For Markovich to suggest that Black is fine after 3...Nf6 ignores analysis known to him.

Just like you do - on this forum it has been shown that in the Fritz-Ulvestadt 9.cxd4 instead of 9.Ne4 is quite close to a refutation and therefor is superior to "the incredibly complicated 9.Bc4", after which I would not mind to have Black.
Notice that you yourself admit that 3...Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Qf3 Be7 is equal. Thus your reproach is unjustified.

I agree with him, I think Black is fine after 3...Nf6, which is why I have always preferred it to 3...Bc5. It is good objectively, and also subjectively as my OTB experience indicates that very few players feel happy playing 4 Ng5 and having to defend. Instead almost everyone I play prefers to play something with d4 and achieve lost positions with White very quickly!
Smiley So from a repertoire viewpoint it is clearly a problem for anyone playing the Evans.

I don't understand Markovich's reasoning either. 3.-Bc5 and 3.-Nf6 are two different commonly played defences. One could just as well state that the "problem" with the Ruy Lopez is the Petroff, which is rather irrelevant once Black has played 2...Nc6. Or that the problem with 1.e4 is 1.d4! With that line of reasoning you'll just end up like Buridan's donkey...


The emphasized statement certainly is not analogous to what I said, since 1.d4 isn't an opponent's move.  

Pardon my imprecision, though.  It seems that I invited quibbles by not spelling my point out in A, B, C fashion.  So let me say, A significant problem for a repertoire founded on the Evans Gambit is that you will very often see 3...Nf6, which is fully adequate for Black and which completely frustrates your desire to play in gambit fashion.  That is what I thought I implied by my saying "from a repertoire standpoint" and by my implicit recommendation of the Two Knights.

If I considered the Petroff to be fully adequate for Black I would agree that that defense is an analogous problem for a repertoire founded on the Spanish, but I do not.  But there are many who think that the Petroff is indeed a problem for would-be Spanish players, so that claim must at least be arguable.

So I modestly claim that I actually did say something.  Maybe it wasn't quite on-topic, but since it was in response to a post in the vein of "Hmm, should I take up the Evans?" it seemed appropriate.

If someone wants to base his repertoire on the Evans I wish him well.  If he tries 3.Bc4 against me, though, he will see 3...Nf6.

There is a vast amount of literature on line in Chesspub and chess.com in the 3...Nf6 variation and White can practically "force" Black to play a gambit after 3...Nf6 4.Ng5---the Wilkes Barre is dead after 4.Ng5 Bc5 5.Bxf7ch Ke7 6.Bb3+/-   

4.Ng5 d5 5.exd5 Nd4 6.c3 b5 7.Bf1 Nxd5 8.Ne4 Ne6! (Qh4?---the Berliner Gambit---9.Ng3 Bg4 10.f3 e4 11.cxd4 Bd6 12.Qe2! Be6 13.Nc3! +/-) 9.Bxb5ch Bd7 10.Bc4! is incredibly complicated where the better player will win. 

The Ulvestad (5.exd5 b5 6.Bf1) has minimal independent significance because it usually transposes to the Fritz,

The Fried Liver is the only way for Black to avoid being down material yet this exposes Black to a GAMBIT that most players don't like to meet.   

The variation 4.Ng5 Nxe4 5.Bxf7ch is +/=   

Black has maybe drawing chances in the main line after 4.Ng5 d5 5.exd5 Na5 6.Bb5ch c6 7.dxc6 bxc6 8.Qf3 Be7 is the only real try for equality; all the other variations favor White (the analysis is on line) & finally after 5.exd5 Na5 6.Bb5ch Bd7! gives White only the first move advantage i.e. a tiny plus.

One reader indicated that because Black can equalize in the main line in the 8.Qf3 variation that I hadn't proven that White had an advantage against 3...Nf6 i.e. he apparently believed that White had the advantage in all other variations!

For Markovich to suggest that Black is fine after 3...Nf6 ignores analysis known to him.

thanks for finding that post would've never spotted it.

Isn't that the old Short-Nielsen game that was published in Informant I think. Sure Short himself came up with a convincing improvement for White which put Black on the critical list, will post it once I get a chance to look it up.

