The battle between the top two seeds in the Tata Steel Masters was a bit of a dud, as Wesley So and Magnus Carlsen finished in a short, peaceful draw, as did several other games in the round. And six of the seven games finished with shared honors (or dishonor, depending on the degree of one's antipathy towards draws), with the only decisive result occurring in the Pavel Eljanov vs. Richard Rapport game. Rapport played a slightly oddball opening line and had Black against a higher-rated, more experienced opponent, but it turns out that the opening wasn't to blame. Rapport was fine after the opening and even had a chance to be better. His 15th move was a critical error, and his inaccuracy on move 18 left him with a very unpleasant position. Eljanov soon obtained a dream position where Black had plenty of weaknesses and no counterplay, and confidently brought home the point.
Here are the round 2 pairings:
- Aronian (.5) - Wei Yi (.5)
- Nepomniachtchi (.5) - Andreikin (.5)
- Carlsen (.5) - Wojtaszek (.5)
- Giri (.5) - So (.5)
- Rapport (0) - Karjakin (.5)
- van Wely (.5) - Eljanov (1)
- Harikrishna (.5) - Adhiban (.5)
In the Challengers tournament the battle between #1 and #2 took a different turn. Markus Ragger obtained a serious advantage in the early middlegame, and although an error later gave Jeffery Xiong an opportunity to scrape out with a draw Ragger was the deserved victor when Xiong missed his chance. There were two other decisive games in this section: Jorden Van Foreest beat Erwin L'Ami, while Benjamin bok defeated Tingjie Lei.
I've annotated the Eljanov-Rapport and Ragger-Xiong games, which you can replay here.
