World Chess Championship (Game 8)

[AdminX]

I am referring to the 11th move by white.

What about it?

It was written as "Ndxb5" when it should have been written as "Nxb5" because the other knight on c3 was pinned to the King, and only the knight on d4 could legally take the piece on b5. Disambiguity notation should only be used (I think that is the pgn specification) when there IS ambiguity.

Oh, well that is the way Chessbase 10 is displaying them when I do copy game, after I enter the moves from the website.

This game will surely end in draw, I'm making this prediction here ahead of time.

Arena GUI is displaying it properly (as 11. Nxb5)

On Playchess, Foidos as well as ChessOK, it's given as 11. Ndxb5

I guess there is a way to change this, but I don't have time to check right now.

Unless the pgn specs were recently changed, Chessbase is wrong. Perhaps they are knowingly wrong because they are making it easier for the reader who may not be aware of the illegality of one of the knight moves.

From the 1994 PGN specs at

http://www.very-best.de/pgn-spec.htm

Code: Select all

... An example of this would be a position with two white knights, one on square c3 and one on square g1 and a vacant square e2 with White to move. Both knights attack square e2, and if both could legally move there, then a file disambiguation is needed; the (nonchecking) knight moves would be "Nce2" and "Nge2". However, if the white king were at square e1 and a black bishop were at square b4 with a vacant square d2 (thus an absolute pin of the white knight at square c3), then only one white knight (the one at square g1) could move to square e2: "Ne2".

Thanks for the posts Ted.
Anand is going for the win. No castle. Will it pay off.

Best to you,

Gerold.

Kramnik playing attacking chess here... with f4, not allowing Anand's knight to come into his side of the board. Also, avoids Qg5 for now (if ever it was planned by Anand). But, by doing so, Rybka 3 on ChessOK says that he might have lost some of the edge that he had till then. Move suggested by Rybka3 was g3.

For Anand, suggestion/continuation by Rybka3:
15... Rd8 16. Qe1 Qb6+ 17. Rf2 Kf8 18. Kh1 Kg7 19. Qe2 f5 20. Raf1 Ne7 21. e5 Qc6 22. Nb5 Rd5 23. Nd6 Nc8 Rybka3_8cpu (0:02.39)+0.10|d19
