2019 U.S. Junior, Girls' Junior and Senior Championship Recap – Round 5


by Josh Friedel
All three sections had their share of interesting games, though the Juniors were definitely the most bloodthirsty. In a day of all decisive results, Nicolas Checa maintained his lead by winning a nice game. Awonder Liang and Joshua Sheng also won, and remain tied for 2nd just half a point back. Carissa Yip and Rochelle Yu both drew their games, and thus maintain their positions of clear first and 2nd respectively. Alex Goldin won again, allowing him to tie for first with Alex Shabalov, who failed to convert a promising position against Larry Christiansen.  Let’s take a look at what happened.
 
U.S. Junior Championship

Hans Niemann got a difficult opening position against Awonder Liang, then found himself with a weak king after his fianchettoed kindside bishop got traded. Awonder delivered checkmate soon after, moving him up to an impressive four out of five.  
Jennifer Yu’s woes continued today, as she lost a rather one-sided game to Atulya Vaidya. To his credit, Atulya played quite well and capped off his first win of the tournament in devastating fashion. Craig Hilby and Nicolas Checa got involved in a highly theoretical duel in a Bb4+ Nbd2 Catalan. Checa seemed to know the line better, and after Craig prematurely captured a rook on a8 instead of continuing his initiative, Black seemed to have an excellent position. Nico converted his edge in accurate fashion.  
Andrew Tang had Brandon Jacobson under pressure for a long time, but Brandon was defending admirably. He ended up losing in a tricky king and pawn ending, however, which allowed Andrew to take his first point of the tournament. Joshua Sheng won a wild game against John Burke, one in which the commentators and players alike were highly unsure of what went on. In the end, Joshua staved off pressure to his king, then zoomed in on his opponent’s to finish off a nice victory.

U.S. Girls’ Junior Championship

The girls had one of their more peaceful days of the tournament, but you wouldn’t know it by the positions they got. Agata Bykovtsev sacrificed a piece against Maggie Feng, and seemed to get very promising compensation. Maggie managed to navigate towards an ending where she held Black to a draw.  
Carissa Yip wandered her king into the center in a complex ending against Thalia Cervantes.  Thalia could find nothing better than giving a perpetual, however, in a position that looked completely crazy. Emily Nguyen got a favorable isolated pawn position out of the opening against Veronika Zilajeva, then won a pawn and traded into an endgame. While she was disappointed with her conversion, she never really let her opponent back into the game, and in the end got a smooth victory.  
Ruiyang Yan had an extra piece against Martha Samadashvili’s pawns, and the piece proved to be stronger in this game. While the conversion was never easy, a late game slip by Martha allowed her to win more easily. Rachael Li, with 0/4, played against the 4/4 Rochelle Wu this round. You wouldn’t know it by her play, however, as she absolutely took it to the tournament leader. In the end, however, Rochelle found a way to sac two exchanges to complicate the game. The players agreed to a draw in a position that could have really gone either way.  
 
Rochelle Wu looked nervous today, but only gave up half a point, allowing her to stay ahead

U.S. Senior Championship

The seniors played a lot of sharp games, but only some ended in a decisive result. Alex Yermolinsky had what looked like an unpleasant position against Jaan Ehlvest’s King’s Indian, but the players agreed to a draw at move 30 in a position with much life left in it. Maxim Dlugy played a sharp variation of the London against Igor Novikov, and played an interesting queen sacrifice that led to a promising position. Igor navigated the complexities better, however, and ended up raking in his first full point.  
Gregory Kaidanov got a dominating center against Joel Benjamin, and it looked as if he might score his first win. Joel found some nice defensive resources, however, and they agreed to a draw in an ending where neither could make progress. Alex Goldin had a dubious-looking opening position against Alex Fishbein, but Fishbein made a few missteps, which allowed Goldin to trade into an endgame up two pawns. As was the case yesterday, he made no mistakes in the conversion.  
Alex Shabalov and Larry Christiansen are both known for their attacking play, and their game did not disappoint. After Larry C surprised Shabba in the opening, Alex navigated his way into a very strong attack. Larry showed his defensive prowess, however, and was able to finagle a draw after a sharp tussle.

