There wasn't much excitement in Wesley So's game. Sergey Karjakin played a slow system with White against the leader, and by move 22 they were already content to shake hands and call it a day. That meant that Wei Yi, Pavel Eljanov, and of course world champion Magnus Carlsen could catch So with a win.
Wei Yi's game with Pentala Harikrishna was a short draw with Black in a Petroff, so nothing doing there. Eljanov, however, was winning against Radoslaw Wojtaszek, and at two different points in the game. Unfortunately for the early leader of the tournament, he failed to convert his advantage, and also drew. Still, that's better than what happened to Carlsen. Carlsen more or less equalized against Richard Rapport, but chose a very bad play with 22...d3 23.e3 Ne5. Perhaps this was due to a surfeit of ambition; whatever the case, he was losing two moves later, and Rapport finished with a nice little combination starting with 29.Rb6. It had been a bad tournament for Rapport and a good one for Carlsen, but even so Rapport is too strong a player for even Carlsen to take such liberties against.
In other games: Levon Aronian demonstrated an interesting new idea in the Catalan and won a terrific game against Anish Giri, and Baskaran Adhiban also won in crushing style against Dmitry Andreikin. Finally, in a battle between players at and near the bottom of the crosstable, Loek van Wely failed to convert a winning advantage against Ian Nepomniachtchi, and they eventually drew the longest game of the round.
The decisive games, with my comments, are here, and here are the pairings for round 9 (on Tuesday):
- So (5.5) - Aronian (4.5)
- Wojtaszek (3.5) - Karjakin (4.5)
- Andreikin (3.5) - Eljanov (5)
- Wei Yi (5) - Adhiban (4.5)
- Nepomniachtchi (3) - Harikrishna (4)
- Carlsen (4.5) - van Wely (1.5)
- Giri (4) - Rapport (3)
In the Challengers section, six of the seven games were drawn, which is very unusual - all the prior rounds had at least three decisive games (and that low number only occurred once, in round 1) and one round even saw seven decisive games out of seven. The only non-draw featured players near the bottom of the table, so the relative standings are the same: Jones and Ragger lead, half a point ahead of Smirin and a full point in front of Lu Shanglei and Xiong.
