Korch,

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 Qf6 5.Nc3 Qf7 6.Ne3 d5!? 7.Nexd5 Be6 (instead "Conquistador" 7..c6) and now Bucker points after 8.Bc4 Na6 9.b3!? "it might be difficult for Black to achieve full compensation" ...

After 9...Bc5 10.0-0 0-0-0 11.Bb2 Bd4 12.Ne3 Nc5 Black`s position seems to be not so bad.


11.Ne3 Bxc4 12.bxc4!? is not a bit risky with "b" open file? ...

After 12...Nf6 I don`t think that White pieces are too well placed to exploit it.



12..Nf6 is impossible, so the Queen is on "f6", so perhaps 12..Qg6 13.Rb1 (or 13.Bb2) then -both- 13..Nf6 etc.


                    And what's about Classical Main line with 3.Nxe5 Qf6 4.d4 d6 5.Nc4 fxe4 6.Nc3 Qg6 7.f3 exf3 8.Qxf3  ?. In this key position:


                    1a) 8..Nc6 9.Nb5! Bg4 10.Qc3! threating on "c7" was already pointed by Kosten. In his book there are some games with 10..Rc8, 10..0-0-0 and 10..Kd8 all dubtious for Black, but I remember strong CC player Peter Leisebein suggested 10..d5!?; now "natural" 11.Nxc7+?! Kd7 etc. had success as Black in three games, but finally was refuted in a good way in Melchor-Zielinski, corr.,LADAC thema (sf.), 2008/09 with 11.Bd3! etc. 
 
                    1b) 8..Nf6 has been totally discredited by 9.Ne3! ( instead less clear and more known 9.Bd3 ) in later games. White decides to make "g4" unavailable for exchange the Queens, and Black play is totally passive. There are many games with this moves sequence
 
                    1c) 8..Qg4!? is less known and played, buy It was reccomended by myself. Kosten only analyzes 9.Qf2 ( I don't think exchanging Queens is good for White ) 9..Nf6 10.Be2 and now instead of Kosten's 10..Qe6?! I suggest 10..Qg6!?; In this order, THERE ARE NOT ANY GAME still played ( only traspositions, so they are very important ! ). Some examples:
 
                     11.Bd3 Qh5 12.0-0 Be7 (or 12..Nc6) 

                   *13.Ne2 0-0 14.h3 Nc6 15.Nf4 Qe8 (15..Qf7) = Fleischmann-Cano, corr., 1970 by trasposition

                   *13.Be3 0-0 14.h3 (14.Qg3 Nc6 15.Rae1 Bd7=) 14..Nc6 15.Qg3 Be6 = Gaard-Müller, corr., 1988/89 by trasposition 

                   *13.Bf4 0-0 14.h3 Nc6 15.Rae1 Bd7 16.Ne3 White has more space, but Black is solid (Kosten)-- Bergsma-Wijnands, Rotterdam, 1939 by trasposition 1/2-1/2 in 60 moves)

                   *13.Bd2 0-0 14.h3 Nc6 15.Qe3 Bd7 16.Rae1 Rae8 17.Ne2 1/2-1/2 Hewitt-Thornton, 1998, also by trasposition.

                   *13.Bd2 0-0 14.h3 Nc6 15.Rae1 Bd7 followed by ..Rae8 = Knostenbergs-Melchor, corr., 2001/02 (1/2-1/2 in 31 moves)

                    White can try15.Ne3 or Qg3, but they may be met by15..d5.

                    So perhaps White has to try for an improvement earlier. Ideas?, maybe 13.Nb5!?; 11.Ne3!?


                    Last times many players - as I myself - have tested 7..Be7!? to re-evaluate whole variation. Although we have got nice positions after 8.fxe4 Nh6! - or 8..Nc6 and 9..Nh6 -, I'm not sure about it if White plays 8.Nxe4 or 8.Ne3!?

About 7...Be6 - I feel black might face problems after 8.Bc4 Na6 (I don`t see anything better as 8...Bd6 fails to 9.Qe2) 9.Bxa6 bxa6 10.Ne3 Nf6 11.f4!

OK Conquistador, good work !. I see that you know several games with this move ... and that you want to refute the gambit as White at full speed ! ( By the way, I can also read you in www.chess.com, but I have problems on registering )

Thus, we reject again 5..Qg6 and we must to go back to 5..Qf7 6.Ne3 d5!?. We will need some time to improve ideas by Stefan Bucker in http://www.chesscafe.com/text/kaiss44.pdf. Their analysis was not very detailed, I am not entirely agreed and additionally, it needs to be tested in practice ( Thus I have already material to try as Black in the Final of next World Tournament of gambit in February ! ). Ideas ( please, for second player ... so I will need for the Tourney ... Smiley ):


7.Nexd5 (7.Ncxd5 Be6! 8.Bc4 Bd6 etc. Melchor-Ardila, cr. email LADAC thema sf., 2008/09 was quoted by Bucker as playable for Black ) 7..c6 8.Ne3 Nf6 9.f3!? ( Bucker ) 9..exf3 10.Qxf3 Be6 11.Be2 Nbd7 12.d4 0-0-0 ( or 12..Bd6 choosing short castle ) and as in other lines on LG, Black has chances to exchange the kingside pawns and draw the resulting 4 vs. 3 on the queenside situation. Similar variations it has been played often in this way - Black always with pawn down - but without excessive problems for drawing ( at least in postal chess with Nalimov Tablebases ).

