Erdogmus, Zhu and Van Foreest score
Round four of the TePe Sigeman & Co Chess Tournament brought three decisive games and a significant shift in the standings. Yagiz Kaan Erdogmus, the 14-year-old Turkish prodigy, moved into sole first place after beating Nils Grandelius, while Jorden van Foreest scored his first-ever win over Magnus Carlsen. Zhu Jiner, meanwhile, collected her first victory of the event, defeating Andy Woodward. The only draw of the day came in the game between Nodirbek Abdusattorov and Arjun Erigaisi.
Round 4 results
Erdogmus is now the outright leader on a plus-two score. The rising star has beaten Zhu and Grandelius, while drawing his other two games, giving him a half-point lead with three rounds to play in the seven-round event. His latest win also deepened Grandelius' difficult start in Malmö: the Swedish number one has now lost all four of his games in the tournament.

Three players stand half a point behind the leader. Abdusattorov and Erigaisi remain in close contention after splitting the point in the only drawn game of the round, although the battle could have developed in Abdusattorov's favour, who had also left an advantage slip in his Saturday encounter against Woodward.
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.

Van Foreest joined Abdusattorov and Erigaisi in the chasing group after the most notable result of the day. Playing with the white pieces, the Dutch GM defeated Carlsen in an exciting, 88-move game, earning his first victory over the multiple world champion.
After gaining an extra pawn in a queenless position, Van Foreest had to work hard to beat his famed opponent, as the Norwegian was inches away from escaping in the technical endgame that arose with rook and pawn against knight and two pawns.
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!

Zhu's win over Woodward was also important for the standings. After a difficult start, the Chinese grandmaster got off the mark by handing Woodward his first loss of the tournament. Woodward, who had begun the event with a win over Grandelius and then remained among the leaders, is now tied for fifth place with Carlsen. Both players have one win, two draws and one loss after four rounds.

‘New ideas in the Najdorf – a Power Play 18 Update’ aims to complement Daniel King’s popular DVD from last year ‘The Sicilian Najdorf - a repertoire for Black’. Such a dynamic and popular opening as the Najdorf is developing the whole time. On this download, Daniel King updates lines that were included on his DVD but also responds to viewers’ requests, considering lines that he omitted from his original repertoire. The lines examined on this update are:
• 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 h3 e5 7 Nde2
• 5….a6 6 Bc4 in combination with the English Attack (Be3, f3 etc)
• 5…a6 6 Be3 and the …a5 variation
• 5…a6 6 Be2 and 9 Re1
• 5 f3 (instead of 5 Nc3)
It isn’t necessary to have seen the original Najdorf DVD to understand the lines examined here – but it would help as they form part of a complete repertoire.
