Opera Euro Rapid: Nakamura eliminated, Dubov to face Carlsen

by Carlos Alberto Colodro
2/9/2021 – One of the pre-tournament favourites, online blitz specialist Hikaru Nakamura, did not make it into the knockout stage of the Opera Rapid tournament after failing to convert a winning position in the last round against Sam Shankland. Nakamura was eliminated on tiebreak criteria, as he got the same score as Daniil Dubov but won fewer games than the Russian. Ian Nepomniachtchi also had a tough day at the office and was eliminated.

On to the quarterfinals

When you see the final standings of a 16-player round-robin tournament and notice that Ding Liren is the participant sitting at the bottom of the table you know it was a strong event. Only half of the players moved on to the knockout stage, with some big names leaving the competition after three days of action — besides Ding, Hikaru Nakamura, Ian Nepomniachtchi and Alexander Grischuk were also eliminated.

Perhaps the most surprising elimination was Nakamura’s, though, as he has shown excellent results in online tournaments during the pandemic and is still the number one ranked player in the blitz ratings list.

Furthermore, it seemed like things were going his way after he scored a key victory over Matthias Bluebaum in the penultimate round and had a winning position against Sam Shankland in round 15. Suddenly, however, things took a turn for the worse, as he not only gave up his advantage but ended up losing the last game of the preliminaries.

This meant he had finished the with a fifty-percent 7½/15 score and needed Grischuk to beat Daniil Dubov to make it into the knockout. In the end, Dubov drew his compatriot and only qualified thanks to the tournament’s tiebreak criteria — he scored as many points as Nakamura but collected a larger number of wins.

The top of the table

Meanwhile, in the fight for first place, Magnus Carlsen did not have a great day as he beat Vidit and lost to Ding for a 2½/5 score. Anish Giri, who defeated Bluebaum and drew his remaining four games on Monday, caught up with him in the end — however, the Dutchman finished second on the same tiebreak criterion that left Nakamura out of contention.

With Carlsen winning the round robin and Dubov barely making it into the quarterfinals, perhaps one of the most exciting pairings will be seen in the first round of the knockout. Let us not forget that Dubov knocked out Carlsen in the first stage of the knockout at the Airthings Masters. The ever-fighting Russian told Kaja Snare:

For me, it will be great fun. He’s still my favourite opponent, so I’m obviously very happy to play him again. So it’s once again the same story, I repeat the same thing — I don’t care about the result playing Magnus, he’s human, blah, blah, blah (smiles).

The remaining pairings will see Giri facing Teimour Radjabov, who was the only player to finish the preliminaries undefeated, as he won one and drew his remaining fourteen games to get seventh place; Levon Aronian will play his friend Maxime Vachier-Lagrave after both players scored 8½ points; and Wesley So will face Jan-Krzysztof Duda, who collected 3 points on Monday to join the top half of the standings table — the Polish star’s ascent included a thrilling victory over Dubov in round 13.

Duda and Dubov make it fun

A highlight of the day was the encounter between two of the most daring players of the circuit. Duda had the white pieces and went for it from the start:

 
Duda vs. Dubov
Position after 13...Be7

14.Nxe6 fxe6 15.Qh5+ and Black needs to hold tight but is already a piece up. There followed 15...g6 16.Bxg6+ hxg6 17.Qxg6+ (not 17.Qxh8+ Nf8, when Black keeps things under control) 17...Kf8 18.Bh6+ Rxh6 19.Qxh6+

 
Position after 19.Qxh6+

The black king is exposed, but White has given up all his minor pieces — he needs more ammunition to continue the attack.

Dubov, who is known for being a fearless attacker, found ways to deal with his opponent’s initiative in the ensuing complications. In fact, the engines evaluated the position as equal for quite a while, until the Russian erred on move 32:

 
Position after 32...Nf6

32...Nf6+ was a mistake as it allowed the good-looking 33.Qxg8+ and White gets a new queen — 33...Nxg8 34.e8Q

Duda had a winning position, but Black eventually got two passed pawns on the queenside, forcing his opponent to play carefully while trying to make the most of his advantage. Duda did not calculate precisely and faltered on move 44:

 
Position after 43...cxb3

It was tough to decide against 44.Qxa6, but 44.Rf4 was the right way forward, creating a number of threats connected to e8 or Rg4+. After Duda’s choice, though, the engines again considered the position to be equal. White eventually exchanged his rook for Black’s two minor pieces and entered a queen endgame three pawns to the good. Dubov was the one who made the last mistake, however:

 
Position after 48.f3

Black could have ended the game with 48...Qc2+ 49.Kh3 Qh7+ and the king cannot escape the checks. Instead, Dubov played 48...b1Q and lost the game eight moves later. 

GM Karsten Müller took a deeper look at the endgame with four queens on the board!

But even this has exceptions: b1Q? Black queens too early. 48...Qc2+ draws due to 49.Kh3 Qh7+ 50.Kg2 50.Kg4?

Instructive analyses by Karsten Müller

Our in-house endgame specialist not only looked at the final stage of the spectacular game above, but also analysed a couple of endgames played by world champion Magnus Carlsen — one in which he used an outside passed pawn to get the better of Vidit, and one in which he survived against Dubov in and endgame with a pair of bishops against a rook.

Now the blockade of the b-pawn can be broken. 36.f4?! 36.f3 is more tenacious, but also does not help due to Bc8 37.Kf2 Be6 38.Bxe6 Kxe6 39.Nc4 39.Ke2 Kd5 40.Kd2 g5 41.Kc2 g4-+ 39...Kd5 40.Nd2 b3 41.Ke2 Kc6 42.Nb1 Kb5 43.Kd2 Kc4 44.Na3+ Kb4 45.Nb1 h5 46.h3 Ne6 47.e4 f4 48.gxf4 Nxf4 49.e5 Kc4 50.Ke3 Nd5+ 51.Kf2 b2-+ 36...Bb5? This just wastes a valuable tempo. The direct 36...Bc8 37.Kf2 Be6 wins, e.g. 38.Bxe6 Kxe6 39.Ke2 Kd5 40.Kd2 b3 41.Kc3 Ke4 42.Nc4 Kf3 43.Kb4 Ne4 44.Kxb3 Kg2 45.Ne5 Kxh2 46.g4 fxg4 47.Nxg4+ Kg3 48.Nh6 Kf3 49.f5 g5-+ 37.Kf2 Bd7 38.e4? Vidit violates the "do not rush" endgame principle. 38.Ke2 draws, e.g. Be6 39.Bc6 Ke7 40.Nb7 Nxb7 41.Bxb7 Kd6 42.Kd3 Bd5 43.Ba6 Kc5 44.Kc2 Bc4 45.Bb7= 38...fxe4 39.Ke3 Be6 40.Bxe6 After 40.Bxe4 Nxe4 41.Kxe4 b3 a typical scenario arises. The outside passed pawn forces the defending king to leave the kingside and then Black's king can invade: 42.Kd3 Kf5! 43.h3 b2 44.Kc2 Ke4 45.Kxb2 Kf3 46.g4 Kxf4 47.Nc6 Kg3 48.Kc3 Kxh3 49.g5 Kg4-+ 40...Kxe6 41.Kd4 b3 42.Nc4 42.Kxc5 b2-+ 42...Na4 42...Na4 43.Kxe4 b2 44.Nd2 Nc3+ 45.Kd3 b1Q+ 46.Nxb1 Nxb1-+ 0–1
