Время публикации: 02.05.2012 21:11 | Последнее обновление: 15.12.2012 19:37

In the 5th round of Nakhchivan Open the leader Viorel Iordachescu beat Aleksej Aleksandrov, who inaccurately played one of the important sidelines of his favourite Berlin system in the Ruy Lopez. Black's position has become worse already at move 20, later Moldovan player managed to convert his advantage.

At the moment Iordachescu has 4.5 points out of 5.

Sergei Zhigalko, who outplayed Vugar Rasulov in a protracted game where Chinese dragon line took place, and Sergei Tiviakov, who managed to defeat Baris Esen, are half a point behind the leader. In the second encounter the Dragon variation was only flickering.  

TIVIAKOV - ESEN

Avoiding 5...cxd4 6.Nxd4, which would lead Black to less dangerous line of Dragon - the variation in which Tiviakov is recognized as an expert, Esen preferred 5...Na6 - the unknown move for the database. Soon the game went to Ufimtsev defence, which has been played by Kramnik in blitz.  

The Turkish player's stubborn unwillingness of exchanging on d4 caused Tiviakov's breakthrough in the center by e4-e5 on 11th move, which allowed him to grab the initiative. Black failed to hold the worse position.
