Fried Liver analysis on rybkaforum.net?

I tried to browse it using web.archive.org website, but I don't remember when (which year) and where (which place in the forum) it was posted...

There was some collective analysis of Fried Liver, after some poster postulated that black is okay in this variation.

Thank you in advance and Happy New Year of 2024! :)

Hmmm... should be a thematic tournament some time ;) Happy new year Ilmars!

Does someone want to test this variation (to play it with white and try to win):

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5 6. Nxf7 Kxf7 7. Qf3+ Ke6 8. Nc3 Ncb4 9. O-O c6 10. d4 Qf6 11. Qd1 Ke7 12. Re1 h6 13. Rxe5+ Kd8 14. Ne4 Qg6 15. a3 Bf5 16. Ng3 Bxc2 17. Qf3 Nd3 18. Rf5 Bd6 19. Bxd3 Bxd3 20. Qxd3 Kc7 21. Bd2 Rhf8

I'm currently analysing it.

The 21... Rae8 seems to be losing (I lost the game against Scott Nichols convincingly).

21... Rhf8 against Scott ended in draw.

Then we explored 13.Ne4 a bit:

I checked the Fried Liver with Stockfish 16, just far enough to convince myself that black can probably hold the draw. I'll post five key lines along with the eval at the end of each line, including the FEN encoding of the position being evaluated. I went through white's options and I see no way for white to improve on these lines, although 6 d4 instead of Nxf7 should also be checked. Anyway here are the line evaluations.

The Lolli (6 d4) is no better for white. Black survives in the following line, and white has no other options worth checking.

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5 6. d4 Nxd4 7. c3 b5 8. Bd3 h6 9. Nxf7 Kxf7 10. cxd4 exd4 11. O-O Rb8

Interesting! Thank you!

At what depth are these evals made?


Scott Ligon    (2024-01-12 22:51:02)
Fried Liver analysis on rybkaforum.net?

For the 6 lines I posted, those eval depths are, in order:
46, 47, 45, 46, 45, 43.

For the line with the highest eval of +0.80, the win percentage for white is given as 27.4%, so further analysis might be warranted but that's where I left it. My understanding is that Stockfish 16 changed the semantics of the numeric evaluations. An eval of +1.0 used to mean white had a one pawn advantage (in some very abstract sense), but now +1.0 is supposed to correlate with a 50% probability that white has an objectively winning position.


Ilmars Cirulis    (2024-01-13 09:16:39)
Fried Liver analysis on rybkaforum.net?

After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3 Nb4 9.O-O c6 10.d4 Qf6 11.Qd1 Ke7 12.Re1 h6 there is also 13.Bb3 with +0.64 for white (at depth 52). Something more to explore. :)


Scott Ligon    (2024-01-13 20:47:35)
Fried Liver analysis on rybkaforum.net?

In that case, I don't think white can improve on the following line (depth 49):

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5 6. Nxf7 Kxf7 7. Qf3+ Ke6 8. Nc3 Nb4 9. O-O c6 10. d4 Qf6 11. Qd1 Ke7 12. Re1 h6 13. Bb3 Bf5 14. Bd2 a5 15. Nxd5+ Nxd5 16. c4 Nb4 17. Rxe5+ Kd8 18. a3 Nd3 19. Bxa5+ Rxa5 20. Rxa5 Kc7

I put all the variations after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3 Nb4 9.O-O c6 10.d4 Qf6 11.Qd1 here: https://lichess.org/study/MYMU6aQ7

Will add 11.Qe2 variation(s) too a bit later.

The Fried Liver just seems like a bad choice for black when the main line (5... Na5) equalizes, and if you want something different there's 5... b5 where white gets some advantage with 6. Bf1 but more frequently plays 6. Bxb5 where black is again equal and can expect to be more familiar with the position. I had a look at your lichess study. Are you mainly just taking notes on the computer evaluations of various lines as a general reference, or is this something you actually intend to learn in detail so you can play it?


Ilmars Cirulis    (2024-01-17 13:47:31)
Fried Liver analysis on rybkaforum.net?

Lichess study is for reference, yes. Also it's nice to have everything in one place, where it can be browsed through (and can be downloaded as PGN file, if necessary).

Yes, I agree that Fried Liver is bad choice for black. Not going to learn it for OTB, definitely.

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5 6. Nxf7 Kxf7 7. Qf3+ Ke6 8. Nc3 Nb4 9. O-O c6 10. d4 Qf6 11. Qd1 Ke7 12. Re1 h6 13. Rxe5+ Kd8 14. Ne4 Qg6 15. a3 Bf5 16. Ng3 Bxc2 17. Qf3 Nd3 18. Rf5 Bd6 19. Bxd3 Bxd3 20. Qxd3 Kc7 21. Bd2 Rhf8 22. Rd1 b6 - still don't know for sure if this is a draw or maybe white can win somehow...

When is thematic tournament(s) happening? :sweat_smile:


Ilmars Cirulis    (2024-02-18 18:06:06)
Fried Liver analysis on rybkaforum.net?

12.--- Qg6 is losing, I believe (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3 Nb4 9.O-O c6 10.d4 Qf6 11.Qd1 Ke7 12.Re1), therefore such focus on 12... h6 variation.

Played thematic game with Bahadir Ozen at LSS, added it to Lichess study:

https://lichess.org/study/MYMU6aQ7/dA04utCi

It ended in interesting, imho, draw. :)
