Press release of the Saint Louis Chess Club

Day 9 Recap

By IM Kostya Kavutskiy

U.S. Senior Championship

Playing Black against GM Igor Novikov, Kaidanov entered the extremely sharp Botvinnik Variation, but did not have any chances to play for a win in a long theoretical line. The game was then drawn after the players traded down into an equal rook endgame, finishing shortly past the first time control. 

his gave Christiansen the chance to catch up, and he made the most of it as he managed to outfox GM James Tarjan in a slightly better bishop endgame, finding a study-like resource to win the game in brilliant style.

48...Ba1!! was a brilliant shot to win the bishop endgame, as White couldn’t stop the c-pawn in view of c2-c3 and Bb2 next. | 0-1, 52 moves

U.S. Junior Championship

After yesterday’s loss to IM Christopher Yoo, GM Hans Niemann started the final round just half a point ahead of his nearest rivals GM Brandon Jacobson, IM Praveen Balakrishnan, and IM David Brodsky. Playing White against Jacobson, Niemann utilized a safe line in the English Opening and stood better for most of the game, though missed some chances to secure a large advantage.

Meanwhile, IMs Brodsky and Balakrishnan faced each other, both needing to win in order to possibly tie for first and force a playoff tiebreak. It was Balakrishnan who had the better position in the middlegame, as he built up a strong attack against White’s king, but Brodsky defended well, and the game eventually petered out into a draw by repetition, with neither player being able to push for a win.

Once Brodsky and Balakrishnan agreed to a draw, Niemann forced a draw in an equal rook endgame against Jacobson, securing first place in the tournament and clinching the title.

U.S. Girls' Junior Championship

In the U.S. Girls’ Junior, IM Annie Wang just needed a draw in order to clinch the title, and was paired against her main rival at the end, WCM Ruiyang Yan, who going into the round was a full point behind. Annie prepared well for her opponent’s Ragozin Defense, essaying a drawish variation that left her with virtually zero losing chances. After trading into an endgame in which only White could play for the win, Ruiyang offered a draw in a slightly worse position, giving Annie clear first place in the event.

Black was not able to generate any winning chances, as White’s position was simply too solid. | ½-½, 36 moves