2019 U.S. Junior, Girls' Junior and Senior Championship Recap – Round 4


by Josh Friedel
Today’s round had a lot of action in all sections. Nicolas Checa took the lead with a fine victory over Andrew Tang. Both Rochelle Wu and Carissa Yip won topsy-turvy games, and seem to be running away in the Girls’ tournament with 4/4 and 3.5/4 respectively. Alex Shabalov survived a lot of strong pressure from Joel Benjamin, and maintains a half point lead in the Seniors over Larry Christiansen and Alex Goldin. Let’s break down what happened in each event.
U.S. Junior Championship

The first game completed in the Junior was a heartbreaking one. IM Craig Hilby got his moves confused and had to resign after hanging a bishop against IM Hans Niemann. Such blunders occur now and then, even by super strong players, but they always leave the players and viewers in shock.
Atulya Vaidya has been having a rough event, and today he played solidly against Joshua Sheng, hoovering off most of the pieces in short order. They agreed to a draw in a balanced rook endgame. The US Women’s Champion continued to struggle, as Jennifer Yu got a cramped position as Black against Brandon Jacobson. Brandon finished off the game in resounding fashion by sacrificing a knight on f6 and taking advantage of Black’s lack of coordination.

Awonder Liang shook off yesterday’s loss by taking risks and pitching his queenside as Black against John Burke.  His risk paid off handsomely, and he crashed through by giving his queen for two rooks and a vicious 1st rank attack, winning the game in short order. Lastly, Nicolas Checa found an initiative against Andrew Tang, and eventually hunted down the Black king.  This win put Nicolas in clear first place with 3.5/4.

Nicolas Checa played a very nice game today, and is currently in the clear lead with 3.5/4

U.S. Girls’ Junior Championship
 
“I hated it,” Rochelle Wu said about her position after the game. She had severe positional problems against Ruiyang Yan, who was playing an excellent game and dominating the entire board. Similar to previous rounds, however, Rochelle proved her resourcefulness. She opened the game by pitching a couple pawns, then found a nice tactical resource which won a rook out of the blue, forcing Yan to resign. Rochelle is an incredible 4-0, but Carissa moved to 3.5 today by beating Rachael Li as Black. The game was anything but clear, and the 9-year-old definitely had her chances, but in the end Carissa’s pressure proved to be too great.
Thalia Cervantes and Emily Nguyen played a game that had a lot of potential for sharp play, but none of it really materialized. The players agreed to a draw after a lot of pieces came off in a locked position. Agata Bykovstev seemed to have some pressure against Martha Samadashvili, but she soon found herself in trouble when she traded her queen for two rooks. Martha took full advantage of White’s weak king position, and eventually reeled in the full point in a queen vs. rook endgame.
In the final game of the day, Veronika Zilajeva had a thrilling game against Maggie Feng.  Maggie’s king ran up the board, and for a while it was unclear who was better. Unfortunately for Feng, she captured a pawn on a5 at the wrong moment, and allowed Veronika to deliver checkmate. Veronika found it, and thus won her first game of the tournament.

Veronika Zilajeva and Maggie Feng had quite a battle this round

U.S. Senior Championship

Larry Christiansen and Alex Fishbein played an interesting Nimzo Indian, and the position became extremely locked after an f5-f4 push. Neither side could find a way to break through, and they agreed to a draw on move 31.  

