Aronian nouveau leader à Grenke

Aronian nouveau leader à Grenke

Hou Yifan a raté la nulle et a perdu une finale instructive contre Maxime Vachier-Lagrave aujourd'hui au "Grenke Chess Classic". Le nouveau leader du tournoi est Levon Aronian, qui a battu Matthias Bluebaum.

Le score de Hou 2.5/3 était excellent, surtout si l'on prend en considération qu'elle a déjà joué contre les deux favoris du tournoi Carlsen et Caruana. Mais alors qu'elle n'a pas perdu de parties à Karlsruhe, son début à Baden Baden (le tournoi s'est comme prévu déplacé pour les quatre dernières rondes) n'a pas été bon. 

L'ouverture était une Berlinoise, et les joueurs sont finalement arrivés en finale (pas la fameuse finale de berlinoise). Dans cette partie les blancs ont eu l'avantage du début à la fin, avec une finale fou contre cavalier et une meilleure structure de pions

Maxime Vachier-Lagrave a eu l'impression de ne pas avoir été super précis, mais il faut aussi signaler que Hou Yifan a très bien défendu. Au 53ème coup MVL a tenté une nouvelle idée piégeuse et Hou n' pas réussi a trouvé la variante menant à la nulle que Dejan Bojkov va vous montrer dans l'analyse ci-dessous.

Levon Aronian took full advantage of the situation, as his win over Matthias Bluebaum leapfrogged him to sole first place. 

The Armenian's combo of the Chebanenko Slav (an early ...a6) and a Schlechter System (...c6, ...d5 and ...g6), which he claimed to have found at the board, was rather successful because Bluebaum played the opening too slowly. His 11.h3 was "careless" according to Aronian, while Bluebaum himself was even more critical. "Of course I could have played better after h3, but I was so disgusted about this move..."

Aronian ended up with an extra pawn in an endgame with heavy pieces. "There are always drawing chances, but if you're low on time..." (Aronian). This was the case for Bluebaum, who by the way celebrated his 20th birthday during the rest day.

"I tried to play Peter Svidler's style. Not to think, just to play fast," said Aronian, and it worked.

What about the two Cs? Well, Magnus Carlsen and Fabiano Caruana played a rather timid draw that started from an Exchange French, reached via a Petroff. Carlsen plays this every now and then vs the French, e.g. against Varuzhan Akobian during the PRO Chess League.

Caruana had considered it. "I had a very brief look at 8...Be6. Not more than five minutes." That turned out to be enough, as he calculated more accurately than Carlsen. The latter missed Caruana's reply to 15.Nb5?! and Carlsen went as far as calling this move a blunder. After that, the game quickly petered out to a draw.

The longest game was also the most dramatic. Arkadij Naiditsch outplayed Georg Meier from a London System, reached a winning endgame, even saw the winning line with 34.Ke1 but mixed up the moves and then let his opponent escape. A true Houdini act by Meier.
