It was a quiet round in terms of results, with six draws in seven games, but there was plenty of turbulence within the games themselves. Magnus Carlsen defeated Loek van Wely pretty easily (clearly better out of the opening, a pawn up 10 moves later, in a clearly winning rook ending about another 10 moves after that followed by a smooth conversion). That brought him back where he was before his loss to Richard Rapport in the previous round; namely, within half a point of the leader, Wesley So.
So had White in a Vienna Variation of the Queen's Gambit against Levon Aronian, and as the latter was well-prepared it was soon obvious that the game would finish in a draw. So remained in clear first with 6/9, while Aronian was a point behind.
Two players had an excellent chance to catch up with So. Pavel Eljanov was clearly winning against Dmitry Andreikin in a fantastically complicated game, but couldn't put him away and the game finished in a perpetual. Wei Yi's game with Baskaran Adhiban was quieter (to be fair, most of Tal's games would have been quieter than the Eljanov-Andreikin adventure), but in this game too the player nipping at So's heels should have won, but didn't.
Of the remaining draws, Ian Nepomniachtchi also failed to convert a winning advantage, though unlike Eljanov and Wei Yi he is nowhere near the top of the tournament table. His fortunate opponent, Penteala Harikrishna, isn't quite in the leading group, but is still close enough to make a run in the last four rounds. As for Anish Giri vs. Richard Rapport and Radoslaw Wojtaszek vs. Sergey Karjakin, those were correct draws.
My analysis of Carlsen-van Wely is here, and these are the pairings for round 10 (which won't be in Wijk aan Zee, in an implicit rebuke to my labeling this tournament in the traditional way rather than after its current sponsor, Tata Steel):
- Aronian (5) - Rapport (3.5)
- van Wely (1.5) - Giri (4.5)
- Harikrishna (4.5) - Carlsen (5.5)
- Adhiban (5) - Nepomniachtchi (3.5)
- Eljanov (5.5) - Wei Yi (5.5)
- Karjakin (5) - Andreikin (4)
- So (6) - Wojtaszek (4)
Things are tightening in the Challengers Group after the co-leaders scored .5/2 between them. Ragger only drew with White against Tari, while Jones was mated by Xiong. Smirin defeated Van Foreest with Black, so now he and Ragger share first with 6.5/9, half a point ahead of Xiong and Jones, a further half a point ahead of Hansen and Lu Shanglei.
