  centralfiles: <AK><<<centralfiles> I would frame the argument as follows ... Then why would we assume that white might be winning after 19...Rf6?> We can't. But neither can we assume that White is <not> winning. There are simply too few (I think) analyses (samples of the all the possible "reasonable" lines) to reach that conclusion. And I haven't yet figured out how to determine the number of analyses that would need to be done in order that the conclusion we reach is statistically significant. It could be a lot!> I don't really know what to make of this.
If all lines the engines are evaluating as possibly winning <+.7 or higher for arguments sake> can be shown to actually peter out to a draw<less than +.5> with best play, then we are left with lines the engines are evaluating as drawish why would we assume that some +.41 line is actually winning? it's seems terribly unlikely. Statistical analysis of lines evaluated at +.7 or higher doesn't seem necessary, they can individually all be shown to peter out to lower evals or provable endgame draws for human analysts.

  centralfiles: <AK> <Probably because no one seems to have anywhere near the fervor in favor of 19...h6 leading to a draw that you and <kwid> (and possibly others) feel that 19...Rf6 leads to a draw. So the effort that has been spent to "show" that 19...h6 (or any other 19th move by Black for that matter) leads to a draw is nowhere near as much as has been spent to "show" that 19...Rf6 leads to a draw.>

Lest we forget that ...h6 was actually played. Neither team found a line that might draw, nor did subsequent engine analysis find any real improvements for black. At the same time no one has yet been able to show a line after ...Rf6 where black doesn't seem to be holding on to the half point though some posters might have dropped some obfuscating posts that imply otherwise without providing any analysis. (only real attempt to show win for white was by Ceri but those lines petered out to draw as well <Ceri was unfortunately given inferior black moves to analyze>) I don't understand how this little fact can be ignored.

  centralfiles: <About the only anywhere near overwhelming evidence that tournament provided, I believe, is that after 24 games were played, Black was not able to win even once. While this may also not technically be "conclusive" either, it does seem that if Black has any expectation of winning, improvements for Black need to be found between 5.Bxf7+ Ke7 and 20.Nb5. Because, why would you play the Traxler if the best you can hope for is a draw?>

You play the traxler for the same reasons you play other gambits - great results against players that are not great with their king under pressure and not booked up to the hilt. The real Question of this whole exercise was more whether Black is busted theoretically or not.

Though in a practical sense I would agree black is somewhat busted even though 19...Rf6 is a draw. With 8.b4 White has successfully turned the tables with black being the one under pressure to defend accurately. It's hard to imagine anyone wanting to play these positions OTB as black.

  centralfiles: <AK><I agree, that's what I've been saying all along. The position after 20.Nb5 is extremely complex as is the Traxler in general. So to "conclusively" prove anything is at least very hard, and possibly impossible. The best we could hope for, I think, is to show that a particular move at a particular position leads to the desired result in a statistically significant way to a level of confidence we can live with, and accepting the non-zero margin of error in the estimate.>

I can't imagine <KWID> means "conclusively" as 100% definitive mathematical proof.

  AylerKupp: <<centralfiles> As was said earlier the engine tournaments serve almost no purpose here. If the black side deviated at all form our analysis the result is just about worthless.>

Well, I certainly disagree. It may not be conclusive but it gives some indication, statistically speaking if you play enough games, of Black's drawing chances. If you keep an open mind and try different moves at different stages of the game, it will give you some idea of what moves work better than others as far as results are concerned.

<If all lines the engines are evaluating as possibly winning <+.7 or higher for arguments sake> can be shown to actually peter out to a draw<less than +.5> with best play, then we are left with lines the engines are evaluating as drawish why would we assume that some +.41 line is actually winning? it's seems terribly unlikely. >

You don't need to restrict the analyses to lines evaluated as possibly winning, best to look at all lines. And lines that originally did not seem to be winning could, depending on how deep you search, could indeed turn out to be winning. Again, not likely, but you just can't rule them out.

  AylerKupp: <<central files?> Lest we forget that ...h6 was actually played.>

Sure, but afterwards it was not subjected to anywhere the depth of investigation that 19...Rf6 was. There were no champions for 19...h6 like there were for 19...Rf6. For all we know if 19...h6 had been subjected to the same level of analysis as 19...Rf6 it might have also shown that all lines petered out to a draw. And just because Ceri wasn't able to show a win for White, given the limited scope of his analysis, that again doesn't mean that the win wasn't there.

