White is two pawns up, but her considerable advantage has begun to slip away. 28...Nd3? 28...Ne2 was the way to defend. 29.Qc2 Qxc2 30.Bxc2. Now White keeps her pawns and can use them to secure the win and get Irina the US Women's Championship: 30...Ne5 31.b4 Nf3 32.Rc1 Kg7 33.Bd1 Ne5 34.b5 Nd3 35.Rb1 Bd4 36.b6 Nxf2+ 37.Bxf2 Bxf2 38.b7 Rb8 39.Bg4 Bd4 40.Bc8 Be5 41.h3 Bd6 42.Kg2 Kf6 43.Kf3 Ke5 44.Ke3 Kf6 45.Kd4 Be5+ 46.Kc5 Bd6+ 47.Kb6 Ke5 48.Re1 f6 49.Bf5 Rh8 50.Rc1 Rh4 51.Rc6 Rxe4 52.Bxe4 1-0.

Black has been persuing a winning endgame successfully, and now only needs to push the e-pawn to clinch the title of US Junior Champion: 75...e2 76.Nf2+ Kf5 77.Nd3 h3+ 78.Kxh3 Ba5 79.Kg3 Ke4 80.Nc5+ Ke3–+. But Parker Zhao commits and eleventh-hour inaccuracy: 75...Bd6? 76.Nf2+ Kf4 77.Nd3+ Ke4 78.Nf2+! Kd4. 78...exf2 79.Kxf2 and the wrong colored bishop ending is drawn. 79.Kf3 h3 80.Nxh3 Kd3 81.Nf2+ ½-½. Sic transit gloria mundi – now Parker has to fight on for another day.
IM Sam Shankland blew his opponent off the board, making it a three-way tie atop the Junior leaderboard.
Final standings (after nine rounds) – Juniors
The 2010 U.S. Junior Closed Champion will be determined by an Armageddon playoff, which will take place at 10 a.m on Tuesday. Robson, by virtue of being first on tiebreaks (the ones used in Saint Louis, which are not the same as those used by our program above), has elected to receive a bye in the first round of the playoff. Zhao and Shankland will play a game to determine who will play Ray Robson for the championship.
Armgeddon playoff finalists Parker Zhao and Ray Robson
The third in contention: Sam Shankland
In this game, both players will bid on how much time they are willing to start with, between 1 minute and 45 minutes. Whoever bids the lesser amount of time has the option to choose his color, with the black pieces getting draw odds (meaning that in the case of a draw, black is declared the winner). Whoever loses the bid will receive a full 45 minutes, with both players receiving a 5 second increment for each move.
The winner of that game will have his choice of color in the championship game, with black again having draw odds. In the championship game, each player will have 45 minutes with a 5 second increment for each move.