Hmm... we see if finally I MUST CHOOSE 3..Nf6!? !!  Grin
 


In my opinion 7...Be6 can be played also after 7.Nexd5. 7...c6 seems to be dubious.

P.S. Oops... Buecker has already mentioned 7...Be6 as move he would prefer.  Smiley

Stefan you gave the line:

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qf7 6.Ne3 d5 7.Nexd5 c6 8.Ne3 Nf6 9.f3 Bc5 10.Be2 exf3 11.Bxf3 0-0 12.0-0 

and white is clearly better.

What about 10...Nc6 instead of 10...exf3 ? After 11.fxe4 Bxe3 12.dxe3 Rd8 13.Bd3 0-0 14.0-0 Ne5 Black should have compensation for the pawn.


10..Nc6 its is an impossible move, so 7..c6 was played at 7th. move ...

My mistake - I thought that 7...Be6 was played  Lips Sealed

Well, according to all these moves, 6..d5 not resolve Black play either, so we should put one's trust in the following line pointed by Stefan with 3.Nxe5 Nf6 :

4.Ac4 Qe7 5.d4 Nc6 ( by transposition we are in the Morgado System ) 6.Nc3 Nxe5 7.dxe5 Qxe5 8.0-0 returning the pawn, but opening the position and leaving the Black King and Queen in the same row. Now, instead of Kosten suggest 8..Bd6 9.g3. fxe4  wherever White reply 10.Re1 Kd8 11.Nxe4!; correct move-order is  8..fxe4 9.Nd5-  threatening Bf4 – 9..Nxd5 10.Bxd5 Bd6!? ( 10..c6 11.Bxe4 was already pointed by Hagen Tiemann; now f.i. if 11..Bd6 12.f4!? ) 11.g3 ( 11.f4 Bc5+ 12.Kh1 Qd4 solving all problems in Fragola-Valverde, corr. LADAC thema, 2006 ) 11..c6 12.Bxe4 0-0 13.Qd3 h6 ( Stefan Bücker ), when Black can probably hold an uncomfortable but playable position: 14.c3 Qf6 15.Be3 Be5 16.Bh7+ kh8 17.f4 Bc7 18.Bg6 Bb6 19.f5 d5 20.Rae1 Bd7 (Rybka3)

Je,je, if Latvian has been finally refuted with "drawing pen", we should change to the Philidor Countergambit. There is a terrible debate between James West and Dennis Monokrousos in internet too !?  Cheesy , but paradoxically it has not been analyzed deeply in this forum

I think that the exchange on f3 looks positionally strong for white.  Black looks to be in a bind.

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 Qf6 5.Nc3 Qf7 6.Ne3 d5 7.Nexd5 c6 8.Ne3 Nf6 9.f3 exf3 10.Qxf3 Be6 11.d4 Bb4 12.a3 Bxc3+ 13.bxc3 Nbd7 14.Bd3 and white has a solid advantage.

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 Qf6 5.Nc3 Qf7 6.Ne3 d5 7.Nexd5 c6 8.Ne3 Nf6 9.f3 exf3 10.Qxf3 Be6 11.d4 Bd6 12.Bd3 Nbd7 13.0-0 0-0-0 14.a4 Rhf8 15.a5 Qe8 16.Qe2 and white has a significant advantage.

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 Qf6 5.Nc3 Qf7 6.Ne3 d5 7.Nexd5 c6 8.Ne3 Nf6 9.f3 exf3 10.Qxf3 Be6 11.d4 Bd6 12.Bd3 Nbd7 13.0-0 0-0 14.Nf5 and white has a solid advantage.

Yes I am on chess.com.  I like the community and the correspondence games.  Probably the only thing of importance I have done there was my work on the Traxler, but that is for another thread.

Ironically enough, I was looking at that exact variation as the only way I could find a solid advantage for white.

Personally, in this variation I would not put my light square bishop on e2 as it has no influence!  In this position white needs to control e4 and e5.  So white needs to play d4 and Bd3.

1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qf7 6.Ne3 d5 7.Nexd5 c6 8.Ne3 Nf6 9.f3 exf3 10.Qxf3 Be6 11.d4

Now for a sample line

11...Bb4 12.a3 Bxc3+ 13.bxc3 Nbd7 14.Bd3 and white looks strong and can focus their attack on the kingside or queenside depending on where black castles.

Now you mentioned in the line 1.e4 e5 2.Nf3 f5 3.Nxe5 Nf6 as a possibility.  4.Bc4 looks pretty strong to me threatening Nf7 forcing more concessions.

In my investigations, I found that in the line:
1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qg6 

Instead of 6.d3, 6.Nd5 seems better.

6.Nd5 Kd8 (6...Na6 7.d4 Qf7 8.Nce3 c6 9.Bxa6 cxd5 10.Be2) 7.d4 d6 8.Nf4 Qf7 9.d5
