4/20/2017 – Without a doubt, round four brought in a number of dramatic moments for those watching the games live. The one ‘letdown’, if one may, was the uneventful draw between Carlsen and Caruana on top board. Naiditsch and Meier had a crazy game that drew in the end, while Aronian defeated Bluebaum very cleanly to take the lead after Hou Yifan lost to MVL in a tough endgame that is annotated in detail by GM Krikor Mekhitarian.

Video highlights of round four
The big draw of the day, in theory, was Magnus Carlsen against Fabiano Caruana. Both have been embroiled in some might battles in the past, but today was not one of them. It started as a Petroff, which sort of told the story, then via a strange move order transposed into a French Exchange when Carlsen played 5.d3 and then 6.d4. The queens were off by move 14, and though they danced a little, with threats of seeing something happen, they drew.
Magnus Carlsen and Fabiano Caruana failed to thrill in round four

The gleam of excitement in the commentator's eyes
The next big bout was between MVL and Hou Yifan and this one was a thriller
The next game, if not the first, to not let anyone look away was the battle between world no. 5 Maxime Vachier-Lagrave and Hou Yifan. Hou Yifan’s success until now was absolute, and the Frenchman had shown uneven form. However, Maxime is known for being a particularly good player with white, and this showed in round four. He obtained a significant advantage in an endgame, which could theoretically be held. The fight was long and strenuous and Hou Yifan was the first to blink but the game was fascinating, and comes here with detailed analysis by GM Krikor Mekhitarian.

She was the sole leader after the 3rd round, having beaten world number 3 Fabiano Caruana and GM Georg Meier, and achieved a draw after building a great advantage against the world champion Magnus Carlsen. Today she had a tough task, to hold her ground against the world number 5, Maxime Vachier-Lagrave, known for his strong play with the white pieces.} 1. e4 e5 2. Nf3 Nc6 3.

Maxime Vachier-Lagrave was the dragon slayer today as he defeated tournament leader Hou Yifan. Here he gives a few post-mortem comments.
Arkadij Naiditsch had a chance to join the lead, but by the time he realized he had a first calss ticket in his hand, the train had left the station
Arkadij Naidistch and Georg Meier played a strange game that held significant advantages for both sides at different moments. Naidistch emerged on top after a series of complications, but failed to divine the killer blow, and after missing his chances twice in a row, the moment passed and equality was held until the end.

The final game, and decisive, was the strong win by Levon Aronian over Matthias Blluebaum. Although Aronian was the obvious favorite from the onset, it didn’t help that Bluebaum tried to play risk free, and failed to make any chances. The end result was that the Armenian won a nice endgame and thanks to MVL’s help, by defeating Hou Yifan, is now the sole leader with 3.0/4 and three rounds to go.
