Fireworks in the Final Round of the 2016 North American Junior U20 Open

By IA William J. Broich

Upsets on boards one and two in the final round of the 2016 North American Junior U20 Open produced a four-way tie for first. The 2016 North American Junior U20 Open Chess Championship was held at the Airport Double Tree Inn in Irving, Texas, USA. The event began September 1 and concluded September 5.

The field consisted of four IMs, three FMs, one WIM, seven NMs, and one CM with the remainder of the field untitled. IM Ruifeng Li topped the field with an impressive FIDE rating of 2555.  The remaining IMs were Akshat Chandra (2483), Awonder Liang (2477) and Michael Bodek (2403). Nicolas Checa (2421) was the highest rated FM and he is an IM-elect.

Notably missing from this field was GM Jeffery Xiong (2647). Xiong recently won the World Junior Championship. While Xiong is the top rated chess player in the world born in 2000 or after, Li is the highest rated player in the world born in 2001 or after, based on the list of the top 100 juniors posted on the current FIDE website.  Li won the prestigious National Open held annually in Las Vegas, USA.  IM Liang is the top rated player in the world born in 2003 or after.  These young competitors represent a new generation of talented players from the United States.

There were numerous upsets throughout the tournament. Going into the ninth and final round five players had five points, one player had five and a half points and top seeded Li had six points. In the final round Li had black against Sheng on board one and Liang had black against Advait Patel on board two.

The first place winner receives the Gold metal, a GM norm and the IM title in this event.  Equal first after the tiebreak earned the IM title. Li, an IM, could earn a GM norm with a first place finish.  Liang, also am IM, had an opportunity to earn a GM norm if he won and Li lost. 

Both players, Li and Liang, kept a close eye on the game next to them. If Liang drew, Li could secure first place with a draw. If Liang won, Li would also have to win to claim first place.  

GM Timur Gareev annotates the games on the two top boards of the final round with the help of FM Advait Patel.  Did IM Liang push for a win forcing IM Li to also play for a win to get a GM norm?

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 Nbd7 7.Qe2 is not the main move but definitely one to be prepared for 7.f4 Qc7 8.Qf3 is the typical setup in these Bg5 Najdorfs 7...Qc7 8.f4 e6 9.0-0-0 b5 10.a3 Bb7 11.g4 Be7 12.Kb1 Rc8 13.Rg1 So far all the moves have been pretty standard. Now Black has to come up with something h6 14.Bh4 g5 This a common idea in these lines. Black is sacrificing a pawn in order to control the important e5-square. 15.fxg5 hxg5 16.Bxg5 Qb6 Black is introducing ideas like ..e5 and ..Rxc3. 16...Ne5? is simply met by 17.Bc1± and White pretty much has a free hand on the kingside. The bishop is a good defender on c1 17.Rg3 And White stops both of them with this move Rg8 18.h4 Ne5? 18...Rc4! and White is forced to give up a pawn with 19.e5 19.Rgd3 runs into Ne5 19.Be3 Rxc3! 20.bxc3 Nxe4 19...Nxe5 20.Bg2 White has too much loose stuff on g4 and d4 and potentially h4 if Bxf6. Bxg2 21.Qxg2 Rxd4 22.Rxd4 Qxd4 23.Qa8+ Kd7 24.Qb7+= 19.Bg2± Now Black just never gets enough for his pawn. Perhaps he saw the line with 18..Rc4 19.e5 but was trying to play for a win? Rc4 20.Nb3 b4 21.axb4 Rxb4 22.Rf1 Nfd7 23.Be3 23.Bxe7? Kxe7 Black's king is completely safe on e7 23...Qc7 24.g5 a5 25.h5?! 25.Nb5! Qb8 25...Qd8 26.Bd2 wins an exchange 26.Ba7 Qc8 27.Rc3 Suddenly it is White who is attacking on the queenside! 25...a4 26.Na2 Rc4?! 26...Rb6! This incredible resource actually saves Black 27.Bxb6 Qxb6 28.Nd2 Ba6 29.c4 Rxg5 and Black is getting some serious compensation for the exchange. Of course this line is very difficult to see for a human especially in a critical game like this. 27.Nd2 Rxc2 28.Nb4 Rxb2+? 28...Rc5 It's surprising why Black play this 29.g6 29.Bxc5? Qxc5 with great compensation 29...fxg6 30.Bh3 and White sitll has some pressure but Black is not lost 29.Kxb2+- At this point Black is just lost. White just needs to focus on keeping the king alive. Qa5 30.Rb1 d5 31.exd5 Bxb4 32.dxe6 Ba6 33.exd7+ Black throws the kitchen sink at White but it just isn't enough Kd8 34.Qd1 Nd3+ 35.Ka2 Qc7 36.Rg4 Qd6 37.Nc4 Qe6 38.Qxd3 Qxg4 39.Bb6+ 1–0

