Before you is the tournament book of the Tata Steel Chess Tournament 2021. The event that has been won in sensational fashion by the young Dutch grandmaster Jorden van Foreest. In a tiebreak in the third blitz game, he was just a bit faster of his compatriot Anish Giri. The barrage was necessary because both players very surprisingly ended with the wonderful score of 8½ out of 13 in joint first place. With this they had left behind, among others, World Champion Magnus Carlsen (7½) and the number two in the world, Fabiano Caruana (8). An unprecedented achievement, because the tournament in Wijk aan Zee is sometimes called the "Wimbledon of chess" of the elite tournaments. After the last round, in which Van Foreest in a formidable way had left the Swede Nils Grandelius chanceless, it was waiting for the game between the Spaniard David Antón Guijarra and Anish Giri. Our compatriot was in a bad position, lost perhaps, but he managed to free himself from the tangled position and gain an important half point. It was decided beforehand that a tiebreak would be held, consisting of at least two blitz games. Should these result in a 1-1 score, an Armageddon game would be played. This turned out to be a nervous and blood-curdling fight, with the pieces flying around. In the end the younger OF the two, Jorden van Foreest, emerged victorious and thus the young Groninger booked the greatest success of his still young career. Apart from the commotion in the Dutch seaside resort of Wijk aan Zee, where the tournament was held – under strict corona rules – the whole of the Netherlands rose to its feet when this great result became known. Hadn't we had to wait since 1985, when Jan Timman won the Hoogovens chess tournament, for a Dutch chess player to stand on the highest podium? And now it was even two players from this country who could dispute together who would take the highest honor That such a fine achievement should be immortalized, is beyond dispute. But who will pick up the gauntlet? We live in a volatile world where the Internet is dominant and when a tournament is over, the next one is already at the door. No time for reflection and historical awareness? Yet there was someone who had followed the tournament with great interest. The English grandmaster Daniel Fernandez, who also publishes for "ChessPublishing" came up with the idea of thoroughly examining all the games from this tournament. He did not take any chances in doing so. In addition to the various sources he found on the Internet, he of course used the strongest engines available at the moment. He also had engines in the cloud patiently calculate various positions. Together with his source research and his own insights, he has created a unique compilation of chess-technical material that is unprecedented. In doing so, Fernandez has painted a fantastic picture of the opening variants that were on the board in this tournament. He has done a thorough research of the ins and outs of the various variants and placed them in a broader perspective. And it must be said that the organization was kind to him by providing an interesting field of players who gave it their all every round. This resulted in many nice confrontations with extremely interesting opening theory! That Fernandez did not get away with the middle game and the many fascinating endgames was clear from a first estimate of the amount of material when it had to be converted to the format of this book. Initially, we ended up with almost 900 pages! That is far too much and therefore drastic cuts had to be made. Hundreds of (analysis) diagrams have been dropped, small side notes are no longer in the book and sometimes – pain in the heart – the trees of variations had to be cut back. That only happened, by the way, when the ingenious structure became so extensive that it would be hard to follow for "mere mortals". It is being considered whether this can be made available digitally at a later date, and the moment that it is, we will of course put Fernandez's entire analytical work on offer! IM Herman Grooten, December 2021 GM Daniel Fernandez (born 1995) is an English grandmaster with a slightly unusual approach to chess: at once mischievous and hardworking, and equally comfortable in tactical positions or dry endgames. His style fits the Modern perfectly and he has played it with success for almost a decade. He is a past holder of the British under-18 and under-21 titles, and the winner (or joint winner) of many open tournaments, such as Paracin 2017, Pula 2018, Ghent 2019 and the New Zealand Open 2020. Daniel also writes and commentates frequently, and is a columnist of the 1.e4 section on ChessPublishing.com. This is his third book for Thinkers Publishing, the Modernized Caro-Kann and Modern Defense were his first two and world wide acclaimed as the best you can get.
