Humans Too

The last tournament from the Grand Prix series is in progress in Khanty-Mansiysk, Russia.
A game that I liked (ChessBase 13) Fabiano Caruana is leading before the free day with 3/4, but it could have been different if Evgeny Tomashevsky had won his game in round two. This game proved that the top GM are also human beings, tending to make mistakes.

"Retired Old Man"

"The Battle of the Legends" took part in St. Louis at the end of April. Garry Kaparov and Nigel Short met again 22 years after their WWC match. The match consisted of ten games- two rapid and eight blitz. The first day was good for Kasparov who proved that he is still capable of producing great games. He won 3.5-1.5 that day but was not satisfied with the result as he missed a clear win in the first rapid game and lost on time in one of the blitz games. It seems as he wanted to prove who is the boss in the second day and it started with the following encounter:

Stubborn Defense

Fabiano Caruana significantly improved his tournament situation in Shamkir after an important win with the Black pieces against the former world champion Vladimir Kramnik.The Italian GM had to survive at first the strong pressure that his opponent put on him. The moment in which Kramnik decided to open up the game was not chosen right and the tables have turned into Caruana's favour.

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.

An Excellent Technique

Just like Magnus Carlsen in the second round Wesley So demonstrated great technique against Rauf Mamedov. Round four saw the Philippine-born American Grandmaster take the lead in Shamkir with remarkable start- 3.5/4!
A game that I liked (ChessBase 13)