Igor Novikov and Gregory also drew a solid game. Neither side made errors in a drawish line, and they agreed to a draw in a knight endgame. Jaan Ehlvest put a lot of pressure on Maxim Dlugy’s weak king. While Max found a lot of tricks, as he has in previous rounds, eventually Jaan extinguished all of them and forced a win in a queen endgame. Joel Benjamin and Alex Shabalov had an incredible battle, and for most of the game Joel was clearly in charge. Shabba put all of his resourcefulness on display to make things complicated, however, and Joel finally acquiesced to a draw in a rook endgame.
Finally, Alex Goldin had an instructive positional win against Alex Yermolinsky.  He transitioned from a hanging pawns position to a rook endgame up a pawn. As Goldin commented after the game, the “Russian School” helps in such positions, and he converted it with great accuracy.

2019 U.S. Junior, Girls' Junior and Senior Championship Recap – Round 3


by Josh Friedel 
While round one had a lot of blunders and quick victories, the players seemed to settle down for round two. There were several long, tough battles, and the players in all sections showed they were willing to fight it out to the very end. Let’s take a look at what happened.
U.S. Junior Championship
IM Hans Niemann had laptop issues before his game against WGM Jennifer Yu, but that didn’t stop him from winning a nice game. Once again, Jennifer took a lot of risks early in the game. While it might very well have been sound with best play, she lost the thread and couldn’t hold her position together. GM John Burke seemed to have chances on the white side of an Exchange Ruy structure against GM Andrew Tang, but after Black sacrificed a piece, John didn’t find anything better than allow a perpetual.  
IM Joshua Sheng had a crushing position and huge time advantage against IM Craig Hilby.  Craig held tough, however, and Joshua was unable to finish him off. They eventually agreed to a draw in a bishop endgame. GM Nicolas Checa found himself on the worse side of a Carlsbad structure against IM Brandon Jacobson, and was certainly worse for much of the game, but managed to hold the draw in the end.  
Atulya Vaidya was holding his own against top seed GM Awonder Liang for a long time in a rook and knight endgame. Unfortunately for the bottom seed, he went astray at the last minute, and Awonder took full advantage to convert the win and move to 2-0.

U.S. Girls’ Junior Championship

WIM Rochelle Wu said in the confessional booth that she was happy with her prep and position, and she used this confidence as Black against Veronika Zilajeva. With this win, Rochelle is off to a flyer with a quick 2-0 start.  
FM Carissa Yip, on the other hand, got a highly suspicious opening as Black against WIM Agata Bykovtsev. Last year’s champion showed her class and turned the tables, however, to eventually win the game and join Rochelle in the lead.
WIM Emily Nguyen finally won Martha WFM Martha Samadashvili’s isolated pawn, then converted her endgame advantage with authority. FM Maggie Feng played a nice game, and won a complex struggle against WIM Thalia Cervantes. She gained a central pawn advantage in the middlegame, and eventually ran those pawns to victory.  
In the battle of the two youngest participants, Ruiyang Yan nicely outplayed Rachael Li in a bishop endgame. Black certainly had drawing chances at some stage, but in the end a couple slips was all it took for Yan to take home the point.

Igor Novikov seemed to be pressing against Alex Fishbein, but went astray by allowing Black to advance his pawn on d4. Had he captured on d5 Igor would have preserved his advantage, but as it happened the players agreed to a draw as soon as the knights traded. 
Jaan Ehlvest seemed to have the better side of an opposite bishop endgame against Gregory Kaidanov, but was unable to make anything of the position, and the game petered out into a draw. Joel Benjamin won a crazy game against Alex Yermolinsky. His e6 pawn push early in the opening led to an exchange up endgame, but not a simple one, and in the end it took some errors from Yermo’s side for Joel to wrap up the game in his favor.  
Alex Shabalov outplayed Maxim Dlugy with the Black pieces. As he did yesterday, Max fought on in a lost position for a long time, but in the end Shabba was able to navigate the complications and reel in the point.  Finally, Larry Christiansen put a lot of pressure on Alex Goldin in the battle between the leaders, and in mutual time trouble he was able to win a pawn.  
Round three saw a couple of the leaders get knocked off as well as numerous entertaining battles.  Noteworthy results included leaders GMs Larry Christiansen and Awonder Liang getting knocked off by GM Alex Yermolinsky and IM Joshua Sheng respectively. Rochelle Wu, on the other hand, won a third game in a row and is 3-0 in the Girls’ section. Let’s break down the action.
 
