1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.f3!? This line is getting more and more popular.

8...Qa5 [8...f5 occured in Anand-Kramnik, in their match in Bonn (2008), game 2.]
9.e4 Nf6 10.Be3 0-0 11.Qb3 Nfd7 12.a4 Qc7 13.Qa3 b6 14.a5 Bb7N Nice novetly by Kramnik! [14...bxc5 was the usual move.]
15.a6 One of the best tries according to Deep Rybka 4.
15...Bc8 16.Bb5 Nxc5 17.Bxc5 bxc5 18.Ne2 Bd7 19.Bc4 From now on Kramnik started to think some five minutes per move. I think the text move shouldn't be the only one to equalize, though Black must pay some attention due to White's space advantage.
19...Bc6!? Giving the c-pawn for long-term compensations. This reminds, for instance, of some of the positions in the Bc4-Ne2 line in the Grunfeld. Black's safe development and pressure on the c-file is enough to compensate for an extra c-pawn. [19...Be8!? ]
20.Qxc5 Nd7 21.Qa5 Rfc8 22.Qxc7 I think after this move, White has no winning chances at all. [22.0-0!? should be a better try, though Black should be able to draw by force, somehow.]
22...Rxc7 23.Nd4 Bxe4 After this move, Kramnik started to play quickly until the draw was agreed.
