Durarbayli endures in St. Louis Summer Classic

by Macauley Peterson
5/25/2018 – Vasif Durarbayli doubled up Varuzhan Akobian in a rapid tiebreak for first place in the top 'A' group of the St. Louis Summer Classic, winning both playoff games and earning $6,000. Both players finished the classical tournament with 6.0 / 9, a half point ahead of third-place finisher, Sam Sevian. GM Daniel Fernandez looks at the ninth round games. There was also a 'B' tournament, but one with far less drama at the end, as top seed Kamil Dragun took a quick draw to clinch clear first a full point ahead of Andrey Stukopin | Photo: Saint Louis Chess Club on YouTube

Americans come up empty

A pair of ten-player tournaments for the St. Louis Summer Classic were played May 15th to 23rd. The 'A' tournament players had an average rating of 2627, while the 'B' tournament featured a slightly weaker field with a rating average of 2534. The prize fund was USD $36,000 ($22,000 for the A and $14,000 for the B tournaments).

In the 'A' tournament, Vasif Durarbayli and Varuzhan Akobian were tied on 5½ points after eight rounds, but 17-year-old GM Sam Sevian was just a half point behind and playing the Azerbaijani leader. The trio had a sizeable lead on the rest of the field.

Akobian, who was born in Yerevan, immigrated to the USA in 2001, when he was Sevian's age. Sam was born in Corning, New York, as a first-generation American — both his parents came over from Armenia.

Durarbayli has just wrapped up his studies at Webster University in St. Louis, where he studied economics and finance since 2014, earning both a BA and a Master's degree. He's preparing to return to Azerbaijan, where national tensions with anything related to Armenia tend to run high. It's a bit tangential to the tournament, but the political undertones will certainly be noticed by chess fans in the two countries as well as the extensive Armenian diaspora.

The key question in the final round in St. Louis, however, was whether Sevian could somehow win with black, and come equal first with Akobian, who drew his white game against Daniel Fridman quite quickly and easily.