So I don't think that this little fact was ignored, it was simply the fact that no one really cared a lot about showing a certain win for White, so the matter was dropped due to lack of interest.

<Though in a practical sense I would agree black is somewhat busted even though 19...Rf6 is a draw.>

Ha! You and <kwid> can keep on insisting that's the case until the cows come home but that doesn't make it a fact. Given the limited number of lines that have been analyzed compared to the number of reasonably alternative lines there is no conclusive evidence as far as I'm concerned that 19...Rf6 leads to a draw or, for that matter, that it's superior to 19...h6 as far as providing Black with the best practical chances for a draw. 19...h6 has simply not been investigated anywhere as thoroughly as 19...Rf6 by anyone who has the same motivation as you and <kwid> have to insist that 19...Rf6 leads to a draw.

  AylerKupp: <<I can't imagine <KWID> means "conclusively" as 100% definitive mathematical proof.>

Me neither, but that's a question to ask <kwid> as to what he meant. I personally would not expect a 100% definite mathematical proof but only that the conclusion (whatever that is) is statistically significant. The most typical answer to what that means is a 95% confidence level that the result was not due to chance; i.e. a 5% or ± 2.5% that it could be.

Exactly what that means in this case, if anything at all, I'm not sure. Confidence levels are typically used when the data (population) that you are looking at is Normally distributed and you sample that population at random. And I have not been able to come up with a was to cast situations like this into a situation like that. Clearly the analyses will not be selected at random although, if you have enough analyses, they could theoretically be. And I don't know if the analysis results can be considered Normally distributed since there are only 3 of them; White wins, White loses, or the game is a draw.

So, to be frank, I don't know how to use the term "Confidence Level" in this situation other than intuitively, although I would not require that 100% of a "significant" number of analyses indicate that the result was a draw to accept that hypothesis.

As a reminder, I'll be out of town for a few days so my ability to respond will be limited. So don't feel that I have lost interest if I don't respond to anyone's posts in a timely manner. I'll be taking a probability book with me (no joke!) so maybe by the time I come back I'll a better ideas of how to deal with the problem. I know, I have to get a life.

Sounds to me like you may have been absent during the game it was analyzed quite extensively. Do you any possible improvements?

Nov-21-18
Premium Chessgames Member
  AylerKupp: <centralfiles> Yes, I was absent for the greater part of the game. I glanced through the comments after the game and the number of analyses of 19...h6 did not strike me to be nearly as many as for 19...Rf6, particularly after the game ended. So I will review the posts once I get back home and compare their relative number and, if I can, their quality.

  kwid: <AylerKupp:> The arguments before us as I see it should be framed as : h6 was the losing move while Rf6 instead could have led to a forced draw. You keep insisting that this claim is based on unsubstantiated proof or high degree of uncertainty.

  centralfiles: <Kwid> I'm afraid we might just have to agree to disagree with <AK> here. We don't seem to be making much progress convincing him of the merits of 19...Rf6.

Did you ever get a chance to do a deep analysis of 9...h6!? I haven't spent much time on it but I'm not convinced of its merits at this point.

Also I never quite did get over 8...Bb6 9.a4 a6 Which i still think is probably adequate for black and much more "fun" <some aggressive double edged lines> than 8...Bxb4 though you never agreed with me on that one. You supplied positions where white was winning but i found black avoids those positions with best play.

All this is a bit silly though I was replying to the variations you posted as reasons to avoid 8...Bb6 and simply did not realize the strength of 8.b5! which might be just as hard for black as game continuation I.e.

<Random Visitor> <6...Rf8 7.0-0 Qe8 8.b4>

  kwid: Yes h6 was a must for us.
<Since we have no h6 voters but me I have to emphasis that moving our bishop twice just gives the game away. I am not implying that we could win against a sound move order which we should expect with RV's lines as a guidance.

But with h6! and not Ba5? or Bc5? we will have a fighting chance to survive and deny white for being credited to come up with the Traxler refutation line.>

<Probably because no one seems to have anywhere near the fervor in favor of 19...h6 leading to a draw that you and <kwid> (and possibly others) feel that 19...Rf6 leads to a draw.>

You sure got that right.
When I first proposed 19...h6
I said I thought it lost.
(not exactly a winning endorsement)

kwid and centralfiles seem to want to rewrite history.

They also don't take into account,
the real world and the psychology involved.

(I probably would have been a fan of
19...Rf6 had kwid not been on my team,
with him, I wanted to run from it.)

