For patriotic American chess players, July proved to be a lost month. We started celebrating the month when we declared independence from foreign kings and held three coronation ceremonies at home.
New York General Manager Hans Nieman is the new American youth champion. He won his championship in a draw on Sunday because of his three closest opponents-General Manager Brandon Jacobson and IM Pula Vin Balakrishnan and David Brodsky-unable to catch him in the ninth and final round. In addition to honors and bonuses, Nieman also reserved a seat in the 2022 US Closed Championship.
IM Annie Wang won the American Junior Women’s Championship for the second time in a row. On Sunday, he drew with his main competitor WCM Ruiyang Yan and won the 10-man championship by a whole point advantage.
The silver hair series is more dramatic because general manager Larry Christiansen defeated general manager James Tayan in the final round, caught up with front-runner general manager Gregory Kedanov, and quickly entered the postseason in the US Senior Championship. Match. Kedanov won the championship for players aged 50 and over in two playoff games with a score of 1.5-1/2.
All three games are played at the St. Louis Chess Club.
Despite his short playing time, Christiansen demonstrated the shrewdness and outstanding endgame skills of some veterans in the key game with Tarjan, and moved to the corner of the board with a clever bishop to ensure victory. It takes a victory to catch up with Kedanov. Christiansen got what he wanted from this England start as Black. It is a dynamic position with many pieces on the board. The process of the game started and the dust settled early: 14. Kh2 d5 15. Be3! ? b6 (dxc4!? 16. bxc4 Bxc4 17. Rac1, White’s empty position and strong bishop pair provide a good compensation for the pawn) 16. Qa4 c5 17. cxd5 Ncxd5, Black ensures that the three-to-two back pawn is in the majority , Which will be shrouded in almost all subsequent manipulations.
Moving forward with the piece 27. Kg1 b5 gives Black the first obvious initiative. Suddenly, the more positions are traded, the more important the pawn imbalance becomes. With 39. Kg2 a6 40. e3?!, Tarjan prevented any annoying e4-e3 breakthrough for Black, but severely restricted his bishop in the process. This becomes crucial when Black finally gets a passing c-pawn and Christiansen cleverly uses the final White inaccuracies to clear the pawn’s path to glory.
Therefore: 47. Rxc4 bxc4 48. f3? (See chart; a failed step-White had to use 48.Kf1! Ke6 49.Ke2 Kd5 and challenged Black to find another way to break through) Ba1! ! (A good idea, put the bishop in the corner so that the pieces can keep up, Ba1-b2 will decide) 49. Ba3 (Kf2 c3 50. Ke2 Bb2 51. Kd1 exf3 and win) c3 50. Bc5 Ke6! (One advantage of 48…Ba1 is that now 51. fxe4 c2 52. Ba3 Bc3! 53. Bc1 Ke5 54. Kf3 g6! will leave a deadly zugzwang soon after his pawn is finished) 51. Bd2 c2.
Black’s c-pawn will eventually become the queen. Tarian resigned.
Wang’s most notable victory was a fierce tug of war with WFM Sophie Morris-Suzuki in the second round. When the real battle began, the two players showed some impressive theoretical foundations, rattling in more than 20 moves on the fashionable Sicilian line.
23. After Nb3 Rdc7, White seems to control the commanding heights, but like so many Sicilians, Wang’s defense is difficult to break. If there is a correct breakthrough, her center will prove to be strong.
Black entered the classic…d6-d5 release move, but failed to follow up the attack on the back wing, wasting the move, because Morris Suzuki controlled the d-file and placed her knight on the strong column. After 40. Qd3 Rb8 41. Ned6! (Let Black get rid of her poor bishop, but create a new goal in the King’s defense) Bxd6 42. Nxd6 Qc7, White could have maintained the advantage with a line like 43. Kb1! Rg8 44. Qf3 Qe7 45. Qe3 Rb8 46. Nc4 Qc7 47. Rd6 a5 48. Rxf6, it looks close to winning.
On the contrary, on 43. Rf2? ! 8 way! (The pin allows Black to climb back into the game, and as both players face time constraints, the tactics begin to heat up) 44. Rxf6 Kb8! (Threat 45…Nc8 is no longer checked as a knight capture) 45. Qd2? (Now White must find a very computerized 45.Re6!!!, the point is that 45…Nc8 can be hit by the unexpected 46.Ne8!Rxd3 47.Nxc7 Rxh3 48.Nxa6+Kb7 49.Nxb4 and win one Win the end) a5 46. Qd3 e4 47. Qg3? (The better way to lose the Cavaliers is 47. Qxe4! Rxd6 48. Rxd6 Qxd6 49. Qxh7, there is a real chance to draw lots in the endgame) Nd5 48. Re6 Qc3+! ? (Good enough, but 48…Qg7+ 49. Kc1 Qa1+ is a faster and more reliable victory) 49. Qxc3 bxc3+ 50. Kc1 Nc7 51. Rh6 52. Kd1 Nb5 53. Ke2 Nxd6 (the bad star eventually falls) 54 . Rxh ?, when 54.kxe3! Rd7 55. a4, will build a fort on Black’s car, and the Cavaliers will have trouble attacking.
The Black Knight, the car, and the electronic soldier proved a powerful trio, forcing Morris Suzuki to also abandon her car. Perhaps out of pure motivation, players have been playing it to mate.
