Magnus tweets on Nihal-Dardha game

The PBG Alaskan Knights have won all five of their matches so far which means they have managed to beat every single team participating in this edition. However, this might change tomorrow. Why? Because Nihal Sarin made a draw claim with two seconds left on the clock. An arbiter was called to the board. Dardha accepted. But wait, that's not the end.

American Gambits - Ganges Grandmasters: 3-0 (10-4)

The first result of the match occurred in the game between IM Bibisara Assaubayeva and GM R Vaishali. The game ended in a draw. It is also the first scoring game for Vaishali at this event. Jan-Krzysztof Duda drew next with Arjun Erigaisi. Hikaru Nakamura scored the first win of the match on the 'Icon' board, against Vishy Anand. Parham Maghsoodloo made an insane save against Yangyi Yu. GM Elisabeth Paehtz (AG) defeated IM Nurgyul Salimova (GG).

This DVD allows you to learn from the example of one of the best players in the history of chess and from the explanations of the authors how to successfully organise your games strategically, and how to keep your opponent permanently under pressure.

The maestro allowed 31.Nc6 Rxc6 32.Rxd6 Rcxd6. It is certainly a good option, however without increment it became incredibly difficult to defend, and eventually he ran out of time.

Hikaru Nakamura bounced back well after yesterday's loss against Alireza Firouzja

Jan-Krzysztof Duda had a well contested draw against Arjun Erigaisi

59.c7?? abandoned all hopes for White to win the game. 59.Qd8+ or Qd4+ would have maintained White's decisive advantage. 59.c7?? fell into a perpetual check where Black could afford losing the e4-pawn. Maghsoodloo managed to save the game when he was down to his last few seconds on the clock.

Parham Maghsoodloo redeemed his loss yesterday, although it could not save the team defeat

Alpine SG Pipers - PBG Alaskan Knights: 0-3 (7-9)

Anish Giri (PBG AK) made a paltry mistake and lost his knight in just a one-move tactic against Magnus Carlsen (ASGP). Shakhriyar Mamedyarov (PBG AK) drew with Richard Rapport (ASGP). Nodirbek Abdusattorov (PBG AK) defeated R Praggnanandhaa (ASGP) convincingly. Zhongyi Tan (PBG AK) overlooked a mate in one. However, she still managed to beat Yifan Hou. IM Alina Kashlinskaya (PBG AK) drew with GM Kateryna Lagno (ASGP). Nihal Sarin drew with Daniel Dardha and the team won the match.

21.Rxd4?? Rxc3 23.Qxb8 Rxb8 and White resigned as he cannot recover the lost material. White needed to trade the queens first with 21.Qxb8 Rxb8 before recapturing with d4.

47.a3 Rxb7 48.Rxb7 Kc6 49.Re7 Kd6 50.Rb7 Kc6 Here Nihal could have repeated moves and accepted a draw. The team would have won the match. Instead, Nihal decided to continue the game with 51.Rg7, declining the repetition as the position was winning for him. Unfortunately, he was extremely low on time, and then he claimed a draw with only two seconds left on the clock. The Chief Arbiter, IA Stephane Escafre, gave the decision as a draw, as his opponent Dardha had no objection.

Nihal Sarin and Daniel Dardha was an exciting battle which ended in a draw

The Captain of Alpine SG Pipers mentioned during their second game toss that there is a need to 'review' the decision. Perhaps a DRS or VAR needs to be introduced in chess too? It should also be noted that the Chief Arbiter of this event, IA Stephane Escafre (FRA), was also the Chief Arbiter of the World Championship Match 2018 between Magnus Carlsen and Fabiano Caruana. Also, the regulations do not mention anything about the draw claim rule.

Triveni Continental Kings - upGrad Mumba Masters: 3-0 (12-3)

Harika Dronavalli lost to Valentina Gunina. Alexandra Kosteniuk drew with Koneru Humpy. Alireza Firouzja won an endgame which could have gone either way against his compatriot Maxime Vachier-Lagrave. Wei Yi defeated Vidit Gujrathi to seal the match for the Triveni Continental Kings.

For the second time at this event, Alireza Firouzja had a double bishop vs double knight endgame. This time it was him who had a bishop pair against Maxime Vachier-Lagrave's two knights. Once again Firouzja was losing but he persevered and, eventually, MVL blundered and lost the game.

Master Class Vol.16 - Judit Polgar

In this video course, experts (Pelletier, Marin, Müller and Reeh) examine the games of Judit Polgar. Let them show you which openings Polgar chose to play, where her strength in middlegames were, or how she outplayed her opponents in the endgame.

Alireza Firouzja won the all-French battle against Maxime Vachier-Lagrave

Wei Yi made a nice practical bishop sacrifice to expose Vidit Gujrathi's kingside. 24...hxg6 25.Qh4 Kf7 26.Qh7+ Ke8 27.Qxg6+ Kd7 28.Rh6 and White eventually went on to win the game as it became incredibly difficult to defend.

Wei Yi is certainly going to be a force to be reckoned with for the rest of the tournament

Alpine SG Pipers - American Gambits: 3-0 (9-7)

The first result was a draw between Richard Rapport (ASGP) and Yangyi Yu (AG). Elisabeth Paehtz scored the first win for the team against Kateryna Lagno. R Praggnanandhaa drew with Jan-Krzysztof Duda. Magnus Carlsen and Hikaru Nakamura ended in a thrilling draw. Yifan Hou defeated Bibisara Assaubayeva.

Nakamura found an amazing defensive resource: 41.Rf4+ Kg7 42.g3 h4 43.Rxh4 fxg3+ 44.Kh1 Rg6 45.Rg1 Rexe6 as these were the only moves Black needed to find to save the game. 46.Rxg6+ Rxg6 47.Qb7+ Kf6 48.Qf7+ Kg5 49.Qxh7 Nf5 and here Black needed to play Rh6 to win the game.

Magnus Carlsen - Hikaru Nakamura was another battle for the ages
