The first mini-matches of the Opera Euro Rapid knockout stage were played on Tuesday. Each confrontation consists of two 4-game mini-matches, and in case of a tie a blitz playoff will follow immediately after the second ‘set’.
Magnus Carlsen was the first one to score a mini-match victory, as he took down Daniil Dubov — who had knocked him out of the Airthings Masters a bit over a month ago — after winning two out of their three first encounters. Maxime Vachier-Lagrave and Wesley So obtained 2½:1½ wins over Levon Aronian and Jan-Krzysztof Duda respectively, while Anish Giri managed to win game 4 on demand to tie the score with Teimour Radjabov.

The world champion was ruthless on day 1 of his quarterfinal match against Daniil Dubov. Carlsen kicked off with a win.
21.Qb3 Qd7 22.Nf5 Threatens to capture on d4 and then play Qc4.
22...Ng4? [22...Nh5!? with the idea 23.N5xd4 exd4 24.e5 Nf4 25.Re4 Qf7 26.Qd1 Qg6 getting counterplaY.]
23.N5xd4 exd4 24.e5 The knight on g4 is in trouble.

30.Qe2 White has to be careful once more. He should not let the queen to capture on f3.

32...Qxb5 33.Re1 Nxd3 34.Rd1 1–0
After a draw in the second game, Carlsen also won the third game and thus ended the mini-match earlier than expected.
Master Class Vol.8: Magnus Carlsen
Scarcely any world champion has managed to captivate chess lovers to the extent Carlsen has. The enormously talented Norwegian hasn't been systematically trained within the structures of a major chess-playing nation such as Russia, the Ukraine or China.

After a draw in the first game, Wesley So made a big mistake against Jan-Krzystof in the second game and fell behind on the scoreboard. GM Karsten Müller analysed the materially-imbalanced endgame.
With two wins in games 3 and 4, however, the American grandmaster turned the tables around and won the first set of the match.
In the third game, So needed 103 moves to win the endgame. Here is Karsten Müller's analysis.
A queen and bishop attack put an end to the fourth game:
27...Rd2+ 28.Bxd2 [28.Kf1 Rc2] 28...Qxd2+ 29.Kf1 Qxe3 30.Qe4 Qc1+ 31.Kg2 Qg5+ 32.Qg4 Qd2+ 33.Kh3 gxf5 34.Qh5 [34.Bxf5 Rg8] 34...Be5 35.f4 Qxf4 0–1
In the match between Maxime Vachier-Lagrave and Levon Aronian the first game also ended without a winner. Then, in the second game, the French star demonstrated the explosive power of piece play in the Grünfeld Defence with the black pieces in a display of tactical fireworks. Aronian was literally overrun.

In the next game Aronian was about to equalize, but after a mistake Maxime Vachier-Lagrave managed to escape with a draw.
In the match between Anish Giri and Teimour Radjabov, the Azerbaijani took the lead with a win in the third game, but Giri bounced back and equalized in the fourth game.
Karsten Müller took a look at the deadly zugzwang that gave Radjabov his win of the day.
