In an interesting turn of events at the Lake Sevan Tournament 2015, GM Duda Jan Krzysztof overcame overnight joint-leader GM Vidit Gujrathi to join GM Anton Guijarro David at the top of the table after Round 4.
The Vidit – Duda game, which took off with the Semi-Slav defence, looked pleasant for Vidit in the early middlegame. However, Duda’s excellent move 25…g5 pretty much equalized the situation. With the trend against him, Vidit kept making small errors which eventually gave Duda a pleasant endgame. However, both the players struggled to find the best moves in the endgame, and on move 56, the Indian youngster had a chance to pull things back. Vidit not only missed the opportunity but also committed a flurry of mistakes which allowed Duda to decide the matters on move 64.
Amongst other results, GM Hovhannisyan toppled GM Petrosyan Tigran L while GM Artemiev, the top-seed, overcame GM Salem A. R. Saleh. Interestingly, all the wins in Round 4 were scored by players playing with the black pieces.
