Eh

Yes, that link doesn't quite seem to be showing what David intended?

David S's above post is apropos of a statement (in the thread he now links to, below) -

"It is quite clear that the Karlsbad [1911] players were far more prone to severe errors than contemporary players."

And I tend to agree with David's explanation, further above, in this thread despite GM Matt Turner remarking -

OK, then I don't understand that at all then

Edit - I only changed one letter - ''u' to 'a' in the initial "David". (Honest, guv.)
Edit - I had to do it again to make sense of reference to a link.

Sorry, completely the wrong link. I have corrected the original post.

I intended to refer to www.ecforum.org.uk/viewtopic.php?f=2&t= ... 83#p260883.

Scroll down to my post.

Whilst these look similar, I think the Karlsbad mistake is much more understandable.
Spielmann (the player a pawn down) initiated an exchange of Rooks which would have led to the simple draw and just missed the King move
In the MVL example, it is the player who is a pawn ahead who initiates the exchange, so what did MVL think Radjabov was up to? With 19 minutes left you would have thought he would give it some consideration and even a moment's thought leads to the conclusion that the immediate exchange loses.

Compare and contrast the following two blunders:

[Event "Opera Euro Rapid"] [Site "?"] [Date "2021.??.??"] [Round "?"] [White "Vachier-Lagrave,M."] [Black "Radjabov,T."] [Result "0-1"] [SetUp "1"] [FEN "8/8/5pk1/6r1/6R1/6K1/8/8 w - - 0 1"] [PlyCount "6"] 1. Rxg5+ $4 (1 Kf3 $11) 1... Kxg5 $19 2. Kf3 Kf5 3. Kf2 Kf4 0-1

[Event "Karlsbad"] [Site "?"] [Date "1907.??.??"] [Round "?"] [White "Spielmann,R."] [Black "Duras,O."] [Result "0-1"] [SetUp "1"] [FEN "8/8/5pk1/5r2/R7/5K2/8/8 w - - 0 1"] [PlyCount "2"] 1. Rf4 $4 (1. Kg3 $11) 1... Kg5 0-1

Whilst these look similar, I think the Karlsbad mistake is much more understandable.

Thanks, Matt & David.

From another (linked) thread -

I noticed that someone at ChessBomb was trying to defend MVL by saying it was a mouse slip.
Of course these things must always be considered in an online game but in this case that is not really an option.

8/8/5pk1/6r1/6R1/6K1/8/8 w - - 0 1

You cannot 'mouse slip' the Rook to anywhere but Rxg5.

It was just an online boo-boo by MVL. It happens, the coincidence in the position from Carlsbad 1907 makes it entertaining. Good spot.

The good news regarding MVL's 'mouse slip', this is becoming so notorious somebody somewhere will not (or should not) make the same mistake.

Thanks, Geoff, and yes it was a "good spot" by eagle-eyed David S.
