Untypical Miss

Vladimir Kramnik is famous for his great technique, but even the best can sometimes miss a chance. This is exactly what happened in his game against Liviu- Dieter Nisipeanu from round six of the Sparkassen Chess Meeting.

Magnus Grabs the Lead

Round five of the Gashimov Memorial was crucial for the leaders. Wesley So suffered his first loss to the former world champion Vishy Anand who showed his best chess so far in Azerbaijan. In the meanwhile the reigning champion Magnus Carlsen of Norway produced a real masterpiece to take the sole lead. His opponent in this game Maxime Vachier-Lagrave of France also appreciated the greatness of the game and did not look too disappointed at the end of it. Instead the two players spend a lot of time analyzing the game at a press-conference full of benevolence and positivness.