Edit: ahh I cant post anything because there is too much. This game was annotated not only by Short but by Luke McShane it seems, and someone else also. McShane is very enthusiastic for White saying the bishops "dominate the board" but I see no clear win. I think people will have to look up this game because its a great game, but I dont think ultimately its a line that will put the Evans out of business.

No, good point.  As far as analysis goes I only found this mention with the 7.Qb3 Qe7 variation (instead of 7...Qf6):

Quote:

"I also find his comment in the following line very superficial while at my opinion this concerns again an important mainline.
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 exd4 7.Qb3 Qe7 8.0-0 Bb6 9.cxd4 Nxd4 10.Nxd4 Bxd4 11.Nc3 Nf6 12.Nb5 and here Marin stops saying white has a strong initiative. However I think white really has to do his best not to run out of steam and fall in a bad position. 12... d5 13.exd5 Bxa1 14.Ba3 Qe5 15.f4 Bd4+ 16.Kh1 Qe3 17.Nxd4 Qxb3 18.Re1+ Kd8 19.Be7+ Kd7 and i prefer to play with the extra exchange.", Brabo.

Well done brabo.  This makes a lot of the analysis on this thread obsolete.

Even Gustafsson on his DVD admits the Evans is a dangerous choice which is why he opted for the solid looking 5... Be7 6.d4 Na5. This has it´s logic of course but putting the Knight on the rim does not look so appealing to me here. 

Has there been any improvements for White in the lines after 5... Ba5 as given by Marin in "Beating the Open Games"? As far as I remember this leads to equality but White has to know his stuff as well as Black. One of my games went 5... Ba5 6.d4 exd4 7.0-0 Nge7 8.Qb3?! 0-0 9.cxd4 Bb6 10.Qd1? d5 and I was able to score an easy point.


Because of that white plays after 5. ...Ba5 6.d4 exd5 7.00 Nge7 now 8.Ng5! and now 8. ...d5 (8. ...00 9.Qh5 of course) 9.exd5 Ne5 (9. ...Nxd5? 10.Qf3 of course) 10.Qxd4! f6 (10. ...Nxc4? 11.Qxg7 Rf8 12.Nxh7 +/-) 11.Re1! and I would prefer white
Play could continue: 
11. ...Bb6 12.Qh4 fxg5 13.Bxg5 N5g6 14.Qh5 Lc5 15.d6!

White is down material but has a lot of compensation

Not sure this is important now but Kaufman recommended "the alternative move order" 8...Ne5 9.Bb3 to avoid the 8...d5 9.exd5 Ne5 10.Qxd4 variation.  It's on page 287 if you have his The Chess Advantage in Black and White.


Please recheck the strong thread of : http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1174123573 and let me know if there are any improvements found for white.

Also http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1282333110/0 has some valuable info on the Evans Gambit.

So what's the current verdict on the Evans Gambit declined? (i.e. 4 b4 Bb6).  If white plays c3 it transposes to the 4 c3 Nf6 5 b4 Guico Piano, so can white take advantage after 4 b4 Bb6 5 a4 a6 6 Nc3 Nf6 7 Nd5 Nxd5 8 exd5 Nd4?

Good point - your analysis looks right to me, which means this should be the "main-line" in Marins branch rather than the line he gave. The whole line is quite obscure since Marin is trying to invent a new defence anyway. Interesting stuff, I think I might try to improve earlier for White, will have a look.....

Grabbing the pawn needs to be checked I agree, but seems optimistic.


Hm, I have analysed some sample lines after 15.Ne5 Qf6 and wasn´t able to find something convincing for White:



Unless someone finds an improvement for White 12.Ne2 does not seem to work out so well. At least taking on e4 is surely the most testing answer.

If you can show us how White can play for an advantage after 3...Nf6 4.Ng5 d5 5.exd5 Na5 you will make a lot of people happy.


Well, I'm out of touch then, because I was under the impression that 4.Ng5 was doing quite well against the Two Knights' (and indeed I changed to 3...Bc5 some years ago because of this). Can anybody perhaps point me to a thread where I can be enlightened?

I find the Evans' quite testing to play against, by the way, though my record against it is won two, lost two.

Thats it, you're right its level on material, just a bad structure he says, but I prefer White. Grabbing the pawn needs to be checked I agree, but seems optimistic.
