Here is some very brief analysis that needs much more work:

I suggest that we move on to analyzing the Breyer.

I think two lines might be necessary because the Breyer is extremely solid and having two lines so that we can mix up our choices might be good. 

I like the 14. Bg5 line and I think it deserves more attention.

Hello.

To get an overview of what has been analyzed i took to counting the pgn:s that have been produced so far in this thread, while also noting which line they were about.

#number indicates posts in this thread. For example #60 means there is a PGN in post number 60.

(1.e4 e5 2.Nf3 Nc6 3.Bb5 f5) 
#60, #144, #191, #308, #348, #351, #362, #447

(1.e4 e5 2.Nf3 Nc6 3.Bb5 a5)
#99

(1.e4 e5 2.Nf3 Nc6 3.Bb5 Bc5)
#189

(1.e4 e5 2.Nf3 Nc6 3.Bb5 Nge7)
#209

Summaries
#217, #222, #265

(1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0)
#229

(1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d5)
#396, #400, #404, #413, #417, #427

(1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.h3)
#439

(1.e4 e5 2.Nf3 Nc6 3.Bb5 f6)
#452 

It seems the Jaenisch is what has been getting the most attention, while actually the mainline-esque Marshall has been getting som decent coverage also.
Which lines have reached a point where they can be deemed to have been analyzed sufficiently I don't know. 
I think I will look into if the Jaenisch coverage is sufficient and post a Jaenisch specific PGN.

Have a nice day.

Sounds like a fair way to approach the problem to me.  Grin

Also, what is the actual goal? I mean, at least for me, if you analyze anything deeply in enough, you'll likely find equality for Black in every line of the Ruy Lopez - I doubt 1.e4 e5 2.Nf3 Nc6 3.Bb5! is a forced win for White!
 
Your belief (a very reasonable belief, imo) isn't necessarily a contradiction to Markovich's approach. In reply #19 he said the following: 

Markovich wrote on 07/24/11 at 20:32:44:
I don't say we should try to prove +=.  I say that our starting assumption should be that with best play, that's what White gets. If we find ourselves with less at some point, this will indicate we should either look deeper or change approaches.

So I believe that with this, which is Principle #4, and Principle #1, we already have a complete set of criteria for selecting White's moves. As for Black's, we are compelled to consider any that do not obviously result in += or better for White.

If += isn't realistic, call it as you prefer. Initiative? A little something?

Well, I understand what Stefan wrote in the previous post. But what you write is... ah, forget it.

Have you ever taken a closer look at the development of opening theory? You think your own behavior would have changed  anything in that development course? Would you have been a part of the indian evolution on 1.d4? Would you have found 3...a6 in the Slav worth playing? Would you have actively taken part in the development of say 3...c6 or 3...e5 in the Pirc? No, would you have accepted the Pirc at all?

When looking back in theoretical development: when would it have been time for you to quit the flow of sideline novelties to save the "mainlines"? Perhaps before Breyer's irritating jump back with Nc6-b8 in the Lopez?   

To change a question of your own:  Do you think you would have the slightest chance playing a top GM if he would play the ridiculous moves 3...a5 or 3...f6 against you?! 

Nevertheless I wish you the best in discussing main lines. There too are loads of novelties but that allways need an open mind...

I would be happy to trot on (I did little to nothing in the first wave, but I was working on my book), but perhaps someone needs to organize an update on the status of the lines examined?

Also, what is the actual goal? I mean, at least for me, if you analyze anything deeply in enough, you'll likely find equality for Black in every line of the Ruy Lopez - I doubt 1.e4 e5 2.Nf3 Nc6 3.Bb5! is a forced win for White!

This thread should continue in the spirit of the late Markovich, imo. May he rest in peace. We had our disagreements, but he wasn't shy of discussing offbeat lines. What we agreed on was that there must be someone who gives the talk a direction. Someone saying at a certain point: "we should stop here, this is '+=' enough for me. Let's move on to another line." That moment would have come relatively early with 3...f6, I guess.

I'm a bit confused why to first save e5 with f7-f6 and than to surrender that strengthened point with e5xd4 (your suggestion 14...exd4). Well yes, Nimzovich's "Sägestellung" against pawn e4...

It's hard for White to attack Black's structure c6, d6, f6, and there is enough room for black counterplay. Similar to the misjudged Englund Declined. As in "anything goes, I can even decline the Englund and keep a solid plus".

Hi.

Quote:
Why are people asking questions about moves like 3... a5 and 3... f6?

Basically, for better or worse, because no one has pushed through rules preventing discussion and analysis of highly offbeat tries.

Quote:

No.

Quote:

This... 
or 
Continuing with analysing black's various 3rd moves...
or
Checking lines already looked at.

Either way I think consolidation of results before moving on is very important (I don't think baking a mega PGN is enough on its own here).

Have a nice day.

