While India is abuzz with Sachin's last test, the game 4 of Anand - Carlsen was wonderful. The 16th move of Carlsen (Bxa2) was a risky line but he had obviously prepared for it. It turned a boring Berlin opening to one of the best games.
There was an alternative to 28. hxg4, which was Rc1. But it was impossible to spot (though my computer engine picked it up). I think the advantage was with Carlsen throughout the match but Anand played 35. Ne4, which neutralized the advantage. Overall, it was a very quality match and a pleasure to watch and analyze so many lines.