How ironic?
kwid's the reason 19...h6 happened,
kwid's the reason it lost so effortlessly.
(kwid was a big fan of 24...Rxe6,
our guaranteed draw)

(the real moment we were done)

You see part of the problem with move
...19 is you have some responsibility
what you play after it.

19...h6 was never in the mix of a better move or great move.

The only real questions are:

1 Does 19... Rf6 draw?
2 Is there a better move?

...and even if found to be true, it
has no relation to what we actually knew at the time, or who would have been convinced to vote for the best moves.

What we saw wasn't a failure of chess moves, but a failure of psychology.

19...Rf6 draws?
Too bad it never happened.

  diceman: By the way, there is a poster named:

<CharlesSullivan:>

If you look at the 1972 Fischer/Spassky match. He's done excellent work on many games with new computer analysis.

He seems to be a less verbose/better computer/ version of Ayler.

(Wow, you win on both sides of the equation :) )

Maybe he can be recruited for some testing?

I am always willing to give other people projects!

<kwid and centralfiles seem to want to rewrite history.>

Am i too brazen If i can ask you to point to a single instance of something i said that could be seen as rewriting history?

I never took any part in any kind of blame game I did not vote for 19...Rf6 myself, nor do i profess to see its merits without the benefit of millions of silicon transistors.

I am simply maintaining that post game it appears pretty clear that 19...Rf6 draws from a theoretical standpoint. I am happy to analyze other plausible alternatives as well.

I would rather not have to point out some of the more blatantly erroneous posts disparaging <Kwid>s lines that were written with shallow engine analysis and were never recanted.

  centralfiles: <Kwid><all> How many of you would be willing to take on the white/black sides of the Frankenstein/Dracula variation in the Vienna? Blacks results in practice in high level correspondence play have been pretty good I think, with several fine games by Timmerman. Yet theoretically many still insist white is better. So why not have a world game to see if white can get a healthy advantage or is he destined to suffer through an anaconda's grasp just to salvage the half point. It would be nice to see a fine example of how to play the Frankenstein as white.
Nov-30-18  Damenlaeuferbauer: <centralfiles> As a 1.e4,e5 player with the black pieces, I am always ready to take the black side in the Frankenstein/Dracula variation of the Vienna game in correspondence chess. I think theoretically the chances are almost equal. I am eagier to play a Team White vs. Team Black game on Chessgames or a correspondence game against you! Your / Team White's turn!

If we could organize another team game i think it would be much more interesting than the Traxler variation game. Unfortunately Daniel is no longer with us so who knows when chessgames will be able to organize another team game.

If we had two private pages each which can be made to be accessible only to members of one team, then we can set up unofficial game ourselves.

However in absence of such pages it won't be possible to prevent teams from seeing each other's analysis.

Any suggestions?

Starting position should probably be here:

  Tiggler: <kwid> <To close out the discussion if Rf6 holds I searched in support of the white side and could not come up with any winning lines.>

If a member of team white might be permitted to comment on a thread that has produced scores of pages of commentary, mostly about the mythic (unplayed) 19.. Rf6, I would observe that the players of team white have evidently gone away content, but that frustrated team black players continue to fight the good fight. No aspersion on the respective team members: if the result had been a draw no doubt team white members would be the ones here battling over what went wrong!

Under the circumstances, including psychological ones, I don't think <kwid> searching in support of the white side is a substitute for actual team white members doing so, notwithstanding the respect in which <kwid> was known to be universally held by every team white member who is acquainted with him.

  Tiggler: <diceman: By the way, there is a poster named:

<CharlesSullivan:>

If you look at the 1972 Fischer/Spassky match. He's done excellent work on many games with new computer analysis.>

I'd like to follow <diceman> in urging people here to take a look at this poster's exemplary work.

Here is a link to the point in one particular game of the match mentioned where his analysis begins: Fischer vs Spassky, 1972 (kibitz #292),

and this is a later post in which he responds to my request for information about his methods and hardware: Fischer vs Spassky, 1972 (kibitz #303)

A few lines further down is my comment on what he told us. It is short enough to repost here:

<Tiggler: <CS> I appreciate your detailed answer. You should not be even <almost> embarrassed to have spent so long. I would be amazed if your, seemingly comprehensive, analysis in some cases had required less. I know you could not have done it so fast with any current engine without your own skill in forward and backward sliding, as you briefly indicated.

Do you play correspondence chess? I would not want to take you on in that arena!>
