Thanks, Micawber! 

I have done a fair bit of research and didn't come up with anything prior to 1996 either. The person who originally told me that Larry Evans published analysis now says it was one of Ken Smith's Chess Digest pamphlets, but he doesn't have it anymore. I'll keep looking, but I think this may be a wild goose chase.

Does anyone have the Chess Digest Pamphlet on the Traxler or perhaps the Two Knights that covers this line?


Here are three sources pre-1996:

Gregor Cramer, Traxler-Gegenangriff Fritz Variante Ulvestad Variante, Breyer Verlag, 1993

Yakov Estrin's "Wilkes-Barre Variation," Chess Enterprises, Inc. 1978.

Ken Williams, "The Real American Wilkes Barre," Chess Enterprises, Inc. 1978

See also John Donaldson, "Death Knell for the Wilkes Barre?" Inside Chess, v. 4, Issue 13, p.19.

Ah, thanks for the link.
5.Nxf7 is a great move for analysts, but OTB one would always pick 5.Bxf7+ Ke7 6.Bd5 or Bb3 and be more or less a pawn up for nothing- or even play 5.d4, which also is very annoying to meet.

11.Be2,0-0 12.Kg2,Rxf7 13.Rf1,Rxf1 14.Qxf1,Be6 unclear
was given by Martin Bennedik who was an expert on this line around 1999.
11....Qe4+ 12.Kf2, 0-0 seems to be sufficient for equality as well. I am not aware of any games prior to 1996.

For those looking for some background around this line or on the schmidt attack:

Thanks PANFR, I too found several minor correspondence games with Be2, but I haven't found any reference to games played by Marshall or any theoretical articles that mention it. 

Does anyone else know the pedigree of 11.Be2, or is it just a random move?

Some years ago , I proposed
5 Bxf7+ Ke7 6 b4!? ( Schmidt attack ) , and I played it myself in a corr. game
I can no more find my analyzes but I remember the position is very rich and as complex as , for instance , the Cambridge Gambit in the Alekhine
It desrves a further examination with "modern" engines

There are seven games with 11.Be2 in the online chesslive.de database.
I see no reason trying that as white- black seems comfortably equal after 11...0-0 and 11...Qe4, and 11...Rf8!? is also interesting, with the idea 12.Kg2 Rxf7 13.Rf1 Bf5 14.d3 0-0-0 (I will admit I don't particularly like this idea).

Hi, 

I'm trying to find out the pedigree of the following line: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Nf7 Bf2 6.Kf2 Ne4 7.Ke3?!/!? Qh4 (Nunn considers 7....Qe7 to give Black an edge, but Estrin thought White has an edge after 8.c3! I don't know which was correct) 8.g3 Ng3 9.hg3 Qd4 10.Kf3 d5 11.Be2 instead of 11.Rh4, which is the only move in my database and the only move in chessgames.com's database also.

Someone told me that there was a game that Marshall played with 11.Be2, and that Larry Evans mentioned it also. However, I haven't found any such games or references.  When has this been played, and is there any theory on this position beyond 11.Rh4 with a probable draw in the next few moves?

There 's an  answer elsewhere in the Forum and the concensus is black is OK


Of course black is okay, but this analysis may contain some improvements. If anyone has please send me.

Then perhaps you could comment on this. That would be more fruitfull than just repeating your question on page 1, don't you think?

de Zeeuw Refutation number 5:
5.Bxf7 Ke7 6.Bb3 and now Qe8, which scores the best in the computer for Black, is not looked at, other than to say that it might transpose back into the main line. 5...Kf8 is actually playable, but not analyzed.
 
Note - this line is probably White's best response to the Traxler.

[+0.68]  d=27  6.Bb3 d6 7.d3 Qe8 8.c3 Rf8 9.Nf3 h6 10.Nbd2 (425:13.49) 54251499kN

Not all is lost with 5.Bxf7+ Ke7 6.Bb3.

I have analysed four possible moves that have any real significance.

A: 6...Qf8?

This was one of my attempts to rehabilitate the main line.  It is dubious though and more of a surprise than a good move.

7.0-0! (7.d3 Bxf2+) 7…d6 8.Nc3 Bg4 9.Nd5+ Kd8 10.Nxf6 Bxd1 11.Ne6+ Kc8 12.Nxf6 gxf6 13.Rxd1 Rxf8 14.c3 and black is struggling for a draw in the endgame.