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d3 d6 5.0-0 g6 6.c4 It is well worth asking why this line exists. Surely White wasn't hoping for a structure with Bxc6 and a Closed-Sicilian or Exchange-Ruy like clamp with lots of pawns on light squares? 6.d4 is the main move, even having lost one tempo. Bd7 7.d5 Ne7 8.Bxd7+ Qxd7 9.Re1 Bg7 10.c4 0-0 11.Nc3 and both sides have more or less what they were looking for. 6...Bg7 7.Nc3 0-0 8.Be3 So we have our answer. At the first moment when the option was serious, White chose not to take on c6. 8.Bxc6 bxc6 looks interesting until we realise that Black wants to play with ...c5 and that he will additionally have time for any space-gaining or reorganising moves that he needs, like ...Nd7-b8-c6-d4 or ... f5-f4. 8...Ng4 9.Bg5 f6 10.Bd2 f5 I wonder how much inspiration the players were drawing from the game Prohaszka-Zherebukh at this moment? 10...Nd4 was a slightly better choice, not giving White the chance to take decisive strategic action himself in the centre. 11.Bg5 11.c5!? makes Black's opening triumph look quite a bit more ambiguous 11.h3 Nf6 12.Bxc6 bxc6 13.b4 is the engine recommendation, and after f4 we get a standard race for play on opposite wings. 11...Nf6 Black drifts over the next few moves. 11...Bf6! was the most principled decision. 12.Bd2 f4! and the race continues 12.Nd5 12.c5!? is again an interesting call, although White made it soon enough. 12...fxe4 13.dxe4 Bg4 13...a6 14.Bxc6 bxc6 15.Nxf6+ Bxf6 would have been an interesting call for Black, which he probably rejected in view of 16.Bxf6 Qxf6 17.c5 14.c5? This is clearly a miscalculation of some kind, because Black now obtains a monster knight. 14.Bxc6 bxc6 15.Ne3 Bxf3 16.Qxf3 Qb8!= and Black has to play a few more accurate moves in order to hold equality with the worse minor pieces 14...Bxf3! 15.Qxf3 Nd4 Black has clearly won the opening battle. 16.Qd3 16.Qe3!? The computer suggests some downright confusing moves sometimes. From my perspective, this gains nothing after Black plays Kh8 when he will be threatening the b5-bishop for real. 16...c6 17.Nxf6+ Bxf6 18.Bc4+ Kg7 19.Bxf6+ Qxf6 20.cxd6 Qxd6 21.Rad1 Rad8 22.a3 g5 23.Qe3 Qg6 24.f3 Rf4 25.Rd2 h5 25...b5 26.Ba2 g4 clarifies the situation more 26.Rdf2 Rdf8 Somewhere around here, Black's control of the game starts to slip. 26...b5 27.Ba2 a5 27.b4 Qh6 28.a4 Qd6?! 29.b5 29.g3 and now presumably Black's idea was to retreat his pieces and prepare ...g4, when he can use the f3-square, however there isn't time. Qg6 30.Kh1 R4f6 31.f4! 29...Qc5 30.Bd3 Kh7 Black once more looks like he is controlling the game but bishops often demonstrate a remarkable propensity for playing 'around' opponents' pieces. 31.bxc6 bxc6 32.Kh1 Qe7 33.g3 R4f7 34.f4! The correct idea to break out of the bind. Black now has to think hard about the possibility of being worse. gxf4 35.gxf4 Qh4! 36.Qg3! Ensuring that at least White won't lose. Qxg3 37.hxg3 Rg7 38.Rg2 h4! Black in his turn ensures that he won't lose! 39.gxh4 Rxg2 40.Kxg2 exf4 41.Kh3 Kh6 42.e5 f3 43.Rg1 f2 44.Rg6+ Kh5 45.Rf6 Rxf6 46.exf6 f1Q+ 47.Bxf1 Kg6= The draw is now totally ensured. 48.Kg4 Kxf6 49.Bc4 Nf5 50.Ba6 Nd4 51.Kh5 Ne6 52.Bc4 Ng7+ 53.Kg4 Nf5 54.Bd3 Nd6 55.Kh5 Kg7 56.Kg5 Nb7 57.h5 Nc5 58.Bc2 a5 59.h6+ Kh8 60.Kf6 Nd7+ 61.Kf7 Nc5 62.Kg6 Kg8 63.Kf6 Kh8 64.Kg6 Kg8 65.Kf5 Kh7 66.Kg5+ Kg8 67.Kg6 Kh8 68.h7 Nxa4 69.Bxa4 c5 70.Bb3 c4 71.Bxc4 a4 72.Bd5 a3 73.Ba2 ½–½

Vasif Durarbayli and Sam Sevian

The draw left the standings at the top unchanged, forcing a playoff. The tie-breaking match of two games was played at a rate of ten minutes plus two seconds delay (not increment) for each player.

Durarbayli got a huge boost from the first game when he managed to win with the black pieces. In an equal knight ending, Durarbayli had a huge time advantage and Akobian cracked in a critical moment.

Move the pieces on the live diagram

White can just sit tight with 44.Nf1, but with just 17 seconds remaining Akobian went for the aggressive 44.e6 Nxe6 45.Nxh5. It took Durarbayli only eight seconds to find the winning plan 45...Nd4+ 46.Kb1 b3!

Now suddenly 47.axb3 Kxb3 threatens a2+ and if Ka1, then Nc2 is mate! Akobian's 47.Ng3 aims to guard the e2 square to prevent a Nd4-e2-c3 manoever, but 47...b2 48.h5 Nb5 49.Ne2 Kd3 brought the game to an abrupt end as white's h-pawn is too far from queening to pose a problem.

