Kibitzer's Corner
Jul-05-04  blitzkrieg: instead of repositioning his(black's)position, and knowing the fact that he is an exchange of knight ahead, he shouldn't had been greedy going after the a1 rook.after Rfd1, black is really in hot water.
Oct-28-04  Whitehat1963: Nice! I think this opening would work pretty well against my home computer program. Where does black make its worst mistake?
Oct-28-04  acirce: <Where does black make its worst mistake?> Probably taking the rook. After 12.Rd1 the game is over. 10..Nxc2 was bad but perhaps not yet completely hopeless.
Dec-24-04  MoonlitKnight: 5...Nxd5 is very bad and is a well-known beginner's mistake. The sacrifice of a pawn with either Na5, b5 or Nd4 is the only way to go. The latter two are the most aggressive (they often run into the same line), while Na5 is the most common. This game shows a textbook example of how to punish the ignorant.
May-09-05  Milo: 10...Qf6 comes to mind as a potential improvement.
Jan-15-06  blingice: Why do a lot of games between a great and NN degrade into the Fried Liver attack?
Jan-15-06  Dudley: Because most amateurs don't know that you can't safely take the pawn (5...Nxd5). 5...Na5 is the correct move in the Two Knights Defense.
Jan-15-06  Dudley: Also, the GM usually gets to play White in all the simul games which allows him to cheap shot the opponents at every opportunity!
Jan-16-08  Amarande: <Dudley> Actually, modern analysis appears to vindicate Black as far as 5 ... Nxd5 is concerned. However, it takes a strong player to conduct the defense properly, and is hardly something the typical simul Black can get away with.

The immediate 6 Nxf7 is actually second-best, as well (though normally quite sufficient for a GM against a simul opponent), and Black should equalize with a strong defense. No real improvements have been found for White in the main line Fried Liver.

White's best turns out to be the Lolli, 6 d4!, which was indeed for some time thought to bear out 5 ... Nxd5 as unsound. Even Tarrasch in his vitriol against 4 Ng5 could come up with no better than 6 ... Be6, which prevents a direct attack against the King, but this gives Black the inferior game nonetheless as White gets the two Bishops and the recapturing Black Pawn at e6 is weak.

Best after 6 d4! appears to be 6 ... Bb4+, which prevents White's Nc3 in the Fried Liver lines (either White blocks this square with 7 c3, or diverts the QN or Q after 7 Nd2 or 7 Bd2, or if 7 Kf1 to avoid these, Black can still counter a later Fried Liver attempt with Bxc3 when White attempts Nc3). The final word on this variation is still unclear, but it is apparent that this move (and thus 5 ... Nxd5) is indeed playable.

May-13-08  Whitehat1963: Excellent Monday/Tueday puzzle after 16...Ke8.
May-27-09  WhiteRook48: 17 e6!! the quiet move

  GrahamClayton: <acirce>10..♘xc2 was bad but perhaps not yet completely hopeless.

<acirce>,
US master Albert Pinkus recommended 10...♔e6 as Black's best option, eg

11.♘e4+ ♔c7 12.c3 ♘a6 13.♗a6 ba6 14.de5. White has two pawns for the piece and attacking possibilities, according to Jon Edwards' analysis.

Jun-16-14  RandomVisitor: 9.Bb3 is worth a look
Jun-22-20  sea7kenp: I set up the Position up to Black's 7th Move, and tried playing White against Stockfish. Not good! (Stockfish typically forces Simplification, to go into an Endgame a Piece up!)

Computers seem to like the Black side of the Fried Liver.

Jun-22-20  SChesshevsky: Znosko-Borovsky has a really good book called "Art of Chess Combination". Really more about successful attack than just combination.

Think it was Silman who said a few months studying the book helped add a couple hundred ratings points.

Jun-22-20  sea7kenp: I used some "Fuel" to get the insight of Stockfish. Its first major complaint was 10 ... Nxc2 (and also 11 ... Nxa1), with the suggestion of 10 ... Qf6 instead. Indeed, that's what Stockfish plays against me!