B: 6...Rf8?

I am going to be bold and call this move an outright error.  White has quite a few lines where they can hold the advantage and in some cases leave black in shambles.  This is the old main line and should be discarded.


B1: 7.0-0 d6 (7…h6 8.Nf3 d6 9.d3 Bg4 10.Be3 Nh5 11.Nbd2 and white has a significant advantage) and two more sub variations arise.

 

B1A: 8.d3 Bg4 9.Nf3 (9.Qe1 h6 10.h3 hxg5 11.hxg4 Qe8 12.Bxg5 [12.Qd1 Qg6] 12…Qg6 13.Be3 [13.Qd2 Rh8] 13…Nxg4 14.Bxc5 Qh5 and black is winning) 9…Nd4 10.Nbd2 Qe8 (10…Nh5 11.c3 Nxf3+ 12.Nxf3 Bxf3 13.gxf3 Nf4 14.d4 Bb6 15.Kh1! with 16.Rg1 to follow up and white is winning) 11.h3 (11.Re1 Qg6!; 11.Kh1 Qh5 12.c3 Nxf3 13.gxf3 Bh3 14.Rg1 Kd8 15.Rxg7 [15.Nc4 Ne8) 15…Ne8 16.Rg8 Rxg8 17.Bxg8 Qh4 18.d4 exd4 19.Qg1 Nf6 20.Qg7 dxc3 21.Nb3 cxb2 22.Bxb2 Ne8 and black has a slight advantage; 11.c3 Nxf3+ 12.Nxf3 Qh5 13.d4 (13.Be3 Nd7; 13.Bd2 Nxe4; 13.Bc2 Nxe4; 13.Bc4 Nxe4 14.dxe4 Rxf3; 13.h3 Bxf3 transposes to 11.h3) 13…Bb6 14.Qd3 (14.Re1 Nd7=) 14…Bxf3 15.gxf3 Qh3 16.Qd1 (16.dxe5 Ng4; 16.Rd1 Nh5; 16.Qe2 Nh5 17.Bg5+ Kd7 18.a4 [ 18.dxe5 Rxf3 19.e6 Ke8 20.Bh4 Nf4 21.Qb5+ c6 22.Qg5 Bd8 23.Qxg7 {23.e7 Bb6 leads to perpetual} 23…Bxh2+ 24.Kxh2 Rh3+ 25.Kg1 Ne2+ perpetual] 18…h6 19.Bd2 Rf4; 16.Bc2 Nh5 17.dxe5 (17.Bg5+ Kd7 18.Ba4+ Kc8 followed by h6!) 17…Rxf3 18.cxd6+ Kf8 19.Qe2 Rg3+ perpetual) 16…Nd7 and black has equality) 11…Qh5 12.c3 Nxf3+ 13.Nxf3 Bxf3 14.Qxf3 Qxf3 15.gxf3 Nh5 16.Kg2 Nf4+ 17.Bxf4 Rxf4 18.Rad1 Raf8 19.d4 exd4 20.cxd4 Bb6 21.Rd3 Kf6 22.Re1 Re8 23.Kg3 g5 and white cannot make progress in the endgame.

 

B1B: 8.Nc3! Qe8 (8…h6 9.Nh7!! Nxh7 10.Nd5+ Ke8 11.Qh5+ Rf7 12.Nb6!) 9.Nd5+ (9.d3 Qg6 10.Nd5+ Kd8 11.Nxf6 Rxf6 12.Nf3 Bg4 13.Bg5 Nd4 14.Nxe5 Qxg5 15.Ng4 Rg6 16.h3 Nxb3 17.axb3 h5 18.d4 hxg4 19.dxc5 gxh3 20.g3 Qxc5 21.Kh2 Rh6 and black has a slight advantage) 9…Kd8 10.Nxf6 gxf6 11.Nf3 Qg6 12.d3 and white is winning.

 

B2: 7.d3

 

B2A: 7…h6 8.Nf3 d6 9.h3 (9.Be3 Bg4 10.Bxc5 dxc5 11.Nbd2 Nd4 12.h3 Bh5 13.0-0 Nxf3+ 14.Nxf3 Qc8 15.Kh2 g5 16.Qe2 g4 17.hxg4 Nxg4+ 18.Kg1 Qe8=) 9…Qe8 10.Nc3 Nd4 11.Nxd4 Bxd4 12.0-0 Qg6 13.Kh2 Bd7 14.Be3 Bxe3 15.fxe3 Rae8 16.Qd2 and white has a significant advantage.