Illegal move incident

In the second rapid game, Akobian missed some chances in the early middlegame, after gaining two minor pieces for a rook, but by move 60 the pair had reached an even endgame, with both sides down to just a few seconds remaining on their clocks. Anything could happen, and something unusual did — Akobian played an illegal move:

Durarbayli had just taken a pawn with his knight on d3, and in this position, Akobian overlooked that his king on f4 was in check and played his knight to g1.

Position after 60.Nxd3+

The situation was slightly complicated by the fact that Durarbayli did not immediately spot the illegality and moved his rook to f8 before noticing the problem and stopping the clock to summon the arbiter. After a brief discussion, the game was restarted after white's 60th move, with two minutes added to Durarbayli's clock. Now, with such a huge time deficit, Akobian quickly blundered. 60...Bxd3 61.Kxd3 b4? 62.Re4+ and given the fact that Black was lost and also in a must-win situation in the playoff, Akobian resigned the game.

Durarbayli has one more tournament on his agenda — the Chicago Open this weekend — and then plans to take the summer off with his family back home. With any luck in Chicago, he'll be returning home at a new career peak Elo rating, approaching 2650, and moving up to number seven in Azerbaijan.

Position not in LiveBook
1.Nf3 c5 2.c4 Nc6 3.d4 cxd4 4.Nxd4 An alternative way to try and get Maroczy-type positions with White (i.e. not an Open Sicilian.) Black has a slightly wider variety of options, but as White has not yet completely committed his centre, the worst-cases outcomes for him are not as bad and the position is thus marginally more peaceful. Nf6 4...Qb6 makes more sense here than after 1.e4, though it is still known there (the Grivas system.) 5.Nb3 e6 6.Nc3 Nf6 7.a3! White must tread a narrow path to an edge. 7.e4 Bb4 8.Bd3 Ne5 9.0-0 Qd6! With the queens gone Black equalised quickly in Mareco,S-Alekseev,E Zuerich 2013. 7...d5 8.Be3 8.cxd5 is markedly inferior: the pawn cannot be taken at the end due to ...Be6 so after Nxd5 9.Nxd5 exd5 White should probably play 10.Be3 d4 11.Nxd4 Qxb2 12.Nxc6 Qc3+ 13.Bd2 Qxc6= where Black has at least equalised. 8...Qd8 9.cxd5 Nxd5 10.Nxd5 exd5 11.g3 Be7 12.Bg2 Bf6! 13.0-0! This has only been played once, but it is the most accurate, refusing to compromise the blockade of d4 due to Black's tempo-gainer. After 13.Qd2 either 0-0 or indeed the pawn sacrifice 13...d4 of Speelman-Sax is playable. 13...Bxb2 13...0-0 14.Qxd5 Qxd5 15.Bxd5 Bxb2 16.Ra2 Bf6 17.Nc5 14.Ra2 Bf6 15.Rd2 0-0 16.Rxd5 Qc7 17.Bf4 Qb6 18.Nc5 Re8 19.Qd3 Can,E-Kosic,D Sarajevo 2016 After 4...g6 White should probably transpose into the Accelerated Dragon. 5.e4 Bg7 6.Be3 5.Nc3 e6 6.a3 Not played particularly often, but maybe White realised that the standard moves were not promising anything. 6.e4 is possible, but as shown in previous analysis on this site (the game Kapnisis-Pogosyan, Heraklion 2018) Black shouldn't be too worried after Bb4 7.Nxc6 dxc6 8.Qxd8+ Kxd8 , and this isn't even his only way of playing. 6.g3 is the main line: Qb6! By contrast to 4...Qb6, here White hasn't been able to play a3 thanks to the move order, so Black gets a better version. 