Round five of the TePe Sigeman & Co tournament in Malmö produced two decisive results and left the event with two co-leaders. Arjun Erigaisi defeated Jorden van Foreest - who had defeated Magnus Carlsen the day before - to join Yagiz Kaan Erdogmus in first place on 3½/5. Carlsen also returned to winning ways, beating Zhu Jiner after his loss on Monday.
The two drawn games followed very different courses. Nils Grandelius, who had lost his first four games in Malmö, opted for a more restrained approach for the first time in the tournament and drew quickly against Nodirbek Abdusattorov. By contrast, Andy Woodward v. Erdogmus lasted 104 moves, with the US representative continuing to look for chances in a queen endgame with an extra pawn.
Grandmaster Dr. Karsten Müller, one of the world’s leading endgame experts, guides you step by step through everything you need to know in this second volume. Picture this: you’ve outplayed your opponent move by move, you’re clearly better – and then the endgame slips into a draw, simply because you lacked the crucial theoretical knowledge. That is exactly where this course comes in. Without solid endgame skills, there’s no way forward. Rook endgames are most essential: they occur more often than any other type of endgame, and often make the difference between victory and half a point. If you master them, you’ll confidently convert your advantages into wins!

Erdogmus' defence allowed him to remain undefeated and keep his share of first place with two rounds to go. The Turkish teenager and Erigaisi have already played each other, having drawn their round-two encounter, in which Erdogmus had the white pieces. Their remaining schedules now differ considerably: Erigaisi will face Zhu and Woodward, the two lowest-rated players in the field, as opposed to Erdogmus, who is due to meet Abdusattorov and Carlsen, the two highest-rated participants.

On paper, Erigaisi has the less demanding finish, but Erdogmus' recent rise and strong form in Malmö mean it should not be that surprising if he ends up winning the event. With the publication of the official FIDE rankings on 1 May, it was confirmed that Erdogmus is now the youngest player ever to have crossed the 2700 rating mark - the sky is the limit for the teenager from Bursa.
In this video course, Grandmaster Ivan Sokolov explores the fascinating world of Dutch and Grünfelkd structures with colours reversed. In this video course, Grandmaster Ivan Sokolov explores one of the most intriguing and under-examined areas of modern chess: reversed opening systems, focusing on the Reversed Grünfeld and the Reversed Dutch. At first glance, these two systems seem unrelated. However, they share a common strategic challenge: the value of tempi, structure, and psychology when familiar openings are played with colours reversed. Drawing on his long professional experience, Sokolov explains why these positions are far more subtle than they appear and why traditional engine evaluations often fail to capture their true complexity.

King’s Indian fans who choose the Mar del Plata attack (7...Nc6) against White’s classical system (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0) usually aim for a complex position with mutual attacks on open wings, requiring long-term strategic planning and tactical sharpness in critical moments. Computers often do not know how to handle the arising complex strategic positions, which suits players who like to think on their own instead of memorizing long variations. However, the fashionable Bayonet Attack (9.b4) interferes with Black’s ideas. After Black’s main move 9...Nh5 the positions opens, the lines get forced and computer analysis is important again. But this DVD offers an antidote against White’s Bayonet Attack, namely 9...a5! This move leads to sound positions with very few concrete lines, in which the focus is on strategy not on tactics. Objectively chances are equal but if Black knows what to do things might quickly become dangerous for White.

You will learn how Black's dynamic piece activity and structural counterplay more than compensate for White's extra tempo in the colour-reversed setups.
In this course, you’ll learn how to take the initiative against the London and prevent White from comfortably playing their usual system by playing 1.d4 Nf6 2.Bf4 Nh5.
