Finek and Divya score wins
After five rounds of the Challengers tournament at the Prague Chess Festival, 16-year-old Vaclav Finek stands clear at the top of the table with a full-point lead. The Czech IM secured his third victory of the event on Sunday by defeating Daniil Yuffa with the white pieces, moving to 4/5. His remaining two games have both ended in draws.
Yuffa had been one of four players trailing Finek by half a point before the round began. The loss leaves him outside the chasing group, which now includes Thomas Beerdsen, Jachym Nemec and Stepan Hrbek, all of whom drew their games in the final round before the rest day and trail the leader by a full point on 3/5.
The key game between Finek and Yuffa turned on a strategic decision. Yuffa chose to exchange his dark-squared bishop, a trade that left the dark-square complex around his king significantly weakened.
Finek responded energetically, advancing his kingside pawns and maintaining pressure in a position where all six major pieces remained on the board.
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.

With his opponent's king exposed, Finek gradually increased the tension and converted his advantage in convincing fashion.
The only other decisive result of the day was scored by Divya Deshmukh, who obtained her first win of the tournament by defeating Surya Shekhar Ganguly with the black pieces. Deshmukh thus returned to a fifty-percent score, recovering from her earlier setback against Zhu Jiner in round three.
The critical moment came when Ganguly opted for 19.Nxh7?, a knight sacrifice that did not yield sufficient compensation.
White could have gone for 19.Qh3 and, in fact, have a slight advantage. Instead, there followed 19.Nxh7? Qh5 (the refutation) 20.Nxf6+ gxf6 21.f3 Qxh2+ 22.Kf2 Qh4+ 23.Kf1
Doesn’t every chess game get decided by mistakes? Absolutely. But most players never truly comprehend that they are making the same kind of mistakes over and over again.
The black knight jumped from e7 to d5 and from d5 to c3 in the following two moves, forking the rooks to gain an exchange. Ganguly resigned the game on move 35.

Among the three drawn games, the encounter between Zhu and top seed Benjamin Gledura stood out. Zhu agreed to a draw by triple repetition in a position that engines assessed as better for her, with an evaluation of around +1.3.
In this course, we will learn how to identify passively placed pieces in any given situation and how to improve their health by bringing them into active squares.
Given her difficult start to the tournament, which had seen her lose three of her first four games, the practical decision to secure half a point was understandable.