7.Nb3 Ne5! Threatening ...Nxc4 and ...Qc6. 8.e4 Bb4 9.Qe2 d6 10.f4 Nc6= Black has equalised due to White's dodgy structure. 10...Ned7!? 6.Ndb5 d5! Black equalises reasonably straightforwardly after this pawn sacrifice. 7.cxd5 7.Bf4 e5 8.cxd5 exf4 9.dxc6 bxc6 10.Qxd8+ Kxd8 Black is fine, as I realised soon in Fernandez,D-Sax,G Kecskemet 2013, where I managed to draw with my illustrious opponent. 7...Nxd5 8.Nxd5 exd5 9.Qxd5 Bb4+ This position has been analysed to death, but the long and short of it is that Black is fine. 6...d5 6...Bc5!? is more commonly played, and it's quite interesting to see how many extra options Black gets compared to a 'standard' Maroczy position. 7.Nb3 7.Ndb5 0-0! 8.Bf4 e5 9.Bg3 d6 10.b4? a6 7...Bb6 8.e4 8.g3 d5 9.cxd5 exd5 10.Bg2 d4 11.Na4 0-0 Black's play continues along Tarrasch lines. 8...d5! An interesting pawn sacrifice. The details probably deserve a whole review in CBM, but let me just say for now that 9.cxd5 exd5 10.exd5 Ng4! 11.Be3 Nxe3 12.fxe3 Ne5 gives Black at least enough for the pawn. 7.cxd5 exd5 Black has maybe made a slightly substandard decision in going into the Tarrasch structure without White making any special concessions, but I would still hesitate to call this an opening edge for White. 8.e3 8.g3 Bc5 9.Be3 looks most critical, and here there is a game from one of the greatest '...e6 Sicilian theoreticians' Evgeny Alekseev. Bb6 10.Bg2 0-0 11.0-0 Re8 12.h3 Be6 12...Rxe3!? 13.Na4 Bxd4 14.Bxd4 Ne4= Malakhov,V-Alekseev,E St Petersburg 2015 8...Bd6 9.Bb5 Bd7 10.Nf3 White tries to obtain a '1.b3-type' position with some extra tempi. Unfortunately for him this doesn't promise an edge either. Be6 11.b3 0-0 12.Bb2 a6 13.Be2 Rc8 14.0-0 So we have arrived. Both sides have essentially completed development. White's plans all include simply bolstering the d4-square repeatedly, whereas Black has greater variety: he can play for a kingside attack, or for ...b5-b4, or maybe even ...d4 in some cases. Bb8 Making Black's intentions clear. He would like ...Qd6, ...Rfd8 if necessary, .. .Bg4 and ...Ne4. 14...b5 is interesting, if only because it's not clear what White's next move could be. The engine comes up with the very strange 15.Na2 Qe7 16.Nb4 Nxb4 17.axb4 Rc6 when Black will almost certainly take a pawn but White has compensation. 15.Rc1 Qd6 16.Na4 Ne4 17.b4 Bg4 18.g3 Bh3 It isn't completely clear that the bishop improves its prospects on h3; indeed it cues up a possible Nd3-f4 jump for White. 18...Ba7 immediately was marginally better. 19.Re1 Ba7!? Black protects against Nc5, and vaguely hints that one day he might like to play ...d4. Black doesn't have an ideal move anymore; both this and my alternative leave White a little something. 19...Rfd8 20.Nc5 Qe7 is the engine suggestion, but here White can probably take advantage of the exposed bishop on h3: 21.Nd3! whereupon the beast wants to head back to g4, proclaiming '0.17' but this is a good sign that things have not proceeded ideally for Black. 20.Nc3?! 20.Nd2! was the correct move in my opinion, trading off Black's e4-knight for the less useful of the Black knights. f5 21.Nc5!? 