1.e4 c5 2.Nf3 d6 3.Bb5+ Nd7 4.0-0 a6 5.Bd3 Ngf6 6.Re1 e6 7.c3 Be7 8.Bc2 b5 9.d4 Bb7 10.Nbd2 Qc7 11.e5 11.Nf1 Rc8 12.Bd3 0-0 13.Ng3 is a typical position that arises but White doesn't really have a plan while Black will just advance on the queenside. He will just fianchetto the bishop on g7 and at the right moment to play ..e6-e5 to prevent any kingside operations from White 11...dxe5 12.dxe5 Nd5 13.Ne4 Bg5 is coming and although ..h6 makes castling hard for Black it is probably best Rd8 13...h6 14.Ng3 Now castling runs into Qd3 but White can't do anything about Black's king in the center 13...Nxe5? 14.Nxe5 Qxe5 15.Nxc5 Qc7 16.Nxb7 Qxb7 17.Qg4± An open position like this definitely favors White with the bishop pair and some prospects on the kingside 14.Bg5 0-0 14...Nxe5? 15.Nxe5 Qxe5 The tactics don't work out for Black 16.Nf6+ Nxf6 17.Rxe5 Rxd1+ 18.Rxd1 Nd7 19.Bxe7 Nxe5 20.Rd8+± 14...Bxg5? 15.Nd6+ Ke7 15...Kf8 16.Nxg5 Nxe5 17.Ndxf7+- is even worse 16.Nxg5 Nxe5 17.Ndxf7 Nxf7 18.Nxe6+- The attack far outweights the piece 15.Ng3 The threat of Bxe7 and Bxh7+ looks scary but Black has a way to stop all of White's plans g6?! 15...Bxg5!? 16.Bxh7+ Kxh7 16...Kh8 is enough for a draw and probably best 17.Nxg5 Nf4 18.Qg4 At first it looks like White is winning but Black has a simple draw Nxe5 19.Qh4 Nxg2 20.Qh3 Nf4 21.Qh4= 17.Nxg5+ Kg8 18.Qh5 N5f6 19.exf6 Nxf6 20.Qh4 and White has some ideas of Nh5 and Re3-h3 15...N7b6 is simple and natural 16.Qc1 Here Black has not created any weaknesses so it is harder for White to come up with something. 16.Bxe7 Qxe7 Black is definitely not worse 16...Nxe7 17.Bxh7+! is what White was hoping for 16.Qc1 Now there are some ideas of Bxe7 and Qh6 with an attack f6? After this Black's position collapses 16...c4 with the idea of bringing the knight to c5 was an idea 17.Ne4 White is probably a bit better but it's far from decisive 17.exf6 Bxf6 17...N5xf6 18.Rxe6 is also winning a pawn 18.Rxe6 Bxg5 19.Qxg5 Black must have been relying on two ideas: ..Nf4 or ..Rxf3 but the complications work in White's favor Rxf3? 19...Nf4? 20.Re7 Bxf3 21.Qh6 Rf7 22.Rxf7 Kxf7 23.Qxh7+ Kf8 24.gxf3+- 20.Bxg6! 20.gxf3? Nf4 White is still winning but this is completely unnecessary 20...Rxg3 20...Rf6 21.Be8+! Kf8 22.Bxd7 and White regains the piece 21.fxg3 21.Bxh7+ Kf7 22.Qf5+ N7f6 23.fxg3 was also winning but White goes for the safer option 21...N7f6 is pretty much forced otherwise Black is getting mated 22.Rxf6 Nxf6 23.Be4+ Kf7 24.Rf1 Rd6 24...Bxe4?? 25.Rxf6+ with mate 25.Qe5! The threat of Rxf6 forces Black to give up material Qe7 25...Bxe4? 26.Rxf6+ Rxf6 27.Qxc7+ 26.Qxe7+ Kxe7 27.Bxb7 Rd2 28.Rb1 28.Bxa6?! Rxb2 just complicates things 28...a5 If White is not careful, the active rook can give Black some serious drawing chances 29.Bf3 The idea is simple: Re1+ followed by Re2 securing the second rank for the White king b4 30.cxb4 30.Re1+ Kd6 31.Re2? Rxe2 32.Bxe2 bxc3 33.bxc3 Ne4= 30...axb4 31.Re1+ Kf7?! This makes White's job easy 31...Kd6 32.Rd1 Rxd1+ 33.Bxd1 c4 34.Kf2 Nd5 35.g4 is still winning for White but requires some more effort 32.Re2 Rd1+ 33.Kf2 Now the king is cut off from the e-file and White can start advancing his extra pawns Ra1 34.b3 Rc1 35.g4 h6 36.Kg3 Rc3 37.Kf4 Kg6 Otherwise White gets rid of the doubled pawn with g5 38.Re6 Kf7 39.Rc6 Ke7 40.Kf5 Ng8 41.Rg6 Kf8 42.Ra6 Rd3 43.Kg6 Rd8 44.Ra8 Rxa8 45.Bxa8 Ke7 46.Kg7 Nf6 47.Bf3 Ke6 48.Kxh6 Nd7 49.g5 Ne5 50.g6 Kf6 51.Be4 Ng4+ 52.Kh7 Ke5 53.Bb1 1–0

IM Awonder Liang of the USA is the top rated player in the world
born in or after 2003. (Photo: Oren Eliezer)

As you can see from the annotated games above, Sheng defeated Li and Patel defeated Liang. As a result of these upsets four players tied for first place. The first tie-break was head to head competition. After some discussion it was determined this tie-break didn’t “break the tie.” Since all players in the four-way tie had not played each other, this tie-break became moot.  The second tie-break was the modified Buchholz. On the second tie-break Li won first, Sheng finished second, Chandra won third, and Petal finished fourth. Li won gold and made a GM norm. Sheng won silver and became an IM. Chandra won bronze.

The results of this tournament demonstrate that the competition among young chess players in the United States is so fierce that two of the world’s top players for their group lost to lesser known up and coming players in the final round who are also from the United States. Congratulations to all who competed in this wonderful event.
