Chess 960 possible problem

Nice Xmas present for you Thibault- a possible server problem :P

Not sure if I am doing something wrong or it is the server.

When I download a Chess 960 game and attempt to start engine analysis through fritz interface, I have only just realised that the downloaded game does not recognise 'Chess 960' or even the traditional version castling.

Only when I set the position up and select the four castling options will the game start analysing castling options.

FEN used in encoding the starting position does not include castling information. You can add manually "KQkq" in the FEN line at the end, in the PGN file.

Fritz uses a non-standard encoding of the castling rights for Chess 960, with starting positions of Rooks not on A and H files.

Fritz should recognize castling rights, but the information is not included in the file. This is most likely an accidental omission, or it might have been done to avoid messing with X-FEN and the non-standard Fritz solution.

At this rate I'm becoming a helpdesk. :?

Hi Garvin and Mladen.

You mean the FICGS PGN files for chess 960 are incomplete ? If this is the case, I'll correct it soon.. Thanks !

Chess 960 possible problem continued

Hello Thibault,

Have just noticed recently that the 'bug' of the server not recognising castling rights in 960 games still exists.