21.Nxe4 fxe4 22.Nc5 21...Nxc5 22.bxc5 Bxc5 23.Qb3 White has amazing compensation. 20...Qh6!? Black sets up ...Nxf2. This is an intuitive pawn sacrifice, and probably a good one. 21.Nxe4 It is impossible to criticise this most natural decision; White is likely not worse after it. However there was a better move. 21.Nxd5!? was playable but it took some nerves, as well as some incredible engine-level calculation. Rcd8! 21...Rfd8?! looks desirable but the engine points out the amazing tactic 22.Bxa6‼ taking a second pawn and leaving Black in trouble. Qh5 22...bxa6 23.Rxc6 Qxc6 24.Ne7+ Kf8 25.Qxd8+ Rxd8 26.Nxc6 Rc8 27.Rc1!+- 23.Bxb7 Rxd5 24.Nd4! Nxd4 25.Rxc8+ Bxc8 26.Qxh5 Rxh5 27.Bxe4± White has three pawns for the piece and Black's co-ordination is miserable. 22.Bxa6! Nxb4‼ 22...Nxf2 23.Kxf2 Rfe8 looks reasonably scary from a human perspective, but the engine is fine to play 24.Bxb7! Rxd5 25.Bd4± 23.axb4 23.Bxb7 Nxd5 24.Bxd5 Nxf2 25.Kxf2 Be6 and White is in serious trouble 23...Qxa6 24.Qc2! Rxd5 25.Qxe4 White emerges a pawn up, and Black has some compensation but it is not enough. 21...dxe4 22.Nd2 22.Nd4 Rcd8 23.Rc2 Nxd4 24.Bxd4 Bxd4 25.exd4 Rd6 is a bad structure to sign up for in principle, even if White is somehow still essentially fine here. 22.Ne5! was best, exchanging off Black's attacking pieces before they become too threatening. Rfd8 22...Bxe3 23.Nxc6!+- 23.Rxc6!? bxc6 24.Qc2 Bxe3 24...Bb8 25.Qxe4 25.Qxe4 Bb6 26.Bxa6 White obtains two pawns for the exchange and is basically fine. 22...Rcd8! Now, however, White gets badly tied down and his position gets broken open by the two battering-rams on the f-file. 23.Rc2 f5 24.Qc1 f4! 25.exf4 e3! 26.Bc4+ 26.Ne4 exf2+ 27.Nxf2 Nd4 was in principle legal, but I suspect Black's attack is enough to make him better here too. 26.fxe3 Rxf4 26...Kh8 27.Rxe3 27.fxe3 Rxf4 is again crushing. 27...Bxe3 28.fxe3 Rd7 In what follows White obtains a few chances to get back into the game, but the momentum remains firmly with Black. 28...Bg4!? 29.Be2 29.Nf3 might once again equalise the game by blockading on the d-file. 29...Qe6 30.Nf3 h6 31.Kf2 Bf5 32.Rc5 32.Rd2!?= 32...Be4 Now the intention is clearly ...Qh3. 33.Ne5?! 33.Rh5!= 33...Nxe5? 33...Qh3! 34.Nxd7 Qxh2+ 35.Ke1 Qxg3+ 36.Kd2 Rd8 is close to winning. 34.Rxe5 Qh3 35.Qg1? An odd winning attempt. 35.Rxe4 Qxh2+ 36.Kf3 was possible, and Black only has a draw. Maybe the time-trouble was so desperate that White thought ...Qh1 wins? 35...Rd2! Once the bishop on e2 falls, White can expect to be mated. 36.Bc1 Rxe2+! 37.Kxe2 Qg4+ 38.Kd2 Rd8+ 39.Kc3 Qe2 A topsy-turvy game, but ultimately Black simply played better and with more energy. 0–1

Dragun's smooth sailing

The 'B' tournament was won handily by Kamil Dragun, from Poland. Dragun has also been studying in the USA, at UTRGV in Brownsville, Texas. As number eleven nationally, he would have been eligible for the recent Polish Championship won by Jan-Krzysztof Duda. Instead, he blazed through the field in St. Louis, starting with two wins and adding two more for an undefeated 6½ / 9.

The diverse international field left the two players for the host country, Josh Friedel and Tatev Abrahamyan far down the table.
