FIDE World Cup: Ding and Radjabov are in the semis

Time trouble

The FIDE World Cup is taking place in Khanty-Mansiysk. It is a seven-round knock-out event for 128 players, with a total prize fund of US$ 1.6 million and a first prize of US$ 110,000. The matches consist of two classical games with a time control of 90 minutes for 40 moves plus 30 minutes for the rest of the game, with an increment of 30 seconds per move. The finals consist of four classical games. Full schedule.

Time management was a crucial factor in the decisive games of the day. Teimour Radjabov played sharply against Jeffery Xiong's Grünfeld Defence, which led to both players needing to make their last moves before move 40 with only seconds on their clocks. Meanwhile, Alexander Grischuk was the one, unsurprisingly, having this problem in his game against Ding Liren — the Russian already had an inferior position but lost any remaining hopes while hurried by the clock.

This was the third time in the event that Radjabov advanced without needing tiebreaks, while Ding had only managed to do so once before, when he knocked out 1954-rated Shaun Press in the first round. The players will get a rest day before the all-important semi-finals. 

Given Ding's presence amongst the final four, it is worth noting that him getting the ticket to the Candidates via the World Cup would be good news for Anish Giri, who would become the favourite to get the spot given to the player with the highest rating average between February 2019 and January 2020. Ding is currently leading this race, while Maxime Vachier-Lagrave and Ian Nepomniachtchi are in third and fourth places, behind Giri — Martin Bennedik is running the numbers.

Ding Liren 1:0 Grischuk

The Chinese number one Ding Liren is one of three players in the world with a 2800+ rating. Despite his quiet demeanour, the 26-year-old has gained the respect of both the public and his colleagues. Already a couple of years ago, Carlsen chose him as rival for the Champions Showdown tournament in Saint Louis. Back then, the world champion got a whopping victory, but Ding has come a long way since — less than a month ago, the Chinese star won the Sinquefield Cup, after beating Carlsen in rapid play-offs.

Also, Ding often gets quiet positional victories against first-rate players. In his game with White versus Alexander Grischuk on Tuesday, he got a slight edge out of an English Opening, after the Russian chose a passive setup with his light-squared bishop on d7 instead of f5. Furthermore, Grischuk mishandled his clock and was in time trouble in the middlegame. Both contenders thought Black's critical mistake came on move 29:

Marin's English Love Vol.1 and 2 - A complete repertoire for White after 1.c4

The aim of these Dvd's is to build a repertoire after 1.c4 and 2.g3 for White. The first DVD includes the systems 1...e5, the Dutch and Indian setups. The second DVD includes the systems with 1...c5, 1...c6 and 1...e6.

Black played 29...♝e6, and Ding did not take long to execute the bishop trade with 30.♗xe6, as after 30...fxe6 31.♕e4 he managed to centralize his queen while keeping an eye on the c4 and e6 weaknesses.

White increased his advantage slowly but surely, combining small threats which led to the eventual capture of the c4-pawn. When the time control had passed, Grischuk realized it would have been hopeless to continue and resigned. The Russian still has good chances of getting into the Candidates via the Grand Prix, as he is currently in second place in the overall standings table.

Radjabov 1:0 Xiong

Jeffery Xiong played some of the most enterprising chess in Khanty-Mansiysk and his rematch game against Teimour Radjabov was not the exception. However, the youngster went for the Grünfeld Defence against a well-known theoretician, and soon found himself out of book. The Azeri grandmaster played a line not often seen amongst elite players, which prompted Xiong to start taking his time as early as move 8. Not long after, he made a critical mistake:

Fighting the Grünfeld with g3

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.

14...♜d8 seems natural enough, but precision was already essential at this point and 14...♝g5 was the correct way to go. The problem is that after the text White can go 15.f5 and the f-pawn will soon reach f6, leaving Black permanently threatened by a potential mate on g7.

The sharp position led to both players getting in time trouble, but Radjabov was clearly in the driver's seat all throughout. He had the sort of advantage that prompts the engines to give White a +2 advantage with equal material on the board:

Here 34.♕h6 was the most precise, but after 34.♖e7 Xiong did not play the best defence, 34...♜c2, and opted for 34...♜c1+ instead. Resignation came after 35.♔h2 ♜c3 36.♕h6.

The draws of the day

With Xiong eliminated, the biggest 'underdogs' still in contention are Yu Yangyi and Nikita Vitiugov — the 12th and 20th seeds respectively. After giving up an exchange and getting a draw with Black in game one, the Chinese handled the opening better than his opponent on Tuesday. He got the upper hand positionally but had his king still in the centre:

A lifetime repertoire: Play the Nimzo Indian

This DVD provides everything you need to know to be able to play one of the most classical openings with Black, the Nimzo-Indian, arising after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4. Nearly every World Championship and top tournament features the Nimzo-Indian.

Yu captured the a-pawn with 24.♖xa7, perhaps discarding the more poignant 24.♕xa7 due to 24...♝b3, with the threat of mate on d1. After the text, Black took control over the c-file with 24...♜c8 and went on to get a comfortable 40-move draw.

Vitiugov and Yu will decide their match-up on Wednesday's tiebreaks, much like Maxime Vachier-Lagrave and Levon Aronian, who needed about an hour to sign a 31-move draw out of an Italian Opening. Will we see another thrilling play-off between the French and the Armenian? Their 2017 match was one of the most exciting duels ever seen in a knock-out event.

Round-up show

Power Play 17 - Attack with 1.e4

A repertoire of attacking lines against the four major defences to 1.e4 – that is, 1...e5, the Sicilian, the French, and the Caro Kann. These systems will put your opponent under pressure, and when players are under pressure, mistakes occur. This is a practical repertoire – if we study openings we want to be sure to use them in our games.
