Three of the four semi-final matches went to tiebreaks, and the fans got their money's worth, too. In the top match, Shulman drew the first game with Black pretty easily in an IQP Tarrasch French and then won a very nice game with White. Hess may have surprised Shulman with his choice of opening (the King's Indian), but it looked like Shulman had a better feel for the resulting positions. The losing move might have come as soon as 19...f5. Hess hoped for kingside play, but it was Shulman who took over on that wing and won with a terrific demonstration of power chess, culminating in a finely conducted mating attack.
In the first ladies' semi-final to finish, Abrahamyan won both games against Baginskaite. In the first game, Abrahamyan stood a little better with White when - probably in time trouble - Black blundered with 40...f5??, when it was soon over. (40...Rxc3 still favors White, but Black's position remains playable.) Game two was a similar story: Abrahamyan stood a bit better and Baginskaite was getting short of time when she blundered the game. This time the culprit was 38.Rf7? (38.Rxd3=+) Qd6? (38...Qh4-+) 39.Rxg7+?? Nxg7 and 0-1.
Finally, there was the utterly crazy match between Krush and Zatonskih. Recall Krush beat Zatonskih in the preliminary rounds, lost the first "regular" game of their semi-final match and then bounced back to force a playoff. In the first game Krush had White, and the position eventually reached bishop (for Krush) vs. two pawns, dead draw. Krush could have held the game in 1-minute chess without a sweat. Somehow, though, her mind switched off, and rather than, say, give up the bishop for one of the pawns (e.g. with 63.Bxb4) and draw the king and pawn vs. king ending, she allowed her opponent to force promotion. 64.Kb1 was the normal move, but 64.Bb2+?? left White without a defense to the straightforward plan ...Ka2, ...b3, ...a4-a3, ...b2+ and ...b1Q.
I'm not sure I'd be able to face another human beings for a few hours after such a loss, let alone play another game, but to Krush's considerable credit she not only showed up for game two but won it with Black. Wow! The key points there were Zatonskih's 34.Rc1?, blundering a pawn, and then the "exchange of courtesies starting with Black's 40th move. Had Krush met 40.Qe3 with 40...e5, she would have won straightforwardly and collected a well-deserved point. Instead - in mutual time trouble - she played 40...Qxa2??, and after 41.hxg6 hxg6 Zatonskih could have made it game, set and match with 42.Qh3. This threatens mate on h8, and the problem is that 42...e5 hangs the rook on c8, while 42...Kf8 43.Bf6 Ke8 almost escapes, but not quite: 44.Rxe6+! is a crusher. Fortunately for Krush, White played 42.Bf6??, and after 42...Bf8 the scare was over and Black soon won.
Then it was time for the Armaggedon game, and just as they did last year, they held a bidding procedure to determine colors and clock times. Both players bid on how much time they would be willing to take with Black, and the low bid gets Black with the amount of time she bid, plus draw odds - meaning that if the game ends in a draw Black "wins" the match. The bids could be anything from 45 minutes on down, and Zatonskih bid 27 minutes while Krush requested...45 minutes! She had been obtaining advantages with White and felt confident that replaying the same variation would give her good chances.
She got the line she wanted, but Zatonskih played better this time around. Krush had a tough time finding a plan, and after Zatonskih's 19...Nh5! with the idea of ...f5, Black achieved a very nice blockade. Krush's last chance to do something was around move 24. She didn't have any advantage, but perhaps some exchange sac ideas like 24.Rxh5 gxh5 25.Rg1+ Kf8 26.Bf4 or 24.Rcg1 Ng7 25.h5 h6 26.Rxg6 Bxg6 27.hxg6 could help her create some practical problems. After 24.Rg2 Ng7 25.Ke3 Ne6 26.Bf4 Rd5 there was just nothing for White to do but wait and see if her ossified center would collapse. (It did.)
So Zatonskih, who must be physically, mentally and emotionally exhausted by now will take on Abrahamyan in the women's final, while last year's finalists, Kamsky and Shulman, will vie for the championship a second straight year. Remarkably, both players have been undefeated the past two years (last year's championship was settled by an Armaggedon draw in Kamsky's favor).
