[August 21, 2017] Updated Opening Line by Bojan Vučković:
Ruy Lopez, Berlin Defense with 4. d3 Bc5 5.c3 (Main Line)

[Line 373 : 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 Bc5 5. c3]

Black’s most common choice in this line is 5… O-O, though 5… d5 has recently been tried by some very strong players, including Kramnik and Aronian.

White has tried many options in response to 5… O-O, and some of them are 6. Bxc6 bxc6 7. Nxe5 and 6. Bg5. Move 6. O-O probably deserves to be seen more often, where 6… Re8 and 6… d5 are decent alternatives to 6… d6. There are many possibilities for both sides almost on every move. Among them 6. O-O d6 7. Nbd2 is the most natural, where Black has a couple of options of about the same strength. Moves 7… a6, 7… Ne7 and 7… Bb6 are probably all good enough for equalizing without difficulties.

[Diagram: White to Move] White can obtain a lasting edge with 17. Nf6+ Nxf6 18. Qxf5, but there is an even better continuation for him, leading to an almost winning position. Any thoughts?