U.S. Junior Championship

Brandon Jacobson, with the white pieces, won two pawns out of the opening against Atulya Vaidya. It looked like he was on the road to an easy victory, but he got seduced into sacrificing a rook for an attack. Brandon miscalculated, however, and was forced to draw the game with a perpetual check. 

Andrew Tang gained a nice pawn structure advantage against Hans Niemann. Hans defended well, however, and eventually the players agreed to a draw in a balanced knight endgame.  Craig Hilby found himself under fire right out of the opening against John Burke. Burke lost his way, however, and then Hilby was the one in the driver’s seat. Unfortunately for him, Craig struggled to take advantage, and they eventually agreed to a draw in a rook endgame. 

Jennifer Yu played an exchange slav against Nicolas Checa, and while in the confessional booth she said that she expected a quieter game, that’s not what happened.  She sacrificed a piece for three pawns, but her pawns proved not to be super impactful, and eventually Nicolas converted his extra knight. Top seed and tournament leader Awonder Liang played some unusual ideas in a Spanish as White against Joshua Sheng, but it didn’t work out well and he found himself in a difficult situation.  While he certainly had chances at some point, eventually he dropped two pawns, and Joshua took the full point in convincing fashion.

U.S. Girls’ Junior Championship

Carissa Yip had a clear positional advantage against Ruiyang Yan’s Sicilian, but Black defended quite well. Carissa allowed the game to simplify too much, and the players agreed to a draw in a balanced endgame. Veronika Zilajeva won a pawn as Black in a French Defense against Martha Samadashvili, but allowed White’s queen to penetrate her position. Martha found a beautiful pawn sacrifice, and delivered mate shortly after. 

Emily Nguyen outplayed Maggie Feng with the black pieces, and converted her advantage in convincing fashion. This was her second win in a row. Rachael Li was holding her own against Thalia Cervantes, and the game looked to be heading towards a draw for the longest time. Rachael lost her way in a bishop ending, however, and Thalia was merciless in bringing home the point. 

Rochelle Wu had nice opening advantage against Agata Bykovtsev’s Najdorf, but she went astray by allowing Agata to capture her dark-squared bishop. Black was clearly winning, but Bykovtsev got low on time, and ended up missing a nice resource that allowed Rochelle to give checkmate. This win put Wu on an incredible 3-0 score. 
Rochelle was in serious trouble against Agata, but she looked completely unfazed throughout
U.S. Senior Championship

Maxim Dlugy had a normal position as Black against the Slav, but at an unfortunate moment he allowed Gregory Kaidanov to steal a pawn. Max is a tricky customer to finish off, and Gregory went astray by allowing Black to capture his b-pawn, after which the players agreed to a draw in short order. 
 
Alex Goldin seemed to have a difficult position against Jaan Ehlvest, but in mutual time pressure neither player wanted to take excessive risk, and a draw was agreed on move 31. Alex Shabalov and Igor Novikov played an extremely complex Najdorf. Igor navigated the complications quite well for some time, but one slip allowed Shabba to capitalize and convert into a won position, which he converted well. 
 
Alex Fishbein and Joel Benjamin were involved in a sharp tussle, and at some point Alex seemed to have great chances to win. Joel navigated his way to a pawn down ending, and expertly held it after a couple missteps by the White player. Tournament leader Larry Christiansen took excessive risks as Black against Alex Yermolinsky, but he found himself in a difficult position soon after.  Yermo played very well to convert his positional edge into victory.
You have to tip your hat to Alex Yermolinsky, who won a nice game against Christiansen