I wonder whether I ever looked at 3...f6 again. Thought the analysis was in the same file as 3...Bb4, but there was only 3...Rb8!. [...] Basically my idea was: "static defences" like Qxf4 followed by d6 and f6 in the King's Gambit work, as what can White do? A few years later I understood that the answer to this rhetorical question was: White can do a lot. Even if the first move were OK, after 14...Nef4 followed by h5-h4, White has a ton of possibilities. I still can't find a clear refutation, but the whole concept is clearly very optimistic. 

A few years later, after working on the Englund Gambit, I might have recommended 14...exd4! instead. The arrangement of pieces and pawns in the center is really similar to the Englund.


Yes that is the point of Steinitz' artistic, irritating, sometimes ridiculous approaches on his strongpoint e5 concept. He had quite some tries on that very subject, the one or the other even ending in complete reocupation of his back rank with his pieces...

But in fact f7-f6 takes at the earliest possibility the sting out of the spanish concept - the weakness e5 is covered.

This idea reurns in the Modern Steinitz Defence, Alapin Variation: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 5.Bxc6 bxc6 6.d4 f6 (C73). Is it to bad?!

I'm a bit confused why to first save e5 with f7-f6 and than to surrender that strengthened point with e5xd4 (your suggestion 14...exd4). Well yes, Nimzovich's "Sägestellung" against pawn e4...

Stefan Buecker wrote on 12/24/15 at 12:31:11:

Whether all this is relevant at all for the assessment of 3...f6, I have my doubts... Several moves of Tarrasch were "pragmatic" (a3, Bc4, h3, Kh2), not necessarily the most challenging in a theoretical sense. So if the opponent is not a very strong player, maybe it can work.


Pragmatic, yes. After f7-f6, the Bb5 has played his mayor role, or am i wrong? Yes, due to the pin of the Nc6 he further put's a question to the ideal d7-d6 (but more than once that never the less may work as there are a7-a6 and b7-b5 to break the pin). Returning to c4 is natural, but a tempo down to the Italian (but a weakness up on a2-g8 - but is this too relevant?!). a2-a3 saves the italian like bishop (against Nc6-a5) and h2-h3 is... normal Lopez, isn't it.
The pragmatism bases on the work of the strongpoint e5. I don't see how this can be overruned. What are those challenging moves?!   
Browsing through Steintz' games with the strongpoint e5 concept he more than once ended in a sort of king's indian structure. 
He had not too much luck with it, which may have its reasons in the exhaustive backward tended play - as for example Tarrasch - Steinitz shows. 
At the end he surrendered the exaggerated attempts on it. May be a sign...
But as you Stefan showed with your 14...Nef4 idea there are more active concepts - which in return give white some prospects for play. "White has a ton of possibilities", well that is a bit much of it...

Stefan Buecker wrote on 12/24/15 at 12:31:11:

For a "theoretical" discussion, the Marshall Gambit should be a priority, but final conclusions are not easy to see. Presently I think Black is fine.


No, no that is not you Stefan.That is perhaps Max Euwe of the 1950s. Not only some selected main variations count... Not today.
Shall we really confine ourselfs to search for novelties in move 38 or later??

Remeber after all: Even Magnus Carlsen once played the North Sea Defence (1.e4 g6 2.d4 Nf6 - okay that's another topic but quite offside as well) against Aronian if I am right. He got his share of played, but lost, but not due to the opening.

Actually, I do not see the point behind f6 in the relatively simple line 1. e4 e5 2. Nf3 Nc6 3. Bb5 f6 4. d4 and no matter wether Black takes to times or only one time (as let White get d5 in would trouble Black a bit) White should have a comfortable edge due to the weakening of the Black kingside and the lead in development.

The game Tarrasch - Steinitz shows that Steinitz was willing to play the position after d4-d5. So if 4.d4 Nge7 5.d5 a6 6.Bd3 Nb8, what do you get what you wouldn't in Tarrasch's move order? On the other side, 4.d4 gives Black a serious additional option in 4...exd4 5.Nxd4 Nxd4 6.Qxd4 Bd6, e.g. 7.Bc4 Ne7 8. Nc3 Be5 9.Qd1 c6 10.0-0 b5 11.Bb3 a5 12.a3 Ba6. Maybe 13.Qh5+ is good for White, but this kind of tactics can't be the "clear refutation" that you'd want.

As Stefan ist back on the scene, I take the opportunity to just repeat my last post, which was directed to him and stands unanswered.

What about 3...f6!??! in the Lopez?!
See previous post for details.
Thx and merry christmas.

I wonder whether I ever looked at 3...f6 again. Thought the analysis was in the same file as 3...Bb4, but there was only 3...Rb8!. Now I have to leave for Christmas festivities, so right now this has to suffice.

to avoid confusion, I'd write it like this:

"3...f6 - ?"

Write it as you like.

I tried to avoid that the move 3...f6 gets the question mark that is simply given as the normal mark at the end of a question...

As pointed out I'm at least not sure about this move. But Stefan had it in a quite positive conotation in the given source...
