Rathanvel and Aryan in pursuit
134th seeded 11-year-old FM Ethan Vaz has made a phenomenal start. He defeated IM Ajay Karthikeyan, IM Ravi Teja S and 2521-rated Amirezza Pour Agha Bala (IRI). He will face GM Volodar Murzin in the fifth round.
Sankalp - Aryan: 0-1
The only other time GM Sankalp Gupta (2522) faced GM Aryan Chopra (2641) in a Classical rated game was back in 2019 at Asian Continental in China. That game ended in a draw. This one in Abu Dhabi was also heading towards a draw until Sankalp made a significant change in the position.
Changing structures in the endgame can have a huge impact. 41.c4? caused one. It shut White's bishop out completely. In the above position, it can be seen that the bishop has no safe squares to go to. 41...Be6 42.Rf1 Bg4 43.Rb1 Rf6 White cannot prevent Rf3+ 44.Kd2 Rf2+ 45.Kd3 Rf3+ and Black won the game soon.
Vantika - Yakubboev
53...Qg6?? is a blunder according to the computer as it allows White to advance his king. If Black wishes to trade the queens after 54.Qd8+ Qf6 it leads to a loss in the resultant pawn endgame which can transform into another queen endgame eventually. 55.Qxf6+ Kf6 56.f4 h4+ 57.Kxh4 exf4 58.Kg4 Ke5 59.Kf3 a5 60.a4 Kd4 61.Kxf4 Kxc4 62.Kf5 Kd3 63.e5 c4 64.exd6 c3 65.d7 c2 68.d8Q c1Q 69.Qb6 is a computer line, quite difficult for a human to calculate, especially if they are low on time.
Hari Madhavan - Kobalia
White cannot take the knight at e4 due to Bf5! However, there is nothing wrong with taking the other knight. So, IM Hari Madhavan N B (2418) went 21.Bxh5 Bf5 22.Ka1 exf4 23.Bxf4 Bg5 24.Bxg5 fxg5 25.Qh2 gxh5 26.Qxh5 Qg7 27.Nge2 Nf2 28.Rdg1 Bg6 29.Qxg5 Nxh1 30.Nf4 Nf2 31.Qh4 and White went on to win the game. This is a game that should be enjoyed because two humans played it, no computer preparation or anything is involved.
