Indonesia Chess Open 2013 Round 4: GM Ivan Ivanisevic Leads

Chess Blog for Daily Chess News and Trivia (c) Alexandra Kosteniuk, 2013

Hello everyone,

It has taken four rounds of play to have a sole leader at the Indonesia Chess Open 2013. GM Ivan Ivanisevic, who was leading with GM Avetik Grigoryan until the previous round, has taken sole lead after four rounds with a perfect score. On 3.5/4 are GMs Aleksey Dreev, Surya Shekhar Ganguly and Hoang Thanh Trang. Dreev outplayed local hope GM Susanto Megaranto in the endgame after achieving a better pawn structure while Ganguly was simply too strong for GM John Paul Gomez. But the main attention was on the Hoang encounter with GM Oliver Barbosa, where the Filipino sacrificed his Queen for a number of active minor pieces and a dangerous looking attack along open files against an exposed King. Hoang, however, played with great accuracy, combining attack and defense with her Queen and brought home the point.

You can replay the Hoang Thanh Trang - Oliver Barbosa game with Chess King.
In other significant GM encounters, top seeded Alexander Moiseeko managed to win the exchange, but Sandro Marco generated resources to draw, while the former student Eshan Ghaem Maghami held the draw against his old teacher Nigel Short. Vaibhav Suri was happy to use the white pieces to also draw the higher rated Eduardo Iturrizaga, while it was the same result in the match-ups between Igarza Renier Vazquez and Gundavaa Bayarsaikhan, and Jan Ehvest and Antoaneta Stefanova.

Vadmim Malakhattko came close to winning against Abhijeet Gupta, but the Indian GM was able to liquidate into a drawn Rook ending.

With Megaranto losing, the best Indonesian player is again Anjas Novitas who recovered from his first loss against a GM in the third round to beat WGM Elisabeth Paehtz.