 

B2B: 7…d6 8.Be3 (8.0-0 transposes to B1A) 8…Qe8 (8…Bg4? 9.Qd2!; 8…Bxe3 9.fxe3 Qe8 10.Nc3 Qg6 11.Nf3 Bg4 12.Qe2 and white has a fantastic position with a pawn more) 9.Bxc5 dxc5 10.0-0 Qg6 11.Nf3 Bg4 12.Nbd2 and white is simply a pawn up.

 

B3A: 7.Nc3 Bxf2+ (7.Nc3 d6 8.0-0 transposes to B1B; 7.Nc3 h6 8.Nf3 d6 [8…Qe8 9.d3 Kd8 10.Be3] 9.h3 Qe8 10.d3 Kd8 11.Be3 Bxe3 12.fxe3 Qg6 13.Qe2 Qg3+ 14.Kd2 and white is winning; 7.Nc3 Qe8 8.d3 Qg6 9.0-0 d6 10.Nd5+ Kd8 11.Nxf6 Rxf6 12.Nf3 h6 13.Nh4 Bg4 14.Nxg6 Bxd1 15.Nxe5 Nxe5 16.Rxd1 Bxf2+ 17.Kh1 Kd7 18.h3 and white has a solid extra pawn in the endgame) 8.Kxf2 Nxe4+ 9.Kg1 Nxg5 12.d4 Nf7 11.dxe5 and white has a huge initiative.  It is doubtful black can survive.

C: 6...d6!?

This was my third attempt at trying to save black.  This was one of the best I have seen for black.  The only issue is that the move order is inaccurate which allows white to capitalize immediately.

7.Nf7! Qf8 8.Rf1 Rg8 9.Ng5-I have found no way around this line.

D: 6...Qe8!

Clearly, 6...Qe8 is the only move in this position.  This avoids the above line as 7.Nf7? would be met by 7...Rf8! with an advantage to black. 

My theory is still a bit thin on this variation as I have not had the time to go into as deeply as I would like.  My early analysis tells me that 7.d3, and 7.0-0 are equal.  I have not looked into 7.Nc3 yet, but I get the feeling it is critical.  Just some examples:

7.d3 d6 8.Nc3 (8.Be3 Qg6 9.Bf7 [9.Qf3 Nd4! and black has an advantage] 9...Qh6 10.h4 Bxe3 11.fxe3 Rf8 and black has an advantage) 8...Rf8 9.Be3 (9.0-0 Qg6 10.Nd5+ Kd8 11.Nxf6 Rxf6 12.h4 [12.Nf3 Bg4 13.Bg5 Nd4!] 12...h5 13.Be3 Bxe3 14.fxe3 Bg4 15.Qd2 Kd7 and white has a small advantage, but black has compensation) 9...Qg6 10.Nf3 Nd4 11.Bxd4 Bxd4 12.Qe2 Bxc3+ 13.bxc3 Bg4 and black has a slight advantage.

7.0-0 Rf8 (7...d6 8.Nc3 h6 9.Nf3 Bg4 10.h3 Bh5 11.d3 Rf8 12.Be3 and black is fighting for a draw in a pawn down ending) 8.Nc3 Qg6 (8...h6 9.Nf3 d6 [9...Kd8 10.d3 g5 11.Na4 Bd6 12.Be3 and white has a significant advantage] 10.d3 Bg4 11.h3 Bh5 12.Be3 Bxe3 13.fxe3 Kd7 and black is fighting for a draw down a pawn) 9.d3 d6 10.Nd5+ Kd8 11.Nxf6 Rxf6 12.h4 (12.Nf3 Bg4 13.Bg5 Nd4!) 12...h5 which transposes to 6.Bb3 Qe8 7.d3

13.c3 Bg4 14.Qe1 looks much stronger to me. I don't see a constructive plan for Black, but I do see a few for White.
Do you realize that 6...Rf8 7.0-0 Qe8 8.Nc3 Qg6 9.d3 is exactly the same?

