[October 05, 2018] Updated Opening Line by Slaviša Brenjo:
Ruy Lopez, Berlin Defense with 4. d3 Bc5 (incl. Kaufmann Variation)

[Line 372 : 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 Bc5 without 5. c3]

The main move 5. c3 is covered in Line 373, while among the alternatives 5. Bxc6 and 5. O-O seem most reliable.

After 5. Bxc6 dxc6 move 6. Qe2  has recently became popular. The idea is Nbd2-c4 and Bd2, followed by a pawn advance on the kingside, like e.g. in the game F. Caruana – S. Karjakin, Wijk aan Zee 2016. The more common continuation is 6. Nbd2, where both after 6… O-O 7. Nc4 Nd7 and 6… Be6 7. O-O Nd7, Black should equalize without difficulties.

In case of the 5. O-O, apart from a solid 5… d6, Black can exchange a pair of Knights with 5… Nd4, for example 6. Nxd4 Bxd4 7. Nd2 c6 8. Ba4 d6, and the ensuing position is roughly equal.

[Diagram: Black to Move] S. Movsesian – Z. Hracek, Sibenik 2009. Black has a better development and his opponent’s King is not placed very well. How can Black make use of these facts to seize a longterm initiative?
