The most were pawns on the first or last row and the rest 201 errors were more than eight pawns of one colour.

The 1714 that I reported was actually based from my collection of single bm positions. Already emailed Dann about this figure.

Let me check the orig file if I can match your figure.

Here is the summary.

Code: Select all

Position  NoBM  IPawnLoc  INumPawn  INumPiece  IPaAndPie  IFen
 1112569    46      2870       201         16         31    27
NoBM = No bestmove
IPawnLoc = Illegal pawn location, at 1st and 8th rank
INumPawn = Illegal number of pawns, could be wp > 8 or bp > 8
INumPiece = Illegal number of pieces (not pawns), could be wr > 10 and others
IPaAndPie = Illegal counts based on pawns and pieces combination, could be wr = 3 but wp = 8. The positions here are not in INumPawn and not in INumPiece.
IFen = Illegal Fen, this is based on the Python-Chess Library (PCL) that I use. I save the fen whenever that method set_fen(fen) raised an error.
Looking at the positions, these are fen with qk castle field for example. Also 2 successive digit in the row like /1K1P4/P4B11/8 w

It could happen that positions in INumPawn can be found in IPawnLoc.

Great work!

Dann: Will you be providing a revised version without the bad positions?

Many thanks.

Ferdinand , could you clean up the file here please : http://www.talkchess.com/forum/viewtopi ... 107#615107
1) Sometimes, there's text before the FEN/EPD, is it possible to remove it automatically ?
2) A lot of positions are duplicate but different comments after the FEN/EPD, is it possible to hold only 1 (the longest string) ?

Thanks :D ,
Vincent
