Perhaps still smarting from yesterday's defeat, Levon Aronian didn't undertake too much against Vladimir Kramnik's Berlin Defense and the game was drawn fairly quickly and comfortably by Black. That leaves the match tied 2-2, and after the rest day tomorrow they'll finish with games on Friday and Saturday.
The players decided before the match that in case of a draw lasting fewer than three hours they'd play a rapid game with colors reversed, and so they did. The game was for purely exhibition purposes, having no relevance to the match score or prize fund or anything else, so they could have some fun - and they did. Kramnik played 1.e4 and went on a bit of an attacking spree; unfortunately for him and the spectacle, he failed to follow up with the right move at the critical point. (The move in question is 25.Ne5, which he saw, as they immediately started analyzing it after the game, but rejected for some reason.) Aronian went on to win the entertaining game with a nice finish.
Here are both games, with my comments.
