[d]r1b1k1nr/ppp2ppp/n7/3pp3/N3q3/PK6/1PPP2PP/R1BQ1BNR b kq - 0 1

I am surprised, that this hasn't been discussed here! At least my search don't find it. Question: Is -Qxa4 really forced draw?

The best line I found after 1... Qxa4+!? :
Still around +1.5 for white.

[pgn][White "w"]
[Black "b"]
[Result "*"]

On the other hand, d4 isn't any better:

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Guess it's simply already too well known, that Karl Hamppe missed 11.Kb5! with 11.(3.) Kb4? in 1872 against Philipp Meitner over the board.

There's even a Wiki- page of it's own about the game:

https://en.wikipedia.org/wiki/Immortal_Draw

at chessgames.com there's a SF9- commented .pgn:

https://www.chessgames.com/perl/chessga ... 160&comp=1

In F17.ctg 11.Kb4 has a !? and yet it's the main line- move, that's a hole in this book, 11.Kb5 is tournament- move (green) too, but without probabiltiy of active play, that should be changed to 100% and Kb4 should get a ? to be blocked from active play.

Here's CFish with Pure NNUE Eval after a backward of the 11.Kb4- line stored in F17 too and Vincent gave up to 17. too:

Position after 11.Kb5! (instead of Kb4?):

Good found, one should tell Hubert Bednorz :)
Yet Anton Stadlhofer, who posted Harte Nüsse most of the times will probably know already,I guess. Search in CSS online doesn't go further back then 2008, as it seems.

Nostalgic regards
