[February 08, 2019] Updated Opening Line by Trajko Nedev:
Petroff Defense, incl. Cochrane Gambit, Paulsen & Millennium Attacks and Kaufmann & Lasker Variations

[Line 352 : 1. e4 e5 2. Nf3 Nf6 3. Nxe5]

The only principal choice for Black on the third move is 3… d6, where as alternatives to the main 4. Nf3 White can also try the quiet Paulsen Variation (4. Nc4), and the sharp Cochrane Gambit (4. Nxf7), though it hardly gives him sufficient compensation for the sacrificed Knight.

After the most common 3… d6 4. Nf3 Nxe4 move 5. d4 is covered in our Lines 354-357, while 5. Nc3 is examined in Line 353.

The Lasker Variation 5. Qe2 leads to an early endgame after 5… Qe7 6. d3 Nf6 7. Bg5 Qxe2+ 8. Bxe2, where Black usually equalizes without difficulties.

Kaufmann Variation (5. c4) is aimed against d6-d5. Black generally has no problems obtaining a comfortable position here, for example 5… Nc6 6. d4 d5 7. c5 Bg4, and Black is fine.

Also, in the Millennium Attack (5. Bd3) Black has good prospects, for instance 5… Nf6 6. O-O Be7 7. h3 O-O 8. c3 b6 9. Bc2 Bb7 10. d4 Nbd7, with equality.
