At Carl sens 31st birthday, the world champion decided — unlike his first game with the white stones — for an opening with the Romanians, Nepomnjaschi played the Petrov defense.
Nero defends solid
Both players were well-prepared and moved quickly, the grand master exchanged their runners, ladies, and a few jumpers. After some well-known trains, Carlson, who made for the first surprise: with 18. SH4 instead of the usual 18th BXA6 made the birthday child the game a bit more dynamic: Himself Carlson gave an active jumper and a free-farmers on the D- Line, made possible its counterparty but its own defended fraudsters on the A-line. Nepomnjaschi did not liberate himself from this, the challenger played solid and held the game balanced.
In the episode, Carlson brought a tower on the seventh place and thought about the position over 40 minutes, but did not seem to find weaknesses in the defense of the Russian. Finally, the defending champion decided to have seized the initiative to repeat the position. A surprise as the Norwegian is actually known to play out balanced positions for hours to find and exploit small inaccuracies of his opponent. Nepomnjaschi was thankful for the passive retirement offer, so that the fourth party of the duel ended undecided.
A normal result against a well-prepared opponent.
Magnus Carlson
I just did not want to make a mistake. I knew that this variant is quite sure for me. I am pleased with the draw, the challenger appreciated the game. Carlson delivered a sober analysis: It’s a normal result against a well-prepared opponent.
Tomorrow, Wednesday, the fifth match (13.30 clock) takes place before a renewed rest day is filed on Thursday.
