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.
Fritz has fascinated the chess world for 30 years. And the success story continues. In Vienna, the most popular chess program ever was once again able to underline its premier position: the newly developed neural engine with NNUE technology won the official Chess Software World Championship!

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.

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.

Hou Yifan has been the sensation of the Grenke Chess Classic so far! 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.e4e52.Nf3Nc63.Bb5Nf6the well-known berlin defense!4.d3Bc55.c3d5!?5...0-0White can follow with 6.O-O or accept the sacrifice6.Bxc66.0-0d67.Nbd2 is a standard line6...bxc67.Nxe5d5may transpose to 5...d5 - See analysis on White's 6th move6.Nbd26.Nxe5accepting the sacrifice is dangerous0-07.Bxc67.Nxc6bxc68.Bxc6Bxf2+!9.Kxf2Ng4+10.Kg1Qf611.Qe2Qxc67...bxc68.d4seen recently at top levelBb6Black trusts his bishop pair and the development advantage9.0-09.Nxc6? would be too muchQe810.Ne5Ba6!9...dxe49...Nxe4was fine as well10.Nxc6Qd611.Nb4with decent compensation for Black with a5 followed by c5 or c5 right away: 1/2-1/2 (40) Morovic Fernandez,I (2550) -Faizrakhmanov,R (2432) Moscow 201710.Bg5c511.Nd2cxd4?according to Karjakin, he mixed up the lines during the game and ended up in a lost position - this was the main mistake probably11...Bb7!?11...h6!?12.Nxe4dxc313.Qf3!±1-0 (31) Wei,Y (2706)-Karjakin,S (2785) Wijk aan Zee 20176.exd5!?trying to maintain a more dynamic position, played in last October by SvidlerQxd57.Bc4Qd68.Qe20-09.Nbd2a510.Ng5Qe711.Nde4Bd612.a4h613.h4!looks very scary for Black.

In the other hand, the reduced material increases possible drawing chances.h520.Rac1c6It is good to find a solid square for your pieces in endgames - in this case Hou Yifan looks to place her knight on d5.

A very nice game from the Frenchman, who is still having a hard time in 6th place with 2/4. The new leader is Levon Aronian, the only player at 3/4!1–0
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.
