Praggnanandhaa Rameshbabu secured his third consecutive victory to become the sole leader in the Tata Steel Masters after four rounds. Playing with white against Leon Luke Mendonca, Pragg displayed excellent strategic understanding in a Ruy Lopez. An early middlegame advantage led to an extra pawn, which he converted with precision into a 46-move win. With a score of 3½/4, the 19-year-old has gained 14.2 rating points, climbing five spots to number eight in the live ratings.
Nodirbek Abdusattorov, who shared the lead with Pragg after three rounds, missed a critical opportunity in his game against defending champion Wei Yi. Playing white, Abdusattorov could have gained a clear edge with 15.c5, as after 15...Bxd3 16.Qxd3 bxc5 17.Qb5+ Nc6 18.dxc5, White would have been in the driver’s seat.
However, he chose 15.Bf4 instead, allowing Wei to stabilise. The game eventually ended in a 43-move draw, leaving Abdusattorov half a point behind Pragg.
Attack like a Super Grandmaster
In this Fritztrainer: “Attack like a Super GM†with Gukesh we touch upon all aspects of his play, with special emphasis on how you can become a better attacking player.
Two other draws were Fabiano Caruana v. Anish Giri and Alexey Sarana v. Gukesh Dommaraju. Caruana and Gukesh, both in dangerous positions, managed to salvage half points. Gukesh was particularly tested, as Sarana pushed hard in their encounter. Both players now stand at +1, a full point behind the leader.

Pentala Harikrishna and Vladimir Fedoseev also scored victories in round four. Harikrishna played an impressive game against Max Warmerdam, sacrificing a knight on f7 early in the game to disrupt his opponent's king position. The attack culminated in a crushing victory in just 23 moves. Harikrishna later noted that his participation as a second in team Gukesh during the World Championship match against Ding Liren had significantly sharpened his play. (Find below expert analysis of the game by GM Daniel King).
Vladimir Fedoseev's victory came at the expense of an out-of-form Arjun Erigaisi, who continues his streak of poor performances in Wijk aan Zee. After winning the Challengers section in 2022 with an impressive 10½/13, Arjun struggled in the Masters the following year, scoring no wins and suffering five losses. His difficulties have carried into this year's edition, where he has started with three losses and a single draw, leaving him with a disappointing ½/4 score.
In his game against Fedoseev, Arjun had a clear advantage at one point but began to lose control after his 26th move. The critical mistake came on move 27 when he played 27.Nxf5 instead of the accurate 27.Re1.
This error by the Indian allowed Fedoseev to execute 27...Qxf5 28.Rxf5 Rxg3 29.hxg3 Ne3, forking Arjun's rooks.

How to Avoid Mistakes and Boost Your Winning Rate
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.
Round 4 results
Following a round in which all seven games ended decisively, favouring the players with the white pieces, Tuesday's fourth round of the Tata Steel Challengers section saw three games ending decisively. The three co-leaders - Thai Dai Van Nguyen, Erwin l'Ami and 14-year-old Lu Miaoyi - drew their respective games and remain tied at the top of the standings.
The decisive results came from Vaishali Rameshbabu, Divya Deshmukh and Benjamin Bok. Vaishali demonstrated strong tactical play to defeat Nodirbek Yakubboev with the black pieces. Divya overcame Ediz Gürel in a positional game that lasted 56 moves, while Bok outplayed Faustino Oro, the 11-year-old Argentine talent, who struggled to keep pace in their encounter.
