Magnus Carlsen’s unflagging energy continues to bear good results in the era of online tournaments. The world champion has played almost nonstop since the pandemic forced organizers to set up online events for the world’s elite, and has consistently fought for first place in all events no matter the format.
After ending day one on an even score, beating Hikaru Nakamura and losing due to a disconnect to Ian Nepomniachtchi, the world champion scored a perfect 6 out of 6 on Wednesday, winning all three of his games each worth two points for the overall standings. Carlsen beat Levon Aronian, Leinier Dominguez and Pentala Harikrishna to take the sole lead.
Wesley So and Nepomniachtchi had grabbed the lead after winning in round 4, and finished the day sharing second place a point behind Carlsen — while So drew his last two games on Wednesday, Nepomniachtchi lost to Jeffery Xiong and defeated Hikaru Nakamura to remain in the fight for first place.

No points were split in round 4, as then co-leaders Aronian and Harikrishna lost their games and allowed So and Nepomniachtchi to climb to first place. Aronian’s creative handling of the Grünfeld Defence was no match to Carlsen’s straightforward play in the centre of the board:
The Grünfeld Defence was invented by the famous Austrian Grandmaster Ernst Grünfeld in the early twenties of the last century. One of the first reactions to it came from the great Akiba Rubinstein - the g3 system, fianchettoing the bishop to g2. After that many systems were tried to refute the Grünfeld and nothing really worked. So, Rubinstein's recipe remains a very important positional approach against this dynamic opening.
The world champion converted his positional trumps into a tangible edge with 14.Bxh6 Bxh6 15.Bxf5 gxf5 16.0-0 e6 17.dxe6 Nc5 18.exf7+ Rxf7 19.Qa3 — Black is a pawn down and has weakened his king’s position. Aronian resigned on move 34.
Meanwhile, Harikrishna was trying to defend a materially-balanced position in which Nepomniachtchi, playing black, had a strong passer on the d-file:
White’s 38.Qe4 was the losing move, as Nepomniachtchi now had 38...Rc3, and after 39.Re8+ Rxe8 40.Qxe8+ Kg7 41.Qe2 Rc1 there is no defence for White:
42.Nxd2 Rxd1+ 43.Qxd1 Qd4 and the knight is lost. Harikrishna resigned two moves later.
Alexander Grischuk also won with the black pieces, taking down Xiong in a complex struggle. So and Nakamura, on the other hand, won with white, defeating Leinier Dominguez and Alireza Firouzja respectively.
While he thought his remaining two wins were rather lucky, Carlsen was happy with his victory over Dominguez in round 5. Out of a sharp Philidor Defence, the world champion correctly gave up an exchange in the middlegame:
A Sicilian Stunner - The Kalashnikov
This increasingly popular opening is easy to pick up as the Black pieces can usually be developed quickly and smoothly. Many of the ideas are thematic and Black can achieve attacking positions in several of the variations.
Black chose to keep his dark-squared bishop alive by capturing with the rook — 30...Rxe5 31.Nxe5 Bxe5. Six moves later, the well-placed bishop was key in allowing Carlsen to execute a beautiful tactical shot:
37...Rxb2+ 38.Kxb2 d3+, opening up the diagonal, 39.Kc1 Qc5+ 40.Kd2 Qc2+ 41.Ke1 Bh4+ (again, the bishop) and Dominguez resigned.
Earlier in the round, then co-leader Nepomniachtchi lost in barely 21 moves against Xiong. The Russian star badly miscalculated as early as move 10:
White’s greedy 10.Qxb7 was duly punished by the American youngster. It all started with 10...Ndb4 11.Bb5 Nxc2+ 12.Ke2 0-0 13.Bxc6 Rb8 and White could not survive such a grave disadvantage in development.
The three remaining games finished drawn.
True to his style, Nepomniachtchi did not shy away from entering a sharp battle after his quick loss with the white pieces. He was facing a hungry-for-points Nakamura, who gave up no fewer than three pawns in order to keep the initiative:
The interactive format encourages the viewer to study and find the brilliancy, following the footsteps of some of the greatest players of the game.
29.Nd4 is a good-looking move, but it is also a mistake, as Black now has 29...Qe4. After 30.Rf4, Nepomniachtchi correctly assessed that 30...Qxf4 31.Qxf4 Bxd4+ 32.Rxd4 cxd4 gives him a comfortable edge with the pair of rooks and the extra pawns against the queen.
Notice that only 29...Qe4 wins for Black, with other sharp lines favouring White — for example, 29...Bxd4 30.Rxd4 Nf5 31.Rxf5 and White is ready to set up a battery on the h-file.
Carlsen beat Harikrishna with white in 31 moves after the latter miscalculated in a complex position, while Firouzja strangely lost on time against Dominguez. So v Grischuk and Xiong v Aronian were rather uneventful draws.
