe4 Nf5, and here 25.Kh1! was in white’s favor after either 25…Bxd4 26.g4 or 25…Nxd4 26 Qb7. After all of that excitement, the game was soon drawn by move repetition.
With the white pieces for the rapid game, Arnold said he decided to choose a less common opening, and play more quickly. It proved to be the right decision as he refuted Krush’s hyperactive plan of 11…Qa5?! and gained a steady plus. He could have remained up a queen for a rook and a bishop, but he preferred to give it back for a better endgame. Black had the draw within reach, but a careless series of moves brought on a winning bishop ending, and Arnold brought the point home.
Today marked the first victory for Kevin Cao in his split match with IM Martha Fierro. It was achieved in their chess960 encounter, where Cao built a very strong and mobile center, which he mercilessly pushed forward. His space advantage on the king’s side bore fruit on move 30 ...

... 30.Rxg6+! fxg6 31.Nh4, and the black position collapsed like a house of cards.
In the second game black was overconfident with his 14…f5?, allowing white to later take full advantage of its superior development ...
[imagefield_assist|fid=13333|preset=fullsize|title=|desc=|link=none|origsize=|align=center|width=375|height=375]
... 19.Rxd7+! Nxd7 20.Rd1 Kc8 21.Bxd7+ Kb8 22.exf5 gxf5 23.Bxf5 with a winning advantage that Fierro had no trouble cashing in on.
Today is a free day, and the players will have a chance to rest or enjoy a trip to the Gateway arch. Play resumes on Wednesday, and the Queens have their work cut out for them. Lest one forget, however, that in addition to the team prizes, there are also individual place prizes (and of course pride!), so there is plenty to play for!
