The Damiano Petroff

There is a new Chessable course about the Damiano Petroff...that’s 1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4?! so we’re having a tournament about it with some real prizes: lichess.org/tournament/RKz3CXyy

Classic consensus is that, with very accurate play, the best Black can hope for is a lost pawn. As MCO-15 annotates it on page 101: 1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4? 4. Qe2 Qe7 5. Qxe4 d6 6. d4 and Black has lost a pawn.

Recently, there has come out a Chessable course which points out that:

- Black is OK in this line of the Petroff, as long as they play accurately
- There are a lot of lines which are difficult for White to refute over the board

One user on Reddit had access to a 72 core server and analyzed things with Stockfish 15 70 ply deep starting on move 4. Here is the main line Stockfish saw:

I think it’s nice we’re going to a lot of effort to look over this line again. I always considered 3... Nxe4?! a mistake myself, and still remember beating a friend in a casual skittles game who then defended poorly after making the Damiano Petroff move: 1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4?! 4. Qe2 f6?? 5. Qh5+ g6 6. Nxg6 hxg6 7. Qxg6+ and Black didn’t last very long. After showing that game to my informal chess coach, his line was this: “After 3. Nxe4?! he made one mistake. He couldn’t afford another mistake.”
It‘s not easy. We call the regular Petroff „Russian“ and this particular line „Super-Russian“.
Supposedly, it’s playable for Black after 1. e4 e5 2. Nf3 Nf6 3. Nxe5 Nxe4?! 4. Qe2 Qe7 5. Qxe4 d6 6. d4 dxe5 7. dxe5 Nc6 8. Nc3 Qxe5 9. Qxe5+ Nxe5 10. Bf4 Bd6 11. Bg3 h5

Here’s Stockfish 72-core 70 ply analysis of that position:



The trick is to avoid greed with 8. Nc3
Well, the tournament for this line is done. The final results were 4,712 White wins, 3,963 Black wins, and 653 draws. That’s 51/42/7 (White win/lose/draw percentages), compared to 48/45/7 for all games played on Lichess, so even at club level, playing 3. Nxe4?! gives White an edge.
Since someone asked me this in a private message: MCO-15 is Modern Chess Openings, 15th edition.
