A long day, so a quick summary of the round 2 action at the Grenke Chess Classic: Magnus Carlsen ground down Michael Adams, helped a bit by the latter's time pressure. Oddly enough, this was the only win of the day; in fact, it is so far the only win of the entire tournament.
It's not that no one else has come close, though. Viswanathan Anand enjoyed a winning double-rook ending against Arkadij Naiditsch, but active play by Naiditsch and hesitant play from the former champ allowed the German #1 to escape.
The other German entrant, David Baramidze, had an easier time of things on the way to his draw with Levon Aronian. (Having the white pieces certainly didn't hurt.) Aronian was doing fine until he played 20...Be6; after that he was in some trouble until Baramidze played 25.b4. After that the players hoovered up everything and finished the game.
Finally, Fabiano Caruana was seriously better, off and on, against Etienne Bacrot, but it was never a comfortable and stable plus. The position remained complicated throughout, and at times Bacrot was even a little better. Such unbalanced and volatile positions are just very hard to play. The game marked a milestone of sorts: while it's only on the live list and isn't official, it is the first time in about half a year that someone other than Caruana was world #2, and the first time ever that Alexander Grischuk has held that spot.