6...Qe8 7.d3 d6 8.Nc3 Nd4 9.Nd5 Nd5 10.Bxd5 Qg6 11.c3 looks considerably stronger, but h6 might provide a playable game.
So possibly 9.Nd5 is not the strongest.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Bxf7+ Ke7 6.Bb3 Rf8 7.d3 d6 8.Be3 Bxe3 9.fxe3 Qe8 10.Nc3 Qg6 11.Nf3 Na5 12.Ba4 a6 13.b4 Nc6 14.Bxc6 bxc6 15.Qe2 Bg4 16.Kd2 Kf7 17.h3 Be6 18.Raf1 Kg8 19.Nh4 Qe8 20.g4 a5 21.bxa5 Rxa5 22.a4 c5 23.Qe1 c4 24.Qb1 cxd3 25.cxd3 Qa8 26.Qc2 Nd7 27.Rxf8+ Qxf8 28.Ke2 Nc5 29.Rf1 Qe8 30.Rb1 Ra8 31.Rb4 Qf8 32.Qb1 Bc8 33.Nf3 Ba6 34.Ne1 h6 35.Nd5 Qd8 36.Kd1 Kh7 37.Qc2 c6 38.Nb6 Ra7 39.Nc4 Qf8 40.g5 Rf7 41.Nd2 Rf2 42.gxh6 Rh2 43.hxg7 Kxg7 44.Rb6 Qe8 45.Kc1 Rh1 46.Nf1 Qg6 47.Qe2 Rg1 48.Rxc6 Qf6 49.Rxa6 Rxf1 50.Rxd6 Rxe1+ 51.Qxe1 Qxd6 52.Qg3+ Kf7 53.d4 Nxa4 54.Qxe5 Qxe5 55.dxe5 Nc5 56.h4 Nxe4 57.Kc2 Ke6 58.h5 ½-½

If 8.Be3 is White's best I would not call the Traxler refuted yet: 5.Bxf7+ Ke7 6.Bb3 Qe8 7.d3 d6 8.Be3 Bxe3 9.fxe3 Bg4 10.Nf3 Qh5 11.Nc3 Rhf8 and it won't be easy to convert the extra pawn. Not that I would like to play this as Black.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

A few years ago Ari Ziegler posted an article in swedish magazine "Tidskrift för schack" about Two Knights defence when Traxler where feutured. I think he concluded that Bxf7 was a clear safe pluss for white and that computer had found something for white even in Nxf7 lines. Unforutanlly I dont remember the number or where I put that magazine.


Indeed I've said it before and I'll say it again. It's not even worth consideration until a Traxler devotee shows me what he's got against the ridiculously simple Bxf7-b3 systems with d3. It's simple and perhaps objectively best.

Black has little hope of equalizing in the Qe8 lines. Here is a game in 5 against Fritz 10. Obviously White could have tried to win this but took the draw instead.

5.Bxe7ch Ke7 6.Bb3! This is simply better for White because Black has nothing better than to exchange off the Bishop on b3 with either Nd4 or Na5. The main point being that it seems pointless to play Bd5/Bxc6 if you're just to going to exchange Bishop for Knight anyway.

6...Qe8 7.d3 Kf8 8.Be3 Bxe3 (It doesn't really change matters here to play Bb6 9.Bxb6 axb6. The open a-file is at best a wash for the damaged pawn structure) 9.fxe3 Na5 10.Nd2 Nxb3 11.Nxb3 d6 12.Nf3 Kf7 13.Nbd2 Rf8 14.Qe2 Kg8 15.a3 Be6 16.b3 Rd8 17.c4 Qg6 18.O-O Qh6 19.Kh1 Ng4 20.Rae1 b6 21.Kg1 Qg6 22.h3 Nh6 23.Kh1 a6 24.Rf2 Qg3 25.Nf1 Qg6 26.Nfd2 Qg3 27.Nf1 Qg6 28.Nfd2 Qg3 1/2-1/2.

Obviously, only White in the final position has winning chances. Instead of 28.Nfd2, White could try Ng3/R1f1 followed by trying to get a passed pawn on the Queenside. I thought it would be difficult to avoid a tactical mishap once files start to be open on the Queenside. At a slower time limit it would be judicious to explore Queenside expansion with ideas like either d4 or c5. According to Fritz after that move sequence its evaluation is +/-.


Of course if black plays very bad move white is winning!

6...Qe8 7.d3 Kf8?? (even Rf8 is bad 7.-d6 id correct IMO
